Effect 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 bi...
