red kangaroos

Red Kangaroos (a.k.a Macropus rufus) are the largest of all kangaroos and are only found in Australia, New Guinea. They are unusual mammals who are also the largest marsupials in the world! Red Kangaroos are endangered nocturnal animals. They are usually sleepy during the day and sits under the shade of a tree. During the night, they are very active.

The female is often called the "blue flyer" because of her blue-grey fur. In the eastern part males are usually red (pale red to brick red) and females a bluish grey, elsewhere, both sexes may be reddish/brown.

Anybody know why they are endangered?
