The list's taxonomic treatment (designation and sequence of orders, families, and species) and nomenclature (common and scientific names) are also those of the SACC.
[3] According to the SACC, the avifauna of Chile has 525 confirmed species, of which 12 are endemic, 128 are rare or vagrants, six have been introduced by humans, and one is extinct.
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.
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.
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.
Order: Nyctibiiformes Family: Nyctibiidae The potoos (sometimes called poor-me-ones) are large near passerine birds related to the nightjars and frogmouths.
Order: Apodiformes Family: Trochilidae Hummingbirds are small birds capable of hovering in mid-air due to the rapid flapping of their wings.
Order: Gruiformes Family: Aramidae The limpkin is an odd bird that looks like a large rail, but is skeletally closer to the cranes.
Order: Charadriiformes Family: Haematopodidae The oystercatchers are large and noisy plover-like birds, with strong bills used for smashing or prising open molluscs.
Order: Charadriiformes Family: Pluvianellidae The Magellanic plover is a rare wader found only in southernmost South America.
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.
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.
Order: Charadriiformes Family: Rostratulidae Painted-snipes are short-legged, long-billed birds similar in shape to the true snipes, but more brightly colored.
Terns are a group of generally medium to large seabirds typically with gray or white plumage, often with black markings on the head.
Order: Phaethontiformes Family: Phaethontidae Tropicbirds are slender white birds of tropical oceans, with exceptionally long central tail feathers.
Order: Sphenisciformes Family: Spheniscidae The penguins are a group of aquatic, flightless birds living almost exclusively in the Southern Hemisphere.
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.
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.
Order: Ciconiiformes Family: Ciconiidae Storks are large, long-legged, long-necked, wading birds with long, stout bills.
Order: Pelecaniformes Family: Pelecanidae Pelicans are large water birds with a distinctive pouch under their beak.
Unlike other long-neeecked birds such as storks, ibises, and spoonbills, members of Ardeidae fly with their necks retracted.
Order: Strigiformes Family: Strigidae The typical owls are small to large solitary nocturnal birds of prey.
Order: Coraciiformes Family: Alcedinidae Kingfishers are medium-sized birds with large heads, long pointed bills, short legs, and stubby tails.
Order: Piciformes Family: Picidae Woodpeckers are small to medium-sized birds with chisel-like beaks, short legs, stiff tails and long tongues used for capturing insects.
Order: Psittaciformes Family: Psittacidae Parrots are small to large birds with a characteristic curved beak.
Comparatively little is known about this diverse group, although all have broad bills with hooked tips, rounded wings and strong legs.
Order: Passeriformes Family: Tyrannidae Tyrant flycatchers are passerine birds which occur throughout North and South America.
Order: Passeriformes Family: Parulidae The wood-warblers are a group of small, often colorful, passerine birds restricted to the New World.
Order: Passeriformes Family: Thraupidae The tanagers are a large group of small to medium-sized passerine birds restricted to the New World, mainly in the tropics.
As a family they are omnivorous, but individual species specialize in eating fruits, seeds, insects, or other types of food.
