A large kite, it is blackish above and white below, with a white leading edge to the wing and white underwing- coverts. There may also be white spotting on the mantle and white tips to the secondaries 2 3 5 7 8although these last two features have been difficult to confirm in wild specimens 9. The head is white to greyish with, as the name suggests, a white collar around the neck 2 3 7 8and the tail may have one or two dark bands 9.
The wings of the white-collared kite are quite broad and blunt, the tail is relatively long and rounded, and the head is small, with a slender beak 7. The white-collared kite was previously considered a possible variant of the closely-related grey-headed kite, Leptodon cayanensis 2 5 7 However, it can be distinguished from the adult grey-headed kite by the white collar, white rather than black leading edge to the wings, white underwing- covertswhiter forehead, and different tail pattern 2 3 5 7 8.
Light- morph juvenile grey-headed kites are browner above than the white-collared kite, have a black crown, and have black-tipped feathers on the upperparts 3.
Very little is known about the biology and life history of the white-collared kite 2 3 5 8. However, it is vorbesi to forbeso similar to the grey-headed kite 5 8which feeds on a variety of insects as well as leptoron, young birds, frogs, lizards, snakes and molluscs 7.
The grey-headed kite builds a thin platform nest of sticks and twigs, high in the forest canopy, and lays a clutch of two to three eggs 7. The calls of this species include a rapid series of short, high kua-kua-kua-kua notes, as well as a nasal call which somewhat resembles that of a peacock 3 The white-collared kite is known from just a handful of sites in the states of Pernambuco and Alagoas in north-eastern Brazil 2 3 5 7 10and has also recently been recorded further south, in the state of Sergipe 9.
This species inhabits Atlantic coastal forestat elevations up to about metres 2 3 5 7 8 With a total population so far estimated at perhaps fewer than mature individuals, and a highly restricted and fragmented range 3 10forbesii white-collared kite may be the most endangered bird of prey in South America 6and indeed is one of the rarest birds in the world 5.
The Atlantic coastal forest of Brazil is highly threatened by habitat loss, mainly in the form of clearance for sugarcane and coffee plantations, and pressure from urbanisation 7 8 In addition, a lack of knowledge about the white-collared kite, whose very existence as a distinct species was still debated as recently ashinders efforts to conserve it 5 6 8.
Further surveys and research into the white-collared kite are urgent priorities 3 6 10and studies have been recommended to clarify its taxonomic status using genetic analysis 3. The designation of Murici as a biological reserve and the protection of other forest areas 3 10 13such as Mata do Coimbra, Ibateguara, Alagoas 12will also be important to its continued survival.

Find out more To find out more about the white-collared kite and its conservation see: Global Raptor Information Network: Biodiversity Hotspots – Atlantic Forest: Glossary Atlantic Forest A highly biodiverse region found along elptodon east coast of South America, comprising several different vegetation types, including high-altitude grassland, and lowland and montane forest.
The coastal Atlantic forest is a narrow strip of about 50 to kilometres along the coast, which covers about 20 percent of the Atlantic Forest region. Coverts Small feathers concealing the bases of larger flight feathers, usually on the wings or tail.
Mantle In birds, the wings, shoulder feathers and back, when coloured differently from the rest of the body. Molluscs A diverse group of invertebrates, mainly marine, that have one or all of the following; a horny, toothed ribbon in the mouth the radulaa shell covering the upper surface of the body, and a mantle or mantle cavity with a type of gill. Includes snails, slugs, shellfish, octopuses and squid.

Morph One of two or more distinct types of a given species, often distinct colour forms, which occur in the same population at the same time that is, are not geographical or seasonal variations. Secondaries In birds, the shorter flight feathers projecting along the inner edge of the wing. Taxonomic Relating to taxonomy, the science of classifying organisms, grouping together animals which share common features and are thought to have a common ancestor.
