Southern Palawan tree squirrel

The Southern Palawan tree squirrel (Sundasciurus steerii), known locally as bising, is a species of rodent in the family Sciuridae that is endemic to the Philippines. Its natural habitat is subtropical or tropical dry forest. It belongs to Sundasciurus, a genus of small tree squirrels of Southeast Asia. In 1967 researchers studying parasites of squirrels from Palawan and Taiwan found two nematode worms in this species, which they named Brevistriata sundasciuri and Calypsostrongylus ogdeni, so the animal is part of the type record of both parasites. Beyond its range, habitat and parasites, the English Wikipedia article gives no further description of its size, diet or behaviour.
