The Sumatran pheasant ( Lophura hoogerwerfi ) is a Hühnervogel art from the family of pheasant-like , in the mountain forests in the northwest of Sumatra is endemic . Many authors regard it as a subspecies of the Salvadoran pheasant ( Lophura inornata ), which is also native to Sumatra . The rooster has not yet been officially described, a description given is based on an inadequate sighting. The type specimen was one of two hens collected in the late 1930s.

The specific epithet honors the Dutch ornithologist Andries Hoogerwerf .

description

The Sumatra pheasant reaches a body length of 46 to 55 cm. The cock of this hoodless, short-tailed species is predominantly bluish black in color, the featherless eye region is red. There are inconspicuous blue hems on the feathers on the top. The legs and feet are light gray.

In contrast to the maroon hen of the Salvadoran pheasant, the hen is predominantly dark reddish-brown. The plumage is finely wavy black, the throat whitish and the underside washed out yellowish brown. In contrast to the Salvadori hen, the light shafts and the isabel-black-speckled central stripes are also missing here. The tail is black, the iris is amber, and the legs are dark gray.

Distribution and existence

The Sumatra pheasant is endemic to northwest Sumatra. The species is poorly described and sightings have been few. The observation of a rooster comes from the Gunung Leuser National Park in the highlands of Gayo . In 1979, several family groups were seen there, and in 1998 a hen was seen north of Mount Leuser on the Jagong River in the Beutong region . In 1998/1999 five individuals of both sexes were discovered in a market in Medan , who came from the Gunung Leuser National Park. Three couples of wild origin are currently living in captivity on Java.

It is believed that the population is below 10,000 individuals and is threatened by habitat deforestation. The species is therefore classified as endangered (“vulnerable”).

habitat

The type specimen was discovered in spring 1939 by George Vanderbilt (1914–1961) in a primary forest with little undergrowth at Lake Telaga Meluwak between 1200 and 1400 m. Presumably it was a tropical rainforest of the submontane level. The terrain has been described as hilly. A second specimen was shot at a height of 600 m. The birds observed in the Gunung Leuser National Park moved on the sparsely vegetated forest floor on relatively dry slopes at an altitude between 1200 and 2000 m.
