The robin squirrel ( Dremomys gularis ) is a species of squirrel from the genus of the red-cheeked squirrel ( Dremomys ). It occurs in southern East Asia in the Chinese province of Yunnan and in northern Vietnam .

features

The robin squirrel reaches a head-trunk length of about 18.7 to 23 centimeters. The tail reaches a length of 14.5 to 18 centimeters and is thus significantly shorter than the rest of the body. The hind foot becomes 42 to 50 millimeters long, the ear length is 23 to 26 millimeters. The animals are monochrome gray-brown on top with olive and reddish shading. They are similar to the red-cheeked squirrel ( D. rufigenis ) and the Chinese red- cheeked squirrel ( Dremomys pyrrhomerus ), but have a conspicuous ock-reddish-brown color on the throat, chin and neck, which is clearly and sharply differentiated from the dark gray-blue belly color. The side stain typical of the genus is missing, indistinct or reduced to a line. The underside of the tail is red.

distribution

The robin squirrel is found in the Red River area in southern China in Yunnan Province and in northern Vietnam.

Way of life

Very little information is available about the robin squirrel's way of life. The species occurs at high altitudes in the range. She is sympathetic to the red squirrel, which, however, lives in the lower altitudes.

Systematics

The robin squirrel is classified as a separate species within the genus of the red-cheeked squirrel ( Dremomys ), which consists of six species. The first scientific description comes from Wilfred Hudson Osgood from 1932, who described the species using an individual from Fansipan near the city of Sa Pa in northwestern Vietnam near the Chinese border. The location was at an altitude of 2500 to 3000 meters. The animals were temporarily assigned to the Chinese red-cheeked squirrel ( Dremomys pyrrhomerus ) and the real red-cheeked squirrel ( D. rufigenis ), but are now considered a separate species.

Apart from the nominate form, no further subspecies are distinguished within the species .

Status, threat and protection

The European Union for Conservation of Nature and Natural Resources (IUCN) classifies the robin squirrel as not endangered (leat concern). This is justified by the large distribution area and the comparatively frequent occurrence as well as the ability to adapt to changes in habitat. Potential threats to the existence of this species are not known.
