white wing-bars. Lower plumage, yellowish white, dusky brown on 
the flanks. 
Iris, brown. Bill, dark brown above, yellowish horn-colour 
below, dusky at the tip. Mouth, yellow. Legs, yellowish brown. 
Habits, etc. This bird also is a winter visitor, and has much the 
same habits and note as Phylloscopus fuscatus ( page 86 ), to which it 
also bears a close general resemblance. The present species may, 
however, be distinguished by its very minute first primary (that of 
P. fuscatus being fully one-third the length of the wing), by the 
greenish tinge on its upper plumage, the yellowish tinge on its lower 
parts, and the presence of the yellowish white bars on the wings. 
These bars, however, are sometimes indistinct, or almost wanting, 
owing to the wearing away of the feathers. 
Distribution. Also recorded from Trang by Robinson and Kloss 
under the name of Phylloscopus borealis.

Description. Length, from 132 mm. (9.2 in.) to 152 mm. 
(Gin. ), according to season—the tail being longer in the winter. 
Upper plumage, earthy brown, darker on the head and paler on the 
rump, which has a fulvous tinge; a whitish supercilium reaching to 
just behind the eye. Lower plumage, whitish, with buff tinge; thighs, 
deeper buff; under side of tail feathers, with black bands near the tips. 
Iris, clear brownish yellow. Bill, brown, except base of lower 
mandible, which is pale flesh-colour. Legs, pale reddish yellow. 
Habits, etc. A resident species, and common along our subur- 
ban khlongs and other similar places with rushes and high grass grow- 
ing by the waterside. It is a slender little brown bird, with rather a 
long tail (hence the words hang 17, in the Siamese name, meaning 
“ tapering-tailed” ), and has a sibilant, almost insect-like, note of 
chree-chree-chree-chree repeated a great many times. 
Distribution. Reported also from Eastern and Northern Siam 
( Gyldenstolpe ).
