A bird of the passerine family; the male looks like a male blackbird but with a white crescent on his chest and silver reflections on his wings which are highly visible in flight. The female is brown and has a much less visible crescent on her chest, her underside is slightly scaly and her wings are silvery.
Its song is characterised by a repetitive chirp of plaintive notes and an explosive “chak-chak”.
The bird builds its nest on the edge of the forest or in a conifer in an Alpine pasture where it lays 4 or 5 greenish blue eggs with brown speckles in May/June.
