Monticola solitarius (Linnaeus, 1758) |
The blue rock thrush (Monticola solitarius) is a species of chat. This thrush-like Old World flycatcher was formerly placed in the family Turdidae. It breeds in southern Europe, northwest Africa, and from central Asia to northern China and Malaysia.
The blue rock thrush was described by Carl Linnaeus in 1758 in the 10th edition of his Systema Naturae under the binomial name Turdus solitarius. The scientific name is from Latin. Monticola is from mons, montis "mountain", and colere, "to dwell", and the specific epithet solitarius means "solitary".
The rock thrush genus Monticola was formerly placed in the family Turdidae but molecular phylogenetic studies have shown that the species in the genus are more closely related to members of the Old World flycatcher family Muscicapidae.
There are five recognised subspecies:
There is a proposal to split Monticola solitarius into two species: a western taxon comprising M. s. solitarius and M. s. longirostris and an eastern taxon with M. s. philippensis, M. s. pandoo and M. s. madoci.
The blue rock thrush is a starling-sized bird, 21–23 cm (8.3–9.1 in) in length with a long slim bill. The breeding male of the nominate subspecies 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. The male of the subspecies M. s. philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. Both sexes lack the reddish outer tail feathers of rock thrush.
