The sharp-shinned hawk is a small hawk, with males being the smallest hawks in the United States and Canada, but with the species averaging larger than some Neotropical species, such as the tiny hawk. The taxonomy is far from resolved, with some authorities considering the southern taxa to represent three separate species: white-breasted hawk, plain-breasted hawk, and rufous-thighed hawk. The American Ornithological Society keeps all four variations conspecific.
The black-headed duck is a South American duck allied to the stiff-tailed ducks in the tribe Oxyurini of the family Anatidae. It is the only member of the genus Heteronetta.
The thick-billed flowerpecker is a tiny bird in the flowerpecker group. They feed predominantly on fruits and are active birds that are mainly seen in the tops of trees in forests. It is a resident bird with a wide distribution across tropical southern Asia from India east to Indonesia and Timor with several populations recognized as subspecies some of which are sometimes treated as full species.
The fulvous whistling duck or fulvous tree duck is a species of whistling duck that breeds across the world's tropical regions in much of Mexico and South America, the West Indies, the southern United States, sub-Saharan Africa and the Indian subcontinent. It has plumage that is mainly reddish brown, long legs and a long grey bill, and shows a distinctive white band across its black tail in flight. Like other members of its ancient lineage, it has a whistling call which is given in flight or on the ground. Its preferred habitat consists of wetlands with plentiful vegetation, including shallow lakes and paddy fields. The nest, built from plant material and unlined, is placed among dense vegetation or in a tree hole. The typical clutch is around ten whitish eggs. The breeding adults, which pair for life, take turns to incubate, and the eggs hatch in 24–29 days. The downy grey ducklings leave the nest within a day or so of hatching, but the parents continue to protect them until they fledge around nine weeks later.
The barred antshrike is a passerine bird in the antbird family. It is found in the Neotropics from Tamaulipas, Mexico, through Central America, Trinidad and Tobago, and a large part of South America east of the Andes as far south as northern Argentina, Bolivia and Paraguay. There is one accepted record from southern Texas. It is found in a wide range of wooded habitats in both humid and arid regions. Throughout a large part of its range, it is among the most common antbirds.
The crested duck or South American crested duck is a species of duck native to South America, the belonging to the monotypic genus Lophonetta. It is sometimes included in Anas, but it belongs to a South American clade that diverged early in dabbling duck evolution. There are two subspecies: L. specularioides alticola and L. specularioides specularioides. The Patagonian crested duck is also called the southern crested duck and its range lies in the Falklands, Chile, and Argentina.
The dot-winged antwren is a passerine bird in the antbird family. In the past it was sometimes known as the velvety antwren, and some of its more distinctive subspecies have their own infrequently used English names. It is a resident in tropical Central and South America from southeastern Mexico south to western Ecuador, northern Bolivia, central Brazil and the Guianas. It is the only member of the genus Microrhopias.
The Papuan harrier is a bird of prey native to New Guinea which belongs to the harrier genus Circus. It was classified as a subspecies of the eastern marsh harrier of eastern Asia.
The bar-throated apalis is a small African passerine bird belonging to the genus Apalis of the family Cisticolidae. It is native to the eastern and southern Afrotropics.
The southern tchagra is a passerine bird found in dense scrub and coastal bush in southern and south-eastern South Africa and Swaziland.
The plaintive cuckoo is a species of bird belonging to the genus Cacomantis in the cuckoo family Cuculidae. It is native to Asia, from India, Nepal and China to Indonesia.
The oasis hummingbird is a species of hummingbird in tribe Mellisugini of subfamily Trochilinae, the "bee hummingbirds". It is the only species placed in the genus Rhodopis. It is found in Chile and Peru
The bicolored hawk is a species of bird of prey in the family Accipitridae. It is found in forest, woodland, second growth, plantations, and wooded savanna in southeastern Mexico, Central America, and northern and central South America. Though generally uncommon, it is the most common species of Accipiter in most of its range, but it does not occur at altitudes above 2,700 metres (8,900 ft) such as the highest parts of the Andes.
The Pacific pygmy owl or Peruvian pygmy owl is a small "typical owl" in subfamily Surniinae. It is found in Chile, Ecuador, and Peru.
The black-winged ground dove is a species of bird in the family Columbidae. It is found in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru.
The variable antshrike is a species of bird in the family Thamnophilidae found widely in South America. It is, as its common name suggests, arguably the species of antbird with the most variable plumage.
The Guayaquil squirrel is a tree squirrel endemic to Ecuador and Peru. It is a robust squirrel with a head-and-body length of 18 to 32 cm and a similar length tail. The colour is variable; in Peru, a pale morph is more common, while in Ecuador, most individuals have darker grey fur on the forequarters, dull orange hindquarters. A melanistic morph is sometimes seen. It lives largely in trees and is diurnal, feeding on seeds, flowers, and other plant material, fungi and some insects. These squirrels are also found in urban areas, living in close proximity to humans, and may be vectors for leptospirosis and Chagas disease. This squirrel faces no particular threats, has a wide range and is relatively common, and the International Union for Conservation of Nature has rated it as being of "least concern".
The Oriental cuckoo or Horsfields cuckoo is a bird belonging to the genus Cuculus in the cuckoo family Cuculidae. It was formerly classified as a subspecies of the Himalayan cuckoo, with the name 'Oriental cuckoo' used for the combined species. Differences in voice and size suggest that it should be treated as a separate species. The binomial name Cuculus horsfieldi has often been used instead of Cuculus optatus, but is now usually considered to be a junior synonym.
The black-fronted bushshrike is a passerine bird of the bushshrike family, Malaconotidae. It inhabits forests mainly in East Africa. It forms a superspecies with the many-colored bushshrike and the two are sometimes considered to be a single species.
The Chilean pintail, also known as the golden peck duck or brown pintail, is a subspecies of the yellow-billed pintail, a duck in the dabbling duck subfamily Anatinae. Its local names are pato jergón grande, pato maicero and pato piquidorado in Spanish, and marreca-parda or marreca-danada in Portuguese.
