List of birds of Virginia

This list of birds of Virginia includes species credibly documented in the U.S. state of Virginia by the Virginia Avian Records Committee of the Virginia Society of Ornithology (VARCOM). As of January 1, 2022 the list contained 487 species and four species pairs.[1] Of them, 109 are considered accidental. Seven species were introduced to North America, one is extinct, and one has been extirpated. Four additional species, now extinct, are believed to have occurred in Virginia, but there is insufficient evidence to include them in the main list. The published list includes identifiable subspecies which are not presented here. An additional extirpated species is added from another source. Additional accidental species have also been added from different sources.

The northern cardinal is the state bird of Virginia.

This list is presented in the taxonomic sequence of the Check-list of North and Middle American Birds, 7th edition through the 62nd 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.

Unless otherwise noted, all species listed below are considered to occur regularly in Virginia as permanent residents, summer or winter visitors, or migrants. The following codes are used to annotate some species:

  • (A) - Accidental - a species that has "less than six accepted physical or written records in the past 50 years" according to VARCOM
  • (R) - Rare - "A species that is so scarce that it cannot be expected with any certainty, or one that occurs in a very specific and extremely limited habitat" according to VARCOM
  • (I) - Introduced - a species introduced to North America by humans
  • (H) - Historical - "Species believed to have occurred historically" according to VARCOM

Ducks, geese, and waterfowl

edit
 
Wood ducks
 
Mallards
 
Northern shoveler
 
Hooded merganser

Order: Anseriformes   Family: 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. Forty-eight species have been recorded in Virginia.

New World quail

edit

Order: Galliformes   Family: 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. One species has been recorded in Virginia.

Pheasants, grouse, and allies

edit
 
Ruffed grouse

Order: Galliformes   Family: Phasianidae

Phasianidae consists of the pheasants and their allies. 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. Turkeys have a distinctive fleshy wattle that hangs from the underside of the beak and a fleshy protuberance that hangs from the top of its beak called a snood. As with many galliform species, the female (the hen) is smaller and much less colorful than the male (the tom). With wingspans of 1.5–1.8 meters (almost 6 feet), the turkeys are the largest birds in the open forests in which they live and are rarely mistaken for any other species. One species has been recorded in Virginia. Grouse inhabit temperate and subarctic regions of the Northern Hemisphere. They are game and are sometimes hunted for food. In all Virginia species, males are polygamous and have elaborate courtship displays. These heavily built birds have legs feathered to the toes. Most species are year-round residents and do not migrate. Four species have been recorded in Virginia.

Flamingoes

edit

Order: Phoenicopteriformes   Family: Phoenicopteridae

Flamingoes are gregarious wading birds, usually 3 to 5 feet (0.9 to 1.5 m) tall, found in both the Western and Eastern Hemispheres. Flamingos filter-feed on shellfish and algae. Their oddly shaped beaks are adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down. One species has been recorded in Virginia.

Grebes

edit
 
Pied-billed grebe

Order: Podicipediformes   Family: 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. Six species have been recorded in Virginia.

Pigeons and doves

edit
 
Mourning dove

Order: Columbiformes   Family: Columbidae

Pigeons and doves are stout-bodied birds with short necks and short slender bills with a fleshy cere. Six species have been positively recorded in Virginia.

Cuckoos

edit
 
Black-billed cuckoo

Order: Cuculiformes   Family: 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. Three species have been recorded in Virginia.

Nightjars and allies

edit
 
Common nighthawk

Order: Caprimulgiformes   Family: 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 which are of little use for walking and long, pointed wings. Their soft plumage is cryptically colored to resemble bark or leaves. Three species have been recorded in Virginia.

Swifts

edit

Order: Apodiformes   Family: 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. One species has been recorded in Virginia.

Hummingbirds

edit
 
Ruby-throated hummingbird

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. Nine species have been recorded in Virginia.

Rails, gallinules, and coots

edit
 
Virginia rail

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. Ten species have been recorded in Virginia.

Limpkin

edit

Order: Gruiformes   Family: Aramidae

The limpkin is a large bird in a monotypic family. It is similar in appearance to the rails, but skeletally it is closer to the cranes. It is found in marshes and gets its common name from its appearance of limping as it walks.

Cranes

edit

Order: Gruiformes   Family: Gruidae

Cranes are large, long-legged, and 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". One species has been recorded in Virginia.

Stilts and avocets

edit

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. Two species have been recorded in Virginia.

Oystercatchers

edit
 
American oystercatcher

Order: Charadriiformes   Family: Haematopodidae

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. Thirty-eight species have been positively recorded in Virginia.

Skuas and jaegers

edit
 
Pomarine jaeger

Order: Charadriiformes   Family: Stercorariidae

They 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. Five species have been recorded in Virginia.

Auks, murres, and puffins

edit

Order: Charadriiformes   Family: 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. Seven species have been recorded in Virginia.

Gulls, terns, and skimmers

edit
 
Laughing gull
 
Ring-billed gull
 
Royal tern

Order: Charadriiformes   Family: Laridae

Gulls are typically medium to large birds, usually gray or white, often with black markings on the head or wings. They have stout, stout, longish bills and webbed feet. The large species take up to four years to attain full adult plumage, but two years is typical for small gulls. Terns are in general medium to large birds, typically with gray or white plumage, often with black markings on the head. They have longish bills and webbed feet. They are lighter bodied and more streamlined than gulls and look elegant in flight with long tails and long narrow wings. Skimmers are tropical and subtropical species. They have an elongated lower mandible. They feed by flying low over the water surface with the lower mandible skimming the water for small fish. Thirty-four species have been recorded in Virginia.

Tropicbirds

edit

Order: Phaethontiformes   Family: 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. Two species have been recorded in Virginia.

Loons

edit
 
Common loon

Order: Gaviiformes   Family: 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. Three species have been recorded in Virginia.

Albatrosses

edit

Order: Procellariiformes   Family: 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. Two species have been recorded in Virginia.

Southern storm-petrels

edit

Order: Procellariiformes   Family: 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

edit
 
Leach's storm-petrel

Order: Procellariiformes   Family: 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

edit
 
Sooty shearwater

Order: Procellariiformes   Family: 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. Eleven species have been recorded in Virginia.

Storks

edit

Order: Ciconiiformes   Family: Ciconiidae

Storks are large, heavy, long-legged, long-necked wading birds with long stout bills and wide wingspans.

Frigatebirds

edit

Order: Suliformes   Family: 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. One species has been recorded in Virginia.

New World vultures

edit
 
Turkey vulture

Order: Accipitriformes   Family: 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. Two species have been recorded in Virginia.

Osprey

edit

Order: Accipitriformes   Family: Pandionidae
