Trogon šedoprsý (Harpactes whiteheadi) je rod druh ptáka z čeledi trogonovitých. Jedná se o druh endemický pro ostrov Borneo v jihovýchodní Asii. Druhové jméno dostal na počest Johna Whiteheada, který ho objevil na své cestě k hoře Kinabalu roku 1888. Trogoni šedoprsí žijí obvykle v nadmořské výšce 900 až 1500 metrů nad mořem.

Whitehead's trogon (Harpactes whiteheadi) is a species of bird in the family Trogonidae. It is endemic to the island of Borneo, where it is an uncommon resident in primary mountain forest. One of Borneo's largest trogons at 29 to 33 cm (11 to 13 in) long, it is sexually dimorphic. The male is crimson on the head, nape, and underparts, with a black throat and grey chest; the rest of his upperparts are cinnamon-coloured. The female is similarly patterned, but cinnamon-brown where the male is scarlet. The species was first described for science by Richard Bowdler Sharpe in 1888, who named it for British explorer and collector John Whitehead. There are no subspecies.
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.
English ornithologist Richard Bowdler Sharpe first described Whitehead's trogon for science in 1888, using a specimen collected on Mount Kinabalu, in the Malaysian state of Sabah.[2] He gave it the scientific name Harpactes whiteheadi, assigning it to the genus containing other Asian trogons.[2] There are no subspecies.[3] Molecular studies indicate that it is most closely related to the Philippine trogon.[4]
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]
Like most trogons, Whitehead's trogon is sexually dimorphic; the male is considerably more colourful than the female.[7] It ranks among Borneo's largest trogons, measuring 29 to 33 cm (11 to 13 in) in length.[nb 1][3][9] The male is crimson on the forehead, crown, nape, and sides of the head, with bare blue skin around the eyes. The rest of his upperparts are cinnamon-brown. His throat is black, shading into a grey breast, but the rest of his underparts are crimson.[9] His wings are primarily black, with fine white barring on the secondaries and coverts.[2] His tail is mostly white underneath; above, the two central tail feathers are cinnamon with a broad black tip, and the remaining tail feathers are primarily black. The outermost tail feathers are white on the terminal half and along the outer web.[2] He has a blue beak, pinkish-brown legs and feet, and reddish-brown irises.[9][2] The female is similarly patterned, but duller, with cinnamon-brown replacing the crimson of the male.[3] The barring on her secondaries and wing coverts is cinnamon-brown rather than white.[10] The immature female is similar to the adult female, but her entire ventral side is uniformly coloured, lacking the adult's black throat and grey upper breast. She also has less blue colouring on her beak.[11]
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]
Whitehead's trogon is endemic to the island of Borneo, where it occurs in mountainous areas between 900 and 2,000 metres (3,000 and 6,600 ft) in elevation.[3] Restricted to primary forest, it favours damp valleys.[7] It is an uncommon and poorly-known resident species.[12]
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 resident where it occurs. It associates loosely with mixed species flocks containing chestnut-hooded and Sunda laughingthrushes, Whitehead's broadbills and Sunda cuckooshrikes.[11]
Like all trogons, Whitehead's trogon feeds primarily on insects, which it captures in sallying flight from a perch, or gleans from foliage.[7] Most of this prey is fairly large, including grasshoppers, locusts, stick insects, and leaf insects; however, insects as small as ants are taken.[9] It also eats fruit, seeds and other plant material.[7][13] Though it generally perches just under the canopy, it typically hunts in the understorey.[3][7] In the mixed flocks it accompanies, it usually hunts at lower levels than the other species do.[11] Individuals have been found with stones in their stomachs.[9]
Very little is known about the Whitehead trogon's breeding ecology.[9] Birds have been found in breeding condition in late March and October; the latter date suggests the possibility of multiple broods or geographical variation in the breeding period. Nesting is known to occur in April, young birds have been collected in June, and family groups have been seen together in July.[14] However, the nest and eggs remain undescribed, and details of its breeding biology—incubation and nesting periods, size of clutch, length of time to fledging, division of nestling care, and so forth—are not known.[9]
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]

El trogón de Borneo (Harpactes whiteheadi)[2] es una especie de ave trogoniforme de la familia Trogonidae endémica de Borneo.[3] Su nombre científico se debe al explorador británico John Whitehead (1860-1899).[4]
Mide entre 29 y 31 cm de longitud, incluida su larga cola. Presenta dimorfismo sexual en su coloración. Los machos tienen el plumaje de la cabeza rojo, salvo la garganta que es negra. Su pecho es blanco y el resto de las partes inferiores son rojas. Su espalda es de color canela y sus alas son negras con bordes blancos en las plumas de vuelo. Las plumas centrales de su cola son de color castaño, las de los laterales son blancas y las intermedias negras. Presenta anillos oculares negros. Su pico es robusto y ligeramente curvado hacia abajo y de color negruzco azulado. Las hembras son de tonos ocres en las zonas rojas de los machos y la espalda.
Se encuentra únicamente en el norte de la isla de Borneo,[5] Su hábitat natural son las selvas húmedas de montaña. Está amenazado por la pérdida de hábitat.

De Whiteheads trogon (Harpactes whiteheadi) is een endemische vogelsoort uit de familie Trogons (Trogonidae). Deze vogel werd ontdekt door John Whitehead in de regenbossen rond de berg Kinabalu in Sabah (Maleisië).
Zoals alle trogons is dit een mooi gekleurde vogel. De geslachten verschillen sterk van elkaar. Het mannetje van de Whiteheads trogon heeft scharlakenrode kop en nek. De rug en stuit zijn oranje tot oker. De staart is ook okerkleurig met zwart in de buitenste staartpennen en aan het uiteinde. De achterkant van de staart is zwart met wit. De vleugels zijn tot de helft okerbruin en daarna zwart met dunne witte strepen. De keel is zwart, geleidelijk overgaand in grijs. Dit grijs is het typische kenmerk van de Whiteheads trogon ten opzichte van andere trogons in het oriëntaalse gebied. Er is een duidelijk scheiding tussen de borst en de buik, waarbij de buik scharlakenrood van kleur is. Het vrouwtje heeft een donkerolijfkleurige kop, een donkerder rug, lichte roodbruine strepen op de vleugels. Daarnaast is de onderzijde kaneelkleurig en is de buik valer van kleur.
De snavel van een volwassen exemplaar is blauwachtige, de iris is donkerrood of bruin. De poten van de Whiteheads trogon zijn lichtgrijs.
Deze soort is inclusief staart 33 centimeter lang.
De Whiteheads trogon leeft in onontgonnen bossen op een hoogte tussen de 900 en 1500 meter boven zeeniveau in bergachtige gebieden op de grens van Sabah, Sarawak en het noordoosten van Kalimantan.
De vogel heeft een voorkeur voor dichte ondergroei in vochtige valleien in bergland. Net als andere soorten trogons zitten deze vogels rechtop en kunnen ze vaak lange periodes in dezelfde houding blijven zitten.
Door ontbossingen als gevolg van houtkap en omzetting van bos in landbouwgebied krimpt het leefgebied en daarom staat de vogel als gevoelig op de rode lijst.[1]
