Report of the month - March


History: The nature reserve "Schlammwiss" was founded in 1982 by the foundation"Hellef fir Natur" (HFN). Afterwards the group "Letzeburger Natur- a Vullenschutzliga" (LNVL) founded the station "Schlammwiss". The station is leaded by the "centrale ornithologique Luxembourg" (COL), a part of the asbl. Natur & Emwelt. Due to the fact that Luxembourg doesn't have its own bird ringing central, we work in cooperation with Royal Belgian Instutitute of Natural Sciences. Therefore, we use rings from the Belgian Museum of Natural Sciences.


Location: The bird ringing station "Schlammwiss" is located in Luxembourg, between the communities Schuttrange & Munsbach. The nature reserve is part of the 375ha big Syrvalley and is an extremely important Natura 2000 zone. The reserve is periodicly flooded due to the Syr river, which is an important generator of biodiversity.


Research area: Around 30ha are used for researche, on a length of 1km and a width of 30-120m. The main area is covered by reeds and wetlands (20ha). Furthermore, the resarch area is subdivided and caracterized by an orchard, a forest, several ponds distributed throughout the reedbed and a purification plant (SIAS). The main techniques employed are mist nets and rail traps in order to realize population estimates (i.e. breeding population, migration, overwintering population) and survival estimates by Capture-Mark-Recapture. There are several projects running in the nature reserve and visitation are possible.


Summary of the ringing activity this month

In march, the bird ringing station "Schlammwiss" caught about 855 birds of 34 species. This number is subdivided in 581 E, 187 W and 87 K. None bird foreign origin has been caught.


The total amount of birds for the month  is higher than the average amount of birds caught in february at the station. The graphic below shows the average amount of birds for each month during the years 2001-2014.

Recapitulation of the waterpipit project 2017/18

Grafic 1

This is a recapitulation of the waterpipit project this winter 2017/18. You can find more information about the project here.


In total, we caught 115 Anthus spinoletta this winter . This is the second highest number of this species capured at the birdringingstation "Schlammwiss" since 2000. The highest number was with 117 captures in 2015/16.


Grafic above: About 72,2% of the birds this winter were captured for the first time (E) and 15,7% are controlled birds that were ringed the years before (K). Furthermore, we recaptured 14 of those birds again this winter (W).


Grafic right: The majority of controlled birds (K) were ringed last winter 2016/17 and 2015/16. Furthermore, one individual was ringed 2013/14 and one 2012/13. This bird is older than five years.


In summary, we have spent about 12 hours ringing, plus several hours of working on the site.

Max exploring Ottenby Bird Observatory

Hey dear Birders and Ringers,


Since I have now been here at the bird observatory in Ottenby, Sweden for nearly one month and had an interesting and funny time, I wanted to share a bit of my experience with you.


The observatory itself is situated on the most southern tip of the island Öland on the eastern coast of Sweden. The island is shaped by extensive cultural landscape and plays an important role as breeding location for many agricultural bird species such as Montagu’s Harriers or Barred Warblers. Following the Swedish eastern coastline southwards, migrating birds from northern and central Scandinavia are gathering every year on this cape to stop and forage to do the big step over the east Sea. That is what makes it a excellent place to study bird migration, from goldcrests to sparrow hawks …


Regarding the actual bird catching, the observatory has been running a standardized program running with usual mist nets and Helgoland traps since 1946. The results of this long study are very interesting and meaningful especially concerning population fluctuations of diverse bird species. Apart from the standardised program during the mornings, waders are caught in traps along the shoreline (dunlins, knots, ringed plovers, curlew sandpipers, little stints etc.) until the end of August, raptors such as rough-legged and common buzzards in traps and Tengmalm’s and long-eared owls, different duck and gull species during the night.


Over the last weeks, migration has been constantly increasing, we had until now one day with over 600 catches per day. The catching rate is however strongly depending on the actual weather situation on the cape or in the region. Common species caught are among others robins, goldcrests, willow warblers, chiffchaffs, blue and great tits, pied and spotted flycatchers, sedge warblers, lesser and common whitethroats, blackcaps, white and yellow wagtails, song thrushes and sparrow hawks. However the composition was of course constantly changing over the last weeks. Quite rare catches were so far a merlin, a grey partridge, red-breasted flycatchers, yellow-browed warblers, one dusky warbler and a little bunting.


Time here is passing quite fast since there is a regular daily routine. Nonetheless the good atmosphere within the ringing team, the awesome Swedish food (coffee and cake seriously every day), the variation of bird species and last but not least the special landscape around the cape makes every moment special.


I am really looking forward to the next 3 weeks when migration is increasing, to see some more new species especially northern birds like common redpolls or lapland buntings and maybe one or the other surprise. I am grateful for the experience so far and the knowledge which is generously and professionally passed on. Ett stort tack till Ottenby fågelstation! A lot of knowledge and information regarding bird sex/age identification, scientifical work or just about the daily ringing is also shared on the bird observatory’s homepage !

Pictures may tell more than words … (wow that sounded cheesy) Of course I would really recommend visiting the place to anyone who can distinguish between a robin and a red breasted flycatcher !


Greetings from Ottenby!

Observation of Eurasian Crag Martin (Ptyonoprogne rupestris) in Schlammwiss Nature Reserve

On the 10 April 2016, one of our ringers was in the reserve when he made a very interesting observation of a putative Crag Martin (Ptyonoprogne rupestris).


The bird was seen flying from SW to NE over the reserve. The identification was based on several criteria and past experiences of the ringer observing the bird. The criteria were flying jizz of the bird, squarish tail, white spots on tail, dark under wing coverts, dark undertail coverts amongst others.


If accepted by the rarities committee of luxembourg this would be the first ever sighting of this species in the country. Well done to our team for the sharp eyes!

Report from May to July

This report will focus on three month (May; June; July). As we had technical problems with our computer program, we did not manage to continue the monthly reports. The main issue of this report will be the monitoring of the local breeding birds and the first migrant species.


Over the three month period, we ringed 5.329 birds. Within these birds we had 4.349 first captures, 781 recaptures (birds ringed this year) and 199 control captures (birds ringed another year or at a foreign bird ringing station).

The main species during the monitoring were, the Reed (Acrocephalus scirpaceus) and Marsh Warbler (Acrocephalus palustris) and the Grasshopper Warbler (Locustella naevia).


Codes  First capture (e) Recapture (w) Control capture (k)
Reed Warbler  624 110 27 
Marsh Warbler 200 171 45
Grasshoper Warbler 54 17 3


The uncommon species during the breeding bird monitoring were three Melodious Warbler (Hippolais polyglotta), one ad. female and one juv. European pied flycatcher (Ficedula hypoleuca), an ad. female Green Woodpecker (Picus viridis) and one juv. Long-eared owl (Asio otus).


Usually the first migrants arrive around the 15th of July.  The first migrants to arrive are either species taking the eastern migratory way, Marsh Warbler (Acrocephalus palustris), Red-backed Shrike (Lanius collurio) or lesser withethroat (Sylvia curruca), or species which start their migration quite early as the Sedge Warbler (Acrocephalus schoenabaenus) or the Great Reed Warbler (Acrocephalus arundinaceus).


Another interesting species was an immature Lapwing (Vanellus vanellus).


The most interesting species for this three month period was an adult Blyth’s Reed Warbler (Acrocephalus dumetorum), which stayed singing from the 27th of June until the 9th of July. It was the second time for this species to be recorded in Luxemburg. The bird was captured twice, once on the 28th of June and a second time on the 6th of July.


During the three month period we had two people working daily on the ringing station, furthermore we had several school classes coming to visit the ringing station.



Thanks as usual to the team for the effort they make in our station .

Expedition in the Arctic

Autor: Charel Klein

Visiting the arctic was always one of my childhood dreams.

This summer, I had the great opportunity to join scientists who visit Greenland every year as part of a long term project. We worked on a long term study on lemming cycles in North-East Greenland. With three other people, from France, Germany and Switzerland, we spent 2 weeks in the biggest national park of the world. The project is carried out in the Karupelv Valley (72.30 N; 24 W). With 3542 km2 the island of Traill is bigger than the surface area of Luxembourg (2586 km2).


The main work to carry out was to observe Sanderlings nests (Calidris alba) of which we find the first pairs in the area. We had to visit the nests every second day, mark the colour code of the adults, check if they got predated or not, ring the chicks when they start to run around in the tundra and to collect the tiny tags from under the sanderlings' nests after they finished breeding.


We had to also check the population of predators in the research area. Therefore we visited the old burrows of Arctic foxes (Vulpes lagopus) and counted the number of Long-tailed Skuas (Stercorarius longicaudus), Parasitic Jaeger (Stercorarius parasiticus), Gyrfalcon (Falco rusticolus) and Snowy Owl (Bubo scandiacus). Futhermore we searched chicks of Long-tailed Skuas to get some feather samples for an isotope research.

In two weeks we hiked about 200 km and checked all the important points in the research area. We slept in tents and spend our time eating and chatting in an old trapper hut from the thirties. Our shower was the whole Kong Oscar Fjord with Icebergs and as toilet we had to ditch a hole near a streamlet. We used flowing water from glacier and snow water to drink or cook and eat trekking food from cans (some from 2005 !!!). During the time in Greenland we had 24h light and between 0-15°C. The number of midgets was incredible and torturing! not even comparable with the deep jungles.


I was very happy of the different bird species that I have seen up here, the beautiful flora and all the big mammals like Arctic foxes (Vulpes lagopus), Musk ox (Ovibos moschatus), Polar Bears (Ursus maritimus) and seals.

Birdringing at Kaiserstuhl

Christian Stange is ringing a little owl (Athene noctua)
Christian Stange is ringing a little owl (Athene noctua)

Already since two years one of our members of the Birdringingstation 'Schlammwiss' is working together with Christian Stange at Kaiserstuhl / Freiburg. During the autumn and winter the main work is the maintenance of the biotopes. For spring they start to control the nest boxes of little owls (Athene noctua) and hoopoes (Upua epopos) and to ring the juveniles. 


This year they checked the area around Ihringen and controlled about 12 nest boxes of hoopoes and 1 box of the little owl. 


Most of the hoopoes started already with the second brood. So most of the nest boxes which are inside of a vineyard cabin were empty or with eggs. We checked the empty boxes if any birds breed inside and checked what happen with the juveniles (Are we too late and they flew out? Did something happen? Did they breed?). We also checked the nest boxes around the vineyard cabin which are against the breeding pressure to see which birds used it. 


To check if something is inside of the box we checked the ground in front of the hole for faeces and smell on the hole to determine the present of juveniles (>> penetrate smell for the defence of the juveniles against predators like the beech marten (Martes foina)). We also check for marks on the hole to see if a beech marten already tried to get in. Than we close the hole and go inside of the cabin to get the juveniles. Before we open the box we shine with a light inside of the box to see if there are juveniles or the female with eggs. Inside of the box we check the condition of the nest box and have a look if we can find some remains of their food. 


We had only two nest boxes with juveniles which had the right size to ring. More than the half of the boxes had only eggs which mean that the hoopoe started with the second brood. 

We also we checked a nets box of the little owl which was impossible for Christian to check earlier. We found one juvenile inside of the box and another one outside in a natural hole.


Same as the population of hoopoe Christian Stange is also responsible for the little owl population at Kaiserstuhl. Both species need the same area and conditions to live. For the moment there are about 56 pairs with 160 juveniles at Kaiserstuhl. 


To the end we installed a new nest box for the scops owl (Otus scops) which has been seen and hearing a bunch of times at this area.

Hoopoe project at Kaiserstuhl / Germany


One of many vineyardhuts at Kaiserstuhl which the hoopoe use to breed
One of many vineyardhuts at Kaiserstuhl which the hoopoe use to breed

The Hoopoe (Upupa epops) breeding habitat was in good condition before forestry management started in Central Europe.

The Hoopoe had ideal conditions to breed  with orchards, meadows, wooded vineyards and open forests. The main distribution of this bird was from the south to the east of Europe.


With the beginning of  forestation of nutrient-poor soil in the 19th century, many biotopes disappeared. It declined in the 20th century with the growing livestock farming and the draining of meadows. Furthermore, the meadows became bigger because farmers started to use mineral fertilizer and liquid manure to fertilise the new fields. Fast growing grass needed to get mowed fast and this activity destroyed the foraging grounds of Hoopoes. Also, the use of insecticides in the fields, polluted the soil  Eventually the insects that Hoopoes feed on and fed the chicks on created abnormalities in the eggs and health of the birds, this happened mainly in the 1960's.

Not only the insecticides where having negative effects on Hoopoe populations, but also the breeding grounds of the Hoopoe was changing. The hoopoe is a cavity breeder and needs holes in big trees and in walls. Old fruit trees and big thick willows which are good breeding places for this bird were removed from the landscape. The destruction of orchards and the change in which fruit trees were managed from low-stem trees to high-stem trees left no cavities in trees where Hoopoe can breed.

Only  few pairs of Hoopoe survived in Rheinland-Pfalz till the 1980's. All of them used holes in walls to breed instead of trees. Although more than 100 pairs of Green woodpeckers (Picus vidris) were drilling nesting holes in trees still the Hoopoes were not utilising these cavities.

Trip to 'Federsee'


Three members of our Schlammwiss Team (Dave, Charel and Max) visited the Federsee lake in southwestern Germany the 26th and 27th of May. The lake itself is surrounded by a spectacular reed belt and vast moorland, the water surface itself, which is only about 2 meters deep, is only accessible by a 1,5 km long wooden boardwalk. Since the area is an important hibernating, resting and breeding site for many bird species among others 200 breeding pairs of Whinchats and 18 breeding pairs of Marsh harriers (according Nabu 2014), it has been declared a Special Protection Area.


We’ve seen lots of interesting species, some well known as Reed Warblers, Savi’s Warblers, Great Reed Warblers and Reed Buntings, rather uncommon species such as Whinchats, Common Terns, Ruffs and marsh harriers. Furthermore we were quite lucky to observe rare migrants such as six female red-footed falcons and one Arctic Tern!


All in all it was a perfect Weekend despite of rain and I strongly recommend visiting the spot!

Research of Woodlark Lullula arborea on the former military training field at Münsingen

With upcoming conflicts of wild boars around protected areas such as the core zones of the biosphere reserve ‘Schwäbische Alb’, the research centre for wildlife at Aulendorf has launched a project to study its ecology and behaviour more closely.  One part of the research project is to determine the influence of its activity on important bird species such as woodlarks and its habitat preference. The main observations are taking place at the former military training field at Münsingen, which is part of the biosphere reserve.


Populations of woodlark across Europe have been in decline, with habitat loss in favour to agricultural land as major cause. However, agricultural development and intensification has not been affecting landscape and wildlife at the former training field here in Münsingen and periodic training manoeuvres didn’t seem to have bothered the local woodlark population during the last century. The right mix of habitat structures such as sparse vegetation with areas of bare or disturbed ground for foraging, patches of longer grass which provides cover and the vicinity of woodland for song perches or security is commonly found here. Nowadays the maintenance of an open landscape here  is largely due to sheep grazing, but also wildlife such as roe deers, wild boars and hares do their share.  

Apart from woodlarks, one can see a vast abundance of common bird species like red kites Milvus milvus, European pied flycatchers Ficedula hypoleuca and European stonechats Saxicola rubicola and furthermore rarities such as whinchats Saxicola rubetra and northern wheatears Oenanthe oenanthe.  


My objective for the next two months will be to determine whether rooted patches created by wild boar are frequently used by woodlarks and form important feeding grounds, especially during the breeding season. And as a secondary goal, I will be detecting habitat preferences and collecting information about the breeding territories.


Since the beginning of April, I started observing woodlarks and am really looking forward to gain first results.


I strongly recommend visiting the biosphere reserve and especially the former training fields here at Münsingen to all nature and biodiversity lovers!


Yours sincerely,

Max Steinmetz

Turkeytrip part 1

In May 3 members of the schlammwiss team (Joseph D, Raoul M and Charel K.) went to Turkey for 11 days. Turkey was our choice because (like the most ornithologists) some of the team have a list of birds they've in the Western Palartic and they had some missing in the eastern part.


We started our trip in Antalya and drove until the Lake Van. For the new and dangerous parts (Göksu Delta, Camardi, Osmanyie, Birecik, Syrian border + desert, Nemrut Dagi) we had the Faroese man Silas O. as guide with us. He knew a lot about the areas, birds and culture. We enjoyed the time with him and learned a lot about the culture and country!


Most of the time we drove the car to find new birds and to get new photos. We started at sunrise and went back to the hotel as sun set (everyday a different hotel in another city).


In summary it was a great birding trip with 237 birds (see list below) and beautiful landscapes! (click to see all the photos)

Ringing in April is comparable to the weather situation in April, this means that there is a mixture of sunny, foggy and very rainy days. Usually migration is very similar, a great diversity of species can be detected.


All in all in the Month of April we caught 647 birds, from which 435 were first captures, 133 recaptures from 2015 and 79 control captures birds not ringed in 2015. The diversity with 51 different species is very good for the Month of April.

Typical birds for the Month of April have been the first Reed and Bush Warbler species: Sedge Warbler (Acrocephalus schoenabaenus), Reed Warbler (Acrocephalus scirpaceus), Savi's warbler (Locustella luscinioides) and Grasshopper Warbler (Locustella naevia). Furthermore we caught the first Bluethroat (Luscinia svecica), the first Nightingales (Luscinia megarhynchos) and a spotted crake (Porzana porzana).


From a migrational point of view most of the birds have been Blackcaps (Sylvia atricapilla) with 153 individuals. During the first two weeks of April migration was still low with an increasing diversity and the last two weeks were marked some very interesting captures: 2cy male Whinchat (Saxicola rubetra), the first Wyrneck (Jynx torquilla) and a very early Common Redstart (Phoenicurus phoenicurus).


 This month special has definitely been the Greenshank (Tringa nebularia) which was a first for the Ringing station.


Thanks as usual to the team for the effort they make in our station .

Tengmalm's Owl


After two bad seasons in 2013 and 2014, we accompanied this year two experienced ornithologists who controlled nestboxes of Tengmalm’s Owl (Aegolius funereus) in a forest of the Hunsrück in Rhineland-Palatinate. Because of the good food supply this year, the Tengmalm’s owl is likely to experience a better breeding season. This nocturne species has a body height of only 24-26 cm and it primarily subsists on small rodents such as mice. Its habitat consists of low mountain ranges between 450 m and 800 m above sea-level. The Tengmalm’s owl mainly prefers coniferous forests mixed with leaf trees including old nesting holes of the Black Woodpecker. Unfortunately, the brood of the Tengmalm’s owl is threatened by martens which climb up trees and eat their clutches.

Depending on the weather conditions, the females generally start breeding in April. A few chicks had hatched already when the ringer checked the nestboxes.  In this ringing session only the females were ringed. A recapture of a female or a nest-ringed young owl is rare but there are already a few recaptures of Tengmalm’s owl in Belgium. They hatched and were ringed in the region Eifel, which shows that this owl species migrates between different low mountain ranges.

Report of the month March

Ringing this month was definately marked by the progress of the ongoing Water Pipit Project, in total 50 Water Pipits (Anthus spinoletta) were captured, 40 new and 10 recaptures. Some of the recaptures have been wintering every year in the reserve for the last 4 or 5 years at least!. You can follow the progress of this project on Schlammwiss website. (click for more information)


In total, 435 birds were ringed and recaptured of 32 species. It was a good month compared to other years and as usual more spring migrants show up the first time during this month.


Some of these are White Wagtail (Motacilla alba), Blackcap (Sylvia atricapilla), Stonechat (Saxicola rubicola) (2 birds ringed and recaptures from each). 1 Skylark (Alauda arvensis) and 1 Green Sandpiper (Tringa ochropus) were also first of season. As expected, the top species for this month that peak the migration back to their breeding grounds in this period were Robin (Erithacus rubecula) (64 ringed and recaptures), Dunnock (Prunella modularis) (55 ringed and recaptured), Chiffchaff (Phylloscopus collybita) (28 ringed and recaptured) and Reed Bunting (Emberiza schoeniclus) ( 95 ringed and recaptured).


We also noted a small movement of Wrens (Troglodytes troglodytes) with 18 birds ringed and recaptured.


Other interesting species ringed were 3 Firecrests (Regulus ignicapilla), 1 Short toed Treecreeper (Certhia brachydactyla), 3 Redwings (Turdus iliacus), 2 Coots (Fulica atra) and 2 new Water Rails (Rallus aquaticus).


The special threat for this month was a Little Grebe that we caught in the net while flying from one pond to the other!! We did not ring a lot Little Grebes (Tachybaptus ruficollis) during the years for obvious reasons as this species don't fly around but prefer the water where they are well adapted to dive and swim, so finding the bird in the net was a surprise.


Although usually the month of March is a quite one for bird ringing as most of the migrants or summer visitors have not arrived yet, it is always a pleasure to see the first spring migrants and the first signs of breeding after the long winter months.



Thanks as usual to the team for the effort they make in our station .

Ringday 2015

Participation in the Ringday 2015 organised by Institut Royal des Sciences Naturelles de Belgique at Genk Belgium

Members of Schlammwiss Ringing Team met early on Sunday 22 March to hit the road to Genk in Belgium for the annual Ringday organised by the Belgian Royal Institute of natural sciences.Apart from the regular bird ringing and other scientific projects, the Ringing team makes sure to attend these sort of conferences to keep in contact with other ornithologists and update itself on recent studies and research on birds and bird ringing.

We arrived around 11 am where we attended a guided tour of the Het Wik nature reserve. An interesting biotope with marshes and reed beds surrounded by mixed forests which provide excellent habitat for birds. We were given information about ringing and management on the site.

At 2pm we started with the first talk which was about the ringing results of the reserve Het Wik, it followed by a very interesting talk about why bird ringers should take measurements on birds , what the measurements means, when and how. This talk solidified our beleifs and our insistance to take regular and accurate measurements. We were given several examples of cases where the measurements makes difference in species , populations and races of particular bird taxa. Measurements also help to determine sex and age in some species. A fine example is weight of a bird in comparison to fat levels, this can show whether the bird is migrating or not.

The third talk was also of high importance for all bird ringers it concerned the moult of birds, a must know to all bird ringers and trainees that ring birds regularly. Bird moult can tell a lot, it shows different stages in a birds life so knowing how birds moult is one of the biggest tool for ringers, ornithologists and scientists. We are used to ringing passerines so hearing a talk about catching and ringing waterbirds for 10 years was interesting for us.

It concerns the reserve of Sint Agatha Rode where they use a water cage trap with food to attarct ducks , of special interests was the information about the recaptures and the data provided from this activity as there are not a lot of ringing stations that focus on ringing water birds.

The last talk was about building a bal chatri trap for birds of prey. This is a special trap that needs a special permission to operate.

Overall, this ringday was a huge success from the social aspect for our team and most importantly for the opportunity to learn and share knowledge on birds and bird ringing. Member's of Schlammwiss team have also attend last year's Ringday and a symposium for birdmonitoring at Mainz University in November 2014.

Pallas's leaf warbler

On thuesday the 19. march we (Jim, Raoul, Charel and Guy(Birdringingstation 'Schifflange')) went to Belgium to see the Palla's leaf warbler (Phylloscopus proregulus). We found the bird together with Goldcrests (Regulus regulus), Firecrests (Regulus ignicapillus) and Chiffchaffs (Phylloscopus collybita) in a big wetland area.

Update Waterpipit 2

Description of the Water Pipit project --> click here




On the weekend of the 6th and 7th March we opened the nets again in Schlammwiss site and for the first time in Mensdorf. We had a beautiful spectacle of over 50 Water Pipits flying over the reeds for some time at Mensdorf checking where to land to roost. Most of them landed on a tree or went down in the wetlands before they flew again into the reeds. We had the biggest catch so far for this project in Mensdorf and the biggest catch ever of Water Pipits in one go for the reserve!




  • 41 waterpipits
    • 34 new captures
    • 7 recaptures from 2013 & 2014
  • 3 birds not tagged because too weak (muscle and fat very low)



  • 44 birds tagged
    • 30 new Water Pipits
    • 14 recaptured Water Pipits from 2013 & 2014
  • Need 6 more specimens


For every activity we didn’t open more than 5 netlines! After the ringing activity we closed all nets correctly and bring the Pipits back to their sleeping place.



Thank you to the team! For helping me tagging the Water Pipits until 2 a.m!

Report of the month - February

The month of February is usually one of the slowest ringing months of the year.

This is usually because of two main reasons:

One is the maintenance work in the reserve that takes priority on bird ringing and secondly is that the spring migration has not started yet and the only birds around are those that survived the cold winter.

(--> more about the report of the weather see below)


In total, we ringed 48 birds and recaptured 100. The usual pattern was observed again this year , first spring migrants to arrive, as every year, were Reed Buntings (Emberiza schoeniclus), 8 in total in the last two weeks of the month. 1 Mallard (Anas platyrhynchos) was also ringed .

The Water Pipit (Anthus spinoletta) project has started so 2 new birds were ringed and 4 recaptured.

Other interesting captures were 1 Goldfinch (Carduelis carduelis) quite out of season, 3 Moorhens (Gallinula chloropus) and 3 Fieldfares (Turdus pilaris) that were attracted to the apples in the orchard. The two Middle Spotted Woodpeckers (Dendrocopos medius) and the Nuthatch (Sitta europaea) are still hanging around the feeders in the forest. The usual winter birds are still around with 44 Blue Tits (Cyanistes caeruleus) ringed and recaptured, 6 Yellowhammers (Emberiza citrinella), 3 Willow Tits (Poecile montana) , 7 Cahffinches (Fringilla coelebs) and 10 Robins (Erithacus rubecula) .


We thank the team for the maintenance work they performed this month on the reserve.

First signs of spring 

In Mid-February, we were able to observe the first signs of spring. At the end of November, the last cranes migrate to their wintering grounds in the south of Spain: this for most of us heralds winter. In contrast, when in February the first cranes are migrating back to their breeding grounds in the north of Germany or Sweden, some of the optimistic ornithologists claim that spring has started.


As Luxembourg is situated on a 100-kilometre passage on the migratory track of the cranes, we have the opportunity to observe big groups of up to 1000 individuals migrating to the north. Last week, temperatures have risen by 5°C; this increase was a signal for up to 20 000 cranes to start their migration. This spectacle was observed by a lot of hobby ornithologists including myself; this means that between the 21 and the 23 of February I was able to count up to 5000 birds heading to the north. Not only cranes announce the spring, other indicators were singing like blackbirds and chaffinches; these two species hardly migrate, which explains their presence on the feeders during winter.


Another species introducing the spring is the white stork. The first arriving white storks are always males, they are first because they need to occupy their territory and nest. Waiting for the female birds to arrive, they work on their nests in order to present a well-formed home, on which both of them can raise their chicks. A highlight for Luxembourg was the first breeding pair of the white stork in 2012. This bird species was extinct for decades, but it seems that the population is rising. Last week the first storks arrived and excited a lot of ornithologists.


Apart from the aforementioned species, some of the most impressive birds of prey have also returned. The first red kites were observed in January. Last week, we were able to observe our local breeding couple, starting to rebuild their nest. In addition to the red kites, we observed the first reed buntings. This bird species, which uses reeds to feed and to raise their chicks benefits from the last grains on the feeders to survive the month of March. As reeds start to grow late in March, reed buntings depend on remaining grains which they find along fields or on the feeders.


An additional spring species is the woodlark (Lullula arborea), which started singing in the vineyards last week.

Ecological Succession of Wetlands



The process whereby one plant community changes into another. It involves the immigration and extinction of species, coupled with changes in the relavtive abundance of different plants


Crawley 1997


The nature reserve „Schlammwiss“ in the Syrvalley near Übersyren consists of a vast reedbed, which has naturally established itself around several ponds, and a big marsh area. These two vegetation types would, without any maintenance of an open landscape in terms of a periodical mowing/cutting or extensive pasturing, as we would find it near Mensdorf, be exposed to the natural succession of plant communities. Wood such as several willow species, alders and elms, which can cope with moist soils would claim these permanently and seasonally flooded areas and thus displace the desired vegetation.


In order to support a certain structural diversity consisting of meadows, reeds, sedges, some shrubs and trees and so favour linked habitats for diverse insect and bird species, it is essential to carry out maintenance measures. This includes on the one hand removing the spreading wood and bushes especially in the reed area and on the other hand regularly mowing the marsh area to keep it open.


Due to the heavy snowfall during January, which has flattened the whole reed and sedge area, accessibility was given and one could easily remove all shrubs and woods. Furthermore a committed participation of many members of the Schlammwiss-team as well as many helping hands from the “Fit by Nature” activities enabled to do the job.


Many thanks to our volunteers and Alain Maury (and co.) !

Update Waterpipit 1

Description of the Water Pipit project --> click here


·        Water Pipits (Anthus spinoletta) have been observed roosting in 'Schlammwiss' Nature Reserve since 2000.

·        Since 2012 we started ringing these birds in the roost, thus collecting various data and information on these birds.

·        In winter, Water Pipits usually spend the day in open wet pastures catching insects and in the evening they gather in small flocks and roost in reedbeds with thick undergrowth vegetation.

·        Until this day, we still don't know the origin of our wintering birds. With this project we aim to catch and tag with small GPSs 50 Water Pipits, so that hopefully we will recapture some of them again and get a better picture on the whereabouts of these birds. Our aim is to learn where these birds breed, their migration route and the roosting places they use. To get all this data we need to recapture the birds again in the first three months on 2016.


In the last two weeks, volunteers and members of the schlammwiss team, have been busy preparing and maintaining the sites (reedbed), where the nets will be set up for this project. Some work has already been done last autumn like cutting trenches in the reedbeds to set up the capture area.


We are very cautious and have been discussing where to set up the nets to minimize as much as possible the risk that these birds will abandon the roosting site. This is why every step of the work is meticulously taking time and done under supervision of the project coordinator and the ringers. Apart from the roost in Schlammwiss nature reserve, there is also another roost of Water Pipits that we are working on in Mensdorf area. We have already prepared 5 trenches in Mensdorf area to set up nets. With this new site we can work for two consecutive days but use two different sites to minimise disturbance.


We’ve got 50 Pinpoint GPS from Biotrack that we received on the 25. February for this waterpipit project. They are working different from the geologs that we used for the reed warbler project.

We can use the GPS for 600s. We tested one GPS in the field to find out

·        How long does it need to record one reading?

·        Does it make any difference --> outdoor (wetland) or when the bird is hidden in the undergrowth?

·        Does movement of the bird make a difference?


After test we can say:

·        It needs around 5s to record the coordinates

·        No difference when the bird is in an open area or undergrowth

·        If it’s moving, it takes more time to record a coordinate (after 70s it switches off)

With this knowledge, we’re calculating that overall we will have between 120-125 recordings on each bird. The aim of this project is to know exactly the origin of these pipits and where they breed.

So the recordings are:

1x recording per week 4x recording per week 5x recording per week 4x recording per week 1x recording per week
March - April
April - mid-May
mid-May - August
August - October
Obctober - ...
24 o'clock
24 o'clock half past 8
 24 o'clock  24 o'clock

--> see shedule below (photo 1)

We’ll take 5 coordinates per week during the breeding season to find out the coordinates of their breeding grounds. Since we are not sure when they start to breed we programmed the 5 weekly readings from mid May until August. The GPS will take the coordinates at 0830HRS when the birds are very active.

During the migration to their breeding place in April and then back to our wintering grounds around November, the GPS will take 4 coordinates per week. From the test we know that the GPS needs more time to take coordinates when the birds are on the move. So we programmed the GPS to take the coordinates at midnight when the birds are sleeping either during migration or in their roost in winter.

We don’t have enough time and power in the GPS to find out where the pipits spend the day during the winter, questions like: do they feed near or far from the roosting sites? We can take just some coordinates during this time but since the readings in the winter months are programmed to be taken at midnight we will only know whether they come to the same roost every night or if they visit other roosting sites in the region. Maybe we can charge the GPS again next year and see where they are feeding during the day in winter.

First capture:

We (Charel Klein, Dave Lutgen and Raoul Mettenhoven) opened the first nets Friday the 27th February. Since we have been observing the roost for some years now we know which areas they prefer to sleep and we know where water pipits concentrate in the roost. For the first ringing session (we needed to refresh the method of putting GPS on) we decided to open an area where birds don't concentrate. We opened the nets at 5 pm and closed at 7 pm (control at 6). There was football game in the nearby football ground and it was rainy.

We caught:

·        6 waterpipits

o       4 control from 2013 & 2014

o       2 new birds

·        3 Wrens (Troglodytes troglodytes)

·        1 Reed bunting (Emberiza schoeniclus)

We put the GPS the same way as we did on Reed Warblers and use the same harness material.

Before we put the GPS on we check :

·        Net number

·        Fat & muscle

·        Age & sexe (= comparison with photos from the years before and Lucas Jenni book)

·        Winglength & length of 3rd primary feather

·        Weight & other remarks

Second capture:

With Charel Klein, Max Steinmetz and Philip Birget we opened Saturday the 28th February different nets at Schlammwiss site from the first time. We didn’t catch that much because of a football game in the nearby football ground and over falling balls in the reeds. To the end of the day we caught 3 reed buntings, 1 yellowhammer and 1 waterpipit (which we tagged the day before). We checked if everything is okay with the bird and let it free again.

Back to the sleepingplace:

After each session we close the nets after 7 pm and after the ringing and processing of the pipits, which sometimes takes hours, we always return the water pipits back to the site where they were caught. So they can get out of the roost with the other birds the next morning, this will hopefully decrease the stress and disturbance on the birds after the process of GPS tagging the previous night.

Spotted Nutcracker

As one of the most mystical birds, the spotted nutcracker spends all of his time in coniferous forests. The main nutrition source are cones. It's fascinating to which degree, evolution enabled this species to occupy an ecological niche that has hardly any biodiversity.


Apart from the spotted nutcracker, we were able to observe some red crossbills (Loxia curvirostra).

Report of the month - January

As usual , January was a quiet month for bird ringing. In total 8 ringing sessions were carried but much more technical visits and work were done. In the beginning of the month , an inventory of all the ringing material and rings was carried out. Still, with 8 sessions only, 448 birds were ringed and recaptured mostly in the last two weeks of the month when the weather turned cold and chilly.


This is a good number for January!

Most of the birds are caught near the bird feeders at this time of the year or at the water's edge with special traps. Interesting captures were a Sparrowhawk (Accipiter nisus) on the 17th, 1 Chiffchaff (Phy. collibita) and 2 wintering Water Rails (Rallus aquaticus) thanks to the effort made to check the winter population of Rails in our reserve . To note also were 6 Long tailed Tits (Aegithalos caudatus) of the nominate ssp, 3 Mallards (Anas plathy.), 17 Yellowhammers (Emb. citrinella) and 1 Magpie (Pica pica).

We had also some remarkable recaptures of 3 different Nuthatches (Sitta europea) and 3 Middle Spotted Woodpeckers (Dendrocopus medius) that are visiting the feeders on a regular basis, the latter is quite worthy of note since it is not that common to have 3 Medium Spotted Woodpecker visiting our feeders on the habitats of our reserve.

It was a good opportunity for the team to learn more about this secretive species of woodpecker. Schlammwiss Reserve is not only about bird ringing but our team also keeps a good lookout on the birds around.


The big task for this month was observing the water pipits (Anth. spinoletta) roost in preparation for the GPS project that will take place in the coming months, more info on this project on our website, click here

There was up to 6 Teals around (Anas crecca) 2-3 Water Rails (Rallus aquaticus) wintering in Sias area, regular flocks of Siskins (Carduelis spinus) visiting the Birch trees during the day and 2 Black headed Gulls (Lar. ridibundus) were also observed in the first days. Cormorants number increased in the reserve as the water starts to freeze in lakes and waterways around the reserve but fortunately the water does not freeze in the water treatment ponds so it's a good fishing place for Cormorants.

A white wagtail (Mot. alba) and at least 2 Grey Wagtails (Mot. cinerea) are passing the winter in the resrerve too. Up to 6 Great White Egrets (Ardea alba) were obsreved flying over the reserve , some roost in the reserve too.

We also observed an increase in the numbers of Fieldfares (Turd. pilaris) and Blackbirds (Turd. merula) at the last week of the month probably due to the recent cold snap that pushed more birds from the North to move South.


The nestboxes have been cleaned on Sunday morning, the 18th with Raoul, Tiago and Cédric. We got a surprise in one of them being populated by a mice family.


Thanks to the team for the effort they make even in this cold weather to work, ring and observe birds in our reserve.

Weekend 24.& 25. january

We started today with a cormorant in the net!


Unfortunately he found the way out before one of our birdringers could catch him...


Anyway we had a good day! Just less birds than yesterday..

We recaptured a Grey wagtail (Motacilla cinerea) (adult male) from 2013 !!

and a Chiffchaff (Phylloscopus collybita) from november 2014. The bird stayed over the winter.

Furthermore one White waigtail (Motacilla alba) (with a ring from us! ), two stonechats - male & female - (Saxicola rubicola) two red kites, about 30 siskins and some water rails have been see.


In Mensdorf (2 km away in a natura2000 area) we checked about a second sleeping place of waterpipits (Anthus spinoletta). We counted 30 birds and managed to photograph one with a ring!

The waterpipits come every year to our natural reserve and stay over the winter. This year we try to give them a gps- transmitter to find out from where they are (where they breed?). Further information will follow...

Yesterday, we counted about 89 waterpipits coming to their usual sleeping place

3 000 000 Bramblings!

Around 3 million Bramblings (Fringilla montifringilla) found a roosting place in Hasel/Schopfheim in Germany near Switzerland. These birds come from the north and take the opportunity to feed on beechnuts. Because of the hard winter in the high mountains of Switzerland it's impossible to pass this way. This is why so many birds are roosting at one place.
To find some food, the birds are going in the forest around and eat around 80t of beechnuts each day..

It's a big show when thousands of birds are coming from every side to a few hectare large forest. Common buzzard (Buteo buteo), Goshawk (Accipiter gentilis),  Sparrowhawk (Accipiter nisus) and Peregrine falcon (Falco peregrinus) are common guests every evening and try to feed on some of the Bramblings.

3 Members of the schlammwissteam (Dave, Max and Charel) and  Christian Stange (german ornithologist) went twice to have a look at this very special show

On Saturday and Sunday 17th and 18th of January,

Two membes of the Ringingstation 'Schlammwiss' (Dave and Charel) went to Radolfzell (Germany), in order to participate at the Bird ringing license course of the ‘Vogelwarte Radorfzell’. The course explains the judicial situation, the banding material and the handling of birds. Furthermore, they tested our knowledge on padded birds and we made a visit of the attached Max-Planck Institute.


They did this course in order to support Bird ringing projects in Germany and maybe to get started with their own projects.

Ringing of rose-ringed parakeets in Bonn

On January the 10th, the Schlammwiss-Team comprising Jim, Dave, Cédric, Nicole and Niklas visited another bird-ringing team in Bonn, Germany.


The local team around the ornithologists Esther Koch, Victor Corman and Sönke Twietmeyer as well as many other helping hands met at a roosting place near the river Rhine to ring rose-ringed parakeets (Psittacula krameri). Esther Koch has already examined the influence of the rose-ringed parakeets on cave breeders in Bonn in her diploma thesis.


With a current population size of approximately 1.300 individuals in Bonn, she found that the parakeets do not pose a significant threat to native cave breeders.


The parakeet’s native range is India and Africa but the wild populations in Bonn, and also those in Cologne and Brussels, are descendants from individuals which succeeded in escaping from private keepers and zoos.


In order to learn more about this bright green colored bird concerning age, sex and their life history in cities of temperate zones, the team of experts decided to continue the study on the rose-ringed parakeet. They are usually being captured with standard mist-nets for song birds. For parakeets, these nets are more effective than nets with wider meshes because this way the parakeets lie loosely in the pockets and can be removed easily by experienced bird-ringers. The disadvantage is, that many of those caught turn around in the net pocket and escape.


The whole team which included more than 20 bird ringers, scientists and helpers placed two nets near a group of plane trees not far away from the river Rhine. Plane trees are the favourite roosting trees of that species. As soon as the night fell, swarms of starlings, carrion crows and jackdaws settled down on the branches of the surrounding trees. Shortly afterwards, small groups of parakeets gathered on trees along the banks of the Rhine and places nearby. As it got darker, more parakeets flew in. Typical for their behavior before roosting time, groups of parakeets rush almost on ground level at high speed towards the trees and then rising again onto the branches where they loudly inform their conspecifics of their presence.


That is the moment in which the parakeets were caught. The team split up into small groups to remove the birds from the nets to ring and examine them. Others stayed hidden but close enough to the nets to observe further fly-ins. Regarding the strong force of their beak that even allows them to crack nuts, we took care of ringing them with rings made out of steel. Simple aluminium would rapidly fall victim to the beak’s destructive force. It became clear very soon that is impossible to ring parakeets without using protective handgloves. Indeed, their strong beak can cause painfull injuries. Additionally, it is hard to put the ring on the bird’s leg because it is just a tiny bit longer than the ring itself. After the ringing, the wing length and the length of the middle pair of tail feathers were measured. That method showed that males have longer tail feathers than females. Then the weight of the birds was taken and their wing was spread on a black background to take a photo. Lots of wing photos will allow to see differences in feather characteristics for age determination.


To really find out whether a non-male couloured bird is a female or a juvenile, the scientists took a cloacal swab of each bird for a molecular examination in a laboratory. Moreover, that same sample gives information about the bird’s health. The exact age of a rose-ringed parakeet cannot be determined by pure vision. We know however that adult males only get a rose coloured ring around their neck during their third calendar year.


Concerning age determination, there is another unusual characteristic whose occurrence depends on the season of catching and the past weather conditions. Partially, the rose-ringed parakeets showed signs of frost bite on the underside of their feet. Claws and toes can fall of in case of long term frost periods. Knowing that, a young parakeet hatched the year before, it can be distinguished from adults by the good condition of its feet on. If the toes are still on in January, the winter weather has been rather soft in that year.


Although the weather was windy and dark clouds and short rain showers accompanied the ringing action in the late afternoon, the team had great luck with at least six rose-ringed parakeets that made a little stop-over before they went into their roosting trees.


For the Schlammwiss team this was the first contact with this species. An exceptional experience for all of us – and probably not the last.


THANKS for the impressing insights into the handling and ringing of rose-ringed parakeets to Sönke Twietmeyer and the whole team in Bonn.

Fit by nature

We organised the first "Fit by Nature" activity the 3. January. Unfortunately we had just 2-3 hours time to work before it started to snow.

We had new 4 people who were interested to come to our station and help. But it was only time to present the station and cutting some hedges.

We say thank you to the team!

Wallcreeper in Dinant

On the 30th of December a student of Biology, who started to screen systematically the rocks along the Meuse River, spotted a Wallcreeper in Dinant. This bird of the high mountains is largely resident and its closest breeding area is in the Alps. There are some rare reports about wintering birds in the Netherlands or England but it’s very exceptional to see it so far afield. The last record in Belgium was in 1988. Ornithologists from Belgium and the neighbor countries travelled to this small Belgian city to have a look at this special guest.

Among them two Luxemburgish guys, who couldn’t resist to add this bird on their lifelist. The weather conditions were good and we have found it quite easily on the rocks near the citadel of the city center. Nevertheless, Dave and me, we were impressed by the difficulty to spot it, despite the striking flight feathers.  For about half an hour we observed the bird climbing around the mountains and flying in its butterfly style.

Jim Schmitz visited this bird on the second january with Guy Mirgain and Isabelle Zwick (from the Bridringingstation Brill).

Zeeland: Birding Trip 

From the 26th of December to the 30th of December, 8 members of the Birdringingstation went to the Netherlands, in order to do sea watching and having a look at thousands of ducks and geese. We went to Zeeland, a province located in the South-West of the Netherlands. Most of the province is composed of islands, which are located for the most part below sea level. 



On the first day we started at 7 a.m. in Luxembourg and reached the first spot at 12 o’clock. The first spot were wetlands around the Veerse Meer; this spot gave us the opportunity to see different kinds of plovers (Grey plover (Pluvialis squatarola), European golden plover (Pluvialis apricaria), Common ringed plover (Charadrius hiaticula)), the usual oystercatchers, some Common Redshank (Tringa totanus) and some Knots (Calidris canutus).

Highlight at this spot were two Red-breasted geese (Branta ruficollis), which was travelling around with a group of Brent geese (Branta bernicla). The stop of the day was the Brouwersdam, which is one of seven constructions, whose goal is to protect the Rhine–Meuse–Scheldt delta from floods and storms.

At the Brouwersdam we managed to see different kinds of divers (Red-throated diver (Gavia stellata), Black-throated loon (Gavia arctica), Horned grebe (Podiceps auritus), and Black-necked grebe (Podiceps nigricollis)), some Gulls and some Shorebirds (Purple sandpiper (Calidris maritima), Ruddy turnstone (Arenaria interpres) and Bar-tailed godwit (Limosa lapponica)).



During the night there was a snow storm, which meant that at 7.30 a.m., when we left the houses we had very bad weather conditions. On the second day, the first spot was the Brouwersdam, where we managed to see some sea ducks (Common scoter (Melanitta nigra), Common eider (Somateria mollissima), and Common goldeneye (Bucephala clangula)).

As the weather conditions were very bad at sea, we drove inland with the intention of seeing more birds in flooded marsh areas. The area which we chose is called Zierickzee; it’s a mixture of fields and flooded marsh areas. At this spot, we managed to see different duck species (Northern pintail (Anas acuta), Northern shoveller (Anas clypeata), Common teal (Anas crecca) and Eurasian widgeon (Anas penelope)), furthermore we were able to see different shorebird species (Pied avocet (Recurvirostra avosetta) and Northern lapwing (Vanellus vanellus)).

At the end of the day a highlight was a Northern harrier (Circus cyaneus) crossing our way.



The third day started with a great sunrise at temperatures of -1.5°C. As light conditions were very good, we took the opportunity to do sea watching: beneath thousands of sea ducks, we were able to observe a group of playing harbour seals (Phoca vitulina). Around 11 o’clock we headed towards the Deltapark Neeltje Jans; at this spot we tried to see the common shag (Phalacrocorax aristotelis) and a Red phalarope (Phalaropus fulicarius) but unfortunately we were unable to find these birds. Not very happy, we still continued and managed to see Redwings (Turdus iliacus) and some Eurasian rock pipits (Anthus petrosus).

With the day coming to an end we spent the last hours on the Brouwersdam, benefitting from the low tide and a very calm sea to observe roosting birds.



On the fourth day the sky was cloudy and temperatures quite low; this made us head towards field observations. This means, that we spent the day scanning different fields in order to see different goose and swan species. At the end of the day, we managed to see a Greater White-fronted Goose (Anser albifrons), a Bean Goose (Anser fabalis), a Greylag Goose (Anser anser) and a big group of Barnacle Geese (Branta leucopsis). In addition to this we saw some Water pipits (Anthus spinoletta), some Meadow pipits (Anthus pratensis) and a Common Kingfisher (Alcedo atthis).



The fifth day was the last day of our trip, but as the weather was quite good we spent some more hours on the Brouwersdam. At 11 o’clock, we met a group of Dutch birdwatchers staring at the harbour. As exchanges of information are usual in ornithology one of them came to us and told us that they were observing a Black guillemot (Cepphus grylle). This bird was very special for most of us; it’s a species which usually breeds in the north (Ireland, England and Scotland) and is hardly ever seen in the Netherlands. Furthermore, as we were able to observe the bird at a distance of 15 meters a lot of people took the opportunity to take pictures.



Finally, I’m able to say that we had a great trip, the objective of which was to observe and identify the biodiversity of birds in the Netherlands. In addition to this, we were able to transmit our knowledge to some motivated guys in our team. All in all, we were able to see 102 different species.

Birdringingactivity in Nieuwpoort / Belgium

On Tuesday 9 December 2014, me (Joseph Dunlop) and Charel Klein, left Luxembourg early in the morning to head to the Belgian coast city of Nieuwpoort to take part in a cannon netting activity aimed in catching and ringing coastal birds. The activity was organised by the Belgian Royal Institute of Natural sciences and was managed by ringer Norbert Roothaert. We arrived around midday and the team was already in place more than 20 ringers and volunteers were present. The nets were set on the beach and the circuit was in place while the wait started for the birds to come on the beach as the tide retreats. While we were waiting, we observed several hundreds of oystercatchers and Lapwings, good numbers of Dunlins, Cormorants, Turnstones and Gulls. The wait was long as we had to be sure that the tide was in the right place, firstly, so that we get the maximum birds possible and most important that it is safe for the birds.  When it was the right time , the switch was hit and the nets were shot.  73 oystercatchers were ringed, 16 recaptures. 2 more than 22 yrs old !! It was a great experience , the teamwork was excellent in making the process fast and efficient.  Routine measurements were taken on the birds and we learned a lot about ageing waders.  It was worth the long drive, it is always great to make an experience like this different from our routine of ringing passerines.

CES birdmonitoring in Mainz

Hey everybody, today we skipped one ringing activity in order to visit a meeting of Constant Effort Sites (CES) in Mainz organised by Ismega, who celebrated their 10th anniversary. They got some very interesting results and a very special pleasure was the presentation about Birdmonitoring in the 21th century presented by Franz Barlein responsible of the 'Vogelwarte Helgoland'.

Another interesting presentation has been the CES in Trier by Dr Ortwin Elle, who visits our ringingstation regulary with the students of the University of Trier.

A big thanks to the Ismega who organised the meeting and to our team Jim Schmitz,Charel Klein, Nicole Thien, Cedric Brodin and Dave Lutgen

Trainee goes abroad

Col de Bretolet

At our station we have many people working and helping on the site and by all the activitys! Young and old, birdringers and trainees! Some of the trainees work already  several years at the birdringstation.. and start now to go abroad to see other/new places, see different birds, meet new people and learn other techniques!

The story of a trainee:

My name is Charel Klein. I am student for forestmanagement and environment (minor protection of nature) at the university Freiburg im Breisgau in Germany. I started 2011 with ornithology at the birdringingstation Schlammwiss.

I visited already some little birdringingstation in France and worked together with Christian Stange in Freiburg but I decided to visite my first 'big' birdringingstation this year. I found 'Col de Bretolet' in Switzerland and wrote a mail to join them! Unfortunaley I was a bit late so I haven't got a place... but in october I got a mail to join them!!  On friday 17th I drove to Freiburg and later on to Barme from where I walked 2 hours (didn't find the correct way..) up to 1923m . This year Sarah Althaus and Marco Thoma were working for the whole season at the Col the Bretolet and have been supported by helping volunteers.


Information about Col de Bretolet:

Since 1958 the ornithological station Sempach  makes studies about  bird migration in autumn. They ring every year about 10 000 - 20 000 birds with more than 100 different species. By every controll they take the date and time for exact studies about the migration. From other measurments , size, weight, fat and muscle they analyse the physical condition of the birds.

The nets are open 24to 24 hours. The nets are on the back of a mountain in  a long line over a pass where all the birds  try to fly over. You can  hear and see many birds arriving in the valley and try to fly over the mountain. With usual mist nets and highnets (which can get change at night and dayposition) they catch  the  birds. A controle is made every hour. Everybody goes to the nets to take out  the birds . They mark the netnumber, netpocket and time (wintertime). Later on they bring the birds to the second cabin where  two motivated birdringers  wait to ring them and take  measurements.

Beside the data of birds they look also at the migration of moths and bats (which get caught in the net).



We had two cabins there. 3 bedrooms, a kitchen and a birdringingroom. The only heat place was the kitchen were we cooked all together. The shower was outside with cold water and the toilet too but you had an amazing view.... You don't need more!

When I arrived the weather was pretty good and hot! But it changed on wednesday.. It started with rain and fog and ended up with 40 cm snow... so i had everything :)



The first days we had many birds like: Erithacus rubecula, Fringilla coelebs, Fringilla montifringilla, Coccothraustes coccothraustes; later we had many tits, most of them were Cyanistes caeruleus, Periparus ater! We had a day with more than 1 000 birds and one with no birds

I took the chance to benefit from a lot of new species (for me)  and to make a photo-collection for identification.



All in all:

It was an amazing place! with very nice and interesting people! I was really happy to have  the chance to join them and a big THANKS  to Sarah and Marco!

Maybe i see them back.. next year ;)

Low migration

A low migration with only 180 new birds..

But we had one special one Cinclus cinclus!! Number 3. for the birdringingstation 'Schlammwiss'. Normally this birds are flying at fast running rivers, but now juveniles are searching for a new districts.

We also had three juveniles Lanius collurio which is very rare to have them in the same net at same time!


At the end of the day we had a screaming Picus viridis who found the way in the highnet over the little river ('Syr').

Saturday the 23 August

Saturday the 23 August started with a chilly dawn and the immediate spectacle was more than 20,000 Starlings flying out of the roost. What a sight ! The usual Hobby ( Falco Subbuteo) was doing it's usual early rounds to try to catch one of the swallows. First control of nets proved as expected very good. There was again good migration of Reed Warbler ( Acr Scirpaceus) with more than 150 ringed and the most interesting was a particularly small Reed Warbler that had the wing formula and other measurements similar to the rare Blyth's Reed Warbler, an acrocephalus that breeds in extreme North east Europe and is rare in Western Europe. We finally decided ( although still not 100% sure) that it was a small Reed Warbler.

Number of migrating Blackcaps ( Syl Atricapilla) are also slowly increasing, we ringed more than 30. Other interesting species that we caught were 1 Great Reed Warbler ( Acr Aur), 1 Savi's Warbler ( Loc Lusc) and 2 Bluethroats ( Lusc Svec). Still some Trans Saharan migrants around, 1 Nightingale ( Lusc Megar) , 5 Garden Warblers ( Syl Bor) , 5 Grasshopper warblers ( Loc Nae) and 4 Whitethroats ( Syl Comm). Another interesting morning in Schlamwiss! And again this will not be possible if we did not had a great team for this day.

We had a low number of birds this morning..

Special birds this morning were Actitis hypoleucos, Anas platyrhynchos, Jynx torquilla and 4
Alcedo atthis

We tried to make photos of the starlings which have a sleepingplace at 'Schlammwiss'. Around 10 000 - 15 000 birds come every night to the reeds, sleep there and start every morning at the same time and fly in different directions!!
A big event..!!

Report of Ringing Sunday 10/08/2014


On Sunday morning when the rain stopped and we opened the nets, the team was kept busy and on the move because with this weather situation there was huge migration of Reed Warblers (Acrocephalus scirpaceus) as expected at this time of the year . During the whole morning 350 Reed Warblers were ringed. The rain made the birds go down for cover and as a result of this the nets were full of birds most of the controls. The last first year Marsh Warblers (Acrocephalus palustris) are still on the move too, 40 were captured and with these another Acrocephalus, the Sedge Warbler (Acrocephalus schoenobaenus) was present in good numbers with total of 15 ringed. First two Bluethroats of the Autumn migration were ringed also today , this year we started with two female specimens one adult and one juvenile. Other trans saharan migrants have been in good numbers too , Garden warbler (sylvia borin) 16 ringed , Whitethroat (Sylvia Communis) 6, the first Whinchat ( Saxicola Rubetra) was ringed. 3 Nightingales (Luscinia megarhynchos) , 3 Willow Warbler ( Phylloscopus Trochilus) and 1 juv. Red-Backed Shrike ( Lanius Collurio) added to this variety of species. Special attention was given both from the ringers and the paparazzi to 2 Firecrests ( regulus Ignicapillatus) as they are not common to catch in the reserve and they are so small that need special handling. Highlight of the day was a Savi's Warbler ( Locustella Luscinoides ) that was ringed and the third one caught for this season. A Common Sandpiper ( Actitis Hypoleucos) was also ringed and caught in it's typical habitat , the bridges over the ponds . Big thanks to all the team that was kept busy the whole morning. In total 489 birds were captured, great morning !!

Ringing week-end 12.07-13.07.2014

This week- end was quite international, we were 6 nationalities. Two ringer`s from France. three exchange students from the university of Trier ( Germany) and our local team. Apart from the local breeding birds we caught the first migrating birds among them have been 3 Sedge Warblers ( Acrocephalus schoenobaenus), 1 Green Sandpiper ( Tringa ochropus), 2 Common Sanpipers ( Actitis hypoleucos), 2 Spotted Crakes ( Porzana porzana) and a few migrating Marsh Warblers ( Acrocephalus palustris). Another intersting catch is an adult Water rail ( Rallus aquaticus)( ringed last year) moulting the primaries and secondaries which allows us to say it`s a breeding bird. All in all we ringed 344 birds, 209 first captures, 123 recaptures and 12 control captures.
