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 June, the bird ringing station "Schlammwiss" caught about 983 birds of 43 species. This number is subdivided in 685 E, 226 W and 72 K. 1 bird foreign origin has been caught.
The total amount of birds for the month June is higher (+112) than the average amount of birds caught at the station from 2001-2018 and higher (+151) than the number of last year. The graphic below shows the average amount of birds for each month during the years 2001-2018 in comparison of the numbers of this years, 2018 and the working time for this and last year at the station Schlammwiss.
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

Brutvogelmonitoring im Naturschutzgebiet „Schlammwiss-Brill“ 2018
Using a standardized transect survey, the complete breeding bird assemblage was analysed inside a 75-ha large wetland area in the eastern part of Luxembourg between Uebersyren and Mensdorf. The wetland area is classified as national nature reserve ´Schlammwiss-Brill´ and is designated SPA (´Special protected area´) of the European birds’ directive. By having conducted 24 site visits from April to July 2018, 2´589 single records of 78 different bird species were collected. The total breeding population added up to 441 breeding territories of 48 bird species, including typical species found in wetlands such as reed buntings Emberiza schoeniclus (36 territories), marsh warblers Acrocephalus palustris (21 territories), reed warblers Acrocephalus scirpaceus (32 territories), common nightingales Luscinia
megarhynchos (7 territories) und grasshopper warblers Locustella naevia (6 territories). Besides a large breeding stock of rather common species, one territory of the nationa
