Medium-sized thrush-like bird, often seen on mountainsides, sea cliffs, quarries, ruins, and even towns. Males usually unmistakable: western birds are dark blue all over, but may appear all dark at a distance; eastern birds are blue with orange underparts. Females dark brown above, finely barred below. Long bill, wings, and tail make for a distinctive and very different shape than Rufous-tailed Rock-Thrush. Song is melodic and blackbird-like.
