The white-collared kite (Leptodon forbesi) is an Endangered species of bird in tribe Pernini and subfamily Perninae of family Accipitridae, the diurnal raptors. [1] [3] [4] It is endemic to northeastern Brazil. [3]
Until the early 2000s the white-collared kite was considered an aberrant plumage of the grey-headed kite (L. cayanensis) but morphological and other evidence strongly support its treatment as a full species. [5] It is monotypic. [3]
The species' specific epithet commemorates the British zoologist William Alexander Forbes.[ citation needed ]
The white-collared kite is about 50 cm (20 in) long and weighs 550 to 580 g (1.2 to 1.3 lb). Adults usually have a grey head with a white hindneck, but sometimes only the crown is gray and in other individuals the entire head is white. They have black upperparts, white underparts, and a black tail with a whitish tip and a broad ash-white band in the middle (or two white bands with a narrow black one between them). Their scapulars, secondaries, and inner primaries have broad white tips that are typically reduced or lost through wear. [6]
The white-collared kite is found only in parts of four states of northeastern Brazil: eastern Paraíba, eastern Pernambuco, eastern Alagoas, and southern Sergipe. It primarily inhabits the Atlantic forest though it has been spotted over mangroves. In elevation it occurs from near sea level to 600 m (2,000 ft). [6]
The white-collared kite is mostly sedentary but has been seen flying over sugar cane fields between isolated forest patches. [6]
Essentially nothing is known about the white-collared kite's hunting methods or diet. During the one documented observation the bird swooped from a perch, caught prey thought to be an insect, and returned to the same perch. [6]
The white-collared kite's breeding biology is almost unknown. Single birds and pairs have been observed making fluttering "butterfly" display flights between October and January, and an active nest was found in April. [6]
The white-collared kite makes a flight call "kua-kua-kua-kua" and "a cat-like 'eeeAAW'" during the display flight. [6]
The IUCN originally assessed the white-collared kite as Critically Endangered but since 2017 has rated it Endangered. It has a very small and fragmented range and its estimated population of between 250 and 1000 mature individuals is believed to be decreasing. Most of its original habitat has been cleared, primarily for agriculture, and small-scale logging continues in some of the remaining fragments. [1] It is known from only about 30 sites, some of which are private preserves. Brazilian authorities consider it Endangered. [6]
Kite is the common name for certain birds of prey in the family Accipitridae, particularly in subfamilies Milvinae, Elaninae, and Perninae. The term is derived from Old English cȳta, from the Proto-Indo-European root *gū- , "screech."
The Accipitriformes are an order of birds that includes most of the diurnal birds of prey, including hawks, eagles, vultures, and kites, but not falcons.
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 bat falcon is a bird of prey in the family Falconidae, the falcons and caracaras. It is found in Mexico, Central America, Trinidad, and every mainland South American country except Chile and Uruguay.
The plumbeous kite 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 laughing falcon is a medium-sized bird of prey in subfamily Herpetotherinae of family Falconidae, the falcons and caracaras. It is found from Mexico south through Central America and in every mainland South American country except Chile and Uruguay.
The pearl kite is a very small raptor found in open savanna habitat adjacent to deciduous woodland. It is the only member of the genus Gampsonyx. The scientific name commemorates the English naturalist William Swainson.
The gray-headed kite is a raptor found in open woodland and swamp forests. It shares the genus Leptodon with the extremely rare white-collared kite. It breeds from eastern Mexico and Trinidad south to Peru, Bolivia, Brazil and northern Argentina.
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 hook-billed kite, is a bird of prey in the family Accipitridae, which also includes many other diurnal raptors such as kites, eagles, and harriers. It occurs in the Americas, including the Rio Grande Valley of Texas in the United States, Mexico, the Caribbean, Central America, and tropical South America.
The collared puffbird is a species of bird in the family Bucconidae, the puffbirds, nunlets, and nunbirds. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela.
The Japanese sparrowhawk is a bird of prey in the family Accipitridae which also includes many other diurnal raptors such as eagles, buzzards and harriers. The bird is known by many alternative names such as the Japanese lesser, Asiatic, or Eastern sparrowhawk. This species is a small raptor with broader and rounder wings and a shorter tail. Its total length measures 23–30 centimetres (9.1–11.8 in). It has a dark back and whitish underside with brown-grey barring and red-brown colouring on the sides in males, and with heavier brown barring on the abdomen in females. Both sexes have a stripe across the throat, but its more obvious in the female. Is it typically identified by its appearance, but occasionally produces a chattering kiki-kik-kik... sound. This species generally breeds in parts of Russia, Korea, Japan, and China. There are three subspecies of Japanese sparrowhawk that differ by distribution and appearance. The species is globally listed as least concern, although it is listed as endangered in Japan and protected in China.
The double-toothed kite is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found from central Mexico through Central America into much of northern and eastern South America.
The rufous-thighed kite is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found regularly in Argentina, Bolivia, Brazil, Guyana, Paraguay, and Suriname and as a vagrant in Colombia, French Guiana, and Venezuela.
The white-browed hawk is a species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found Bolivia, Brazil, and Peru.
The white-necked hawk is a Vulnerable species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is endemic to Brazil.
The grey-backed hawk is an Endangered species of bird of prey in subfamily Accipitrinae, the "true" hawks, of family Accipitridae. It is found in Ecuador and far northern Peru.

The short-tailed hawk is an American bird of prey in the family Accipitridae, which also includes the eagles and Old World vultures. As a member of the genus Buteo, it is not a true hawk and thus also referred to as a "buteo" or "buzzard". The white-throated hawk is a close relative and was formerly included in the species B. brachyurus.
