California is one of the best birding states in the country, with an incredible mix of coastal wetlands, inland valleys, mountain forests, desert oases, and urban parks. The combination of Pacific Coast, Central Valley, Sierra Nevada, Mojave Desert, and dozens of distinct habitat zones in between gives the state one of the highest bird species totals in the contiguous U.S. More than 690 bird species appear on California’s official state checklist — one reason the state is considered one of the premier birding destinations in North America.
These California birding resources will help you find the state’s best regions, hotspots, organizations, and beginner-friendly tools. That range of habitat also means that what you’ll see in a morning of birding in Point Reyes looks almost nothing like what you’d find at the Salton Sea or in the eastern Sierra. This guide is organized by region to help you know where to go for what you want to see.
If your interest is specifically in backyard birding, the California Backyard Birds guide covers feeder setup, common species, and what to expect by season. For the California Quail — the state’s official bird — see the California State Bird guide.

Top Birding Regions in California
Northern California Coast
The Northern California coast — from the Golden Gate north to the Oregon border — offers some of the most productive shorebird, seabird, and raptor watching in the western U.S. Point Reyes National Seashore alone has recorded over 490 species, making it one of the most bird-rich single sites anywhere in North America. Bolinas Lagoon, Bodega Bay, and Humboldt Bay round out a coastline that draws serious birders from across the country.
Key species: Common Murre, Black Oystercatcher, Snowy Plover, Tufted Puffin (offshore), Black-crowned Night-Heron, Marbled Murrelet (forest edge near coast)
San Francisco Bay Area
The Bay itself is one of the most important shorebird staging areas on the Pacific Flyway. The Don Edwards San Francisco Bay National Wildlife Refuge, Coyote Creek, and Palo Alto Baylands collectively host hundreds of thousands of shorebirds and waterfowl during migration. The East Bay hills offer a different mix — including wintering songbirds, raptors, and the chance at rare species following Pacific storm systems.
Key species: Western Sandpiper, Dunlin, Long-billed Curlew, Greater and Lesser Scaup, Peregrine Falcon, Anna’s Hummingbird (year-round), White-crowned Sparrow (winter)
Central Valley
The agricultural landscape of the Central Valley supports remarkable concentrations of waterbirds, raptors, and wintering sparrows. The Sacramento and San Joaquin Valleys host millions of migrating and wintering birds annually, and the managed wetlands of the Sacramento National Wildlife Refuge complex and Merced National Wildlife Refuge are among the most spectacular birding destinations in the state.
Key species: Sandhill Crane (winter), Ross’s Goose, Snow Goose, White-faced Ibis, Tricolored Blackbird, Greater White-fronted Goose, Short-eared Owl (winter fields)
Central California Coast and Monterey Bay
Monterey Bay is world-renowned for pelagic birding — boat trips from Moss Landing regularly encounter Black-footed Albatross, Sooty Shearwater, and rare Pacific species that never come to shore. Elkhorn Slough offers some of the best accessible shorebird and waterbird watching in the state. Morro Bay and Point Sal round out a productive coastal stretch.
Key species: Black-footed Albatross, Sooty and Pink-footed Shearwater, Long-billed Curlew, Whimbrel, Snowy Plover, Brandt’s Cormorant
Sierra Nevada
California’s mountains host a distinct suite of species unavailable at lower elevations: Mountain Quail, Sooty Grouse, White-headed Woodpecker, Mountain Chickadee, Clark’s Nutcracker, American Dipper (along streams), and the spectacular Rosy-Finches in winter. Yosemite Valley is heavily visited but productive; the eastern Sierra — Mono Lake, Owens Valley, and the June Lake Loop — offers extraordinary diversity with lighter foot traffic.
Key species: Mountain Quail, Cassin’s Finch, White-headed Woodpecker, American Three-toed Woodpecker, Clark’s Nutcracker, Pine Grosbeak, Rosy-Finch (winter)
Southern California Coast and Inland
Los Angeles, Orange, and San Diego counties are among California’s most species-rich birding areas, driven by the intersection of coastal, chaparral, and desert habitats within short driving distance. The Salton Sea — a unique inland saline lake in the desert southeast — is one of the state’s most important birding destinations and a regular site for rare and vagrant species.
Key species: California Gnatcatcher (coastal sage scrub), Least Bell’s Vireo, Yellow-footed Gull (Salton Sea), Burrowing Owl, Costa’s Hummingbird, Lawrence’s Goldfinch
Mojave Desert and Eastern California
The desert oases of the Mojave — Deep Springs, Kelso Dunes, and the Amargosa Valley edge — concentrate migrant songbirds in spring and fall in numbers that can feel extraordinary given the landscape. Owens Valley offers a great mix of sagebrush species, including Sage Thrasher, Sagebrush Sparrow, and the occasional Long-eared Owl.
Key species: Phainopepla, Verdin, Crissal Thrasher, LeConte’s Thrasher, Bendire’s Thrasher, Black-throated Sparrow

Local Birding Clubs
Los Angeles Birders (LAB) is an all-volunteer nonprofit birding organization serving the greater Los Angeles area and broader Southern California birding community. Formed in 2020, LAB focuses on helping birders build real field skills through webinars, classes, field trips, community science, and bird-focused programming. It is independent of Audubon, with a different but complementary mission: education, field experience, and helping people become better birders. LAB is especially useful for beginners and improving birders because its programs are built around learning in the field, asking questions, and connecting with experienced local observers. The organization also supports young birders through LAB-S, its student program for youth and young adults who want to learn birds, make birding friends, and participate in field trips and science-focused activities.
Central Valley Bird Club (CVBC) is a regional birding organization dedicated to the enjoyment, study, and conservation of birds in California’s Central Valley. Established in 1997, the club helps connect birders across one of California’s most important inland birding regions, where wetlands, rivers, agricultural lands, grasslands, and wildlife refuges support an impressive mix of resident birds, migrants, waterfowl, shorebirds, and raptors. For birders, CVBC is especially useful because it combines local expertise with education, events, publications, conservation work, and support for research. The club is also tied to the Central Valley Birding Symposium, making it a strong resource for anyone who wants to go deeper into Central Valley birding, learn from experienced observers, and better understand the region’s seasonal bird movement and habitat conservation needs.
San Diego Field Ornithologists (SDFO) is a nonprofit birding organization focused on advancing field ornithology in San Diego County through educational programs, bird records, publications, and local birding resources. For birders, SDFO is especially useful because it supports one of California’s richest county-level birding communities, with tools for tracking rare birds, exploring San Diego birding sites, and understanding the county’s impressive bird diversity. The group holds monthly meetings with presentations by recognized experts and maintains resources such as the San Diego County avian records database, rare bird information, birding site guides, and county species information. It is a strong resource for birders who want to move beyond casual outings and learn more about identification, local records, rarities, and the seasonal patterns that make San Diego one of Southern California’s standout birding regions.
eBird & Birding Apps for California
eBird (Cornell Lab of Ornithology) The essential tool for California birding. Search any location to see recent sightings, explore hotspot species lists, and contribute your own observations. The California eBird dataset is among the most robust of any state. Use the eBird hotspot map before visiting any new site to see what’s been reported in the last 30 days.
Merlin Bird ID (Cornell Lab) Download the California bird pack before your trip so Merlin can help with the species you’re most likely to encounter. The Sound ID feature is particularly useful — hold the phone up in a new habitat and it will list what it hears in real time.
iNaturalist Broader than birds but increasingly useful for documenting rare sightings and connecting with local naturalists across California.
California Bird Records Committee Maintains the official California state checklist and evaluates records of rare species. Useful for understanding which rarities have been verified and where they’ve been found.
Best Times to Go Birding in California
California birding is productive year-round, but the timing shifts what you’ll find dramatically.
Spring Migration (April–May) is the most dynamic period for songbirds. Warblers, flycatchers, tanagers, and orioles move through in waves. Vagrant species from eastern North America turn up along the coast with some regularity. Sierra meadows and mountain habitats open up as snow retreats and breeding birds arrive.
Summer (June–July) is best for breeding species — Mountain Quail, White-headed Woodpecker, and Sierra specialties are most reliably found during this window. Pelagic birding off Monterey peaks in summer with the largest diversity of shearwaters, storm-petrels, and alcids.
Fall Migration (August–November) brings the most variety for experienced birders — shorebird diversity peaks in August and September, vagrant songbirds reach coastal areas in September and October, and winter visitors begin arriving in October. Point Reyes during October is genuinely extraordinary for vagrant diversity.
Winter (December–March) is when the Central Valley and coastal wetlands fill with waterfowl and shorebirds. The Salton Sea in winter holds enormous numbers of Eared Grebes. Sierra roadsides occasionally produce Rosy-Finch irruptions in cold years. Throughout the state, sparrow flocks in brush and hedgerows are at their most diverse and numerous.
Tips for Birding California’s Regions
For coastal sites: Arrive at low tide for shorebirds. Most productive shorebird sites are best 1–2 hours before and after the low. A spotting scope helps significantly at open mudflat sites like Bolinas Lagoon and Elkhorn Slough.
For the Central Valley: Morning is far better than afternoon due to heat shimmer over agricultural fields. The managed wetland units at Sacramento NWR have limited hours during some hunting seasons — check ahead.
For mountain birding: High elevation sites in the Sierra Nevada may not be accessible until late May or June due to snow. Check CalTrans road conditions before driving mountain passes. Dawn to noon is the most productive window before afternoon thunderstorms build.
For desert sites: Spring and fall are the practical windows. Summer desert birding is possible but physically demanding — plan for early starts, carry significantly more water than you think you’ll need, and be flexible about cutting trips short in heat.
General: Check eBird before any California birding trip. The recent sightings data — particularly at named hotspots — will show you exactly what’s been seen in the last 30 days at any location. It’s the single most useful pre-trip preparation tool available.
Beginner Birding Checklist for California
If you’re new to birding and planning your first California outing, a few simple habits make a real difference.
Check recent eBird sightings for your target location before you leave — what’s been reported in the last two weeks tells you more than any seasonal guide. Bring binoculars and arrive early; bird activity peaks in the first two hours after sunrise across nearly every habitat in the state. Match your destination to the season rather than just picking a place on a map — a Central Valley wetland in December and a Sierra meadow in July are completely different experiences worth planning around. Dress in layers, especially on the coast, where morning fog can give way to midday sun. And if you’re unsure where to start, joining a guided walk through a local chapter is one of the fastest ways to learn California birds quickly from people who already know them. If you’d rather begin at home, the Simple Backyard Bird Setup guide is the easiest way to get your first consistent bird activity going.
Start in Your Own Backyard
Not every birding experience requires a trip. For many California residents, the backyard — or a balcony, a patio, or a neighborhood park — is the first and most reliable place to start building bird recognition skills.
California yards support a genuinely interesting mix of species depending on region. Coastal yards regularly see Anna’s Hummingbirds, California Scrub-Jays, Lesser Goldfinches, and California Towhees. Foothill yards add Acorn Woodpeckers, Steller’s Jays, and Oak Titmice. Even a modest setup in a suburban yard can attract eight to twelve species consistently with the right feeder, seed, and water combination.
Starting at home has a practical advantage that field birding doesn’t: the birds return to the same spot every day. That repetition is how identification actually sticks — not from a single glance at a park, but from watching the same House Finch at the same feeder twenty times until every field mark is familiar. The California Backyard Birds guide covers which species to expect by region and how to set up a yard that attracts them.
For the practical setup side, Best Bird Feeders and Best Bird Seed cover what actually works for California’s most common backyard species. If you want a single guided starting point, the Simple Backyard Bird Setup walks through the whole thing in one place.

Frequently Asked Questions
What is the best place to go birding in California?
California has many excellent birding regions, but Point Reyes, Monterey Bay, the Central Valley refuges, Mono Lake, and the Salton Sea are among the most productive and well-documented destinations. Each offers something different — Point Reyes for coastal and vagrant species, Monterey Bay for pelagic birding, the Central Valley for waterfowl and cranes in winter, Mono Lake for shorebirds in fall, and the Salton Sea for desert and rare species year-round. Your best starting point depends on where you are in the state and what time of year you’re going.
When is the best time to go birding in California?
California is productive year-round, which is one of its strengths as a birding destination. Spring and fall migration (April–May and August–November) offer the greatest species variety, especially along the coast. Winter is excellent for waterfowl and shorebirds in the Central Valley and at coastal wetlands. Summer is the right window for mountain and breeding birds in the Sierra Nevada. If you can only go once, late April through May gives you the widest mix of resident, breeding, and migrating species.
Is California good for beginner birders?
Yes — California has a strong network of beginner-friendly birding locations including accessible coastal wetlands, urban parks, wildlife refuges with auto-tour routes, and guided walks through local bird organizations. Sites like Elkhorn Slough, the Sacramento NWR auto tour, and Bolinas Lagoon are easy to navigate and reliably productive. Local chapters like Golden Gate Bird Alliance and San Diego Bird Alliance offer free guided walks specifically designed for people just getting started.
What app should I use for birding in California?
eBird is the best tool for pre-trip planning — search any hotspot to see what’s been reported recently before you go. Merlin Bird ID is the most useful app in the field for identifying birds by sound or photo. Most experienced California birders use both: eBird to know what to expect, Merlin to figure out what you’re actually looking at.
