Seasonal migration is a taxonomically widespread behaviour that integrates across many
traits. The European blackcap exhibits enormous variation in migration and is renowned for …

Passerine bird communities of Iberian dehesas: a review.—The Iberian dehesas are a man–
made habitat composed of scattered oaks (Quercus spp.) and extensive grass cover …

This paper shows how our knowledge of the evolution, ecology and conservation of birds
can be improved through the analysis of external morphological traits. After giving a short …

Migratory strategies of birds require complex orientation mechanisms, morphological
adaptations, and life‐history adjustments. From an evolutionary perspective, it is important to …

An analysis of the external flight apparatus of 700 blackcaps from eight different populations
(sedentary to long‐distance migrators) is presented. With increasing migration distances of …

Predictive habitat models rely on the relationship between a response variable (either
occurrence or abundance of a species) and a set of environmental predictors. Vegetation is …

Understanding how environmental variation influences the distribution of parasite diversity is
critical if we are to anticipate disease emergence risks associated with global change …

The Arctic is a highly seasonal environment with a harsh climate and extensive sea ice
cover during the winter. Consequently, most Arctic-breeding seabirds migrate south to reach …

In migratory birds, morphological adaptations for efficient migratory flight often oppose
morphological adaptations for efficient behavior during resident periods. This includes …

Contemporary phenotypic trends associated with global change are widely documented, but
whether such trends always denote trait optimization under changed conditions remains …
