Report of the month



Report of the month - January

 

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 January, our members who are mostly volunteers, have spent about 325 hours working at  at the birdringing station "Schlammwiss".  This results in 282 hours ringing activities and 43 working hours at the station this month.

 

Thanks a lot for your help!

 

With this effort it was possible to capture 383 birds of 23 species (see the table left) this month at our station.

 

This number is subdivided in 183 E, 159 K and 41 W.  The total amount of individuals (E+K) is 342.  This is higher (+113) than the mean number of birds caught at the station from 2001-2020 and lower (-128) than the number of last year.

 

None bird foreign origin has been caught.

 

E:  first capture of this individual

W:  recapture of an individual which was already captured this year

K:  individuals which were ringed one or more years ago or individuals with a foreign country or station

The first graphic below shows the current situation of birds captured this year in comparison of the median number of birds captured from 2001-2020. In addition, we include a new bar chart with an more accurate time calculation. The bar chart is divided in the normal ringing activities, special ringing activities (e.g.: ringing Barn Owls, control of nest boxes,..) and time we spent at the bird ringing station for further work (e.g.: replacing of nets, clearing net lines, visits,...).

In older calculations, only a time calculation was done on the basis of the ringing data. This time calculation was retained for graphs 2 and 3 so that the results can be compared with recent years.

The number of birds captured this year and working time this year (old calculation) in comparison of the mean number of birds caught in the years 2001-2020 and the mean working time from 2018-2020 is shown in the second graph below left.

In the second graph below right you can find a comparison of this year with the last three years.

Graph 1

In the graph on the left you can see the course of the ringed species compared to the days with open nets of each month. Furthermore, the mean value of species and the open nets days from 2018-2020 are displayed. The distribution of birds ringed and working time per day are illustrated in the graph on the left. The number of birds ringed is separated in E, W and K.

The distribution of the age is shown in the pie chart below. You can find the exact amount in the table right. Birds with the age code 1 or 3 are considered as juvenile and birds with an age code of 4 or higher are registered as adults. Note that the age of birds with the code 6 or higher is (in the most cases) only possible to tell by recaptured birds (K). The age of birds with the code 2 is unknown.
