This list's taxonomic treatment (designation and sequence of orders, families and species) and nomenclature (common and scientific names) follow the conventions of The Clements Checklist of Birds of the World, 2016 edition. The family accounts at the beginning of each heading reflect this taxonomy, as do the species counts found in each family account. Introduced and accidental species are included in the total counts for Uruguay. The list of species is that of the South American Classification Committee (SACC) of the American Ornithologists' Union. The taxonomy used by the SACC differs from "Clements", and significant in names differences are noted. Differences from "Clements" in the sequence of orders, families, and species within families are not noted.
The following tags have been used to highlight certain categories, but not all species fall into one of these categories. Those that do not are commonly occurring native species.
Rheas
Order: Struthioniformes Family: Rheidae
The rheas are large flightless birds native to South America. Their feet have three toes rather than four which allows them to run faster. One species has been recorded in Uruguay.
Tinamous
Order: Tinamiformes Family: Tinamidae
The tinamous are one of the most ancient groups of bird. Although they look similar to other ground-dwelling birds like quail and grouse, they have no close relatives and are classified as a single family, Tinamidae, within their own order, the Tinamiformes. They are distantly related to the ratites (order Struthioniformes), that includes the rheas, emus, and kiwis. Three species have been recorded in Uruguay.
Screamers
Order: Anseriformes Family: Anhimidae
The screamers are a small family of birds related to the ducks. They are large, bulky birds, with a small downy head, long legs and large feet which are only partially webbed. They have large spurs on their wings which are used in fights over mates and in territorial disputes. Eight species have been recorded in Uruguay.
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, flattened bills, and feathers that are excellent at shedding water due to an oily coating. Twenty-one species have been recorded in Uruguay.
Guans, chachalacas, and curassows
Order: Galliformes Family: Cracidae
The Cracidae are large birds, similar in general appearance to turkeys. The guans and curassows live in trees, but the smaller chachalacas are found in more open scrubby habitats. They are generally dull-plumaged, but the curassows and some guans have colourful facial ornaments. Two species have been recorded in Uruguay.
Grebes
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. Four species have been recorded in Uruguay.
Flamingos
Order: Phoenicopteriformes Family: Phoenicopteridae
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 are used upside-down. One species has been recorded in Uruguay.
Penguins
Order: Sphenisciformes Family: Spheniscidae
The penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere. Most penguins feed on krill, fish, squid and other forms of sealife caught while swimming underwater. Three species have been recorded in Uruguay.
Albatrosses
Order: Procellariiformes Family: Diomedeidae
The albatrosses are among the largest of flying birds, and the great albatrosses from the genus Diomedea have the largest wingspans of any extant birds. Seven species have been recorded in Uruguay.
Shearwaters and petrels
Order: Procellariiformes Family: Procellariidae
The procellariids are the main group of medium-sized "true petrels", characterised by united nostrils with medium septum and a long outer functional primary. Twenty-one species have been recorded in Uruguay.
Storm-petrels
Order: Procellariiformes Family: Hydrobatidae
The storm-petrels are relatives of the petrels and are the smallest seabirds. They feed on planktonic crustaceans and small fish picked from the surface, typically while hovering. The flight is fluttering and sometimes bat-like. Three species have been recorded in Uruguay.
Storks
Order: Ciconiiformes Family: Ciconiidae
Storks are large, long-legged, long-necked, wading birds with long, stout bills. Storks are mute, but bill-clattering is an important mode of communication at the nest. Their nests can be large and may be reused for many years. Many species are migratory. Three species have been recorded in Uruguay.
Frigatebirds
Order: Suliformes Family: Fregatidae
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. One species has been recorded in Uruguay.
Boobies and gannets
Order: Suliformes Family: Sulidae
The sulids comprise the gannets and boobies. Both groups are medium to large coastal seabirds that plunge-dive for fish. Three species have been recorded in Uruguay.
Cormorants and shags
Order: Suliformes Family: Phalacrocoracidae
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. Two species have been recorded in Uruguay.
Anhingas
Order: Suliformes Family: Anhingidae
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. One species has been recorded in Uruguay.
Herons, egrets, and bitterns
Order: Pelecaniformes Family: Ardeidae
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. Eleven species have been recorded in Uruguay.
Ibises and spoonbills
Order: Pelecaniformes Family: Threskiornithidae
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. Five species have been recorded in Uruguay.
New World vultures
Order: Cathartiformes 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 carrion. Three species have been recorded in Uruguay.
Osprey
Order: Accipitriformes Family: Pandionidae
The Pandionidae family contains only one species, the osprey. The osprey is a medium-large raptor which is a specialist fish-eater with a worldwide distribution.
Hawks, eagles, and kites

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. 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. Seventeen species have been recorded in Uruguay.
Limpkin
Order: Gruiformes Family: Aramidae
The limpkin resembles a large rail. It has drab-brown plumage and a greyer head and neck.
Sheathbills
Order: Charadriiformes Family: Chionididae

Jacanas
Order: Charadriiformes Family: Jacanidae
The jacanas are a group of tropical waders in the family Jacanidae. They are found throughout the tropics. 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. One species has been recorded in Uruguay.
Sandpipers and allies
Order: Charadriiformes Family: Scolopacidae
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. Twenty-one species have been recorded in Uruguay.
Skuas and jaegers
Order: Charadriiformes Family: Stercorariidae
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. Six species have been recorded in Uruguay.

(The SACC places swifts in their own order, Apodiformes)
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 Uruguay.
Hummingbirds
Order: Caprimulgiformes Family: Trochilidae
(The SACC places hummingbirds in their own order, Trochiliformes)
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. Six species have been recorded in Uruguay.
Trogons
Order: Trogoniformes Family: 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.

Ten species have been recorded in Uruguay.
Seriemas
Order: Cariamiformes Family: Cariamidae
The seriemas are terrestrial birds which run rather than fly (though they are able to fly for short distances). They have long legs, necks and tails, but only short wings, reflecting their way of life. They are brownish birds with short bills and erectile crests, found on fairly-dry open grasslands. One species has been recorded in Uruguay.
Falcons and caracaras
Order: Falconiformes Family: Falconidae
Falconidae is a family of diurnal birds of prey. They differ from hawks, eagles and kites in that they kill with their beaks instead of their talons. Seven species have been recorded in Uruguay.

Typical antbirds
Order: Passeriformes Family: Thamnophilidae
The antbirds are a large family of small passerine birds of subtropical and tropical Central and South America. They are forest birds which tend to feed on insects at or near the ground. A sizable minority of them specialize in following columns of army ants to eat small invertebrates that leave their hiding places to flee from the ants. Many species lack bright color; brown, black and white are the dominant tones. Three species have been recorded in Uruguay.
Gnateaters
Order: Passeriformes Family: Conopophagidae
The gnateaters are round, short-tailed and long-legged birds, which are closely related to the antbirds. One species has been recorded in Uruguay.
Ovenbirds and woodcreepers
Order: Passeriformes Family: 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. Thirty-five species have been recorded in Uruguay.
Tyrant flycatchers

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 coloring. As the name implies, most are insectivorous. Fifty-six species have been recorded in Uruguay.
Cotingas
Order: Passeriformes Family: Cotingidae
The cotingas are birds of forests or forest edges in tropical South America. Comparatively little is known about this diverse group, although all have broad bills with hooked tips, rounded wings and strong legs.
