Smart-looking dark thrush with a distinctive pale crescent on the chest; male’s is bright white, female’s is dingier. Adult blackish overall with frosty pale wing edgings. Immature in autumn–winter has a much duller collar. Bill is duller yellow than Eurasian Blackbird, with a dark top edge and tip. Rather shy, flying into cover or far away over slopes when disturbed. Breeds in open highland habitat, including moorland, alpine meadows, rocky mountain sides, and conifer stands. Migrants can turn up in fields and open farmland. Sometimes associated strongly with junipers, especially in non-breeding range. Song is pleasant but simple and repetitive; calls include a low “taktaktak” and a buzzy “zrrp, zrrp.”
