Measurements. Wing 86 to 89.5 mm.; tail about 78 mm.; culmen 12 to 13 mm. long but only 9 to 9.5 mm. deep at the base; tarsus about 25 mm.
Distribution. Hills South of the Brahmaputra, Chin, Kachin Hills and hills of Central Burma.
Nidification. Cannot be distinguished from that of the Red-headed Parrot-Bill in any way. 38 eggs average 20.7 × 16.2 mm.
Habits. Similar to those of P. r. bakeri, but is perhaps not found at such low elevations. It occurred in the low hills round Margharita in Assam, but here the close proximity of the snow-line gives an avifauna and flora at 700 to 1,000 feet which obtains elsewhere at more than twice this height. It is curious that though all the Red-headed forms of Parrot-Bill consort together when feeding, none of the red-headed birds are ever found mixing with those of the grey-headed races.
