This is a list of the bird species recorded in the Cayman Islands. The avifauna of the Cayman Islands included a total of 270 species, according to Bird Checklists of the World as of May 2023.[1] Of them, 163 are rare or accidental and eight are introduced. One species (Grand Cayman thrush) was endemic to the islands but is now extinct, and one species (Jamaican oriole) has been extirpated.[2]BirdLife International has reclassified Grand Cayman's endemic Cuban bullfinch subspecies as a full species, the Grand Cayman bullfinch, but the AOS has not yet accepted this. In addition, the islands hold most of the world population of vitelline warbler which otherwise occurs only on the Swan Islands of Honduras.[2] There are 17 endemic subspecies belonging to 14 different species.[2]
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).[3] 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 the Cayman Islands
(E) Endemic - a species endemic to the Cayman Islands
(I) Introduced - a species introduced by humans either directly to the Cayman Islands or elsewhere in the New World
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 an oily coating.
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.
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 camouflaged to resemble bark or leaves.
The potoos (sometimes called poor-me-ones) 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 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. Typically they inhabit 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.
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.
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.
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. Variation in length of legs and bills enables 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 grey 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 grey 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 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.
The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium septum and a long outer functional primary.
Frigatebirds are large seabirds usually found over tropical oceans. They are large, black-and-white, or completely black, with long wings and deeply forked tails. The males have coloured 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.
Anhingas are often called "snake-birds" because of their long thin neck, which gives a snake-like appearance when they swim with their bodies submerged. The males have black and dark-brown plumage, an erectile crest on the nape, and a larger bill than the female. The females have much paler plumage especially on the neck and underparts. The darters have completely webbed feet and their legs are short and set far back on the body. Their plumage is somewhat permeable, like that of cormorants, and they spread their wings to dry after diving.
Phalacrocoracidae is a family of medium to large coastal, fish-eating seabirds that includes cormorants and shags. Plumage colouration varies, with the majority having mainly dark plumage, some species being black-and-white, and a few being colourful.
Pelicans are large water birds with a distinctive pouch under their beak. As with other members of the order Pelecaniformes, they have webbed feet with four 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 wary. 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 despite their size and weight, very capable soarers.
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 carrion.
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 powerful hooked beaks for tearing flesh from their prey, strong legs, powerful talons, and keen eyesight.
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.
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.
Parrots are small to large birds with a characteristic curved beak. Their upper mandibles have slight mobility in the joint with the skull and they have a generally erect stance. All parrots are zygodactyl, having the four toes on each foot placed two at the front and two to the back.
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, have plain colouring. As the name implies, most are insectivorous.
The vireos are a group of small to medium-sized passerine birds. They are typically greenish in colour 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 kinglets and "crests" are a small family of birds which resemble some warblers. They are very small insectivorous birds in the single genus Regulus. The adults have coloured crowns, giving rise to their name.
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.
These dainty birds resemble Old World warblers in their build and habits, moving restlessly through the foliage seeking insects. The gnatcatchers and gnatwrens are mainly soft bluish grey in colour and have the typical insectivore's long sharp bill. They are birds of fairly open woodland or scrub, which nest in bushes or trees.
The mimids are a family of passerine birds that includes thrashers, mockingbirds, tremblers, and the New World catbirds. These birds are notable for their vocalizations, especially their ability to mimic a wide variety of birds and other sounds heard outdoors. Their colouring tends towards dull-greys and browns.
Starlings are small to medium-sized passerine birds. Their flight is strong and direct and they are very gregarious. Their preferred habitat is fairly open country. They eat insects and fruit. Plumage is typically dark with a metallic sheen.
The thrushes are a group of passerine birds that occur mainly 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.
The estrildid finches are small passerine birds native to the Old World tropics. 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 colours and patterns.
Old World sparrows are small passerine birds. In general, sparrows tend to be small plump brownish or greyish birds with short tails and short powerful beaks. Sparrows are seed eaters, but they also consume small insects.
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 (family Thraupidae) but were placed in their own family in 2017.
This species was historically placed in the New World warblers (Parulidae) but nonetheless most authorities were unsure if it belonged there. It was placed in its own family in 2017.
The icterids are a group of small to medium-sized, often colourful, passerine birds restricted to the New World and include the grackles, New World blackbirds, and New World orioles. Most species have black as the predominant plumage colour, often enlivened by yellow, orange, or red.
The New World warblers are a group of small, often colourful, passerine birds restricted to the New World. Most are arboreal, but some are 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 coloured. As a family they are omnivorous, but individual species specialize in eating fruits, seeds, insects, or other types of food. Most have short, rounded wings.
