88 BIRDS OF BRITISH BURMAH. 
towards the nape darker than the other parts; wings and wing-coverts 
dark brown_, edged with yellowish green^ the median and greater coverts 
with conspicuous yellowish tips,, forming two wing -bars ; the quills tipped 
conspicuously with whitish; tail brown, edged with yellowish green on 
the outer webs ; lores and ear-coverts mixed brown and yellow ; lower

Length 4 inches^ tail 1*8, wing 2*1^ tarsus '7, bill from gape '5 : the 
second primary is generally intermediate in length between the sixth and 
seventh ; the first primary measures about '5 inch in length. The female 
is considerably smaller than the male. 
A closely allied species is P. humii, which is likely to occur in Burmah. 
In this the second primary is generally intermediate between the eighth 
and ninths the eye-stripe is bufi" and the upper wing-bar is very indistinct 
and nearly absent in some specimens. Another species, P. mandellii, also 
likely to occur in Burmah, is closely allied. It is of very rich coloration ; 
its head is blackish brown and the legs are pale yellow. 
The Yellow-browed Willow-Warbler is one of the commonest birds of 
this genus in Burmah. It is found abundantly in every portion of Pegu. 
Mr. Blyth records it from Arrakan ; and I have also received specimens 
from that Division collected by Mr. Shopland. Mr. Davison found it 
common in Tenasserim as far south as Mergui ; and Capt. Bingham 
observed it in the Thoungyeen valley. Capt. Wardlaw Ramsay procured 
it in the Karin hills up to altitudes of 2500 feet. It is, of course, only a 
winter visitor to Burmah. I have obtained it from October to April. 
This Warbler is found in winter throughout the Indo-Burmese countries, 
Assam, Bengal and Sikhim. It is also found in Southern China. It 
summers in Siberia. Occasionally it wanders into Europe. 
This small bird is one of the first migrants to arrive in Burmah and 
almost the last to leave, notwithstanding the long journey it has before it 
to the wilds of Siberia. It is a cheerful and active bird, frequenting alike 
large trees and low hedges in pursuit of its insect food. Mr. Seebohm 
found its nest in Siberia. It was composed of dry grass and moss, and 
lined with reindeer-hair. The structure was semidomed, and was built in 
a slight tuft of grass, moss and bilberries, and it contained six eggs, white 
spotted with reddish. 
It may be noted here that the account of the nidification given by 
Mr. Hume Nests and Eggs,^ p. 364) under the title of R. superciliosus 
I'eally relates to the allied P. humii.
