Quick Answer: The most commonly spotted birds in San Francisco include Anna’s Hummingbird, Brewer’s Blackbird, Peregrine Falcon, Western Gull, and White-crowned Sparrow — all year-round residents. San Francisco’s mix of ocean shoreline, bay mudflats, urban parks, and coastal scrub makes it one of the most bird-diverse cities in North America. Use the sections below to identify your bird by appearance, location, or behavior.
Spotted an unfamiliar bird in San Francisco and wondering what it is? You’re not alone. SF’s geography puts residents in daily contact with a remarkable range of species — hummingbirds at backyard flowers, falcons stooping off the Bay Bridge, egrets picking through bay mud at low tide. This guide covers the birds San Francisco residents ask about most, organized the way a curious observer actually thinks: by what the bird looks like, where you saw it, and how it was behaving.

How to Use This Guide
Start with the appearance section — it groups species by what you notice first. If you already know the habitat (waterfront, park, parking lot), skip to the location section. Behavior clues come third, and the detailed species profiles round everything out.
San Francisco’s geography does a lot of the sorting for you. The Pacific coast, bay shoreline, Golden Gate Park, the Presidio, and miles of coastal scrub create distinct microhabitats stacked right next to each other. That’s why you can see a Snowy Egret and a Peregrine Falcon on the same afternoon without leaving the city.
Identify Your San Francisco Bird by Appearance
Tiny Hovering Birds: Hummingbirds
If the bird is hovering at a flower or feeder and looks like it weighs nothing, it’s a hummingbird. In San Francisco, you’re almost certainly looking at an Anna’s Hummingbird (Calypte anna). The male’s iridescent rose-red crown and throat — a full helmet of color — is unlike anything else in the city. It can look dark or even black in flat light, then flash brilliant magenta when the angle shifts. Females are green above with a small pink throat spot.
Allen’s Hummingbird (Selasphorus sasin) is the main source of confusion. Males have a rufous (rusty-orange) back and tail, which Anna’s males never show. Allen’s arrives on territory as early as January and most have departed by July, so timing helps. When in doubt in SF, default to Anna’s — it’s resident year-round and far more numerous.
Both species run about 3.9 inches (10 cm) long — roughly the size of a ping-pong ball with a bill.
All-Black Birds: Crows, Ravens, and Brewer’s Blackbird
Three all-black birds cause constant confusion. Here’s the fastest way to sort them:
- Brewer’s Blackbird — robin-sized (9 inches/23 cm); male has a bright yellow eye and a purple-green iridescent sheen. Walks boldly on sidewalks.
- American Crow — larger (17 inches/43 cm); all black; fan-shaped tail; nasal “caw.”
- Common Raven — noticeably bigger than a crow (22–27 inches/56–69 cm); thick, curved bill; wedge-shaped tail visible in flight; deep, resonant croak.
Size and tail shape separate crows from ravens. The yellow eye separates Brewer’s Blackbird from everything else.
Large Birds of Prey: Peregrine Falcon
The Peregrine Falcon (Falco peregrinus) is the raptor you’re most likely to spot in SF. Adults are blue-gray above with bold black mustache marks (malar stripes) on a white face — the single best field mark. In flight, long pointed wings and a barrel-chested silhouette are unmistakable. Juveniles are brown above with streaked, not barred, underparts.
Peregrines are crow-sized to slightly larger (14–19 inches/36–49 cm), but they look heavier and more powerful than any crow. In a hunting dive they exceed 240 mph — nothing else in the city moves like that.
White Waterbirds: Western Gull and Snowy Egret
Western Gull (Larus occidentalis) is the default gull of the SF waterfront — large, with a dark gray back, pink legs, and a yellow bill with a red spot. Juvenile Western Gulls are mottled brown and take four years to reach adult plumage, but the large size and pink legs are consistent across ages.
Snowy Egret (Egretta thula) is all white and slender, with a black bill and vivid yellow feet that look almost comically bright against dark mud. If you see a white wading bird in the bay shallows, the yellow feet clinch the ID.
Small Songbirds: Black Phoebe and White-crowned Sparrow
Black Phoebe (Sayornis nigricans) looks like it’s wearing a tuxedo — black on the head, back, and breast; white on the belly. It perches upright near water and pumps its tail steadily, which is a giveaway even before you register the color pattern. White-crowned Sparrow (Zonotrichia leucophrys) has crisp black-and-white head stripes and a pinkish-orange bill. Both are common in parks and gardens across the city.
A good pair of binoculars makes these field marks much easier to pick out. (Nikon Monarch M5 8x42)
Where in San Francisco You’re Most Likely to Spot Each Bird
Urban Parks and Gardens: Golden Gate Park and the Presidio
Golden Gate Park’s Botanical Garden is the top hummingbird spot in the city — Anna’s Hummingbirds are there every day of the year, and Allen’s arrive in January and linger through early summer. White-crowned Sparrows work the shrubby edges and lawns throughout the park. The Presidio is reliable for Black Phoebe near its ponds and streams, and Peregrine Falcons have nested on structures there.
Waterfront and Bay Shore: Ocean Beach, Crissy Field, and the Embarcadero
Western Gulls dominate every inch of the SF waterfront — Ocean Beach, Crissy Field, Pier 39, the Ferry Building. Snowy Egrets concentrate at Crissy Field’s restored tidal marsh and along the bay’s mudflats at low tide. Fort Funston, at the southern end of Ocean Beach, is worth a visit for coastal scrub species and cliff-nesting raptors. Peregrine Falcons hunt over open water along the entire waterfront and have used the Bay Bridge as a nest site for years.
City Streets, Plazas, and Parking Lots
Brewer’s Blackbirds essentially own SF’s urban hardscape. Civic Center Plaza, Dolores Park, and any outdoor dining area will have them strutting around within arm’s reach. American Crows are common at the same locations but tend to be warier. Common Ravens are more likely near the coast and in larger open spaces like the Presidio.
Residential Neighborhoods and Backyard Gardens
Anna’s Hummingbirds follow flowering plants wherever they grow — the Sunset, the Richmond, Noe Valley, all of it. White-crowned Sparrows forage under shrubs in residential yards through fall and winter. Black Phoebes will occasionally use garden ponds or fountains as hunting perches.
Behavior Clues That Help You Name the Bird
Flight style is often the fastest clue. Hovering at a flower with wings a blur? Hummingbird. Diving nearly vertically from a great height in a controlled stoop? Peregrine Falcon. Crows and ravens soar and glide; Brewer’s Blackbirds fly in direct, shallow-flapping lines. Black Phoebes make short aerial sallies from a perch, snap up an insect, and return to the same spot.
Feeding behavior gets you to the right family faster than plumage details most of the time. Ground-walking boldly in a parking lot, picking at scraps? Brewer’s Blackbird. Standing motionless in ankle-deep water, then stabbing suddenly? Snowy Egret. Perching upright near a pond and darting out repeatedly for insects? Black Phoebe.
Calls and songs:
- Anna’s Hummingbird: Scratchy, buzzy, mechanical song; sharp chit call; males produce a loud tail-pop at the bottom of their dive display
- Peregrine Falcon: Rapid, aggressive kak-kak-kak-kak near nest sites
- American Crow: Familiar nasal caw
- Common Raven: Deep, hollow cronk or pruk — much lower-pitched than a crow
- Black Phoebe: Thin, rising pi-wee, repeated persistently
Seasonal behavior: Anna’s Hummingbird males perform a spectacular dive display from January through April — they climb 100 feet or more and plunge nearly straight down, making a sharp explosive pop with their tail feathers at the bottom. It’s one of the most dramatic things you can watch from a San Francisco backyard. Brewer’s Blackbirds form large mixed flocks in winter, sometimes hundreds of birds moving through parks together.
Attracting San Francisco Birds to Your Garden
Hummingbird Feeders
The formula is simple: 1 part plain white sugar to 4 parts water, boiled to dissolve, then cooled. No red dye, no honey, no artificial sweeteners — all can harm hummingbirds. In SF’s mild climate, clean feeders every 2–3 days in warm weather to prevent fermentation and mold. A saucer-style feeder is easier to clean than a tube feeder and works just as well. Hang it near a window where you can watch, but apply window decals to the glass to prevent strikes.
Native Plants
Native plants outperform feeders for long-term bird attraction. For hummingbirds: Salvia (sage species), Penstemon, Fuchsia, Monkeyflower (Mimulus), and Currant (Ribes) — an early bloomer that supports hummingbirds through winter. White-crowned Sparrows will forage under almost any native shrub for seeds and insects.
Ground and Platform Feeders for Sparrows
White-crowned Sparrows respond well to platform feeders or seed scattered directly on the ground. Millet and sunflower seeds are the best choices. Brewer’s Blackbirds will find any food source on their own — they don’t need encouragement.
What Not to Do
- Never use honey in hummingbird feeders — it promotes a fatal fungal infection of the tongue
- Avoid red dye — unnecessary and potentially harmful
- Don’t use rodenticides — poisoned rodents are eaten by raptors, causing secondary poisoning in Peregrine Falcons and Red-tailed Hawks
- Keep cats indoors — outdoor cats are among the leading causes of bird mortality in urban areas
- Add window decals — window strikes kill an estimated 600 million birds annually in the US; decals applied to the outside of glass cut strikes dramatically
The single most impactful thing you can do for SF’s birds isn’t buying a feeder. It’s planting native flowering plants and keeping cats inside.
What Is This Bird Spotted in San Francisco? Frequently Asked Questions
What is the most common bird in San Francisco? Brewer’s Blackbird and Western Gull are probably the two species most people encounter daily — Brewer’s on sidewalks and plazas, Western Gulls on every stretch of waterfront. Anna’s Hummingbird is the most commonly spotted bird in residential gardens.
What small green bird is hovering at my flowers in SF? Almost certainly an Anna’s Hummingbird. The male has a rose-red head and throat; the female is green above with a small pink throat spot. Allen’s Hummingbird is similar but has a rufous (rusty-orange) back and tail on the male, and is present mainly January through July.
Is that a crow or a raven I’m seeing in San Francisco? Check the tail in flight: crows have a fan-shaped tail, ravens have a wedge-shaped tail. Ravens are also noticeably larger and make a deep, resonant croak rather than a crow’s nasal caw. In dense urban areas, crows are more likely; near the coast and in the Presidio, ravens are more common.
What is the large white bird wading in the bay? If it has bright yellow feet and a black bill, it’s a Snowy Egret. If it’s much larger — standing nearly four feet tall — with a gray body and a long yellow-orange bill, it’s a Great Blue Heron. Both are common along the bay shoreline.
What bird makes a loud popping sound in my backyard in winter? That’s almost certainly a male Anna’s Hummingbird performing his dive display. He climbs high, then plunges nearly straight down and produces a sharp explosive pop with his outer tail feathers at the bottom of the dive. It’s surprisingly loud for a bird that weighs less than a nickel. The display runs from roughly January through April.
Conservation Note: The Peregrine Falcon in San Francisco
The Peregrine Falcon’s recovery is one of the most dramatic conservation stories in American history. DDT, widely used as a pesticide from the 1940s onward, caused eggshell thinning that collapsed breeding populations across North America. By the early 1970s, Peregrines had been eliminated as a breeding species east of the Mississippi and were critically reduced in the West. After DDT was banned in 1972 and intensive captive-breeding and hacking programs released thousands of birds through the 1970s and 1980s, populations rebounded. San Francisco now supports multiple nesting pairs on skyscrapers, bridges, and the towers of the Golden Gate Bridge approach — a result that would have seemed impossible fifty years ago. If you see a Peregrine stooping over the Embarcadero, that bird is a living argument for why pesticide regulation matters.
A good regional field guide will help you go deeper on any of these species. (Sibley’s Birds of Western North America)
