Summary

Our major themes this week are Iceland, geese and energetics. For the first time, we are analysing the fuel consumption of Brent geese and Greenland White-fronted Geese as they make one of the most challenging migrations of the animal kingdom: overcoming the mile and a half high icecap that stand between them and their summering sites in Greenland and Arctic Canada. Ospreys feed on protein-rich fish, which allows them to migrate such vast distances but how do these geese record comparable distances on a diet of just grass? Brett is in Iceland to find out.
