15 صفحه اولEffect of Geolocators on Migration and Subsequent Breeding Performance of a Long-Distance Passerine Migrant
Geolocators are small light-weight data loggers used to track individual migratory routes, and their use has increased exponentially in birds. However, the effects of geolocators on individual performance are still poorly known. We studied geolocator effects on a long-distance migrating passerine bird, the northern wheatear (Oenanthe oenanthe L.). We asked the general question of whether geoloc...

15 صفحه اولRepeatability of individual migration routes, wintering sites, and timing in a long‐distance migrant bird
Migratory birds are often faithful to wintering (nonbreeding) sites, and also migration timing is usually remarkably consistent, that is, highly repeatable. Spatiotemporal repeatability can be of advantage for multiple reasons, including familiarity with local resources and predators as well as avoiding the costs of finding a new place, for example, nesting grounds. However, when the environmen...
