Abstract Background The long-tailed duck (Clangula hyemalis) was categorized as ´Vulnerable` by the IUCN after a study revealed a rapid wintering population decline of 65% between 1992–1993 and 2007–2009 in the Baltic Sea. As knowledge about the

Arctic birds migrating southwards face a multitude of challenges such as habitat loss, pollution, overexploitation of food resources and climate change impacts. Long-tailed Duck winter populations in the Baltic Sea have declined in recent decades. Ho

Land use intensification caused severe population declines in many grassland bird species. For the Corncrake, a multi-brooded, ground-breeding rail that inhabits mostly agricultural grassland, more frequent mowing at earlier dates is a threat to nest

The Corncrake Crex crex breeds mainly in managed grasslands in Europe. Agri-environment schemes (AES) were introduced in many European countries to protect broods from earlier and more frequent mowing. In order to assess the efficacy of these AES on

Red-necked Grebe (RNG) breeding numbers have been declining in parts of Europe for more than 10 years. We have examined population trends and estimated, for the first time, survival rates of RNGs in a population in eastern Poland in order to explore

SummaryCorncrakes Crex crex mainly breed in grassland, where they are threatened by mowing. Conservation requires delayed mowing or modified mowing methods. In large fields, it has been suggested that leaving strips of uncut grass may reduce mortalit

After losing their nests or broods due to mowing of grassland, ground-breeding birds may re-nest or disperse from the previous home-range. Breeding corncrakes are frequently affected by mowing of grasslands and often disperse over long distances afte
