7-11-2023 MONTE CORONA, VALENCIA - BLUE ROCK THRUSH (FEMALE) (Monticola solitarius)

Widespread throughout Southern Europe, North Africa and Southern Asia, the blue rock thrush is a large sized chat which is predominantly sedentary, although a partial migrant within specific narrow geographical areas.

Although named as a thrush this bird is actually a chat. The adult male of the nominate race has a dark blue body with darker brown coloured wings and tail. It is the same size as a starling and has a long thick spiky slate grey bill. From a distance the male can appear to be black although the head is a bright blue. The adult female is a dull browny blue grey on the upperparts extending from the forehead, across the crown and down the back. The face is pale and mottled with thin brown markings almost with the appearance of scales, which run down to the mid chest area. From the mid chest to the lower belly the body is pale with horizontal dark brown bars across the belly from flank to flank. Juveniles are similar to females but slighter darker with bolder underpart markings, although there is no blue colouration or shading on the plumage whatsoever. There are a total of five sub-species of blue rock thrush. The colour and patternation differences from the nominate of four of the sub-species are subtle, however the adult male of the sub-species Monticola solitarius philippensis is strikingly different, in that whilst the body of the bird is predominantly a bold blue, the breast, belly and undertail areas are a contrasting rufous to chestnut brown shade.

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 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.

The male blue rock thrush sings a clear, melodious call that is similar to, but louder than the call of the rock thrush.
