About Prunella collaris (Scopoli, 1769)
This is a robin-sized bird, 15 to 17.5 cm (5.9 to 6.9 in) in length, which is slightly larger than its close relative the dunnock. It has a streaked brown back, an appearance somewhat similar to a house sparrow. However, adult individuals have an all-grey head and red-brown spotting on their underparts. It has the fine, pointed bill characteristic of an insectivore. Males and females have similar overall appearance, though the male may show more contrasting markings. Young birds have browner heads and underparts. This species occurs across the mountains of southern temperate Europe, Lebanon, and Asia, found at elevations above 2,000 m (6,600 ft). It is mostly non-migratory (resident), but moves to more widespread lower latitudes for the winter. A small number of wandering individuals are rare vagrants as far north as Great Britain. It inhabits bare mountain areas that have some low vegetation.
