List of birds of the United States

A comprehensive listing of all the bird species confirmed in the United States follows. It includes species from all 50 states and the District of Columbia as of July 2021. Species confirmed in other U.S. territories are also included with other "as of" dates.

The birds of the continental United States most closely resemble those of Eurasia, which was connected to the continent as part of the supercontinent Laurasia until around 60 million years ago. Many groups occur throughout the Northern Hemisphere and worldwide. However some groups unique to the New World have also arisen; those represented in the list are the hummingbirds, the New World vultures, the New World quail, the tyrant flycatchers, the vireos, the mimids, the New World warblers, the tanagers, the cardinals, and the icterids.

Several common birds in the United States, such as the house sparrow, the rock pigeon, the European starling, and the mute swan are introduced species, meaning that they are not native to North America, but were brought there by humans. Introduced species are marked as (I). In addition, many non-native species which have individual escapees or small feral populations in North America are not on the list. It is especially true of birds that are commonly held as pets, such as parrots and finches.

The status of one bird on the list, the ivory-billed woodpecker, is controversial. Until 2005, the bird was widely considered to be extinct. In April of that year, it was reported that at least one adult male bird had been sighted in the Cache River National Wildlife Refuge in Arkansas. The report, however, has not been universally accepted, and the American Birding Association still lists the ivory-billed woodpecker as extinct.

Hawaii has many endemic bird species (such as the Kauaʻi ʻelepaio) that are vulnerable or endangered, and some have become extinct. The number of birds on Guam has been severely reduced by introduced brown tree snakes^[1][2] — several endemic species on Guam (such as the Guam flycatcher) have become extinct, while others (such as the Guam rail) have become extinct in the wild. Guam rails have since been reintroduced to the wild on Guam and Rota.^[3] There are many endemic bird species in Puerto Rico and the Northern Mariana Islands, while American Samoa has South Pacific bird species (such as the many-colored fruit dove) found in no other part of the United States.^[4][5][6]

Sources and geographic coverage[]

The majority of this list is derived from the Check-list of North and Middle American Birds, 7th edition through the 61st Supplement, published by the American Ornithological Society (AOS)^[7] and the Bird Checklists of the World (Avibase).^[8] The geographic territory of that source which applies to the article is the 48 contiguous states, the District of Columbia, Alaska, Hawaii, the adjacent islands under the jurisdiction of those states, Puerto Rico, and the American Virgin Islands.

The article also includes birds found in the other U.S. territories (American Samoa, Guam, the Northern Mariana Islands, and the U.S. Minor Outlying Islands). In total, the list of birds in the article includes bird species found in the 50 states, the District of Columbia, and all U.S. territories.

The source for birds in the U.S. territories is the Avibase website: Bird checklists of the world (American Samoa),^[6] Bird checklists of the world (Guam),^[3] Bird checklists of the world (Northern Mariana Islands),^[5] Bird checklists of the world (Puerto Rico),^[4] Bird checklists of the world (United States Virgin Islands),^[9] and Bird Checklists of the world (U.S. Minor Outlying Islands).^[10]

When a bird's presence in the U.S. only occurs within a U.S. territory such as Puerto Rico, the name of the territory is noted alongside the bird's name.

Taxonomy and status[]

For species found in the 50 states, Puerto Rico, and the U.S. Virgin Islands, the taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) used in the list are those of the AOS, the recognized scientific authority on the taxonomy and nomenclature of North and Middle American birds. However, the common names of families are from the Clements taxonomy because the AOS list does not include them. The AOS's Committee on Classification and Nomenclature, the body responsible for maintaining and updating the Check-list, "strongly and unanimously continues to endorse the biological species concept (BSC), in which species are considered to be genetically cohesive groups of populations that are reproductively isolated from other such groups".^[7] The sequence and names of families and species found in American Samoa, Guam, and the U.S. Minor Outlying Islands follow the Clements taxonomy because the AOS does not address those areas.^[11]

Unless otherwise noted, the species listed here are considered to occur regularly in the United States as permanent residents, summer or winter residents or visitors, or annual migrants. The following tags are used to designate some species:

• (A) Accidental - occurrence based on one or two (rarely more) records and unlikely to occur regularly
• (C) Casual - occurrence based on two or a few records, with subsequent records not improbable
• (E) Extinct - a species which no longer exists
• (Ex) Extirpated - a species which no longer occurs in the United States, but other populations still exist elsewhere
• (I) Introduced - a species established solely as result of direct or indirect human intervention; synonymous with non-native and non-indigenous
• (EH) Endemic to Hawaii - a native species found only in Hawaii
• (EG) Endemic to Guam - a native species found only in Guam
• (ENM) Endemic to the Northern Mariana Islands - a native species found only in the Northern Mariana Islands
• (EP) Endemic to Puerto Rico - a native species found only in Puerto Rico
• (EU) Endemic to the U.S. Minor Outlying Islands - a native species found only in the U.S. Minor Outlying Islands
• (EM) Endemic to the mainland - a native species found only in the 48 contiguous states, Alaska, and their adjacent islands

The (A) and (C) tags correspond to the codes 5 and 4 respectively of the American Birding Association.^[12] The (E), (Ex), and (I) tags describe species' status according to the AOS. The (EH) tags follow the AOS list and the (EM) tags are based on the Clements taxonomy.

Population status symbols are those of the Red List published by the International Union for Conservation of Nature (IUCN).^[13] The symbols apply to the species' worldwide status, not their status solely in the United States except for endemic species. The symbols and their meanings, in increasing order of peril, are:

LC = least concern NT = near threatened VU = vulnerable EN = endangered CR = critically endangered EW = extinct in the wild EX = extinct

By the numbers[]

This list contains 1125 species found in the 50 states and the District of Columbia. Of these 1125, 155 are tagged as accidental, 101 as casual, and 55 as introduced. Thirty-three are known to be extinct and one, the thick-billed parrot, has been extirpated though a population remains in Mexico. Thirty-three living species are endemic to Hawaii; an additional 28 former Hawaiian endemics are known to be extinct and a few others are thought to be. Sixteen species are endemic to the 48 contiguous states and one to Alaska.

There are an additional 146 species whose presence in the United States is only within one or more U.S. territories; some of those species have become extinct. The total number of bird species on the list is 1267 (i.e. the 1120 bird species found in the 50 states and District of Columbia, plus the 146 species found only in the U.S. territories). Some of the species found in the 50 states and District of Columbia are also found in the U.S. territories.

Ducks, geese, and waterfowl[]

Order: Anseriformes   Family: Anatidae

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.

Megapodes[]

Hummingbirds[]

Order: Apodiformes   Family: 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: Gruiformes   Family: 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.

Finfoots[]

Order: Gruiformes   Family: Heliornithidae

Finfoots resemble rails; they have long necks, slender bodies, broad tails, and sharp, pointed bills. Their legs and feet are brightly colored. The family has three species and only the sungrebe is found in the New World.

• Sungrebe, Heliornis fulica (A) LC

Limpkin[]

Order: Gruiformes   Family: Aramidae

They are medium to large waders with strong black or yellow-black bills, large yellow eyes, and cryptic plumage. Despite being classed as waders, most species have a preference for arid or semi-arid habitats.

• Double-striped thick-knee, Burhinus bistriatus (A) LC

Stilts and avocets[]

Order: Charadriiformes   Family: 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.

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: Charadriiformes   Family: Glareolidae

The 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. Their flight is fast and graceful like that of a swallow or a tern, with many twists and turns to pursue their prey.

• Oriental pratincole, Glareola maldivarum (A) LC

Skuas and jaegers[]

Order: Charadriiformes   Family: Stercorariidae

Skuas 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.

Gulls, terns, and skimmers[]

Order: Charadriiformes   Family: Laridae

Laridae is a family of medium to large seabirds and includes gulls, terns, and skimmers. Gulls are typically gray or white, often with black markings on the head or wings. They have stout, longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with grey or white plumage, often with black markings on the head. Most terns hunt fish by diving but some pick insects off the surface of fresh water. Terns are generally long-lived birds, with several species known to live in excess of 30 years. Skimmers are a small family of tropical tern-like birds. They have an elongated lower mandible which they use to feed by flying low over the water surface and skimming the water for small fish.

Tropicbirds[]

Order: Phaethontiformes   Family: Phaethontidae

Monarch flycatchers[]

Order: Passeriformes   Family: Monarchidae

The Monarchinae are a relatively recent grouping of a number of seemingly very different birds, mostly from the Southern Hemisphere, which are more closely related than they at first appear. Many of the approximately 140 species making up the family were previously assigned to other groups, largely on the basis of general morphology or behavior. With the new insights generated by the DNA-DNA hybridisation studies of Sibley and his co-workers toward the end of the 20th century, however, it became clear that these apparently unrelated birds were all descended from a common ancestor. The Monarchinae are small to medium-sized insectivorous passerines, many of which hunt by flycatching.

Five of the species listed below (three species endemic to Hawaii, one species found in American Samoa, and one species endemic to the Northern Mariana Islands) represent the group in the United States. One species, the Guam flycatcher, is extinct because of the introduced brown tree snake on Guam.
