Appearance:

Diagnostic, squarish head profile with flat crown, high bill base, steep forehead in all plumages. Male unmistakable with white and orange-buff underparts, white head with dark eye-patch, black collar and black back. Female mottled brown, but distinguished by head profile and blue wingbar with white edges. Identifiable at a distance by its habit of holding the tail raised clear of the water like a dabbling duck.

Sound:

Male seldom heard. Display sound probably a clear whistle rising slightly and then falling in pitch, a bit like Golden Plover. Female more noisy with indistinct guttural sounds.

Appearance:

Compact built bird attached to rocky habitat. Differs in all plumages from Blue Rock-thrush, Monticola solitarius by short, rufous tail and shorter bill. Primary projection very long, and wing-tips almost reaches end of tail in perching birds. Male in breeding plumage unmistakable with blue-grey head, orange-buff underparts and white patch on back (variable). Male resembles female and immature birds when not in breeding plumage, but can sometimes be sexed by partly grey head and hints of white on back. General characteristics of non-breeding plumage are greyish brown and speckled upperparts, and orange-buff, vermiculated underparts. Then told from female Blue Rock-thrush by aforementioned different build, bill and tail, and also by paler throat-sides/breast and warmer rufous flanks. Posture usually upright with giss resembling more a wheatear than a thrush.

Sound:

Alarm call a soft, wheatear-like "peeu", often accompanied by harder "tek" calls. Also a very nasal, drawn-out wheeze. Song varied and pleasing, and often very difficult to tell from Blue Rock-thrush. It is generally softer, more varied and the deeper notes are less tremulous and vibrating. A higher proportion of the song is in the higher register, with fewer lower fluting sounds, and more mimicry. Both sexes sing, but females less than males.
