The Busuanga squirrel ( Sundasciurus hoogstraali ) is a species of squirrel from the genus of the Sunda tree squirrel ( Sundasciurus ). It lives on the island of Busuanga, part of the Philippines .
features
The Busuanga squirrel reaches a head-trunk length of about 20.0 to 20.5 centimeters, the tail is 16.0 to 17.5 centimeters long and thus slightly shorter than the rest of the body. The back color of the animals is dark brown with hair with a dark base and completely black hair. On the sides, the color changes into a slightly lighter clay to olive brown. The tail matches the color of the back at the base and then becomes lighter. The face is grayish, the hands and feet are dark brown. The underside is lighter and interspersed with long white hair.
distribution
The Busuanga squirrel is endemic to the island of Busuanga, which belongs to the Philippines and the Calamian Islands .
Way of life
No data are available on the way of life of the Busuanga squirrel. It originally lives in the primary forest of the lowlands, but can also exist well in secondary forest and even in gardens.
Systematics
The Busuanga 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 Colin Campbell Sanborn from 1952, who described the species on the basis of individuals from the island of Busuanga.
Apart from the nominate form, no further subspecies are distinguished within the species .
Status, threat and protection
The Busuanga croissant is classified as Least Concern by the International Union for Conservation of Nature and Natural Resources (IUCN). This classification is justified with the relatively frequent occurrence on the island and its ability to adapt to secondary habitats and also to gardens, where the species is, however, partially regarded as a pest. The genetic variability within the populations is great. Due to the foreseeable destruction of the habitat and the small size of the island, a classification as an endangered species is possible in the future.
