The Alpine Accentor , Prunella collaris, is a small passerine bird found throughout the mountains of southern temperate Europe and Asia at heights above 2000m. It is mainly resident, wintering more widely at lower latitudes, but some birds wander as rare vagrants as far as Great Britain.
It is a bird of bare mountain areas with some low vegetation. It builds a neat nest low in a bush or rock crevice, laying 3-5 unspotted blue eggs.
This is a Robin-sized bird, slightly larger than its relative, the Dunnock. It has a streaked brown back, somewhat resembling a House Sparrow, but adults have a grey head and red-brown spotting on the underparts. It has an insectivore's fine pointed bill.
Sexes are similar, although the male may be contrasted in appearance. Young birds have browner heads and underparts.
