It is the middle of winter along the northern Greek border. In the Evros Delta, thousands of water birds have taken over every last inch of the wetland. Among them are the only 30 remaining pairs of lesser white-fronted geese, claiming their own little patch along with hunters, birdwatchers and poachers. The documentary Feathering Heights invites us to follow their journey of coexistence between man and birds, starting in the Arctic Circle and extending all the way to the Mediterranean Sea, in the wetlands of the Evros Delta and Lake Kerkini in Northern Greece.
