| Monticola solitarius (Linnaeus,, 1758) |
The Blue Rock Thrush or Blue Rock-Thrush (Monticola solitarius) is a member of the thrush family (Turdidae).
This species breeds in southern Europe and northwest Africa, and from central Asia to northern China and Malaysia.
The European, north African and southeast Asian birds are mainly resident, apart from altitudinal movements. Other Asian populations are more migratory, wintering in sub-Saharan Africa, India and southeast Asia. This bird is a very uncommon visitor to northern and western Europe.
Blue Rock Thrush breeds in open mountainous areas, usually higher than the breeding zone of the related Rufous-tailed Rock Thrush. It nests in rock cavities and walls, and usually lays 3-5 eggs. An omnivore, the Blue Rock Thrush eats a wide variety of insects in addition to berries.
This is a largish thrush, 21-23cm in length with a long slim bill. The summer male is unmistakable, with all blue-grey plumage apart from its darker wings. Females and immatures are much less striking, with dark brown upperparts, and paler brown scaly underparts. Both sexes lack the reddish outer tail feathers of Rock Thrush.
The male Blue Rock Thrush sings a clear, melodious call that is similar to, but louder than the call of the Rock Thrush.
