The cattle tyrant (Machetornis rixosa) is a species of bird in the tyrant-flycatcher family Tyrannidae. In Brazil, it is called suiriri-cavaleiro. [3] 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 may not be distinct from M. r. flavigularis. The genus name was given to the species by George Robert Gray and is derived from the Ancient Greek makhētēs for fighter and ornis for bird, a reference to its pugnacious behaviour and habit of dispossessing other species of their nests. The specific name comes from the Latin rixosus meaning quarrelsome, again referring to the behaviour and temperament of the species. [4]
The species has a disjunct distribution, with the nominate race breeding from northern Argentina and Bolivia to the north-eastern tip of Brazil, and the two other subspecies ranging from Panama to Venezuela and eastern Ecuador. The species inhabits drier open and semi-open habitats, and avoided forested and wooded areas. It can be found in savannah, pastureland, parkland, agricultural land and even gardens. [4] Due to deforestation, the species has recently colonized areas where it was previously absent, such as northeast Ecuador.
The cattle tyrant is a highly terrestrial tyrant-flycatcher, 20 cm (7.9 in) long and weighing 29–40 g (1.0–1.4 oz). The plumage of the nominate subspecies is mostly olive-brown above and yellow below. The head is grey with a thin eyestripe and a white throat. The thin bill and legs are black. The two other subspecies vary from the nominate in having a yellow throat. [4]
Cattle tyrants feed on insects, mostly from the ground. It may follow cattle or other large animals for some distance, catching flushed prey, or even hitch rides on these animals, and then snatching flushed prey with a quick sally-flight. It may sometimes hawk for insects from a high perch. [4] The species is sometimes reported to have a cleaning symbiosis with the large mammals it lives with. It takes ticks off mammals only occasionally, but it will sometimes hunt horseflies attempting to land on capybaras. [3]
Cattle tyrants build bulky nests or steal the nests of rufous-fronted thornbirds. 3 to 4 eggs are laid and incubated for 14 days. The chicks fledge after 15 days. [4]
Fantails are small insectivorous songbirds of the genus Rhipidura in the family Rhipiduridae, native to Australasia, Southeast Asia and the Indian subcontinent. Most of the species are about 15 to 18 cm long, specialist aerial feeders, and named as "fantails", but the Australian willie wagtail is a little larger, and, though still an expert hunter of insects on the wing, concentrates equally on terrestrial prey.
The great crested flycatcher is a large insect-eating bird of the tyrant flycatcher family. It is the most widespread member of the genus Myiarchus in North America, and is found over most of the eastern and mid-western portions of the continent. It dwells mostly in the treetops and rarely is found on the ground.
The yellow-bellied elaenia is a small bird of the tyrant flycatcher family. It breeds from southern Mexico and the Yucatán Peninsula through Central and South America as far as northern Argentina, and on Trinidad and Tobago.
The great kiskadee, called bem-te-vi in Brazil, pitogue in Paraguay, and benteveo or bichofeo in Argentina, is a passerine bird in the tyrant flycatcher family Tyrannidae. It is the only member of the genus Pitangus.
The piratic flycatcher is a passerine bird, the only member of the genus Legatus. It is a resident breeder from southern Mexico and Trinidad south to Bolivia and Argentina. At least some birds from Central America and Trinidad are migratory, and this species also visits Tobago.
The streaked flycatcher is a passerine bird in the tyrant flycatcher family.
The southern tropical pewee is a small passerine bird in the tyrant flycatcher family. It breeds from southern Brazil and Paraguay south to Argentina.
The southern beardless tyrannulet is a small passerine bird in the tyrant flycatcher family. It breeds from Costa Rica through South America south to Paraguay, Bolivia, and Argentina.
The lilac-breasted roller is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula. It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground. Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height, descending in swoops and dives, while uttering harsh, discordant cries. The sexes do not differ in coloration, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya. Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller and Mosilikatze's roller.
The vermilion flycatcher is a small passerine bird in the tyrant flycatcher family found throughout South America and southern North America. It is a striking exception among the generally drab Tyrannidae due to its vermilion-red coloration. The males have bright red crowns, chests, and underparts, with brownish wings and tails. Females lack the vivid red coloration and can be hard to identify—they may be confused for the Say's phoebe. The vermilion flycatcher's song is a pit pit pit pidddrrrreeedrr, which is variable and important in establishing a territory. Riparian habitats and semi-open environments are preferred. As aerial insectivores, they catch their prey while flying. Their several months-long molt begins in summer.
The social flycatcher is a passerine bird from the Americas, a member of the large tyrant flycatcher family (Tyrannidae).
The ash-throated flycatcher is a passerine bird in the tyrant flycatcher family.
The tufted tit-tyrant is a species of bird in the tyrant flycatcher family Tyrannidae. This species is found in western South America; its range stretches from southern Colombia south along the Andes mountains to Tierra del Fuego. It prefers to live in upper montane forests and shrublands; however, it is a habitat generalist and can be found across a wide range of ecosystems. The tufted tit-tyrant has three subspecies, including the nominate subspecies Anairetes parulus parulus, A. p. aequatorialis, and A. p. patagonicus, and is very closely related to the Juan Fernández tit-tyrant. It is very small with a distinctive and conspicuous crest. The bird's head is black overall with white supraloral and postocular stripes. Its dull grayish-brown back contrasts with its white throat and breast that are covered with black streaks and pale, unmarked yellow underbelly. There are few noticeable differences in plumage between the subspecies. It is a vocal flycatcher with a broad repertoire of songs.
The smoke-colored pewee is a species of bird in the family Tyrannidae. The species is characterized by a uniform dusky-grey plumage.
The cliff flycatcher is a species of bird in the tyrant flycatcher family, Tyrannidae. The cliff flycatcher is the only species in the genus Hirundinea after the swallow flycatcher was merged, becoming subspecies Hirundinea ferruginea bellicosa. It is native to South America, where its natural habitats are cliffs and crags in the vicinity of subtropical or tropical dry forest, subtropical or tropical moist lowland forest, subtropical or tropical moist montane forest, and heavily degraded former forest.
The ashy flycatcher is a species of bird in the Old World flycatcher family Muscicapidae. It is found throughout sub-Saharan Africa, excluding the drier areas of South Africa, Botswana, and Namibia, where it inhabits subtropical or tropical dry forest, subtropical or tropical moist lowland forest, and savanna. It has a disputed generic placement, with different authorities variously putting it in Muscicapa, Fraseria, or other genera. Ashy flycatchers are mostly grey in colour, with pale grey or white underparts, and display no sexual dimorphism.
The drab water tyrant is a species of bird in the family Tyrannidae, the tyrant flycatchers, and is the only species in the monotypic genus Ochthornis. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, and Venezuela, where its natural habitat is rivers.
The Mascarene paradise flycatcher is a species of bird in the monarch-flycatcher family Monarchidae. It is endemic to the Mascarene islands of Mauritius and Réunion. There are two subspecies recognized: the nominate subspecies from Réunion, also known as the Réunion paradise flycatcher; and T. b. desolata from Mauritius. The Mascarene paradise flycatcher was originally described in the genus Muscicapa and the subspecies T. b. desolata was originally described as a separate species.
The white-naped xenopsaris, also known as the reed becard and white-naped becard, is a species of suboscine bird in the family Tityridae, the only member of the genus Xenopsaris. It is found in South America, in humid subtropical and tropical savanna climates in most of the countries east of the Andes: Venezuela, Brazil, Bolivia, Paraguay, Uruguay, and Argentina. Living in open woodland and other open forest habitats, it is mostly sedentary, though some populations may be migratory. The species, which is closely related to becards and tityras, was thought to be either a tyrant-flycatcher or cotinga, before it was placed in Tityridae.
The yellow-billed jacamar is a species of bird in the family Galbulidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.
