The most visible wildlife in Golden Gate are definitely the birds. You will see them rustling in the bushes near a path, soaring overhead, or floating across a marsh. An astonishing number of avian species live in or migrate through Golden Gate. A variety of habitats ranging from open water and protected bays, to rocky and sandy shorelines, to tidal marshes, coastal scrub, grasslands, and forests create many different habitats that support over 250 different birds. Golden Gate lies along the Pacific Flyway, and is also host to a variety of transient birds that stop over to rest and feed in their amazing journeys from equatorial regions as far south as the South American rainforests to polar regions as far north as the Canadian arctic. This combination of factors makes Golden Gate a birder's paradise. Many organizations monitor bird activity in the park for species of concern, including the National Park Service Inventory & Monitoring Network, The Audubon Society, California Partners in Flight, the California Department of Forestry, and the Fish and Wildlife Service.
