BACKGROUND
The common scoter (Melanitta nigra ) is a marine diving duck which breeds in Scandinavia and Western Siberia, which migrates each fall to join his winter range that extends Baltic Sea to Spain. This species is a fairly common winter visitor on the French coast with about 30,000 people every winter. But like other marine Anatidae, censuses carried out each year have shown a significant decline and continuing population numbers wintering in France. Meanwhile, the European breeding populations of these species are stable, although hypotheses have been advanced to explain this decline on our shores, they have never been verified. Indeed, it is conjectured an amendment to the winter range. Moreover, the counts of wintering birds are particularly difficult because of their remoteness from the coast, and evaluation fluctuations in numbers from coastal sites to monitor the active migration (SEAWATCH) seem to be a good way to assess changes in abundance and phenology of the black scoter in particular. ABOUT
The internship project revolves around two questions:
(1) Quantify changes in phenology transition and fluctuations of population numbers of Black Scoters in France on the monitoring sites the active migration of the Channel coast (Cap de la Hague, Cap Gris Nez, dike Clipon ...).
(2) Assess the importance of climate change on changes / trends detected. SKILLS REQUIRED
- Basic knowledge of statistics and data analysis
- Sensitivity naturalist
