(927) Suya crinigera cooki.
Harington's Brown Hill-Warbler.
Suya crinigera cooki Harington, Bull. B.O.C., xxxi, p. 109 (1913) (Thayetmyo).
Vernacular names. None recorded.
Description. Differs from S. c. crinigera in having the black bases to the feathers of the breast entirely concealed in Summer; the striatums on the upper plumage are much less developed or entirely absent; the colour of these parts is much more grey-brown and there is practically no rufous tinge; below the colour is paler and less rufous.
Colours of soft parts as in S. c. crinigera.
Measurements. Wing 53 to 60 mm.; tail 71 to 83 mm.; tarsus about 22 mm.; culmen 11 to 12 mm.; the difference between the Summer and Winter tail in length is but slight.
In Winter the plumage is darker and the striations more apparent and the fulvous below a little darker.
Young are paler and slightly more fulvous and very much more yellow below.
Distribution. North and South Shan States, Hills of Karenni and Central Burma, West to Thayetmyo; Yunnan and Annam. Two specimens from Annam are very dark in comparison and much more rufous—in fact, very close to my assamica.
Nidification. Similar to that of the other races of this species.
Habits. Those of the genus.
