Description. The whole upper plumage and smaller wing-coverts bluish-grey, brighter on the head; median tail-feathers umber-brown, with a subterminal black band and a dark grey tip; the black gradually increasing in extent until the outermost feathers are nearly all black with grey tips; greater coverts next the back entirely chocolate-brown changing to black on the outer coverts, winglet and primary-coverts; primaries black broadly edged with bluish-grey; outer secondaries with darker grey edges and inner secondaries umber-brown, edged with black on the outer webs; lores and round the eye black; ear-coverts mixed bluish-grey and black ; lower plumage ashy-blue, tinged with vinous.
Colours of soft parts. Iris crimson; bill black; legs horny-brown.
Measurements. Total length about 230 mm.; wing 100 to 105 mm.; tail about 120 mm.; tarsus about 33 mm.; culmen about 20 mm.
Distribution. The Hills South of the Brahmaputra above 5,000 feet, Toropatu Peak, Dafla Hills. Nidification unknown.
Habits. This Sibia frequents only the higher ranges. In some parts of the Naga Hills at about 7,000 to 9,000 feet it is not rare and it wanders, probably only in winter, into Cachar and the Khasia Hills on the peaks and ridges between 5,000 and 6,000 feet. God win-Austen says that it is found in companies of about half-a-dozen, haunting the tops of rhododendron-trees, the flowers of which it searches busily for insects. The only call I heard was a very loud, shrill whistle, less musical than the notes of this genus generally are. They are extremely active birds like all the others.
