A black bear has been caught napping in an unlikely spot: the nest of a bald eagle. Researchers came across the sleeping bear while surveying eagle nests on a military base in Alaska. 

Black bears (Ursus americanus) are known to occasionally take advantage of eagles' architectural work — and these invasions spell trouble for the birds and their young, according to the U.S. Fish and Wildlife Service (FWS).
