The colugo sleeps in hollow trees or clings onto branches in dense foliage during daytime.[1] When they engage in this hanging behavior from branches, they keep their heads upright, unlike bats.[2] On the ground, colugos are slow and clumsy, and not able to stand erect, so they rarely leave the canopy level of the forest, where they glide from tree to tree to get to food or their nests, which are also high in the trees. In the trees, though, colugos are quite effective climbers, though they are slow; they move in a series of lingering hops as they use their claws to move up the tree trunk.[3] Foraging only at night, colugos on average forage for 9.4 minutes about 12 times per night.[4] They typically leave their nests at dusk to begin their foraging activity.[10] When foraging, returning to the nest, or just moving around, the Philippine flying lemur uses its patagium to glide from tree to tree. The patagium is also used for cloaking the colugo when it is clinging to a tree trunk or branch, and sometimes it is even seen curled up in a ball, using its patagium again as a cloaking mechanism among palm fronds often in coconut plantations.[6]
