Abstract: For geese preparing to fly to the Arctic, the motto is “the fatter the better.†But, why do not all geese get fat when food is abundant? For brent geese, modern-day agricultural pastures turn out to be a land of plenty, where food harvesting is quick and leaves free time. But to enter the top tier of birds that produce offspring, other aspects like a good health may be more important than a pile of food.
