tern migration update


Last year, we re-caught 8 arctic terns, which we had equipped with geolocators in 2012. Tim van Oosten has written a master student report on the results. This figure shows the main result from the report. Panel A is the south-bound migration, panel B is the north-bound migration. Between 3 and 25 Novembrm the terns arrived at their wintering grounds near Antarctica, Departure north happened between 3 and 24 April. On their way north the birds follow the trade winds: easterly winds on the southern hemisphere and westerly winds on the northern hemisphere.
Thomas Zaw is a new student continuing to analyse the data, while Maarten is going to a Kongsfjorden workshop between 10 and 17 March to learn more about food availability during the summer season.
