Because migration is highly time‐constrained and migration timing varies among individuals, the responses of migrants to food shortage at a refuelling site could differ between individuals that arrive early and late at the site. To test this hypothesis, we compared the stopover decision, in terms of occurrence and length of stay (LOS), of radiotagged Great Knots Calidris tenuirostris before (2012)...
The simultaneous effects of habitat traits and interspecific interactions determine the occurrence and habitat use of wildlife populations. However, little research has been devoted to examining spatial co‐occurrence among closely related species while considering the effect of habitat variation and imperfect detectability of species in the field. In this study, we focused on migratory and resident...
The identification of the onset of prenuptial migration is fundamental in defining the closing date of the hunting season in compliance with the EU Birds Directive. Here, we describe the process and country‐by‐country approach currently followed by the European Commission to define the onset of prenuptial migration for each huntable bird species and Member State, highlighting the resulting discrepancies...
