( Thomas , 1892)

The Brooke's squirrel ( Sundasciurus brookei ) is a species of squirrel from the genus of the Sunda tree squirrel ( Sundasciurus ). It is common in Borneo .

features

The Brooke croissant reaches a head-torso length of about 15.1 to 16.8 centimeters with a weight of about 115 to 132 grams. The tail becomes 12.0 to 13.6 centimeters long and is thus slightly shorter than the rest of the body. The animals are speckled brown on top. The ventral side consists of gray hair with white hair tips. There is an orange spot between the hind legs and the tail is striped.

distribution

The Brooke croissant occurs in northern and central Borneo in the Malay states of Sarawak and Sabah as well as in the Indonesian Kalimantan at medium altitudes of 600 to 1500 meters.

Way of life

Very little data is available on the Brooke's croissant lifestyle. It is diurnal and inhabits the high forests of the mountainous country of Borneo, where it lives mainly in the trees and is rarely found on the ground.

Systematics

The Brooke squirrel is classified as an independent species within the genus of the Sunda tree squirrel ( Sundasciurus ), which - depending on the author - consists of 15 to 17 species. The first scientific description comes from Oldfield Thomas from 1892, who described the species using individuals from Mount Dulit in Sarawak, Borneo.

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

Status, threat and protection

The Brooke croissant is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This is justified primarily with the presumed large and stable population of the species in the Kinabalu National Park . It is generally considered to be rare, but as a highland species it occurs mainly in areas that are little affected by strong habitat changes due to deforestation and changes in the use of forests on Borneo. There are no known threats to the survival of the population, only around Mt. Kinabalu there are impairments due to habitat changes.
