Genus PETROPHILA

The genus Petrophila contains those Rock-Thrushes which have a short wing and a comparatively long tail. The males have the under wing-coverts and axillaries entirely of one colour and the lower plumage blue, chestnut, or black, or a combination of these colours. The females have the lower plumage squamated or irregularly barred and the under wing-coverts and axillaries also barred.

The Rock-Thrushes frequent open rocky ground and are generally solitary in their habits. They make their nests in holes of walls and rocks.
