The Phayre squirrel ( Callosciurus phayrei ) is a species of squirrel from the genus of the real beautiful squirrel ( Callosciurus ). It occurs in South Asia from the southwest of Yunnan Province , People's Republic of China to Myanmar .

features

The Phayre croissant reaches a head-trunk length of 19 to 22 centimeters and a weight of about 280 grams. The tail reaches a length of about 16 to 21 centimeters and is therefore about as long as the rest of the body. The rear foot becomes 50 to 54 millimeters long. The back fur of the animals as well as the face, head and ears are agouti-colored . The peritoneum is bright to pale orange, but never red or gray. The back and stomach colors are separated by a black band about an inch wide that extends from the front legs to the rear legs. The feet are yellowish-sand colored or pale orange. The color of the tail corresponds to the back and has a light yellow stripe 12 to 15 millimeters wide and a black tip.

The skull has a total length of 46 to 54 millimeters.

distribution

The Phayre croissant occurs in South Asia from the southwest of the Yunnan Province , People's Republic of China to Myanmar . In China, its distribution is limited to Yunnan Province. The distribution area extends from the upper Irrawaddy and from Sittaung eastwards to the Saluen and southwards to its mouth in southern Myanmar.

Way of life

There is comparatively little data on the way of life of the Phayre croissants. It is like all other species of the genus primarily arboreal ( arboricol ) and feeds primarily on plants. As a habitat, it uses the tropical rainforest areas on the north bank of the lower reaches of the Saluen up to its mouth.

Systematics

The Phayre squirrel is classified as an independent species within the genus of the real beautiful squirrel ( Callosciurus ), which consists of 15 species. The first scientific description comes from Edward Blyth in 1856, who described an individual from the region around Mottama in what is now Myanmar . Some authors ascribed the species to the Pallas squirrel ( Callosciurus erythraeus ) as a subspecies.

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

Status, threat and protection

The Phayre squirrel is classified by the International Union for Conservation of Nature and Natural Resources (IUCN) as least concern due to its large and stable populations and the unknown threat to its existence. The populations are likely to be stable and no potential threats are known for this species.
