Acoustic information as a distant cue for habitat recognition by nocturnally migrating passerines during landfall (2008)
Journal Article

During migration, birds must fly over suboptimal habitats differing from those selected during breeding and wintering. Nocturnally migrating passerines need to assess the suitability of potential stopover habitats during landfall. Before actual landf...

A Long-Distance Avian Migrant Compensates for Longitudinal Displacement during Spring Migration (2008)
Journal Article

In order to perform true bicoordinate navigation, migratory birds need to be able to determine geographic latitude and longitude. The determination of latitude is relatively easy from either stellar or magnetic cues 1, 2, 3, but the determination of...

To what extent do environmental factors affect the long-distance nocturnal post-fledging movements of the Reed Warbler? (2008)
Journal Article

We studied the effects of weather and the lunar cycle on long-distance nocturnal pre-migratory flights of Reed Warblers (Acrocephalus scirpaceus). Noturnal tape luring was used to capture the birds, and the study was carried out in a habitat atypical...

Visual but not trigeminal mediation of magnetic compass information in a migratory bird (2009)
Journal Article

Magnetic compass information has a key role in bird orientation1,2,3, but the physiological mechanisms enabling birds to sense the Earth’s magnetic field remain one of the unresolved mysteries in biology2,4. Two biophysical mechanisms have become est... Read More about Visual but not trigeminal mediation of magnetic compass information in a migratory bird.

A Double-Clock or Jetlag Mechanism is Unlikely to be Involved in Detection of East–West Displacements in a Long-Distance Avian Migrant (2010)
Journal Article

Migratory birds are known to be able to navigate—to determine their position on the globe and the direction toward their distant goal—even if they cannot perceive any information emanating from the goal. One hypothesis, that of true bicoordinate navi...
