features

The Alaschan redstart reaches a body length of 14 to 16 cm and is colored orange, black and gray. In the male, the upper head, neck and sides of the neck are pale to medium gray. The coat, back, rump and tail are bright reddish brown orange, the shoulder feathers and wings black with white wing bands. The underside is reddish brown orange, slightly whiter on the belly. The females are more inconspicuous, dull earth-brown in color. Their wings are blackish brown, the tips of the wing covers, arm wings and umbrella feathers light. The rump and outer tail feathers are orange, the central tail feathers blackish brown. The beak, feet and iris are black.

distribution

The Alashan Redstart lives and breeds in the northern and central People's Republic of China ( Qinghai , Gansu and Ningxia ). Outside the breeding season, from October to March, its distribution area extends east to Hebei and Beijing . In northeast China he is a rather rare winter visitor . Due to the limited ornithological coverage of large parts of its range, little is known about its breeding areas and habitat requirements.

Habitat and way of life

The Alaschan Redstart breeds on bush-covered, rocky slopes, in river plains with bushes and in the upper, coniferous mountain forests at heights of 3,300 meters to the tree line . In winter it retreats to an altitude of 2,000 meters. In autumn it apparently feeds mainly on berries.

Etymology and history of research

Prschewalski discovered the alashan redstart on his first expedition from 1870–1873 and described it under the name Rutirilla [sic] alaschanica . The Ala Shan was found in China. In 1817 Forster established the genus Phoenicurus , into which the Alashan redstart was later classified. "Phoenicurus" is composed of the Greek words "phoinix, phoinikos φοινιξ, φοινικος " for "carmine, red" and "-ouros -ουρος " for " -tailed ". The specific epithet »alaschanicus« refers to the place where the type specimen was found.

Hazard and protection

Little is known about population size and threats to the species. Forest loss could reduce the assumed moderately small population of 6,000 to 15,000 sexually mature individuals. There have been reports of sightings from the Helanshan Mountain Nature Reserve and Yanchiwan Nature Reserve . The IUCN (International Union for Conservation of Nature and Natural Resources) classifies the Alaschan Redstart as Near Threatened (NT).
