Calamanthus cautusHylacola cautusSericornis cautus The shy heathwren (Hylacola cauta) is a species of small bird in the family Acanthizidae, endemic to Australia.

They have a white eyebrow, tail tip and patch on the flight feathers, and a black bill.

Ranging from near West Wyalong in New South Wales to the Murchison River in Western Australia.

[8] In New South Wales, they are found in two isolated populations: one between Leeton, Willandra National Park, Nymagee and West Wyalong; and the other from Balranald to Trentham Cliffs.

Within the state they are seen as a threatened and vulnerable, largely due to human-wrought habitat loss, and predation by foxes and cats.
