Description

The Pale-headed Snake is a medium-sized (up to 90 cm long), largely tree-dwelling snake. The back, side and tail is a uniform light brown or grey with a white or cream band on the nape, bordered by a narrow blackish bar which may be solid, or broken in the middle. The top of the head is grey, and may have a series of black spots,which are most prominent along the edge of the white nape. The lips may have black vertical bars. The belly is creamy grey sometimes with darker flecks.

Distribution

A patchy distribution from north-east Queensland to the north-eastern quarter of NSW. In NSW it has historically been recorded from as far west as Mungindi and Quambone on the Darling Riverine Plains, across the north west slopes, and from the north coast from Queensland to Sydney. A small number of historical records are known for the New England Tablelands from Glenn Innes and Tenterfield; however, the majority of records appear to be from sites of relatively lower elevation. Although the Pale-headed snake distribution is very cryptic, it now appears to have contracted to a patchy and fragmented distribution.

Habitat and ecology

  • The Pale-headed Snake is a highly cryptic species that can spend weeks at a time hidden in tree hollows.
  • Found mainly in dry eucalypt forests and woodlands, cypress forest and occasionally in rainforest or moist eucalypt forest.
  • In drier environments, it appears to favour habitats close to riparian areas.
  • Shelter during the day between loose bark and tree-trunks, or in hollow trunks and limbs of dead trees.
  • The main prey is tree frogs although lizards and small mammals are also taken.
  • The Pale-headed Snake is relatively unusual amongst elapid snakes in that it is well adapted to climbing trees.
