Shy Heathwren

The Shy Heathwren, Hylacola cauta, is a diminutive and elusive bird, a member of the Acanthizidae family, and uniquely Australian. This bird is distinguished by its cocked tail with a chestnut rump that darkens towards the tip. The plumage is a tapestry of white with brown streaking on the underside, and a greyish-brown hue adorning the back and crown. A striking white eyebrow, tail tip, and patch on the flight feathers contrast with the black bill. The eyes range from brown to yellowish-brown, while the legs are a slate-brown. Females and immature birds present a slightly duller palette, with the young sometimes showing a fawn coloration below.

Identification Tips

Adult Shy Heathwrens measure between 12 to 14 centimeters in length. To identify this species, look for the characteristic white eyebrow and the chestnut rump. The white patch on the flight feathers is also a key feature, along with the cocked tail posture.
