Elephant Seal Relaxing

Seabirds and mammals take advantage of the remote rocky islands off the coast of California.  Farallon National Wildlife Refuge supports the largest seabird nesting colony in the contiguous United States.  More than 400 species of birds have been recorded on the refuge, and  five species of marine mammals pup or haul out on the refuge.
