Birding in California
California boasts the longest bird list of any U.S. state, with over 670 species recorded across deserts, mountains, coastline, and fertile valleys.
Overview
No other state matches California's birding diversity. From the fog-draped redwood forests of the north coast to the scorching desert oases of the Salton Sea, from the high Sierra Nevada to the teeming pelagic waters off Monterey Bay, California offers an unrivaled range of habitats and species. The state's position on the Pacific Flyway funnels millions of migrants through each year, while its geographic isolation and varied climates support a wealth of resident specialties. The Central Valley is one of the most important wintering grounds for waterfowl on the continent, hosting millions of geese, ducks, and Sandhill Cranes each winter. Southern California's coastal sage scrub shelters the endangered California Gnatcatcher, while the Channel Islands support unique subspecies and nesting seabird colonies. Whether you are chasing a California Condor soaring over Big Sur, scanning for Elegant Terns at Bolsa Chica, or sorting through sparrow flocks in the high desert, California rewards birders with something extraordinary in every season.
Seasonal Birding Guide
Neotropical migrants pour through desert oases in late April. Shorebird numbers peak along the coast and in the Central Valley. Mountain meadows come alive with breeding Lazuli Buntings and Western Tanagers. Spring pelagic trips off Monterey produce shearwaters, storm-petrels, and the occasional albatross.
Breeding season is in full swing across all elevations. Mountain Quail call from Sierra slopes, while Tricolored Blackbirds nest in Central Valley marshes. Summer is prime time for pelagic birding, with Ashy and Black Storm-Petrels, Scripps's Murrelets, and Blue Whales drawing birders offshore. Desert heat pushes most birding to the coast and mountains.
Fall migration is prolonged and spectacular. Vagrant season brings eastern and Asian rarities to coastal promontories. Hawk migration peaks along the coast and inland ridges. The Salton Sea hosts massive gatherings of shorebirds and terns, while the first winter waterfowl arrive in the Central Valley by October.
California's mild winters make it a refuge for millions of birds. The Central Valley hosts vast flocks of Snow Geese, Ross's Geese, and Sandhill Cranes. Coastal estuaries fill with loons, grebes, and sea ducks. Mountain finches and rosy-finches descend to accessible elevations, and the Channel Islands offer winter seabird viewing.
