  • Research Gate Profile

  • Research Interests:

    I am an Ornithologist and Behavioural Ecologist with a great interest in bird migration. My research is focused on the spatio-temporal organisation of migration in songbirds, with a special emphasis on navigation and the timing of migratory activity. I am interested in birds’ endogenous migratory behaviour, and how they integrate a variety of cues to find the way to their migratory destinations and to time the departures for their migratory flights.

    For my research I apply and combine different methods to record migratory orientation and activity in captive birds, or track the individual migratory behaviour (e.g. timing and direction of departures from stopover) in free-flying birds by means of radio-telemetry.

    I am experienced in collecting and analysing data on migratory restlessness and individual birds’ migratory behaviour in the field, and took an active role in the setup and maintenance of an automated radio-telemetry network on the German island of Helgoland (first extension of the MOTUS wildlife tracking system in Europe; see more about MOTUS here).

    I would be happy to consider suggestions for collaboration.
