The Kinabalu squirrel ( Callosciurus baluensis ) is a species of squirrel from the genus of the real beautiful squirrel ( Callosciurus ). It occurs in the north of the island of Borneo .

features

The Kinabalu croissant reaches a head-torso length of 23 to 25 centimeters and a weight of about 370 grams. The tail reaches a length of about 24 to 25 centimeters and is therefore about as long as the rest of the body. The back fur of the animals is colored black-gray. The underside is matte dark red with a dark black line in the middle. The stomach and back are separated from each other by short, light side lines. There are reddish tints in the otherwise gray fur on the face and legs.

distribution

The Kinabalu croissant occurs in the north of the island of Borneo in the Malay states of Sabah and Sarawak and the border area of the Indonesian part of Kalimantan .

Way of life

Very little data and observations are available on the way of life of the Kinabalu squirrel. It mainly uses the oak and cloud forests of the highlands between 300 and 1800 meters as a habitat. The species, like all other species in the genus, is primarily arboreal ( arboricol ), but it is rarely found on the ground. It probably also feeds primarily on plants, and more rarely on insects.

Systematics

The Kinabalu 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 J. Lewis Bonhote from 1901, who described the species from Mount Kinabalu in the Malay province of Sabah.

Apart from the nominate form, no further subspecies are distinguished within the species . According to other authors, C. baulensis baramensis in Sabah is separated from the nominate form as a subspecies with a slightly speckled fur.

Status, threat and protection

The Kinabalu squirrel is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN) due to its comparatively large distribution area, its occurrence in protected areas and due to the likely relatively stable populations. No specific risks for the stocks are known.
