There is currently little evidence that wider countryside agri-environment scheme (AES) management has led to population-level benefits for farmland birds and it is timely to consider why this might be the case, so that AES options can be improv[...]

The ideal free distribution (IFD) model predicts that a density-dependent mechanism operates to regulate habitat selection and reproductive performance. We studied a Little Grebe Tachybaptus ruficollis population, which breeds on irrigation pond[...]

The UK has sovereignty over 16 Overseas Territories, which hold some of the world's great seabird colonies and collectively support more endemic and globally threatened bird species than the whole of mainland Europe. Invasive alien mammalian pre[...]

A species' susceptibility to environmental change might be predicted by its ecological and life-history traits. However, the effects of such traits on long-term bird population trends have not yet been assessed using a comprehensive set of expla[...]

Other than during periods of migration, animal movement tends to be poorly described, despite the potential importance of such movements, which may prove crucial for surviving periods of bad weather and low food availability. We analysed within-[...]
