Dark Bellied Brent Goose

Just imagine having only two months to lay eggs, brood them and raise the young before your food disappears under a thick layer of snow and ice. That is what dark-bellied brent geese endure every year when flying far beyond Spits Bergen to the peninsula of Taymir, on the northeastern coast of Siberia. And if it stays too cold for too long after they arrive, they won't make a nest at all and have made the long 4500 kilometer-trip for nothing. After breeding season, they return to the wadden region, to spend the winter in a place less barren than up north.
