The young tarsiers can climb after two days and jump after four. Normal locomotor patterns ensue at approximately nineteen days. Males and females are usually seen together. They show little fear of other animals, especially humans, unless quick movement is made. When in danger, Tarsius syrichta lets out a high pitched squeak.
Tarsiers are arboreal and nocturnal.
They spend the day hiding in dense vegetation and sleeping in trees. Habitat The Philippine tarsier is found in areas of tall grasses, bushes, bamboo shoots, and small trees in tropical rainforests. They enjoy the canopy of the jungle, leaping from limb to limb. Captive breeding efforts have been started but to date all have been unsuccessful. Tarsiers have suffered greatly from hunters and trappers who shake the animals out of their trees or chop down the branches of the trees in which they live.
