HG_JUVENILE - Juvenile herring gulls (Larus argentatus, Laridae) hatched and handraised in Ostend (Belgium) is a bird tracking dataset published by the Cognition, Behavior, and Ecology lab at Ghent University. It contains animal tracking data for the project/study HG_JUVENILE, using trackers developed by Interrex (http://www.interrex-tracking.com). The study has been operational since 2022. In total 60 individuals of European herring gull (Larus argentatus) have been tagged and released in the IJzermonding, Nieuwpoort (Belgium). All individuals were raised from egg by Ghent University researchers at the Wildlife Rescue Center in Ostend and completed several cognitive and behavioural tests when approximately three weeks old. The main goal of the study is to link cognitive performance in the lab to behaviour in the wild. more
