There are about 12 different species of tree kangaroo. Two species are found in northeastern Australia, and the rest of the species and subspecies are found on the island of New Guinea. Tree kangaroos are very difficult to study in the wild so their average lifespan is unknown, but it is likely years. However, in captivity they can live for more than 20 years! The oldest known tree kangaroo is 27 years old.
After the infant initially leaves the pouch at eight months, it will continue to return to the pouch to nurse. During the final phase, the young still nurses but never climbs completely into the pouch.
Young tree kangaroos are weaned when they are approximately 13 months old. They stay with their mothers until they are about 18 months old, when they disperse and establish a home range.
Little is known about the social behavior of wild tree kangaroos. Researchers believe that Matschie's tree kangaroos are fairly solitary animals. Females and males have non-overlapping home ranges, but a male's range will overlap several females' range. Researchers also believe that Matschie's tree kangaroos are polygamous and that males interact with several females. Males, however, appear not to establish harems, and females remain independent.
The only strong social bond these animals form is between mother and offspring. In captivity, if females are isolated from all other animals after becoming pregnant, offspring almost always survive. These observations show that Matschie's tree kangaroos are mostly solitary animals. All rights reserved. Common Name: Matschie's Tree Kangaroo. Physical Description. Unlike their close cousins, the tree kangaroo's arms and legs are approximately the same length.
Tree kangaroos also have much stronger fore-limbs to help in climbing the trees they inhabit. Size Length: cm Tail length: cm Weight: up to The Wondiwoi tree kangaroo is critically endangered possibly extinct with as few as 50 individuals remaining. Diet Living in the trees, the tree kangaroo eats mostly leaves and fruit, although they will also collect fruit that has fallen to the ground. The animals will also eat other items such as grains, flowers, sap, eggs, young birds, and even bark.
Bennett's tree-kangaroo Dendrolagus bennettianus on the branch of a tree. The Bennett's tree-kangaroo is a rare and vulnerable Arboreal marsupial, Australia. What are the main threats? The major threats facing tree kangaroo species are hunting and habitat loss. Tree kangaroos have been hunted for food by indigenous communities across their range.
For a number of species, this factor alone has contributed to a sharp decline in population numbers. We don't yet know whether fragmentation is a significant threat to the overall population but fragmentation and the need to travel between fragments increases the number of tree-kangaroos killed on roads or by dogs. If frightened tree-kangaroos tend to 'freeze' and blend in with their surroundings which characterises their main predator avoidance behaviour--hiding in plain sight, sometimes referred to as 'crypsis'.
This might be a good strategy to escape their natural predators such owls, eagles and pythons, but it is not a good strategy to escape ground predators such as dogs or dingoes. Tree-kangaroos are quite comfortable travelling across open ground and will readily cross roads during which time they are vulnerable to being killed or injured by vehicles. To help reduce the road-toll of tree-kangaroos and other wildlife, please drive no faster than the posted speed limit, be alert for animals crossing the road and perhaps drive a little more slowly and cautiously in areas that are sign-posted as tree-kangaroo crossing areas.
