The Brown Tree- Warbler, Jerd.

Coloration. Upper plumage brown, with a tinge of green ; wings and tail dark brown, edged with olive-yellow; lores and behind the eye blackish ; a narrow but distinct supercilium from the nostrils to the end of the ear-coverts buff; sides of the head and the whole lower plumage buff, paler on the chin, throat, and abdomen ; under wing-coverts and axillaries bright sulphur-yellow.

Iris dark brown; legs and feet brownish black, soles pale; bill dusky brown {Butler).

Length about 5; tail 1.8 to 2.1; wing 2.2 to 2.5; tarsus .8 ; bill from gape .5; the first primary .6; the second primary is equal to the seventh, or sometimes rather shorter.

This species differs from the European Chiffchaff in not being yellow beneath, except on the axillaries and under tail-coverts. In faded plumage it may be confounded with P. sindianus; but Hume points out (l. c.) that these two birds may at all times be separated by the shape of the first primary. I have been able to examine only one specimen of P. sindianus, but I could not detect in its first primary any difference of shape from that of P. tristis. It is seldom, however, that P. tristis is so very faded as not to exhibit some yellow on its axillaries and under wing-coverts, and this character will suffice to separate it from P. sindianus, as a rule.

Distribution. Summers in the higher portions of the Himalayas in Kashmir. In winter this species is found over the whole of India from Sind to Dacca, and south to about the latitude of Bombay. Some birds remain in the Himalayas, at lower levels, throughout the winter. The nest has not yet been found within our limits, but has been obtained in Siberia.
