Movements, Home range and Social organization. At Krau Wildlife Reserve (Pahang, Malaysia), estimated population density of the Black-striped Squirrel is 5 ind / 100 ha. In Ulu Gombak Forest Reserve (Selangor, Malaysia), a single female had a home range estimated, in two different ways, to be 1 - 4 ha or 2 ha. In Ulu Gombak Forest Reserve, it reacts to terrestrial predators with a repeated staccato bark and tail flicking, which causes conspecific squirrels to run up a tree and be silent. The Black-striped Squirrel responds to an aerial predator with a soft “ chuckle ” if not immediately threatened, and with a “ rattle ” soundif it is a close encounter. Nearby squirrels react by freezing in position, and perhaps byjoining in the rattle call. In response to snakes, it give a squeak call, which causes other squirrels, sometimes ofthree different species, to join in mobbing the snake.
