The Kowari (Dasyuroides byrnei), also known as the Brush-tailed Marsupial Rat, Byrne's Crest-tailed Marsupial Rat, Bushy-tailed Marsupial Rat and Kawiri, is a small carnivorous marsupial native to the dry grasslands and deserts of central Australia.

[edit] Description

The Kowari is 16.5-18 cm long with a 13-14 cm tail. Its diet consists mainly of insects and spiders, but probably also small lizards, birds or rodents.[1] It is known as a voracious predator. It lives in underground burrows, singly or in small groups. It emerges to hunt among grass tussocks for food. It breeds in winter, from May-October, and gives birth to litters of 5-6 young after a gestation of 32 days.[1]

The Kowari is coloured ashy-grey, and its distinguishing feature is the brush of black hairs on the end of its tail, which differs from that found in the mulgaras (Dasycercus) in that it completely encircles the end of the tail.[3]

[edit] Habitat

The Kowari is found in stony desert areas of the Lake Eyre drainage basin, in north-eastern South Australia and southwestern Queensland. West of Lake Eyre it is declining, and is now possibly extinct in this area.[4]

[edit] Classification

The Kowari is the only member of its genus. The genus name, Dasyuroides, indicates that it resembles Dasyurus, the quolls. First described in 1896 by Sir Walter Baldwin Spencer, it was for some time included in the genus Dasycercus.

The Kowari is a member of the family Dasyuridae, and is most closely related to the Mulgara.

Two subspecies of the Kowari are recognised:[3]

  • D. b. byrnei, found in the north-eastern part of the range
  • D. b. pallidior, found in the south-western part of the range
