Male ad. (Siberia). Upper parts olive-green, the head darker ; rump yellow ; under parts white, washed with grey on the flanks ; mesial and superciliary stripes sulphur-yellow, well defined ; wings crossed by two distinct yellowish white bands ; bill brown, basal portion of lower mandible yellowish ; legs greenish brown, and dark brown ; 1st primary 0.7, shorter than the 2nd, which is equal to or a trifle longer than the 8th, the 4th longest. Culmen 0.1, wing 2.1, tail, 1.5, tarsus 0.67 inch. In the summer it is rather paler and the alar bars less clearly defined.
Hab. Asia from the Lena to Lake Baikal and south to the Himalayas, wintering in India, Burma, and south China ; occurs regularly on passage, on the western slopes of the Ural, and has occurred once in Heligoland and once in England.
Frequents pine and birch woods and bush covered valleys, and in its general habits has much affinity with the Goldcrest. Its call-note is a shrill prolonged tsii, and its song is melodious and varied and very loud for so small a bird. Its nest is placed on the branch of a tree near the stem, is oven-shaped, con¬structed of grass-bents and moss and lined with feathers and horse or cattle hair and its eggs which are deposited in May or June are white dotted and spotted with violet, ash-grey, and red, the spots being frequently collected round the larger end, and measure 14 by 11 to 15 by 10.5 millimetres (0.59 by 0.41 inch).
The form which breeds in the Himalayas has been separated specifically by Gatke (Phylloscopus newtoni) but after a careful comparison of specimens I fail to see even subspecific differences that are constant.
