Aim Ongoing climate changes represent a major determinant of demographic processes in many organisms worldwide. Birds, and especially long‐distance migrants, are particularly sensitive to such changes. To better understand these impacts on long‐distance migrants' breeding productivity, we tested three hypotheses focused on (i) the shape of the relationships with different climate variables, including previously rarely tested q...

The nests of secondary cavity-nesters located in tree cavities may form specific microhabitats of conservation importance due to their limited accessibility and availability. Species-specific nesting materials in nests of different secondary cavity-nesters may furthermore provide very different microhabitats for arthropods. The potential differences in arthropod communities inhabiting nests of different bird species in excavat...

Aim To investigate spatial gradients in population trends of European birds in relation to their association with farmland, dietary dependence on insects, and the intensity of agricultural practices. Location Europe. Time period 2001–2012. Major taxa studied Birds. Methods We collected population trends for 197 species in 32 European countries. For the same time period, we used agricultural variables (annual yields of five maj...
