Mindanao flying squirrel

Definition

The Mindanao flying squirrel (Petinomys crinitus) is a small gliding rodent endemic to the Philippines, where it is widespread and locally common in Mindanao’s forests. Like other flying squirrels it cannot truly fly, but glides on a furred membrane stretched between its limbs, steering with its tail as it moves between trees at night to feed on fruit, seeds, and other plant material.

Examples and Analogy

Where the Philippine flying lemur makes wide, plank-stiff glides like a hang glider, this pocket-sized squirrel is the paper-airline of the canopy: it launches from a trunk, spreads its patagium into a living airfoil, and lands deftly on a neighboring tree to continue feeding.

Usage Scenarios

Nocturnal mammal surveys in Mindanao protected areas document it through spotlighting and owl-prey remains; zoology courses use it to illustrate convergent gliding adaptations among Philippine mammals; and ecotour guides point out its dens in tree cavities.

Strategies

Because it is arboreal and nocturnal, successful observation means walking quiet forest trails at night with red-filtered lights near fruiting trees, rather than daytime searching where the squirrel hides in cavities.

Security and Safety Measures

It is a protected wildlife species under Republic Act No. 9147, so collection requires permits, and forest-edge communities are encouraged to retain large cavity trees during timber harvesting since the squirrel depends on mature stands.

Historical Context

The species was described from Mindanao specimens during the era when nineteenth-century collectors were mapping the island’s mammal fauna, and twentieth-century surveys found it across a range of elevations, distinguishing it from the larger Mindanao gliders it shares the canopy with.

Challenges and Controversies

Although assessed as a common species, its old-growth and mature-secondary forest habitat keeps shrinking, and biologists note that “common today” has quietly become “common where forest remains” for many Philippine small mammals.
