The small brown birds that can be regularly seen in California backyards are wrens, which are tiny birds with a loud voice. The most common wren species in California is the House Wren.

If you're interested in attracting small birds to your yard, consider installing a platform feeder or hopper feeder. Most backyard birds in California prefer platform feeders, with 92.5% of species using them.

Some of the small birds you might see at your feeder include the House Finch, Golden-crowned Sparrow, and White-crowned Sparrow. These birds are among the top 10 most frequently reported backyard feeder birds in California.

Here's a list of some of the small birds you might see in California:

The Rock Wren is a compact little songbird with a powerful singing voice, most often observed perched on an exposed rock while flicking its tail energetically.

These small wrens are inconspicuously colored, with a gray-brown and white speckled plumage, and a slight tint of reddish orange on their rump.

California birds are resident, and can be seen in the Golden State year-round, although they sometimes move to lower altitudes in cold weather.

Bewick's Wrens are brown on the back, wings, and cap, with a pale throat and breast that grades to grayish.

They are shy at feeders and don't stay out of dense vegetation for long periods of time, but can be attracted with mealworms, suet, hulled sunflower seeds, and peanuts.

Bewick's Wrens favor dense vegetation, tangled understory, or brush piles that they use to approach bird feeders and return for cover.

They build a bulky oven-shaped nest with a side entrance, placed in broken-off stumps and limbs 3-6 feet above the ground, or in hanging planters and decorations on porches.

The Rock Wren is a compact little songbird with a powerful singing voice.

They're often observed perched on an exposed rock, flicking their tail energetically.

These small wrens are inconspicuously colored, with a gray-brown hue and white speckles.

A slight tint of reddish orange can be seen on their rump, and white speckles adorn their crown and back.

Northern populations of Rock Wrens are migratory, but California birds are resident and can be seen year-round.

In cold weather, they may move to lower altitudes.

They forage for insects on the ground with a bouncy gait, while flicking their tail.

The Cactus Wren is a year-round resident of the southern half of California, commonly found in desert landscapes.

It's often seen perched on cacti, using them as a lookout to search for insects and other small invertebrates on the ground.

This bird's brown crest, long and slightly downturned bill, and bright white eyebrow stripe are its most distinguishing features.

The Cactus Wren's harsh, chattering call sounds like someone trying to start a car, and if you get close enough, you'll notice its dark ruby red eyes.

Both sexes of this bird look alike, with a predominantly grayish-brown plumage featuring dark brown spots and streaks.

The Bewick's Wren is a great bird to attract to your backyard, and it's relatively easy to do so. Attract them with mealworms, suet, hulled sunflower seeds, and peanuts.

They're not too picky about their feeders, but they do favor large or small hopper feeders, tube feeders, suet cages, and the ground. This means you can choose the type of feeder that best suits your needs.

Bewick's Wrens are year-round residents in Coastal California, which is great news for bird enthusiasts in that area. They're also known to be shy at feeders and don't stay out of dense vegetation for long periods of time.

They're submissive to most other birds, which is a good thing to keep in mind if you're trying to attract a variety of species to your yard. To encourage them to visit, make sure to provide dense vegetation, tangled understory, or brush piles that they can use to approach feeders and return for cover.

The Bewick's Wren builds a bulky oven-shaped nest with a side entrance, which is a unique and interesting aspect of their behavior. They place their nests in broken-off stumps and limbs 3-6 feet above the ground, or even in hanging planters and decorations on porches.

Their breeding season is from late Mid-April through Mid-August, and during this time they lay 3-7 creamy-white eggs with brown to reddish-brown spots. It takes about 30 days from egg-laying until the young birds fledge.

Hummingbirds are a delight to spot in California, and with their iridescent feathers and rapid wing movement, it's no wonder why they're a favorite among bird enthusiasts.

The Anna's Hummingbird, for example, is the smallest bird found in California, and it's a common sight in backyards and gardens throughout the state.

Males have a distinctive iridescent purple crown, but females and juvenile birds have more subdued hues, with gray-brown upperparts and a lighter gray underside.

One of the most impressive things about Anna's Hummingbirds is their ability to adapt to different environments, and they can be found in a wide range of habitats, from coastal California to urban areas.

Black-chinned Hummingbirds, on the other hand, are generalists and can thrive in many different habitats, including remote deserts and mountains, as well as parks and backyard gardens.

These tiny birds are not as aggressive as some other species of Hummingbirds, and are often dominated by other Hummingbirds.

If you're lucky enough to spot a Black-chinned Hummingbird, you'll notice that males have a dark head and black throat, while females and immature birds are more drably colored.

Anna's Hummingbirds, by contrast, are highly adaptable when it comes to foraging for food, and can utilize a broad range of nectar sources, including flowering trees and shrubs from different continents.

The yellow-rumped warbler is a non-aggressive visitor to feeders, often submissive to other birds. It's a great bird to attract to your backyard, particularly if you have semi-open woodland or yards with flocks of birds.

To attract yellow-rumped warblers, try offering hulled sunflower seeds, suet, peanuts, peanut hearts, nectar, fruit, and mealworms at large and small tube feeders, suet cages, large and small hopper feeders, and fruit and nectar feeders. They favor these types of feeders and food sources.

They can be expected at backyard bird feeders any time of the year in California, as they are present throughout the year.

The Golden-crowned Sparrow has a distinctive golden-yellow crown stripe, while the White-crowned Sparrow has black and white stripes on the crown. Both species are found in California, with the Golden-crowned Sparrow present in the western half of the state during Fall and Winter, and the White-crowned Sparrow found throughout the state year-round.

The Golden-crowned Sparrow prefers to feed on the ground or on a platform, while the White-crowned Sparrow feeds mainly on the ground but will also take platform feeders. Both species are ground feeders and can be pushed aside from platform feeders by more aggressive birds.

Here's a brief comparison of the two species:

Both species build their nests on or near the ground, with the Golden-crowned Sparrow building a bulky cup made of grasses, leaves, and bark, and the White-crowned Sparrow building a cup-shaped nest in shrubs or bushes.

Small brown birds are a delight to spot in California backyards. The House Wren is one of the most common small brown birds in California, found throughout the state in summer.

Female House Finches are also small brown birds that are commonly found in backyard gardens all over California. They're brownish-gray in color.

Wrens are tiny birds with a loud voice, and the House Wren is the most common wren species in California. Rock Wrens replace them in more remote mountainous areas.

Here's a list of some small brown birds you might spot in California:

These birds are great to attract to your backyard with the right type of feeder. In California, platform feeders are the most popular choice among backyard birds, followed by large hopper feeders.

The Cassin's Finch is a year-round visitor to backyard feeders in the eastern half of California, and they can be attracted with a variety of seeds such as black oil sunflower seeds, hulled sunflower seeds, nyjer, and millet.

These birds are primarily seed-eaters, so it's essential to provide a seed-rich environment. They are not aggressive at feeders, making them a great addition to any bird-watching experience.

Cassin's Finches prefer backyards with a mix of open spaces, shrubs, and trees, as well as a source of water. They are not picky about their water source, so a simple birdbath will do.

Their cup-shaped nests are made of twigs, grasses, and rootlets, lined with soft materials like hair or feathers. The female lays 3-6 greenish eggs with dusky specks, and it takes approximately 26 days from egg-laying until fledging.

Cassin's Finches breed in the late spring and summer, from May to July, and they can live at least 7 years.

The White-Crowned Sparrow is a large and relatively long-tailed sparrow with black and white stripes on its crown (adults). It has a gray head and breast area. The bill color varies from yellow-orange to pink.

Immature birds have tan and brown head stripes. They can be expected at feeders all year-round.

Attract White-Crowned Sparrows with black oil and hulled sunflower seeds, cracked corn, millet, and milo. They feed mainly on the ground but also take platform feeders.

Take a look at this: Bird Head

Like other ground feeders, White-Crowned Sparrows interact peacefully with other ground feeders. They can be pushed aside from platform feeders by more aggressive birds.

The White-Crowned Sparrow favors overgrown fields and brushy areas, particularly during migration. Yards that resemble this habitat type are likely to attract them.

White-Crowned Sparrows build a cup-shaped nest in shrubs or bushes at various heights (2-5 feet) from the ground. They can also nest on the ground where tall shrubs are not available.

The White-Crowned Sparrow's breeding season varies regionally but is generally from May through mid-August. They lay 3-7 bluish to greenish eggs spotted with brown concentrated on the wide side of the egg.

It takes about 22 days from egg-laying (incubation period 13 days, nestling period 9 days) until fledging. White-Crowned Sparrows live at least 13 years and 4 months.

Here's a comparison between the White-Crowned Sparrow and the Golden-Crowned Sparrow:

Towhees are a type of bird that can be found in California, and they're quite fascinating.

The Spotted Towhee has a distinctive black hood and breast with white spots, while the California Towhee is a more subtle gray-brown bird with a rusty lower belly.

Spotted Towhees are attracted to black oil sunflower seeds, hulled sunflower seeds, safflower, cracked corn, peanut hearts, millet, and milo, making them a great addition to your backyard bird feeder.

In contrast, California Towhees are also drawn to these same food sources, but their range is restricted to the State of California where they're a year-round resident.

Both Spotted and California Towhees are largely ground feeders, taking seeds spilled below elevated feeders and using platform feeders and hopper feeders.

You can expect to see Spotted Towhees in your backyard feeders during the fall and winter months, while California Towhees can be expected at backyard bird feeders any time of the year.

Spotted Towhees are more likely to visit backyard feeders located adjacent to dense low vegetation, while California Towhees prefer scrub or mixed scrub vegetation.

The Spotted Towhee lays 2-6 white to greenish eggs speckled with reddish spots, while the California Towhee lays 2-5 white to bluish eggs speckled with reddish brown spots.

Spotted Towhees live at least 11 years, while California Towhees live at least 12 years and 8 months.

The California scrub-jay is a stunning bird with a striking appearance. Its head, neck, wings, and tail are a brilliant blue, with a creamy white throat and breast, and a brown belly.

One of the most distinctive features of the California scrub-jay is its long tail. This bird is a food generalist, eating just about anything put on bird feeders, including cracked corn, peanuts, peanut hearts, and black oil sunflower seed.

They favor platform and large hopper feeders, and are not afraid to take food from the ground. In fact, they're often seen foraging on the ground for seeds and other treats.

California scrub-jays are year-round residents in the State of California, and can be found in areas dominated by scrub and deciduous habitats. They're aggressive and dominant at feeders, but will submit to crows, grackles, and some woodpeckers.

These birds are expert nest-builders, constructing large nests with a central cup lined with fine material, usually about 7-8 feet above the ground. The breeding season for California scrub-jays typically runs from mid-March through mid-July.

Female California scrub-jays lay 2-5 greenish spotted with brown eggs, which incubate for 18 days before hatching. The nestling period is also 18 days, after which the young birds fledge.

The red-bellied woodpecker is a common visitor to backyard bird feeders in California, often taking seeds from feeders to cache elsewhere for later consumption.

In California, you can attract three types of woodpeckers to your backyard bird feeders: the red-bellied woodpecker, and two other species that we'll discuss further.

The Northern Flicker is one of the largest woodpeckers in California, with a warm brown color and black barring on its back and wings.

It has a distinctive black crescent on its chest, and males have a black malar stripe that's missing in females.

Northern Flickers can be expected at feeders any time of the year in California, and they're not particularly aggressive to other birds at feeders, but they do dominate smaller-sized birds.

These birds favor semi-open habitats with plenty of open ground, including suburban areas, and they're known to nest in cavities they excavate in rotten wood.

Northern Flickers breed from May through early August, and they lay 5-8 pure white and unmarked eggs that take about 37 days to hatch.

Backyard birds are a delight to watch and learn about. In California, the most common backyard feeder birds are sparrows, finches, and their allies, which include siskins, goldfinches, grosbeaks, and juncos.

Most of these birds have heavy, conical, seed-crushing bills, perfect for eating seeds and grains. They also take more insects and other invertebrates during the breeding season.

Some of the most frequently reported backyard feeder birds in California include the Cassin's Finch, House Finch, Golden-crowned Sparrow, White-crowned Sparrow, and Spotted Towhee. These birds can be year-round residents or migratory, which is why you might see different species visiting your feeders at different times of the year.

The type of bird feeder to get in California is a platform feeder or hopper feeder, particularly if you're just starting to feed backyard birds. According to data from the FeederWatch Project, most birds (92.5%) use platform feeders, followed by large hopper feeders (64.8%). Many birds (32%) are comfortable feeding on the ground.

Here are the top 5 bird feeder types used by backyard birds in California:

With the right feeder and some basic knowledge, you can attract these wonderful birds to your backyard and enjoy their company for years to come.

Gulls, terns, and skimmers are medium to large seabirds with stout, longish bills and webbed feet. They're typically gray or white, often with black markings on the head or wings.

Some common species of gulls include the Ring-billed gull, Western gull, and Herring gull. The Ring-billed gull is easily recognizable by its distinctive black ring around its beak.

If you're looking for shorebirds, keep an eye out for sandpipers, which include species like the Sanderling and the Dunlin. These birds are small to medium-sized and have distinctive length variations in their bills and legs, allowing them to feed in the same habitats without direct competition for food.

Here's a list of some common seabirds and shorebirds found in California:

Stilts and avocets are part of the Charadriiformes order, which also includes other wading birds. They're known for their unique characteristics.

The avocets have long legs and long up-curved bills. This distinctive feature helps them forage for food in shallow waters.

Terns are another type of seabird that are known for their distinctive calls and agile flight. Some common tern species include the Sooty tern, Bridled tern, and Caspian tern.

Swallows are a group of birds that are well adapted to aerial feeding. They have slender, streamlined bodies and long, pointed wings that allow them to fly efficiently.

The family Hirundinidae is made up of birds with short bills and a wide gape, perfect for catching insects in mid-air. This adaptation is crucial for their survival.

Some common species of swallows include the Bank swallow, Tree swallow, and Barn swallow. These birds can be found in a variety of habitats, from open fields to coastal areas.

The feet of swallows are adapted for perching rather than walking. The front toes are partially joined at the base, providing extra support when perched.

Here's a list of some of the swallows mentioned earlier:

As you explore California's diverse regions, you'll notice differences in the Western Scrub Jay's appearance. The two recognized subspecies, redivivum and sonomae, have distinct plumage characteristics.

The redivivum subspecies, found in the south, is paler, with a grayish-brown back and buffy undertail coverts.

Regional Differences are a fascinating aspect of bird species. Ornithologists recognize two subspecies of a particular bird species, each with distinct characteristics.

In the southern region, the redivivum subspecies is found from Baja California north to southern Santa Cruz and Placer Counties. This subspecies is paler in color, with a grayish brown hue above and buffy undertail coverts.

The northern region is home to the sonomae subspecies, found from northern Santa Cruz and El Dorado Counties northward. This subspecies is a rich brown above, with almost chestnut undertail coverts.

The sonomae subspecies has a buffy throat, while the redivivum subspecies has a grayish throat.

In Southern California, you can expect to see a variety of birds visiting your backyard or local park during different seasons.

The Cassin's Finch, House Finch, and Golden-crowned Sparrow are among the top 5 most frequently reported backyard feeder birds in the State of California, and they can be seen year-round.

During the winter months, birds like the Mourning Dove, Northern Mockingbird, and European Starling may visit your feeder, as they are not as abundant in the area during other times of the year.

If you're setting up a bird feeder in Southern California, it's a good idea to get a platform feeder or hopper feeder, as these are the most popular types among backyard birds in the state.
