[edit] Distribution

South coast of Western Australia (coastal heaths east of Albany).

[edit] Taxonomy

This is a monotypic species,[1] which was thought to be extinct until a small population (about 100) was rediscovered at Two Peoples Bay, 35 km east of Albany, in 1961. The area was established as a nature reserve in 1967, to preserve the habitat for this species, whose current status is Vulnerable.

[edit] Habitat

Temperate shrubland and low, thick coastal scrub.

[edit] Behaviour

  • Very elusive birds, normally only heard deep in the scrub. Almost flightless, the bird runs fast on its strong legs, moving through the thick scrub, climbing or jumping up to the lower branches of trees, but can fly a few metres on its small, rounded wings when needed.
  • Nesting: the breeding season is in the winter, beginning in May or June, when predators such as goannas and snakes are inactive. The female builds a dome-shaped nest with a side entrance, in the thick sedge, close to the ground. She lays one large egg, pale pinkish-buff in colour, with speckles. She incubates alone for about 38 days, which is about twice as long as other passerines. Total care of the nestling is by the female. The nestling fledges in 3-4 weeks, but may stay close to the mother for several months.
  • Voice: a very loud, strong call. Listen to the call below.
