The Mindanao flying squirrel ( Petinomys crinitus ) is a flying squirrel from the genus of the dwarf flying squirrel ( Petinomys ). It occurs on the Indonesian island group Mindanao .
features
The Mindanao flying squirrel reaches a head-torso length of about 31 centimeters and a tail length of about 26 centimeters. The weight is around 1200 grams. It is thus somewhat smaller than the similar Palawan flying squirrel ( Hylopetes nigripes ) and the sympatric living Petinomys mindanensis . The back and head color is gray to brown, the ventral side is lighter. The ears are small with three small tufts of hair. The feet are gray-brown, the tail brown and, in contrast to Petinomys mindanensis, flattened.
Like all dwarf gliding squirrels, it has a hairy skin that connects the wrists and ankles and is enlarged by a fold of skin between the hind legs and the base of the tail. The sliding skin is muscular and reinforced at the edge, it can be tensed and relaxed accordingly in order to control the direction of the gliding flight.
distribution
The Mindanao flying squirrel occurs on the Indonesian island group Mindanao and there on the islands of Mindanao, Basilan , Dinagat and Siargaovor .
Way of life
The Mindanao flying squirrel occurs in wooded areas at altitudes of 500 to 1600 meters, and is known from various habitats in the lowlands to the mountainous regions. It prefers primary forests and especially oak forests of high altitude.
Little data or observations are available about the way of life of the Mindanao flying squirrel. In its way of life it probably corresponds to other flying squirrels; it is therefore probably tree-living or partly living on the ground, largely nocturnal and feeds on plants.
Systematics
The Mindanao flying squirrel is classified as an independent species within the genus of the dwarf flying squirrel ( Petinomys ), which contains a total of nine species. The first scientific description comes from Ned Hollister from 1911 on the basis of an individual from the island of Basilan in the Sulu archipelago in the Mindanao archipelago . No subspecies are distinguished within the species.
Existence, endangerment and protection
The Mindanao flying squirrel is listed by the International Union for Conservation of Nature and Natural Resources (IUCN) as non-threatened ("least concern") due to its assumed frequent occurrence and stable populations in the low-endangered oak forests at high altitude. There are no data on the stocks, but no potential sources of danger are assumed, as the primary forests at high altitudes are little affected by logging and conversion to agricultural land.
