The main purpose of the Brenttags study is:
· to revisit our previous 1997 and 2001 studies of their migratory behavior and energetics - now hopefully both in spring and autumn
· to look much more into details about how the Brent Geese spend the summer in the Arctic.
· to look much more into details about how the Brent Geese spend the summer in the Arctic.
We can improve the knowledge from the previous studies because we now use PPTs with GPS accuracy (i.e. much more precise locations, and including altitude also, so we can study how they respond expected variable wind conditions along the route).
The PTTs are also with solar panels, so we hope they will maintain their batteries much longer than previously studied birds.
