Blue Rock Thrush

The blue rock thrush is a starling-sized chat, 21 to 23cm long with a long slim bill, formerly placed in the thrush family. It breeds in southern Europe, north-west Africa, and from Central Asia to northern China and Malaysia. The breeding male of the nominate form is unmistakable, all blue-grey apart from darker wings; females and immatures have dark brown upperparts and paler brown scaly underparts (Wikipedia, general species account).

The male of the subspecies philippensis has rufous-chestnut plumage from the mid-breast down to the undertail. The male sings a clear, melodious song, louder than the rock thrush's, with a short song and a long song of melodious whistles, trills and burry notes. It nests in rock cavities and walls and usually lays three to five eggs. The account opened does not name Bhutan.
