Finaly, she sits down with her tail brought forward between her legs and squats with her back rounded. The single newborn emerges from the cloaca, rupturing the fetal membranes in the process, and climbs into the pouch with no assistance from its mother, where it grows for the next ten to twelve months. Behavior These arboreal animals have powerful arms, comparatively short hind legs, and long, curved claws. They usually take little hopping steps, in which the two forelegs and the two hind legs alternately touch the ground. Members of this species also hold their tails off the ground.
Most tree kangaroos appear to be solitary.
They primarly live in trees or closed forest areas over mountainous ranges. They are restricted to the rainforest. Those tree kangaroos still suriving in highland forest have had to contend with logging operations which markedly limit their distribution. Their survival seems to have only been assured by the reasonable numbers in National Parks and reserves and also by the almost complete absence of any large tree-climbing predators or competitors. Goodfollow's tree kangaroos are listed as vulnerable by the IUCN, and there are no accurate estimates of the number of each species which survives in the wild.
