The blue rock thrush (Monticola solitarius) is a chat species, reminiscent of a thrush, with a starling-like stature, measuring 21–23 cm in length. The male of the nominate subspecies is predominantly blue-grey, save for darker wings, presenting a striking appearance. Females and immature birds are less vivid, with dark brown upperparts and paler, scaly brown underparts. The male of the subspecies M. s. philippensis is distinguished by rufous-chestnut plumage from the mid-breast to the undertail, a feature absent in both sexes of the rock thrush.
To identify the blue rock thrush, look for the male's unmistakable blue-grey plumage and the female's less conspicuous brown tones. The male M. s. philippensis can be recognized by its rufous-chestnut lower half. Both sexes lack the reddish outer tail feathers seen in rock thrushes.
This bird favors open, mountainous regions where it can nest in rock cavities and walls.
The blue rock thrush breeds across southern Europe, northwest Africa, and from Central Asia to northern China and Malaysia. It is a resident bird in Europe, north Africa, and southeast Asia, with some populations exhibiting altitudinal migration. Other Asian populations are migratory, wintering in sub-Saharan Africa, India, and southeast Asia. It is a rare visitor to northern and western Europe.
The blue rock thrush is an omnivore, consuming a varied diet of insects, small reptiles, berries, and seeds. It breeds in its preferred mountainous habitats, laying 3-5 eggs per clutch.
The male's song is a clear and melodious call, louder than that of the rock thrush, which can be heard echoing through its mountainous domain.
As an omnivore, the blue rock thrush has a diverse diet that includes insects, small reptiles, berries, and seeds.
The blue rock thrush is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline.
