Townsend's storm petrel (Hydrobates socorroensis) is a species of seabird in the family Hydrobatidae. It breeds in the summer on rocks and islets[2] of Guadalupe Island off the western coast of Mexico. It ranges in the Eastern Pacific Ocean north to southern California in the United States and south to 10°N latitude. It used to be considered a subspecies of the Leach's storm petrel. It was formerly defined in the genus Oceanodroma before that genus was synonymized with Hydrobates.[3]
