California is a large state with many varied habitats. As such, it enjoys a wide variety of birds. This page lists the most common backyard and neighborhood birds you are likely to see. We'll take a look at changes in seasonal composition of birds. Then we'll display some photos of the most common backyard birds and tell a little about them. Finally, we'll compare backyard birds in Los Angeles and San Francisco with the state as a whole and see what differences there are.

I've used the citizen science website eBird to create these lists of common backyard birds. The birds are ranked by frequency--how often they are recorded on a list of a birds submitted to eBird. These lists are from every habitat and location within the state. eBird itself doesn't separate backyard birds from other habitats--I have done that for you. Common birds that aren't found as often in backyards I've put into separate lists below the photo list.

Lists of the most common feeder birds and backyard birds in California

The birds listed at the top of the page are those most frequently encountered in backyards throughout the state and throughout the year. Many of the most common backyard birds are residents, but there are seasonal differences as well.

Winters are mild in much of the state. Many northern birds migrate to California for the winter. Yellow-rumped Warblers, White-crowned Sparrows, Ruby-crowned Kinglets, and Dark-eyed Juncos join the list of common backyard birds in winter, though each of these also nest in the mountains and northern parts of California, too. But they are supplemented in winter by individuals from as far away as Alaska.

The most common backyard birds in California in winter (December to February) are these:
1. Yellow-rumped Warbler (44% frequency)
2. Black Phoebe (44%)
3. White-crowned Sparrow (42%)
4. House Finch (39%)
5. Anna's Hummingbird (39%)
6. American Crow (36%)
7. California Scrub-Jay (31%)
8. Ruby-crowned Kinglet (29%)
9. Mourning Dove (28%)
10. California Towhee (26%)
11. European Starling (24%)
12. Song Sparrow (24%)
13. Dark-eyed Junco (24%)
14. Northern Flicker (22%)
15. American Robin (22%)
16. Golden-crowned Sparrow (21%)
17. Lesser Goldfinch (20%)

The most frequent summer backyard birds in California are primarily resident birds, though there are many migrants that come up from spending the winter in Mexico. These migrants are primarily insect-eaters and are more common in the forests than in lowland residential areas.

The most common backyard birds in California during the summer (June to July) are these:
1. House Finch (42% frequency)
2. Mourning Dove (39%)
3. Black Phoebe (31%)
4. Anna's Hummingbird (30%)
5. American Crow (29%)
6. California Scrub-Jay (28%)

1. House Finch (43% frequency of all eBird checklists)
Here is California's most common backyard bird. There are other red finches, but these are the ones most likely in residential areas.
Identification: This is a key species for comparing with an unknown bird. Size: About 6 inches from bill tip to tail tip. Larger than goldfinches and chickadees. Smaller than a White-crowned Sparrows or Spotted/Eastern towhees. Shape: Medium build with a medium-long notched tail. Round head. Bill: Short, conical. Color: Brown and gray above with streaks on the sides of the pale underparts. Males with red (sometimes orange or rarely yellow) crown, chest, rump. Habitat, range & behavior: You'll find small flocks on wires, in short tree tops and in bushes. Originally deserts and grasslands. Rural areas and towns are where they're now most common. Formerly found in the western United States and Mexico. Then introduced into the northeastern United States, but now found in nearly all of the lower-48 states and extreme southern Canada. Rare in plains states (Dakotas to Texas) and southern Florida. House Finches are not territorial, but males sing throughout the year--a lively, wiry song ending in a couple of buzzy notes. Food and feeder preference: They love sunflower seeds and tube feeders. May eat from thistle socks.

2. Black Phoebe (40%)
This perky little flycatcher should be familiar to most California residents.
Identification: Size: About the size of a White-crowned Sparrow or Spotted/Eastern towhee. Bigger than a House Finch. Much smaller than a European Starling. Shape: Big peaked head, pot belly, long slender tail. Bill: About half the length of the head, straight, very wide. Color: Sooty black upper parts and upper breast. White belly. Habitat, range & behavior: Found in lowlands near water, extensive lawns, and grassy backyards. Found in the western United States, most of Mexico, south into northern and western South America. May build their mud nests on porches or out buildings. Typical flycatching behavior: sitting still, then sallying out to grab a flying insect, and return to a perch with a bob of the tail. Food and feeder preference: Flying insects that they chase low over the lawn in aerial pursuits. They don't eat at bird feeders, but they need your bird bath to make mud for their nests.

3. Anna's Hummingbird (38%)
California's big resident hummingbird is everywhere there are people!
Identification: Size: Slightly larger than widespread hummingbirds like Ruby-throated in the east and Rufous Hummingbird in the west. Smaller than a goldfinch or chickadee. Shape: Plump, with long wings covering tail. Unmistakable long bill. Bill: Longer than head, round, slightly downcurved. Color: Green upper parts, gray under parts with greenish cast on sides. Male with entire head and throat covered in iridescent metallic rose pink. Female usually has pink throat spot. Habitat, range & behavior: Chaparral, open woods, suburban gardens all host this species. Formerly only in northern Baja and southern California they expanded to Arizona, and all the way to southern Alasak along the Pacific coast, following plantings of winter blooming flowers and the popularity of placing out hummingbird feeders. Nest early (December to February), even as they move north and encounter snow in winter. Food and feeder preference: Nectar and small insects is their main food. Both are available in flowering plants. Quickly find hummingbird feeders filled with sugar water.

4. American Crow (35%)
This larger all-black bird is common in cities and country. Its cawing call is familiar to most people. Identification: This is a key species for comparing with an unknown bird. Size: About 17-1/2 inches long from bill tip to tail tip, though there is much size variation throughout its range. Larger than blackbirds and grackles. Smaller than ravens. Shape: Thick neck, large head, rather short square-ended tail. Longer legs. In flight has rounded wing tips with each primary feather separated from others forming "fingers." Bill: As long as head, thick, black. Color: Glossy black throughout. Habitat, range & behavior: They prefer open areas with trees, fields, farms, cities. They are common across most of the United States lower-48, except in the desert southwest. They move into southern Canada in summer. They gather in evening communal roosts in large flocks that may number into the thousands and then move out at dawn into the surrounding area. Food and feeder preference: Omnivorous, they feed on large insects, grain, small mammals, carrion. You probably don't want these large entirely-black birds in your backyard feeders. So don't feed table scraps to birds.

5. Mourning Dove (34%)
Mourning Doves are the most widespread and most frequent backyard bird in the Lower 48 states of the United States.
Identification: This is a key species for comparing with an unknown bird. Size: About 12 inches long from bill tip to tail tip. About same size as Northern Flicker. Larger than American Robin. Slightly smaller than domestic city pigeon. Shape: Very plump with a small round head. Tail is long and pointed. Legs are short. Bill: Small and rather slender. Color: Pale brown-pink body, darker wings and tail. White edges on side of tail. Habitat, range & behavior: Semi-open areas such as urban areas, farmlands, woods. Often seen perched on wires, fences. It is a resident across the lower-48 states and Mexico, with some movement out of northern areas in winter. Their mournful cooing is a familiar spring birdsong. Food and feeder preference: Mourning Doves eat seeds almost exclusively. Attract with black oil sunflower seeds on a large sturdy tray feeder or on the ground.

6. California Scrub-Jay (32%)
This is California's common lowland jay, brash and noisy.
Identification: Size: This bird is the size of an American Robin or Northern Mockingbird. They are larger than a European Starling or Red-winged Blackbird. Smaller than a Mourning Dove. Shape: Strong body, thick neck, big head. Long legs. Fairly long full tail. Bill: Long, stout, curved near tip. Color: Deep azure blue upperparts, wings and tail with gray-brown back. Black bill and mask. White under parts with partial blue necklace across chest. Habitat, range & behavior: Oak woodlands, chaparral, residential areas. Found along west coast from northern Baja to Washington state. They forage on the ground, caching food to save for later. Food and feeder preference: Omnivorous, they eat insects, berries, small animals, bird eggs. At hopper and tray feeders they may harass other birds, and gulp down large quantities of black oil sunflower seeds and peanuts to go bury. Thus, some people put wire mesh cages over their hopper and tube feeders to keep the jays out--smaller birds can get through the mesh.

7. White-crowned Sparrow (29%)
A common winter visitor in California and resident along the coast and in the higher mountains.
Identification: This is a key species for comparing with an unknown bird. Size: About 7 inches. A large sparrow near size of Spotted/Eastern towhee. Larger than House Finch. Smaller than Starling or Red-winged Blackbird. Shape: Longer plump body, round head, long tail. Bill: Short and conical. Color: Brown back, wings, tail, gray under parts, black-and-white striped crown. For their first year immature birds have tan and reddish-brown striped crowns. Habitat, range & behavior: Open and shrubby areas. Coastal form in California at edge of sand dunes. Common winter form in California breeds on Arctic tundra. Various forms breed across the Arctic Canada and Alaska and in mountains in western Canada and the United States. They sing in spring migration as they move northward. Different populations have slightly different songs. Food and feeder preference: Weed seeds, grain, insects. Eat black oil sunflower seeds and other seeds on hopper and tray feeders.

8. Yellow-rumped Warbler (28%)
An abundant winter visitor in California to tree tops and weedy areas.
Identification: Size: Small, they are a bit larger than chickadees and goldfinches. They are smaller than House Finches and juncos. Shape: Plump and neckless with a shorter tail. Bill: Short, slender, straight, pointed. Color: Breeding plumage in spring is blue-gray on the upper parts, black sides and chest, yellow rump, yellow on sides. Two forms: western form with yellow throat and large white wing patch; eastern and northern form with white throat and two white wing bars. In winter plumage both forms are gray brown above, pale cream below. Yellow rump and white tail corners in flight. Habitat, range & behavior: In breeding season mostly in coniferous or mixed forests, in mountains in west. In winter open areas with fruiting shrubs and scattered trees. Breed across Canada and Alaska and in conifer forests in the west. Winter along both coasts and the southern states through Middle America. There are also non-migratory forms in Mexico and Guatemala. They tend to forage in outer branches about half way up the tree. Food and feeder preference: Mainly insects in the summer, they switch to waxy berries and fruit in winter. They are thus able to winter farther north than other warblers. They are attracted to suet feeders.

9. California Towhee (28%)
This is a plain but common bird in California.
Identification: Size: Longer than a European Starling or Red-winged Blackbird. Smaller than an American Robin. Much larger than Spotted/Eastern towhees. Shape: Large heavy sparrow with short neck, large head, large full tail. Bill: Short, stout, conical. Color: Dusty brown with rusty under tail coverts. Habitat, range & behavior: Found in chaparral scrub from Baja Sur to SW Oregon. Scratches among leaf litter on ground to find food. Unlike many chaparral birds, when the residential landscape encroached, rather than flee, it moved right into the backyard! Food and feeder preference: Primarily seeds and insects. They will eat mixed seeds in a tray feeder or on the ground under the feeder.

10. Song Sparrow (27%)
A common bird, but variable, and similar to many other streaked brown sparrows.
Identification: Size: A smaller bird, similar in size to House Finch and juncos. Larger than chickadees and goldfinches. Smaller than White-crowned Sparrows or Spotted/Eastern towhees. Shape: Plump with round head, long rounded tail. Bill: Short, conical. Color: Highly variable in darkness and color saturation across its range (dark rusty to pale gray). Generally gray-brown above with dark brown streaking on back. Complicated head pattern. Streaking on sides and breast converge into dense central breast spot. Habitat, range & behavior: Thickets, especially near water. Backyard shrubbery. Resident in western United States, western Canada, coastal southern Alaska, northeastern US. In summer also moves into mid-Canada and northern half of US. In the winter found in most of the US lower-48. Also a population in central Mexico. Forages on ground, never far from low cover to which they fly if startled. Food and feeder preference: They feed on seeds and insects near the ground. Will visit hopper and tray feeders for mixed bird seed.

11. European Starling (25%)
Introduced to North America in the late 1800's, they crossed the continent, often to the detriment of native cavity-nesting birds. The prime example of an invasive species.
Identification: Size: About the size of a Red-winged Blackbird. Smaller than an American Robin. Larger than a White-crowned Sparrow or Spotted/Eastern towhee. Shape: Stocky with large head, short square-ended tail. Longer legs. Bill: As long as head. Sharp pointed. Yellow in spring, otherwise dark. Color: They are grayish brown much of the year, with glossy iridescence and white spotting during the spring. Habitat, range & behavior: Lowland birds that need trees large enough for nest cavities but plenty of open area for feeding. They are most abundant in urban and suburban areas where they find food and artificial nest cavities. Resident from coast-to-coast from southern Canada to northern Mexico. In summer north across Canada and Alaska. Native range is Europe to Pakistan, north Africa. Often viewed as a pest, starlings often bully other backyard birds, taking over bird feeders, and stealing nest cavities from smaller native birds. In winter they can form into flocks of ten's of thousands. Food and feeder preference: Primarily insects when available, often feeding on the ground. Discourage them from your backyard hopper and tray feeders by never feeding birds table scraps (including bread or meat). They have weak feet and do not perch well on tube feeders. A cage mesh around smaller hopper feeders may keep them out.

12. Lesser Goldfinch (24%)
This bird replaces American Goldfinch in drier parts of the southwestern US.
Identification: Size: A small bird. Slightly smaller than American Goldfinch, but close. Shape: Big head, neckless, short forked tail. Bill: Short, small, conical. Color: Green back, yellow underparts including under tail coverts. Black wings and tail with white marks. Male with black cap on forecrown. Keeps the same bright yellow plumage year-round, unlike American Goldfinch. Habitat, range & behavior: Open scrubby woodlands of oak or other trees, fields, grasslands. Found in the western and southwestern US, into the Great Basin in summer. Found southward to Middle America. They sometimes gather into flocks of hundreds to feed in weedy fields. Food and feeder preference: They eat mostly thistle seeds, some insects. At your feeder they will eat black oil sunflower seeds at a tube feeder, but prefer Nyjer seeds in a "thistle sock" feeder.

You may find the nests of these birds about 6-8 feet off the ground under the lower limbs of conifers or similar bushy tree. Nests look like an old sock hanging in the tree. They are made of lichens and similar plant material and hair, held together by spider webs.
Identification: Size: Bushtits are tiny birds. Near the size of a hummingbird. Smaller than a goldfinch or chickadee. Shape: Plump with a round head and long rounded tail. Bill: Short, straight, stout. Color: Gray throughout with a browner head. Interior birds are paler. Habitat, range & behavior: Found in open woods, scrub, chaparral. Bushtits are birds of the western United States and Mexico. During most of the year they are found in large twittering flocks. They fly weakly, single file, from bush to bush. Food and feeder preference: Eat many types of insects. Find them in winter in shrubs up next to houses. To attract them to your backyard offer a suet block.

15. Dark-eyed Junco (20%)
Colloquially called "snow birds," they often arrive in backyards in winter from nearby mountain forests or more northern climes.
Identification: Size: Small birds about the size of a House Finch. Shape: Round body, short neck, round head, fairly long square-ended tail. Bill: Short, pointed, conical, pink. Color: Eastern birds are a darker all-gray with white belly. Western birds have jet black hood over head, brown back, and pink sides. Habitat, range & behavior: Breed in coniferous forests. Winters widely. Avoids heavy brush, preferring widely spaced bushes. Breeds across most of Canada, Alaska, and the western half of the United States. Winters from southern Canada and all of the lower 48-states to extreme northern Mexico. Spend much of their time hopping and feeding on the ground. Food and feeder preference: Eats mostly seeds, also insects in summer. Readily feed at backyard feeders on mixed seeds on hopper or tray feeders and ground.

17. Northern Mockingbird (20%)
This bird sings from exposed perches most of the year and often through the night. They have an unending supply of their own unique short phrases that they repeat about 3 times each, but frequently intersperse songs of other birds.
Identification: Size: The length of an American Robin. Shape: Slender and long-tailed. Long legs. Bill: Medium length, slender, slightly curved. Color: Gray, darker above, with white patches in wing and tail. Habitat, range & behavior: They prefer edge habitat with scattered trees and bushes, parks and residential areas. It is found in eastern and southern parts of the US, West Indies, and south into Mexico. In summer birds are found a bit farther north. They boldly defend their nests from other birds, cats, and intruders. Food and feeder preference: Eats insects, berries, and fruit. You may attract mockingbirds to your feeder with grapes, raisins, apple slices. They will come to a suet block. They readily use a bird bath.

What other common birds might you see from your backyard in California?

The following birds you may see in your backyard, neighborhood, or perhaps flying over. You could see many additional species depending upon whether your property is bordered by woods, lakes, or beaches.

The birds listed here are all common birds, whether normally found in backyards or adjoining lands or airspace.

Watch for these additional common California birds in winter (December to February):
Red-tailed Hawk (31% frequency)
American Coot (29%)
Mallard (28%)
Common Raven (26%)
Turkey Vulture (23%)
Double-crested Cormorant (21%)
Great Egret (20%)

Here is a list of California summer birds (June to July) not on the lists at the top of the page:
Common Raven (25% frequency)
Turkey Vulture (23%)
Mallard (22%)

There are a few migrant swallows, warblers, and a grosbeak on the list of spring birds you might see in your backyard in California. Some make this list as they have distinctive calls or songs or breeding displays, and may be quieter during the rest of the year, so aren't as detected as frequently, even though they may be present year-round. Many more are possible, but these are the most frequent.

Additional birds you may see in your backyard during spring migration (April-May):
Red-winged Blackbird (23% frequency)
Northern Mockingbird (23%)
Bewick's Wren (20%)
Wilson's Warbler (19%)
Black-headed Grosbeak (19%)
Orange-crowned Warbler (18%)
Acorn Woodpecker (18%)
Cliff Swallow (18%)
House Sparrow (18%)
Nuttall's Woodpecker (18%)
Barn Swallow (18%)
California Quail (18%)

Comparing the most common backyard birds of Los Angeles, California

These are the most common backyard birds throughout the year in Los Angeles County, California:
House Finch (61% frequency)
Mourning Dove (54%)
Black Phoebe (50%)
Anna's Hummingbird (44%)
American Crow (41%)
Northern Mockingbird (39%)
Yellow-rumped Warbler (39%)
Lesser Goldfinch (39%)
California Towhee (38%)
Common Raven (36%)
Bushtit (35%)
California Scrub-Jay (34%)
Allen's Hummingbird (33%)
Mallard (32%)
White-crowned Sparrow (30%)
Red-tailed Hawk (29%)
House Sparrow (27%)
European Starling (27%)
American Coot (26%)
Song Sparrow (25%)
Rock Pigeon (24%)
Spotted Towhee (21%)
Bewick's Wren (20%)
Nuttall's Woodpecker (20%)

There are a couple of birds that are more common in Los Angeles than in the state as a whole. The Mockingbird is especially common in southern California backyards. Allen's Hummingbird is restricted to the coastal strip the length of the state, but there is a resident population in southern California. Farther north in California, Allen's Hummingbirds are only spring and summer birds. Bushtit is a resident in California, but more common in the coastal sage scrub habitat surrounding residential areas in Los Angeles and southern California. They are common backyard birds.

These are the most common backyard birds throughout the year in San Francisco County, California:
Anna's Hummingbird (54%)
White-crowned Sparrow (50%)
Western Gull (49%)
Black Phoebe (41%)
Song Sparrow (40%)
House Finch (40%)
Common Raven (39%)
America Robin (38%)
Rock Pigeon (37%)
Yellow-rumped Warbler (32%)
Dark-eyed Junco (32%)
Pygmy Nuthatch (31%)

Chestnut-backed Chickadee (29%)
California Towhee (28%)
Double-crested Cormorant (27%)
Red-tailed Hawk (27%)
California Scrub-Jay (26%)
Mallard (25%)
European Starling (24%)
Golden-crowned Sparrow (22%)
Brewer's Blackbird (21%)
Townsend's Warbler (20%)
Bushtit (20%)

Chestnut-backed Chickadees reach south to the redwoods in San Francisco, but not much farther. The cool, damp conditions and resulting shrubs and bushes allow Dark-eyed Juncos to be common backyard birds, as well. I was really surprised at the Pygmy Nuthatches, though. These are birds of mature ponderosa pine forests in the mountains of the west. I was surprised to learn they are a backyard feeder birds in areas of San Francisco where Monterey pines occur.

Lesser Goldfinches prefer inland oak savanna or chaparral. Thus they are not a common bird in San Francisco. Surprisingly, Mourning Doves are found on less than 20% of checklists in San Francisco while they are much more common in the state as a whole, and Los Angeles especially.
