List of birds of Florida


This list of birds of Florida includes species documented in the U.S. state of Florida and accepted by the Florida Ornithological Society Records Committee. As of November 2022, there were 539 species included in the official list. Of them, 168 species and eight identifiable subspecies are classed as accidental, 18 have been introduced to North America, four are extinct, and one has been extirpated. More than 100 "verifiable...exotic species found free-flying in the wild" according to the FOSRC. Additional accidental, extirpated and recently extinct species have been added from other sources. Four hypothetical species have been also added from another source.
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. 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.
The following status codes have been used to annotate some species:
  • Accidental – a species that occurs rarely or accidentally in Florida, and for which the FOSRC requests a full report for verification
  • Introduced – a species that has been introduced to North America by the actions of humans, either directly or indirectly, and has become established in Florida
  • Extinct – a recent bird that no longer exists
  • Extirpated – a species that is no longer in Florida, but exists elsewhere

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, flattened bills, and feathers that are excellent at shedding water due to special oils.

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
The Phasianidae is the family containing the pheasants and their allies. These are terrestrial birds, variable in size but generally plump, with broad, relatively short wings. Many are gamebirds or have been domesticated as a food source for humans.

Flamingoes

Order: PhoenicopteriformesFamily: Phoenicopteridae
Flamingoes are gregarious wading birds, usually 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.

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.

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.

Potoos

Order: NyctibiiformesFamily: Nyctibiidae
The potoos are large near passerine birds related to the nightjars and frogmouths. They are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars.

Swifts

Order: ApodiformesFamily: Apodidae
The swifts are small birds, spending most of their lives flying. They have very short legs and never settle voluntarily on the ground, perching instead only on vertical surfaces. Many swifts have very 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
The 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, making them difficult to observe. Most have strong legs with long toes, short rounded wings, and are weak fliers.

Limpkin

Order: GruiformesFamily: Aramidae
The limpkin is an odd bird that looks like a large rail, but is skeletally closer to the cranes. It is found in marshes with some trees or scrub in the Caribbean, South America, and southern Florida.

Cranes

Order: GruiformesFamily: Gruidae
Cranes are large, tall birds with long legs and long necks. Unlike the similar-looking but un-related herons, cranes fly with necks extended. Most have elaborate and noisy courtship displays or "dances". When in a group, they may also "dance" for no particular reason, jumping up and down in an elegant manner, seemingly just for pleasure or to attract a mate.

Thick-knees

Order: CharadriiformesFamily: Burhinidae
The thick-knees are a group of largely tropical waders in the family Burhinidae. They are found worldwide within the tropical zone, with some species also breeding in temperate Europe and Australia. 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.

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, conspicuous, and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.

Lapwings and plovers

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 generally found in open country, mostly in habitats near water.

Jacanas

Order: CharadriiformesFamily: Jacanidae
The jacanas are a family of waders found worldwide within the tropical zone. They are identifiable by their huge feet and claws which enable them to walk on floating vegetation in the shallow lakes that are their preferred habitat.

Sandpipers and allies

Order: CharadriiformesFamily: Scolopacidae
Scolopacidae is a large and diverse family of small to medium-sized shorebirds which includes the sandpipers, curlews, godwits, shanks, tattlers, woodcocks, snipes, dowitchers, and phalaropes. Most eat small invertebrates picked out of the mud or sand. 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
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.

Skuas and jaegers

Order: CharadriiformesFamily: Stercorariidae
Skuas are medium to large seabirds, 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 not closely related to penguins and are able to fly. Auks live on the open sea, only deliberately coming ashore to breed.

Gulls, terns, and skimmers

Order: CharadriiformesFamily: Laridae
The Laridae are a family of medium to large seabirds and containing the 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, because their legs are placed towards the rear of the body, are clumsy on land.

Albatrosses

Order: ProcellariiformesFamily: Diomedeidae
Albatrosses are among 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 tubular nostrils with a median septum.

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, also known as darters or snakebirds, are cormorant-like water birds with long necks and long, straight beaks. They are fish eaters, diving for long periods, and often swim with only their neck above the water, looking rather like a water snake.

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 wading birds with long necks and legs. Herons are large and egrets are smaller. The cattle egret or "cow bird" is seen amongst flocks of cattle, for instance in ranches north of the Everglades. A bird will often attach itself to a particular bull, cow or calf, even being tolerated perching on the back or even the head of the animal. The birds are more shy than the animals, and will fly away if approached. The birds feed on various items turned over by the cattle as they graze and tramp the ground. Bitterns tend to be shorter necked and more secretive. Unlike other long-necked birds such as storks, ibises, and spoonbills, members of the Ardeidae fly with their necks pulled back into a curve.

Ibises and spoonbills

Order: PelecaniformesFamily: Threskiornithidae
The family Threskiornithidae includes the ibises and spoonbills. They have long, broad wings. Their bodies are elongated, the neck more so, with long legs. The bill is also long, curved downward in the ibises, straight and markedly flattened in the spoonbills.

New World vultures

Order: CathartiformesFamily: Cathartidae
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. Unlike Old World vultures, which find carcasses by sight, New World vultures have a good sense of smell with which they locate carcasses. The turkey vulture has a red head. The black vulture has a grey head. Although not a water bird, a flock of black vultures at the Myakka River State Park, southeast of Sarasota, has been seen bathing at the edge of the lake and then drying out their wings in the same way as cormorants like the Florida anhinga. This habit may help free them of parasites.

Osprey

Order: AccipitriformesFamily: Pandionidae
Pandionidae is a family of fish-eating birds of prey possessing a very large, powerful hooked beak for tearing flesh from their prey, strong legs, powerful talons, and keen eyesight. The family is monotypic.

Trogons

Order: TrogoniformesFamily: Trogonidae
The family Trogonidae includes trogons and quetzals. Found in tropical woodlands worldwide, they feed on insects and fruit, and their broad bills and weak legs reflect their diet and arboreal habits. Although their flight is fast, they are reluctant to fly any distance. Trogons have soft, often colorful, feathers with distinctive male and female plumage.

Kingfishers

Order: CoraciiformesFamily: Alcedinidae
Kingfishers are medium-sized birds with large heads, long pointed bills, short legs, and stubby tails.

Jacamars

Order: PiciformesFamily: Galbulidae
The jacamars are near passerine birds from tropical South America, with a range that extends up to Mexico. They feed on insects caught on the wing, and are glossy, elegant birds with long bills and tails. In appearance and behavior they resemble the Old World bee-eaters, although they are more closely related to puffbirds.

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

Ovenbirds

Order: PasseriformesFamily: Furnariidae
Ovenbirds comprise a large family of small sub-oscine passerine bird species found in Central and South America. They are a diverse group of insectivores which gets its name from the elaborate "oven-like" clay nests built by some species, although others build stick nests or nest in tunnels or clefts in rock. The woodcreepers are brownish birds which maintain an upright vertical posture, supported by their stiff tail vanes. They feed mainly on insects taken from tree trunks.

Vireos, shrike-babblers, and erpornis

Order: PasseriformesFamily: Vireonidae
The vireos are a group of small to medium-sized passerines. They are typically greenish in color and resemble wood warblers apart from their heavier bills.
