Wildlife & Habitat
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.
Twenty-five percent of breeding seabird populations in California occur on the Farallon islands. Thirteen species nest on the islands including Leach's Storm-petrel; Ashy Storm-petrel; Fork-tailed Storm-petrel; Double-crested Cormorant; Brandt's Cormorant; Pelagic Cormorant; Black Oystercatcher; Western Gull; Common Murre; Pigeon Guillemot; Cassin's Auklet; Rhinocerous Auklet; and Tufted Puffin. Point Blue Conservation Science (formerly known as PRBO Conservation Science) has been monitoring these seabird populations since 1971.Learn More
