Blue Rock Thrush

The blue rock thrush is a starling-sized, thrush-shaped member of the Old World flycatcher family, measuring 21–23 centimetres. It has a long, slender bill. A breeding male of the nominate western form is blue-grey apart from darker wings, whereas females and immature birds are dark brown above with paler, scale-patterned underparts. The eastern subspecies philippensis differs: its male has rich rufous-chestnut plumage from the middle of the breast to the undertail. Both sexes lack the reddish outer tail feathers of related rock thrushes. (Wikipedia, general species account)

The species breeds from southern Europe and northwestern Africa east through Central Asia to northern China and Malaysia. The eastern subspecies philippensis ranges from eastern Mongolia and Sakhalin south through Japan, northeastern China, the northern Philippines and Indonesia. Some populations are resident or make only altitudinal movements, while other Asian birds migrate to India, Southeast Asia or sub-Saharan Africa. Males advertise with clear, melodious songs made from whistles, trills and rougher notes; longer songs are somewhat more frequent among Asian birds. (Wikipedia, general species account)
