This is a list of the bird species recorded in the archipelago of Puerto Rico, which consists of the main island of Puerto Rico, two island municipalities off the east coast (Vieques and Culebra), three uninhabited islands off the west coast (Mona, Monito and Desecheo) and more than 125 smaller cays and islands.
The avifauna of Puerto Rico included a total of 385 species as of July 2022, according to Bird Checklists of the World.[1] Of them, 201 are accidental, two have been extirpated, and one is believed to be extinct. Seventeen species are endemic. Non-native species are common; 43 listed here were introduced by humans. Individuals of many other species (mostly parrots, finches, and waxbills) are flying free, presumably after escaping or being released from captivity.[2] For example, a 2018 study on introduced Psittacidae on the island found at least 46 species present, of which 24% are only found in the pet trade (captivity), 48% have been observed in the wild (but are not known to be breeding), and 28% are established (naturalized) and know to have bred or are currently breeding.[3] Around 120 species breed in Puerto Rico while the majority of the others overwinter in the archipelago. An additional accidental species has been 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 63rd Supplement, published by the American Ornithological Society (AOS).[4] 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 tags have been used to highlight several categories of occurrence:
(A) Accidental - a species that rarely or accidentally occurs in Puerto Rico
(E) Endemic - a species endemic to Puerto Rico
(Ex) Extirpated - a species that no longer occurs in Puerto Rico although populations exist elsewhere
(I) Introduced - a species introduced to Puerto Rico as a consequence, direct or indirect, of human actions
The Anatidae include 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.
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.
Flamingos 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 specially adapted to separate mud and silt from the food they consume and, uniquely, are used upside-down.
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.
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 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 are a group of large near passerine birds related to the nightjars and frogmouths. These are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars.
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.
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.
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.
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.
The jacanas are a group 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.
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.
The family Stercorariidae are, in general, medium to large birds, typically with gray or brown plumage, often with white markings on the wings. They nest on the ground in temperate and arctic regions and are long-distance migrants.
Laridae is a family of medium to large seabirds and includes gulls, kittiwakes, terns, and skimmers. They are typically gray or white, often with black markings on the head or wings. They have longish bills and webbed feet. Terns are a group of generally medium to large seabirds typically with gray 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 flying low over the water surface and skimming the water for small fish.
Tropicbirds are slender white birds of tropical oceans with exceptionally long central tail feathers. Their long wings have black markings, as does the head.
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 species were included with the other storm-petrels in 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.
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 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 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.
Phalacrocoracidae is a family of medium to large coastal, fish-eating seabirds that includes cormorants and shags. Plumage coloration is varied with the majority having mainly dark plumage, some species being black-and-white, and a few being quite colorful.
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.
The family Ardeidae contains the bitterns, herons, and egrets. 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.
Threskiornithidae is a family of large terrestrial and wading birds which includes the ibises and spoonbills. They have long, broad wings with 11 primary and about 20 secondary feathers. They are strong fliers and, rather surprisingly, given their size and weight, very capable soarers.
The turkey vulture (whose origin in the archipelago is unclear and may be an introduced species[10]) has taken residence in Southwestern Puerto Rico, most notably in the Guánica State Forest.
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.
The family Pandionidae contains only one species, the osprey. The osprey is a medium-large raptor which is a specialist fish-eater with a worldwide distribution.
Accipitridae is a family of birds of prey, which includes hawks, eagles, kites, harriers, and Old World vultures. These birds have very large powerful hooked beaks for tearing flesh from their prey, strong legs, powerful talons, and keen eyesight.
Short-eared owl, a species found in the southwestern municipality of Cabo Rojo.Puerto Rican owl, a species found in the western municipality of Aguada.
The typical owls are small to large solitary nocturnal birds of prey. They have large forward-facing eyes and ears, a hawk-like beak, and a conspicuous circle of feathers around each eye called a facial disk.
Todies are a group of small near passerine forest species endemic to the Caribbean. These birds have colorful plumage and resemble kingfishers, but have flattened bills with serrated edges. They eat small prey such as insects and lizards.
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.
The cockatoos share many features with other parrots including the characteristic curved beak shape and a zygodactyl foot, with two forward toes and two backwards toes. They differ, however in a number of characteristics, including the often spectacular movable headcrest.
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 8 cm (3.1 in) to 1 m (3.3 ft) in length. Most of the more than 150 species in this family are found in the New World.
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.
The vireos are a group of small to medium-sized passerine birds. They are typically greenish in color and resemble New World warblers apart from their heavier bills.
The family Hirundinidae is adapted to aerial feeding. They have a slender streamlined body, long pointed wings, and a short bill with a wide gape. The feet are adapted to perching rather than walking, and the front toes are partially joined at the base.
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.
The mimids are a family of passerine birds that includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalization, especially their remarkable ability to mimic a wide variety of birds and other sounds heard outdoors. The species tend towards dull grays and browns in their appearance.
Starlings and mynas are small to medium-sized Old World passerine birds with strong feet. Their flight is strong and direct and they are very gregarious. Their preferred habitat is fairly open country, and they eat insects and fruit. Plumage is typically dark with a metallic sheen.
The Thrushes are a group of passerine birds that occur mainly but not exclusively in the Old World. They are plump, soft plumaged, small to medium-sized insectivores or sometimes omnivores, often feeding on the ground. Many have attractive songs.
Old World flycatchers are a large group of small passerine birds native to the Old World. They are mainly small arboreal insectivores. The appearance of these birds is highly varied, but they mostly have weak songs and harsh calls.
Weavers are a group of small passerine birds related to the finches. These are seed-eating birds with rounded conical bills, most of which breed in sub-Saharan Africa, with fewer species in tropical Asia. Weavers get their name from the large woven nests many species make. They are gregarious birds which often breed colonially.
The Viduidae is a family of small passerine birds native to Africa that includes indigobirds and whydahs. All species are brood parasites which lay their eggs in the nests of estrildid finches. Species usually have black or indigo predominating in their plumage.
The estrildid finches are small passerine birds of the Old World tropics and Australasia. They are gregarious and often colonial seed eaters with short thick but pointed bills. They are all similar in structure and habits, but have wide variation in plumage colors and patterns.
Sparrows are small passerine birds. In general, sparrows tend to be small plump brownish or grayish birds with short tails and short powerful beaks. Sparrows are seed eaters, but they also consume small insects.
Finches are seed-eating passerine birds, that are small to moderately large and have a strong beak, usually conical and in some species very large. All have twelve tail feathers and nine primaries. These birds have a bouncing flight with alternating bouts of flapping and gliding on closed wings, and most sing well.
Until 2017, these species were considered part of the family Emberizidae. Most of the species are known as sparrows, but these birds are not closely related to the Old World sparrows which are in the family Passeridae. Many of these have distinctive head patterns.
The members of this small family are native to the Greater Antilles. They were formerly classified as tanagers but were placed in their own family in 2017.
The icterids are a group of small to medium-sized, often colorful passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red.
The wood-warblers are a group of small often colorful passerine birds restricted to the New World. Most are arboreal, but some are more terrestrial. Most members of this family are insectivores.
The cardinals are a family of robust, seed-eating birds with strong bills. They are typically associated with open woodland. The sexes usually have distinct plumages.
The tanagers are a large group of small to medium-sized passerine birds restricted to the New World, mainly in the tropics. Many species are brightly colored. As a family they are omnivorous, but individual species specialize in eating fruits, seeds, insects, or other types of food.
