THE WHITE-RUMPED SPINE-TAIL.
Length, 4.25 ; wing, 5 ; tail, 1.5. Bill black; irides dark brown ; legs and feet livid.
Above, the whole plumage glossy green-black, except the rump, which is pure white, and the upper tail-coverts which are also white, the outermost being tipped black ; the throat, cheeks, and breast pale grey, gradually passing into black on the sides of the body; belly and under tail-coverts pure white.
Tickell was the first naturalist who observed this species, and he states that, in Central India, " it haunts open cultivated grounds in the midst of forest; also the cleared patches on the sides and summits of hills."
