The plumbeous kite (Ictinia plumbea) is a bird of prey in the family Accipitridae that is resident in much of northern South America. It is migratory in the northern part of its range which extends north to Mexico. It feeds on insects which it catches either from a perch or while in flight.
The plumbeous kite was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae . He placed it with the eagles, hawks and relatives in the genus Falco and coined the binomial name Falco plumbeus. [2] Gmelin based his description on the "spotted-tailed hawk" that had been described in 1781 by the English ornithologist John Latham from a specimen from Cayenne in a private collection in London. [3] It is now placed with the Mississippi kite in the genus Ictinia that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot. [4] [5] The genus name is from the Ancient Greek iktinos for a kite. The specific epithet plumbea is from Latin plumbeus meaning "leaded", "plumbeous" or "lead-coloured". [6] The species is monotypic: no subspecies are recognised. [5]
The plumbeous kite is 34–37.5 cm (13.4–14.8 in) in overall length. The male weighs 190–267 g (6.7–9.4 oz), the slightly larger female 232–280 g (8.2–9.9 oz). It has long, pointed wings. Adults are mainly slate-grey, with a paler head and underparts. The short black tail has 2-3 white bands on the undersurface. The eyes are red and the legs are orange. In flight, this kite shows a rufous primary patch. Sexes are similar, but immature birds have white-streaked grey upperparts and dark-streaked whitish underparts. They lack the rufous wing patch. The call of plumbeous kite is a whistled si-see-oo. [7]
The plumbeous kite is darker gray overall than the strongly migratory Mississippi kite which has white patches on the secondaries and lacks the rufous patches on the primaries. [8]
The plumbeous kite is a bird of lowland forest and savannah. It breeds in the Neotropical realm, from eastern Mexico to Peru, Bolivia and Argentina. It also breeds on Trinidad. Birds in the north and south of the breeding range, including the populations in Central America, Trinidad, Venezuela and Colombia, and southern Argentina and Brazil, are migratory, moving into tropical South America in the northern winter. [7]
It is not particularly gregarious, although it is sometimes seen in flocks during migration. [8]
The deep stick nest is placed high in a tree, sometimes in a mangrove swamp over water. [7] The clutch is usually a single egg but occasionally two eggs are laid. They are either white of very pale blue and measure about 41 mm × 35 mm (1.6 in × 1.4 in). The eggs are incubated for 32-33 days by both parents. [8] The chicks are covered with white down and are fed by both parents. The young fledge when around a month of age. [7]
The plumbeous kite catches insects either in flight or from a perch. It will also occasionally prey on snails, frogs, lizards, bats, birds and snakes. [8] [9] [10]
The short-toed snake eagle, also known as the short-toed eagle, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, buzzards and harriers. The genus name Circaetus is from the Ancient Greek kirkos, a type of hawk, and aetos, "eagle". The specific gallicus means "of Gallia".
The black-shouldered kite, also known as the Australian black-shouldered kite, is a small raptor found in open habitats throughout Australia. It resembles similar species found in Africa, Eurasia and North America, including the black-winged kite, a species that has in the past also been called "black-shouldered kite". Measuring around 35 cm (14 in) in length, with a wingspan of 80–100 cm (31–39 in), the adult black-shouldered kite has predominantly grey-white plumage and prominent black markings above its red eyes. It gains its name from the black patches on its wings. The primary call is a clear whistle, uttered in flight and while hovering. It can be confused with the related letter-winged kite in Australia, which is distinguished by the striking black markings under its wings.
The gull-billed tern, formerly Sterna nilotica, is a tern in the family Laridae. It is widely distributed and breeds in scattered localities in Europe, Asia, northwest Africa, and the Americas. The Australian gull-billed tern was previously considered a subspecies.
The black wheatear is a wheatear, a small passerine bird in the Old World flycatcher family Muscicapidae. It is found in southern Spain and western North Africa.
The swallow-tailed kite is a pernine raptor which breeds from the southeastern United States to eastern Peru and northern Argentina. It is the only species in the genus Elanoides. Most North and Central American breeders winter in South America where the species is resident year round.
The gray kingbird or grey kingbird, also known as pitirre, petchary or white-breasted kingbird, is a passerine bird in the tyrant flycatchers family Tyrannidae. The species was first described on the island of Hispaniola, then called Santo Domingo, thus the dominicensis name.
The Mississippi kite is a small bird of prey in the family Accipitridae. Mississippi kites have narrow, pointed wings and are graceful in flight, often appearing to float in the air. It is common to see several circling in the same area.
The nankeen night heron is a heron that belongs to the genus Nycticorax and the family Ardeidae. Due to its distinctive reddish-brown colour, it is also commonly referred to as the rufous night heron. It is primarily nocturnal and is observed in a broad range of habitats, including forests, meadows, shores, reefs, marshes, grasslands, and swamps. The species is 55 to 65 cm in length, with rich cinnamon upperparts and white underparts. The nankeen night heron has a stable population size, and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
The tropical gnatcatcher is a small active insectivorous songbird, which is a resident species throughout a large part of northern South America. It was formerly considered as conspecific with the white-browed gnatcatcher.
The grey-faced buzzard is an Asian bird of prey. It is typically 41–46 cm (16–18 in) in length, making it a small-sized raptor. It breeds in Manchuria, Korea and Japan; it winters in South-east Asia.
The grey goshawk is a strongly built, medium-sized bird of prey in the family Accipitridae that is found in eastern and northern Australia. The white morph of this species is known as the white goshawk.
The southern boubou is a bushshrike. Though these passerine birds and their relations were once included with true shrikes in the Laniidae, they are not closely related to that family.
The capped wheatear is a small insectivorous passerine bird that is widely distributed over southern Africa. It was formerly classed as a member of the thrush family Turdidae, but is now placed in the Old World flycatcher family, Muscicapidae.
The red-capped lark is a small passerine bird that breeds in the highlands of eastern Africa southwards from Ethiopia and Somaliland. In the south, its range stretches across the continent to Angola and south to the Cape in South Africa.
The marbled wood quail, also known as the Amazonian wood quail, is a species of bird in the New World quail family. It has an extensive distribution in Central America and the northern part of South America. Its natural habitat is subtropical or tropical moist lowland forests.
The rufous crab hawk or rufous crab-hawk, is a Near Threatened species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found on Trinidad and along the South American coastline from eastern Venezuela to southern Brazil.
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 pale thrush is a passerine bird of the eastern Palearctic belonging to the genus Turdus in the thrush family Turdidae. It is closely related to the eye-browed thrush and grey-backed thrush.
Ictinia is a genus of birds in the family Accipitridae. It contains two species that are native to the Americas.
The northern potoo is a nocturnal bird belonging to the potoo family, Nyctibiidae. It is found from Mexico south to Costa Rica, and on the islands of Jamaica and Hispaniola. It was formerly classified as a subspecies of the common potoo but is now usually treated as a separate species based on differences in vocalizations.
