TL;DR: In this article, the authors present the first large-scale analysis of migration patterns and migratory connectivity in the globally near-threatened European roller Coracias garrulus, and demonstrate the importance of the northern savanna zone as a stopover region and reveal the easterly spring loop and leapfrog migration of rollers from eastern populations.

TL;DR: It is suggested that future studies tracking the movements of aerial insectivorous birds should use devices designed to minimize drag, as apparent survival of geolocator birds significantly varied among sites, being much higher in northern Europe.

TL;DR: In this article, a large telemetry dataset on the globally endangered Egyptian Vulture Neophron percnopterus (94 individuals, 188 completed migratory journeys), tracked across ~70% of the species' global range, was used to analyze spatial and temporal variability of migratory movements within and among individuals and populations.

TL;DR: Gender variation in plumage colour and abundance of feather mite suggests a common hormonal-mediated mechanism regulating both traits, in agreement with the long held, neglected view that feather mites form non-parasitic associations with birds.

TL;DR: Moderate migratory connectivity is found in a passerine bird, the great reed warbler Acrocephalus arundinaceus, over its wide Western Palearctic breeding range using geolocators from Spain, Sweden, Czech Republic, Bulgaria and Turkey, with a partial overlap between individual populations.
