House finches in California: Identification, calls, nests and year-round range

House finches live in California all year and are a common sight in neighborhoods statewide. CDFW's California Wildlife Habitat Relationships account describes the species as a common to abundant resident through much of California, missing mainly from mountain habitats and from dry regions far from water. They are easy to find in backyards, city parks, orchards, farms, oak woodland and desert oases from Northern California to Southern California.

The house finch is a native bird and is not listed as threatened or endangered. It is protected all the same. It is on the federal Migratory Bird Treaty Act list, and California law makes it unlawful to take the bird or to destroy its nest or eggs except as the Fish and Game Code allows.

This guide covers identification of males and females, where house finches live in California, their diet and nesting, their song and calls, their legal status and the two finches most often confused with them. It is part of our guide to the birds of California.

House finch at a glance: Key facts for California

House finch identification: Red males, streaky brown females and a shallow-notched tail:

The house finch is a small finch with a fairly large bill, a long and somewhat flat head and short wings that make the tail look long. Cornell Lab of Ornithology's All About Birds gives a length of 5.1 to 5.5 inches, a wingspan of 7.9 to 9.8 inches and a weight of 0.6 to 0.9 ounces. That is about the size of a house sparrow, though the finch is slimmer. The tail has only a shallow notch, a useful clue because many finches have deeply notched tails.

Adult males are rosy red on the face and upper breast, with a streaky brown back, belly and tail. The red rump stands out in flight. The shade of red varies: birds cannot make red pigments themselves, so males take them from the food they eat while molting, and a male on a poor diet can be orange or even yellow. All About Birds notes that redder males are more attractive to females.

Females have no red. A female house finch is plain grayish brown with thick, blurry streaks on the underparts and a face without strong markings. Young males look much like females.

House finches are social birds that often visit feeders in groups. They sit still while they crush seeds with quick bites, and their flight is bouncy like that of many finches.

House finches in California: Year-round residents from the coast to the desert oases:

House finches are native to California. All About Birds says the species originally lived in the western United States and Mexico. The birds in the eastern United States descend from cage birds marketed in the East as "Hollywood finches" and released on Long Island, New York, in 1940. Hawaii's house finches have a California link: birds were taken to Oahu from San Francisco before 1870.

In California, CWHR lists the species as most common in valley and foothill hardwood woodland, hardwood-conifer woodland, riparian woodland, desert riparian habitat, palm oases, orchards, vineyards and towns. It also uses open woodland, brushland, forest edges, grassland and desert. The account says the bird flourishes in urban and cropland habitats. In the mountains it is mostly limited to towns and farmland, with small numbers in wilder habitat at lower elevations and during migration.

House finches are mostly not migratory. East of the Cascade Range and Sierra Nevada the pattern changes. CWHR says much of the breeding population there apparently leaves for the winter. In Mono County, along the eastern base of the Sierra Nevada, the breeding birds leave for winter, but a large influx of migrants arrives in late summer. Some birds also wander in late summer, including short moves upslope.

House finch habitat, diet and nesting in California: Seeds, daily water and sheltered nest sites:

Seeds of grasses and forbs are the house finch's main food, and seeds of composite plants are especially favored. Buds, berries and other small fruits are also important. The birds eat only small amounts of insects. They feed on the ground or cling to stems to pick seeds and fruit, preferably near high perches such as trees, power lines and buildings where they can escape danger. All About Birds says nestlings are fed only plant food.

Water is a daily need. CWHR says house finches require water every day and may travel relatively long distances to drink, though fruit can partly substitute.

The nest site is usually shaded from above and often partly enclosed. House finches nest in dense foliage of trees, tall shrubs and vines, under eaves and in cavities of buildings, in crevices of cliffs and earthen banks, behind loose eucalyptus bark, in hollow limbs and in old nests of other birds. On the southern Channel Islands they often nest in cactus. Nests are usually 6 to 20 feet above the ground, though CWHR gives a range of 3 to 50 feet.

Nesting usually begins in March or April. A female lays two to six eggs, usually four or five, and pairs often raise two or even three broods a year. Incubation lasts 12 to 14 days. Both parents feed the young, which leave the nest at 14 to 16 days and are fed for several more days.

CWHR cites a Sacramento study in which domestic cats caused almost the entire loss of young. It also cites research finding that house sparrows compete strongly for nest sites and almost always won fights with house finches in California.

House finch calls and sounds: A long warbling song and a sharp cheep:

The male's song is a long, jumbled warble of short notes, usually lasting about three seconds and often ending with a slurred note that rises or falls, according to the All About Birds sound page. Females sometimes sing a shorter, simpler version. Both sexes give a sharp cheep call often, while perched and in flight, and a sharper version when they flush from the ground.

The song helps separate the house finch from its relatives. All About Birds describes the house finch's song as slower, rougher and less fluid than those of the purple finch and Cassin's finch, with the slurred ending heard more often.

House finch legal status in California: A protected nongame bird:

The house finch is not listed as endangered or threatened, is not fully protected and is not a game bird. Three overlapping laws protect it.

• Nongame bird. Fish and Game Code section 3800 defines every naturally occurring bird that is not a game bird or fully protected as a nongame bird and makes it unlawful to take one except as the code or Fish and Game Commission rules allow.
• Nests and eggs. Section 3503 makes it unlawful to take, possess or needlessly destroy the nest or eggs of any bird except as the code allows.
• Migratory birds. The house finch is on the federal Migratory Bird Treaty Act list in 50 CFR 10.13. Section 3513 makes it unlawful under state law to take or possess any bird on that list except as federal rules allow.

The official state checklist kept by the California Bird Records Committee lists the species as House Finch, Haemorhous mexicanus, and does not mark it as introduced.

Similar species to the house finch in California: Purple finch and Cassin's finch:

All About Birds lists two close relatives, the purple finch and Cassin's finch, among the species most similar to the house finch. Both are on California's official list in the same genus, Haemorhous, and habitat is a useful first clue.

The purple finch is a common resident in Northern California and fairly common in the south, CDFW's purple finch account says. It occurs in coastal foothills and lowlands and breeds in moist, shady conifer, hardwood and riparian forest at middle elevations. From October to April it becomes more widespread in the foothills and lowlands west of the Sierra Nevada crest and in Southern California.

Cassin's finch is a mountain bird. CDFW's Cassin's finch account calls it a common resident of most of the higher ranges, in tall, open forests of lodgepole pine, red fir and subalpine conifers, especially near wet meadows.

By those accounts, a red finch at a feeder in a lowland town or farm fits the house finch's habitat, while one in a high conifer forest deserves a closer look. All About Birds also lists the female house sparrow and the pine siskin among the birds that resemble the house finch.

The state list includes other finches as well, among them the lesser, Lawrence's and American goldfinches, the pine siskin, the red crossbill, the evening and pine grosbeaks and the gray-crowned rosy-finch.

House finches in California: A native finch at home in towns, farms and woodland:

House finches in California are year-round neighbors across most of California, absent mainly from the high mountains and from dry country without water. The red males, streaky brown females and warbling song are easy to learn. The house finch is common, but state and federal law protect the bird and its nests and eggs. Our guides to the mourning dove and California scrub-jay cover two more of California's familiar backyard birds.
