Warringah is home to two species of bandicoots, the more common Long-nosed Bandicoot (Perameles nasuta) and the threatened Southern Brown Bandicoot (Isoodon obesulus).
The Southern Brown Bandicoot is a medium-sized marsupial with a long tapering snout and naked nose. It has small round ears and eyes. It is dark grey in colour with golden-brown
flecks and a creamy white underbelly.
Bandicoots are nocturnal animals and live in a wide range of habitats. They usually hide during the day in their nest which may consist of a hollow log or crevice or low lying vegetation.
The Southern Brown Bandicoot is an omivore that forages for food shortly after dark or before dawn. It eats grubs, spiders and worms and other garden pests. It prefers sandy soil with scrubby vegetation and areas of low ground cover. Small conical holes in the ground are a sign of bandicoots.
The Southern Brown Bandicoot is sometimes found in Warringah suburbs adjoining Ku-ring-gai Chase and Garigal National Parks.
