The Tree Kangaroo

There are 14 known species of tree kangaroo that are found in Australia, Papua New Guinea, and Indonesia. Tree kangaroos live in lowland rainforests and cloud forests at around 11,000 feet. Deforestation and illegal hunting are the main causes for their endangered status with IUCN. Due to the nearly 90% habitat loss tree kangaroo populations have plummeted by nearly 80%!

First the Stats…

Scientific name: Dendrolagus
Weight: Up to 32 lbs.
Height: 30 inches plus their up to 34 inch tail
Lifespan: 15 years (in the wild) | 20+ years (in captivity)

Now on to the Facts!

1.) They spend most of their lives in trees making them arboreal.

2.) These critters will typically lick their forearms to aid in cooling themselves on hot days.

3.) While skilled at climbing trees, these kangaroos aren’t as skilled at moving around (as other roos do) while on the ground.

4.) These roos are diurnal (active during the day).

5.) Tree kangaroos eat leaves, shoots, flowers, bark, eggs, and even the occasional small bird.

But wait, there’s more on the tree kangaroo!

6.) Pythons and wild dogs are the main predators of these kangaroos.

7.) The tree kangaroo is solitary and territorial. They patrol a large area that overlaps with nearby female territories.

Did you know…?
Tree kangaroos can jump distances of up to 30 feet between the trees and also safely land on the ground from a height of up to 60 feet!

8.) Tree kangaroos mate during monsoon season. Talk about a stormy relationship. Males mate with couple of females each season, but do not have harems.

9.) Pregnancy lasts 40 – 45 days and results in a single baby, called a joey, that is underdeveloped and crawls into their mother’s marsupial pouch to continue to grow.

10.) At around 8 months the joey leaves the pouch to begin exploring, but will return to their mother’s pouch for rest and milk. At around 10 months the joey is developed enough to leave their mother and begin leading a solitary life.

Critter Man

With over 41 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge.I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or air.I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!Let it be said that I have been oft times accused of loving animals more than I love people. I can neither confirm nor deny this.
