Vernacular names. None recorded.
Description. Upper plumage deep smoky-brown, almost blackish, sometimes faintly tinged with olive; wings and tail dark brown, the feathers edged with olive-brown; a narrow supercilium dull green ; sides of head dull buff and brown; whole-lower plumage dull oil-green, the breast and flanks suffused with dusky-brown.
Colours of soft parts. Iris brown; bill black, the lower mandible horn3'-brown ; legs and feet ochraceous-green.
Measurements. Total length about 110 mm.; wing 52 to 60 mm. (Tibet, one, 65 mm.); tail 42 to 46 mm.; tarsus about 21 mm-; culmen 10 to 11 mm. Second primary equal to tenth.
Distribution. Nepal and Tibet to Eastern Assam, North of the Brahmaputra. In Winter South throughout Assam and Eastern Bengal. I found it very common at Dacca in January and February.
Nidification. Three eggs taken at Rhamtso, Tibet, at almost 14,000 feet elevation on the 4th August, 1921, were sent me with the remains of a skin of this species. They are like exceptionally heavily marked eggs of P. affinis. They measure 15.0 x 12.0 mm., 14.6 x 12.2 mm. and 15.0 x 12.1 mm. No nest was sent and I could obtain no description of it.
Habits. In Summer the Smoky Willow-Warbler is found in the higher ranges, certainly up to 15,000 and probably breeding between 12,000 feet and that height. In Winter it is very aquatic in its Habits. Stevens found it keeping much to bushes and reeds in swampy places, whilst in Eastern Bengal I found it keeping almost entirely to bushes on Islands in the Megna, Brahmaputra and other large rivers.
