Origin of rock thrush
Examples from the Web for rock thrush
The rock-thrush is more alpine and confined (here as elsewhere) exclusively to the higher sierra.
The rock-thrush is also endowed with a lovely wild song, quite low and simple, but replete with a fine high-tops quality.
On May 18 we obtained here a nest of the rock-thrush with five beautiful greenish-blue eggs.
The chief bird-forms of the high sierra were ravens and choughs, ring-ouzels, rock-thrush and black-chat (Dromolaea leucura).
