Radio telemetry studies on bird migration
The main goal of this project is to study stopover behaviour and strategies of migratory songbirds, including movements on the peninsula during their stay, activity phases during the day/night, duration of stay in relation of fat reserves at capture and weather conditions. Also timing of departure in relation to weather, in comparison to strength of migration measured by ringing data and radar tracking before and at the departure will be studied as well as departure directions in relation to the species-specific migratory directions from ringing recoveries and possible influence of wind. We are also interested in knowing more about time of departure and availability of orientation cues, i.e., when during the night nocturnal migrants depart. We also study orientation mechanisms by manipulating sunrise or sunset cues relative to magnetic compass cues, enabling us to study the use, importance and hierarchy of different compass cues used by birds to determine their migratory direction.
In collaboration with Falsterbo Bird Observatory, we have initiated a radio telemetry study at Falsterbo peninsula. We installed three automated telemetry stations on the Falsterbo peninsula, allowing us to follow the movements of individual birds during their stopover, and to study their departure orientation, during both spring and autumn migration.
