Whitehead's trogon (Harpactes whiteheadi) is a species of
It is primarily an insectivore, but also eats various plant materials, including fruits and seeds. Other than the timing of its breeding—typically between April and June—little is known about its breeding biology. The International Union for Conservation of Nature rates Whitehead's trogon as a near-threatened species. While its population numbers have not been quantified, the trogon is thought to be declining. Habitat loss is a key threat.
Taxonomy and etymology
English ornithologist Richard Bowdler Sharpe first
The genus name Harpactes is a transcription of the Greek word harpaktes, meaning "robber".[5] The species and common names honour the British explorer John Whitehead, who first collected the bird.[6]
Description
Like most trogons, Whitehead's trogon is
Voice
Whitehead's trogon vocalises only rarely. Its song is a loud series of four to five harsh, slow notes, evenly pitched and variously transcribed as "kwau kwau kwau kwau", "wark wark wark wark", or "poop poop poop poop".[3][7][9] It also has a rolling "burr" call, which is sometimes followed by a loud, descending "kekekeke".[3][9]
Distribution and habitat
Whitehead's trogon is
Behaviour
A shy and unobtrusive bird, Whitehead's trogon is easy to overlook as it sits quietly in the upper storey of dense forest. It is
Feeding
Like all trogons, Whitehead's trogon feeds primarily on insects, which it captures in
Breeding
Very little is known about the Whitehead trogon's breeding ecology.
Conservation
The International Union for Conservation of Nature has rated Whitehead's trogon as a near-threatened species. Although its population has not been quantified, it is thought to be decreasing. Habitat loss, both through logging and conversion to agricultural use, is occurring at lower elevations on some of mountains where it lives.[1]
