Wildlife officials and members of the public have seen higher than usual numbers of stranded or dead marine mammals and birds along southern California beaches in recent weeks. The U.S. Fish and Wildlife Service, National Oceanic and Atmospheric Administration, California Department of Fish and Wildlife, and the USGS National Wildlife Health Center are working together to document the size and scope of affected wildlife and mortalities. Stranding reports have included loons, grebes, cormorants, California brown pelicans, and California sea lions. Many loons are currently migrating through the Santa Barbara Channel on their spring migration northward.
