The cattle tyrant (Machetornis rixosa) is a species of bird in the tyrant-flycatcher family Tyrannidae. It is the only member of the genus Machetornis. The relationships of this species and genus to other genera in the tyrant flycatchers are uncertain. It resembles Tyrannus flycatchers, but this may be the result of convergence. Three subspecies are recognised, the nominate race, M. r. flavigularis and M. r. obscurodorsalis, although the latter two less ↑

The tropical kingbird (Tyrannus melancholicus) is a large tyrant flycatcher. This bird breeds from southern Arizona and the lower Rio Grande Valley of Texas in the United States through Central America, South America as far as south as central Argentina and western Peru, and on Trinidad and Tobago. Birds from the northernmost and southern breeding areas migrate to warmer parts of the range after breeding. less ↑

The yellow-green vireo (Vireo flavoviridis) is a small passerine bird. It breeds from southern Texas (occasionally the Rio Grande Valley) in the United States and the western and eastern mountain ranges of northern Mexico (the Sierra Madre Occidental and Sierra Madre Oriental—also the Cordillera Neovolcanica) south to central Panama. It is migratory, wintering in the northern and eastern Andes and the western Amazon Basin. less ↑

The sand martin (Riparia riparia) or European sand martin, bank swallow in the Americas, and collared sand martin in the Indian Subcontinent, is a migratory passerine bird in the swallow family. It has a wide range in summer, embracing practically the whole of Europe and the Mediterranean countries, part of northern Asia and also North America. It winters in eastern and southern Africa, South America and the Indian Subcontinent. less ↑

The American cliff swallow (Petrochelidon pyrrhonota) is a member of the passerine bird family Hirundinidae consisting of both swallow and martin species. The scientific name is derived from Ancient Greek; Petrochelidon originates from the petros meaning "rock" and khelidon "swallow", pyrrhonota comes from purrhos meaning "flame-coloured" and -notos "-backed". less ↑

The house wren (Troglodytes aedon) is a very small songbird of the wren family, Troglodytidae. It occurs from Canada to southernmost South America, and is thus the most widely distributed bird in the Americas. It occurs in most suburban areas in its range and it is the single most common wren. Its taxonomy is highly complex and some subspecies groups are often considered separate species. less ↑

The great thrush (Turdus fuscater) is a species of bird in the family Turdidae. It is found in Bolivia, Colombia, Ecuador, Peru, and Venezuela. It is considered as the largest thrush in South America. The great thrush's size distinguishes it from the several other uniform slaty-colored thrushes in its range. It inhabits subtropical or tropical moist montane forests and high-altitude shrubland, but can also make use of degraded forest and urban areas. less ↑

The tropical mockingbird (Mimus gilvus) is a resident breeding bird from southern Mexico south to northern Brazil, and in the Lesser Antilles and other Caribbean islands. The birds in Panama and Trinidad may have been introduced. The northern mockingbird (M. polyglottos) is its closest living relative, but the critically endangered Socorro mockingbird (M. graysoni) is also much closer to these two than previously believed . less ↑

The rufous-collared sparrow or Andean sparrow (Zonotrichia capensis) is an American sparrow found in a wide range of habitats, often near humans, from the extreme south-east of Mexico to Tierra del Fuego, and on the island of Hispaniola. It is famous for its diverse vocalizations, which have been intensely studied since the 1970s, particularly by Paul Handford and Stephen C. Lougheed (UWO), Fernando Nottebohm (Rockefeller University) and Pablo Luis Tubaro (UBA). Local names f less ↑

The blackpoll warbler (Setophaga striata) is a New World warbler. Breeding males are mostly black and white. They have a prominent black cap, white cheeks and white wing bars. The blackpoll breeds in forests of northern North America, from Alaska throughout most of Canada, to the mountains of New York and New England. They are a common migrant through much of North America. Come fall, they fly South to the Greater Antilles and the Northeastern coasts... less ↑

The northern waterthrush (Parkesia noveboracensis) is one of the larger New World warblers and one of the Nearctic-Neotropical migratory songbirds. It breeds in the northern part of North America in Canada and the northern United States including Alaska. This bird is migratory, wintering in Central America, the West Indies and Florida, as well as in Venezuela, Colombia, and Ecuador. It is a very rare vagrant to other South American countries and to western Europe. less ↑

The Venezuelan troupial (Icterus icterus) is the national bird of Venezuela and one of about 25 or so species of New World orioles. It is found in Colombia, Venezuela, and the Caribbean islands of Aruba, Curaçao, Bonaire, and Puerto Rico. Previously forming a superspecies simply named Turpial, it was recently split together with the orange-backed troupial and Campo troupial. less ↑

The yellow-hooded blackbird (Chrysomus icterocephalus) is a species of bird in the family Icteridae. It is found in grassy and brush areas near water in northern South America, and is generally fairly common. It is sexually dimorphic, and the genders resemble the respective genders of the larger yellow-headed blackbird of North America, though the male yellow-hooded blackbird lacks white in the wings. less ↑

The shiny cowbird (Molothrus bonariensis) is a passerine bird in the New World family Icteridae. It breeds in most of South America apart from the most dense jungles, mountains and deserts (although spreading into these habitats as they are modified by humans), the coldest southernmost regions (e.g. Tierra del Fuego), and on Trinidad and Tobago. It has relatively recently colonised Chile and many Caribbean islands, and has reached the United States, where it is probably breeding... less ↑

The scarlet tanager (Piranga olivacea) is a medium-sized American songbird. Until recently placed in the tanager family (Thraupidae), it and other members of its genus are now classified as belonging to the cardinal family (Cardinalidae). The species' plumage and vocalizations are similar to other members of the cardinal family, although the Piranga species lacks the thick conical bill (well suited to seed and insect eating) that many cardinals possess. less ↑

The scarlet flycatcher or austral vermilion flycatcher (Pyrocephalus rubinus) is a species of flycatcher, closely related to the vermilion flycatcher. It is found in southeastern Bolivia and Brazil, Paraguay to Argentina and Uruguay. It is recognized as a species by some taxonomic authorities, including the International Ornithologists' Union. Others still consider it to be a subspecies of the vermilion flycatcher. less ↑

The barn swallow (Hirundo rustica) is the most widespread species of swallow in the world. It is a distinctive passerine bird with blue upperparts, a long, deeply forked tail and curved, pointed wings. It is found in Europe, Asia, Africa and the Americas. In Anglophone Europe it is just called the swallow; in Northern Europe it is the only common species called a "swallow" rather than a "martin". less ↑

The black phoebe (Sayornis nigricans) is a passerine bird in the tyrant-flycatcher family. It breeds from southwest Oregon and California south through Central and South America. It occurs year-round throughout most of its range and migrates less than the other birds in its genus, though its northern populations are partially migratory. Six subspecies are commonly recognized, although two are occasionally combined as a separate species, the white-winged phoebe. less ↑

The sulphur-bellied flycatcher (Myiodynastes luteiventris) is a large tyrant flycatcher. This bird breeds from southeasternmost Arizona of the United States (the Madrean sky islands region of Arizona, southwestern New Mexico, and northern Sonora, Mexico) to Costa Rica. They are short distance migrants, spending winters in the eastern Andean foothills of Colombia, Ecuador, Peru, Bolivia, and Brazil, and are passage migrants over the southern portions of Central America. less ↑

The veery (Catharus fuscescens) is a small North American thrush species, a member of a group of closely related and similar species in the genus Catharus, also including the gray-cheeked thrush (C. minimus), Bicknell's thrush (C. bicknelli), Swainson's thrush (C. ustulatus), and Hermit thrush (C. guttatus). Alternate names for this species include Wilson's thrush (named so after Alexander Wilson) and tawny thrush. Up to six subspecie less ↑
