We mapped migration routes of migratory songbirds to the Neotropics by using light-level
geolocators mounted on breeding purple martins (Progne subis) and wood thrushes …

The northern wheatear (Oenanthe oenanthe) is a small (approx. 25 g), insectivorous migrant

Ten geolocators (light-level data loggers) were attached to Common Terns (Sterna hirundo)
at a breeding site in the northeastern USA in 2007 and 2008; six were retrieved (five with …

The tracking of small avian migrants has only recently become possible by the use of small
light-level geolocators, allowing the reconstruction of whole migration routes, as well as …

Migratory divides are contact zones between breeding populations that use divergent
migratory routes and have been described in a variety of species. These divides are of major …

Despite clear benefits of optimal arrival time on breeding grounds, migration schedules may
vary with an individual bird's innate quality, non-breeding habitat or breeding destination …

Since 1899 ringing (or banding) remained the most important source of information about
migration routes, stopover sites and wintering grounds for birds that are too small to carry …

Migratory land birds perform extreme endurance flights when crossing ecological barriers,
such as deserts, oceans and ice-caps. When travelling over benign areas, birds are …
