Detailed Description
Migratory birds, like these common eiders in Alaska, pose additional management challenges because they occupy different habitats during breeding and non-breeding seasons, sometimes separated by vast distances. The three male birds have white heads and backs, black wings, and orange beaks, while the four females are uniformly grey.
