Eastern Hare-Wallaby(Extinct Animal)

The eastern Hare wallaby was a small macropod, slightly larger and more slender than its surviving relative the Rufous Hare Wallaby. It had a body length of about 50 centimeters and a 33 centimeter long tail. Its fur color varied from black through brown to yellow with a grayish-white belly.

This species once inhabited the interior of New South Wales, Victoria and the Murray River region of South Australia. It was common in the level country between the Murray and Darling rivers, as well as the Liverpool Plains. Its preferred habitat consided of open plains and grasslands.

Very little is known about this wallaby today. It was a strictly nocturnal animal which led a solitary lifestyle. During the day it sat still in a well-formed 'seat', usually in the shelter of a saltbush or a tussock. If approached too closely, it would bound off at great speed. One wallaby was chased by dogs for 500 metres and suddenly doubled back and came back within 6 metres of John Gould and leapt over his head; it could jump 1.8 metres high.

The last known specimen of this species was a female collected in August 1889 in New South Wales. There were no further sightings of this species, even though researchers well into the 1930s were still uncertain of its extinction.

The cause of its extinction remains uncertain, as it died out before intensive agriculture was introduced throughout its distribution and before the red fox became common in its habitat. Several causes of its extinction have been suggested, including trampling of its grassland habitat by cattle and sheep, changed burning regimes, or predation by introduced.
