List of birds of California explained

This list of birds of California is a comprehensive listing of all the bird species seen naturally in the U.S. state of California as determined by the California Bird Records Committee (CBRC).[1] Additional accidental and hypothetical species have been added from different sources.

As of August 5, 2022, there are 681 species on the CBRC list. Two of these species are endemic, 13 were introduced by humans (directly or indirectly), one species has been extirpated, and one was extirpated in the wild but its reintroduction is in progress. Five additional species have been documented but "the CBRC could not reach a consensus as to whether records of these species involved true naturally occurring vagrants or escapes from captivity."

The following tags note species in each of those categories and one additional category:

Individuals or even flocks of many additional species have been recorded in California but these birds are assumed to be deliberately released or escaped from captivity. In the absence of evidence of wild origin, they are not included in the CBRC list.

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 623rd Supplement, published by the American Ornithological Society (AOS).[2] Common and scientific names are also those of the Check-list, except that the common names of families are from the Clements taxonomy because the AOS list does not include them.

Ducks, geese, and waterfowl

Order: AnseriformesFamily: Anatidae

The family Anatidae includes the ducks and most duck-like waterfowl, such as geese and swans. These birds are adapted to an aquatic existence with webbed feet, bills which are flattened to a greater or lesser extent, and feathers that are excellent at shedding water due to special oils.

Guans, chachalacas, and curassows

Order: GalliformesFamily: Cracidae

The chachalacas, guans, and curassows are birds in the family Cracidae. These are large birds, similar in general appearance to turkeys. The guans and curassows live in trees, but the smaller chachalacas are found in more open scrubby habitats. They are generally dull-plumaged, but the curassows and some guans have colorful facial ornaments.

New World quail

Order: GalliformesFamily: Odontophoridae

The New World quails are small, plump terrestrial birds only distantly related to the quails of the Old World, but named for their similar appearance and habits.

Pheasants, grouse, and allies

Order: GalliformesFamily: Phasianidae

Phasianidae consists of the pheasants and their allies, including partridges, grouse, turkeys, and Old World quail. These are terrestrial species, variable in size but generally plump with broad relatively short wings. Many species are gamebirds or have been domesticated as a food source for humans.

Grebes

Order: PodicipediformesFamily: Podicipedidae

Grebes are small to medium-large freshwater diving birds. They have lobed toes and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land.

Pigeons and doves

Order: ColumbiformesFamily: Columbidae

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere.

Cuckoos

Order: CuculiformesFamily: Cuculidae

The family Cuculidae includes cuckoos, roadrunners, and anis. These birds are of variable size with slender bodies, long tails, and strong legs. The Old World cuckoos are brood parasites.

Nightjars and allies

Order: CaprimulgiformesFamily: Caprimulgidae

Nightjars are medium-sized nocturnal birds that usually nest on the ground. They have long wings, short legs, and very short bills. Most have small feet, of little use for walking, and long pointed wings. Their soft plumage is cryptically colored to resemble bark or leaves.

Swifts

Order: ApodiformesFamily: Apodidae

The swifts are small birds which spend the majority of their lives flying. These birds have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have long swept-back wings which resemble a crescent or boomerang.

Hummingbirds

Order: ApodiformesFamily: Trochilidae

Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings. They are the only birds that can fly backwards.

Rails, gallinules, and coots

Order: GruiformesFamily: Rallidae

Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. The most typical family members occupy dense vegetation in damp environments near lakes, swamps, or rivers. In general they are shy and secretive birds, making them difficult to observe. Most species have strong legs and long toes which are well adapted to soft uneven surfaces. They tend to have short, rounded wings and to be weak fliers.

Cranes

Order: GruiformesFamily: Gruidae

Cranes are large, long-legged, long-necked birds. Unlike the similar-looking but unrelated herons, cranes fly with necks outstretched, not pulled back. Most have elaborate and noisy courting displays or "dances".

Stilts and avocets

Order: CharadriiformesFamily: Recurvirostridae

Recurvirostridae is a family of large wading birds which includes the avocets and stilts. The avocets have long legs and long up-curved bills. The stilts have extremely long legs and long, thin, straight bills.

Oystercatchers

Order: CharadriiformesFamily: Haematopodidae

The oystercatchers are large, obvious, and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.

Plovers and lapwings

Order: CharadriiformesFamily: Charadriidae

The family Charadriidae includes the plovers, dotterels, and lapwings. They are small to medium-sized birds with compact bodies, short thick necks, and long, usually pointed, wings. They are found in open country worldwide, mostly in habitats near water.

Sandpipers and allies

Order: CharadriiformesFamily: Scolopacidae

Scolopacidae is a large diverse family of small to medium-sized shorebirds including the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers, and phalaropes. The majority of these species eat small invertebrates picked out of the mud or soil. Different lengths of legs and bills enable multiple species to feed in the same habitat, particularly on the coast, without direct competition for food.

Pratincoles and coursers

Order: CharadriiformesFamily: Glareolidae

Pratincoles have short legs, very long pointed wings, and long forked tails. Their most unusual feature for birds classed as waders is that they typically hunt their insect prey on the wing like swallows, although they can also feed on the ground. Their short bills are an adaptation to aerial feeding.

Skuas and jaegers

Order: CharadriiformesFamily: Stercorariidae

Skuas and jaegers are in general medium to large birds, typically with gray or brown plumage, often with white markings on the wings. They have longish bills with hooked tips and webbed feet with sharp claws. They look like large dark gulls, but have a fleshy cere above the upper mandible. They are strong, acrobatic fliers.

Auks, murres, and puffins

Order: CharadriiformesFamily: Alcidae

Alcids are superficially similar to penguins due to their black-and-white colors, their upright posture, and some of their habits. However, they are only distantly related to the penguins and are able to fly. Auks live on the open sea, only deliberately coming ashore to nest.

Gulls, terns, and skimmers

Order: CharadriiformesFamily: Laridae

Laridae is a family of medium to large seabirds and includes gulls, terns, kittiwakes, and skimmers. They are typically gray or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet.

Tropicbirds

Order: PhaethontiformesFamily: Phaethontidae

Tropicbirds are slender white birds of tropical oceans with exceptionally long central tail feathers. Their long wings have black markings, as does the head.

Loons

Order: GaviiformesFamily: Gaviidae

Loons are aquatic birds, the size of a large duck, to which they are unrelated. Their plumage is largely gray or black, and they have spear-shaped bills. Loons swim well and fly adequately, but are almost hopeless on land, because their legs are placed towards the rear of the body.

Albatrosses

Order: ProcellariiformesFamily: Diomedeidae

The albatrosses are amongst the largest of flying birds, and the great albatrosses from the genus Diomedea have the largest wingspans of any extant birds.

Southern storm-petrels

Order: ProcellariiformesFamily: Oceanitidae

The storm-petrels are the smallest seabirds, relatives of the petrels, feeding on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Until 2018, this family's three species were included with the other storm-petrels in family Hydrobatidae.

Northern storm-petrels

Order: ProcellariiformesFamily: Hydrobatidae

Though the members of this family are similar in many respects to the southern storm-petrels, including their general appearance and habits, there are enough genetic differences to warrant their placement in a separate family.

Shearwaters and petrels

Order: ProcellariiformesFamily: Procellariidae

The procellariids are the main group of medium-sized "true petrels", characterized by united nostrils with medium septum and a long outer functional primary.

Storks

Order: CiconiiformesFamily: Ciconiidae

Storks are large, heavy, long-legged, long-necked wading birds with long stout bills and wide wingspans. They lack the powder down that other wading birds such as herons, spoonbills, and ibises use to clean off fish slime. Storks lack a pharynx and are mute.

Frigatebirds

Order: SuliformesFamily: Fregatidae

Frigatebirds are large seabirds usually found over tropical oceans. They are large, black or black-and-white, with long wings and deeply forked tails. The males have colored inflatable throat pouches. They do not swim or walk and cannot take off from a flat surface. Having the largest wingspan-to-body-weight ratio of any bird, they are essentially aerial, able to stay aloft for more than a week.

Boobies and gannets

Order: SuliformesFamily: Sulidae

The sulids comprise the gannets and boobies. Both groups are medium-large coastal seabirds that plunge-dive for fish.

Anhingas

Order: SuliformesFamily: Anhingidae

Anhingas are cormorant-like water birds with very long necks and long straight beaks. They are fish eaters which often swim with only their neck above the water.

Cormorants and shags

Order: SuliformesFamily: Phalacrocoracidae

Cormorants are medium-to-large aquatic birds, usually with mainly dark plumage and areas of colored skin on the face. The bill is long, thin, and sharply hooked. Their feet are four-toed and webbed.

Pelicans

Order: PelecaniformesFamily: Pelecanidae

Pelicans are very large water birds with a distinctive pouch under their beak. Like other birds in the order Pelecaniformes, they have four webbed toes.

Herons, egrets, and bitterns

Order: PelecaniformesFamily: Ardeidae

The family Ardeidae contains the herons, egrets, and bitterns. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to be shorter-necked and more secretive. Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises, and spoonbills.

Ibises and spoonbills

Order: PelecaniformesFamily: Threskiornithidae

The family Threskiornithidae includes the ibises and spoonbills. They have long, broad wings. Their bodies tend to be elongated, the neck more so, with rather long legs. The bill is also long, decurved in the case of the ibises, straight and distinctively flattened in the spoonbills.

New World vultures

Order: CathartiformesFamily: Cathartidae

The New World vultures are not closely related to Old World vultures, but superficially resemble them because of convergent evolution. Like the Old World vultures, they are scavengers. However, unlike Old World vultures, which find carcasses by sight, New World vultures have a good sense of smell with which they locate carcasses.

Osprey

Order: AccipitriformesFamily: Pandionidae

Pandionidae is a monotypic family of fish-eating birds of prey. Its single species possesses a very large and powerful hooked beak, strong legs, strong talons, and keen eyesight.

Hawks, eagles, and kites

Order: AccipitriformesFamily: Accipitridae

Woodpeckers

Order: PiciformesFamily: Picidae

Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails, and long tongues used for capturing insects. Some species have feet with two toes pointing forward and two backward, while several species have only three toes. Many woodpeckers have the habit of tapping noisily on tree trunks with their beaks.

Falcons and caracaras

Order: FalconiformesFamily: Falconidae

Falconidae is a family of diurnal birds of prey, notably the falcons and caracaras. They differ from hawks, eagles, and kites in that they kill with their beaks instead of their talons.

New World and African parrots

See also: feral parrots. Order: PsittaciformesFamily: Psittacidae

Characteristic features of parrots include a strong curved bill, an upright stance, strong legs, and clawed zygodactyl feet. Many parrots are vividly colored, and some are multi-colored. In size they range from 81NaN1 to 11NaN1 in length. Most of the more than 150 species in this family are found in the New World.

Tityras and allies

Order: PasseriformesFamily: Tityridae

Tityridae is family of suboscine passerine birds found in forest and woodland in the Neotropics. The approximately 30 species in this family were formerly lumped with the families Pipridae and Cotingidae (see Taxonomy). As yet, no widely accepted common name exists for the family, although tityras and allies and tityras, mourners, and allies have been used. They are small to medium-sized birds.

Tyrant flycatchers

Order: PasseriformesFamily: Tyrannidae

Tyrant flycatchers are Passerine birds which occur throughout North and South America. They superficially resemble the Old World flycatchers, but are more robust and have stronger bills. They do not have the sophisticated vocal capabilities of the songbirds. Most, but not all, are rather plain. As the name implies, most are insectivorous.

Vireos, shrike-babblers, and erpornis

Order: PasseriformesFamily: Vireonidae

The vireos and greenlets are a group of small to medium-sized passerine birds mostly restricted to the New World, though a few members of the family, called shrike-babblers, are found in Asia. They are typically greenish in color and resemble wood-warblers apart from their heavier bills.

Shrikes

Order: PasseriformesFamily: Laniidae

Shrikes are passerine birds known for their habit of catching other birds and small animals and impaling the uneaten portions of their bodies on thorns. A shrike's beak is hooked, like that of a typical bird of prey.

Crows, jays, and magpies

Order: PasseriformesFamily: Corvidae

The family Corvidae includes crows, ravens, jays, choughs, magpies, treepies, nutcrackers, and ground jays. Corvids are above average in size among the Passeriformes, and some of the larger species show high levels of intelligence.

Penduline-tits

Order: PasseriformesFamily: Remizidae

The only member of this family in the New World, the verdin is one of the smallest passerines in North America. It is gray overall and adults have a bright yellow head and rufous "shoulder patch" (the lesser coverts). Verdins are insectivorous, continuously foraging among the desert trees and scrubs. They are usually solitary except when they pair up to construct their conspicuous nests.

Kinglets

Order: PasseriformesFamily: Regulidae

The kinglets are a small family of birds which resemble the titmice. They are very small insectivorous birds. The adults have colored crowns, giving rise to their name.

Waxwings

Order: PasseriformesFamily: Bombycillidae

The waxwings are a group of birds with soft silky plumage and unique red tips to some of the wing feathers. In the Bohemian and cedar waxwings, these tips look like sealing wax and give the group its name. These are arboreal birds of northern forests. They live on insects in summer and berries in winter.

Silky-flycatchers

Order: PasseriformesFamily: Ptiliogonatidae

Treecreepers

Order: PasseriformesFamily: Certhiidae

Treecreepers are small woodland birds, brown above and white below. They have thin pointed down-curved bills, which they use to extricate insects from bark. They have stiff tail feathers, like woodpeckers, which they use to support themselves on vertical trees.

Gnatcatchers

Order: PasseriformesFamily: Polioptilidae

These dainty birds resemble Old World warblers in their structure and habits, moving restlessly through the foliage seeking insects. The gnatcatchers are mainly soft bluish gray in color and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (especially males) and long, regularly cocked, black-and-white tails.

Wrens
