The Aberrant Warbler.

Neornis flavolivacea Blyth, J. A S B., xiv, p. 590 (1845) (Nepal) ; Blanf. & Oates, i, p. 433 (part.).

Vernacular names. None recorded.

Description. A narrow supercilium from the nostrils to the nape yellow; lores and a line through the eye brown; upper plumage and exposed parts of the wrings and tail dull olive-green -y concealed parts of wings and tail brown ; sides of the head mottled yellow and brown; lower plumage fulvous-yellow, darker and suffused with brown on the sides of the breast and flanks; axillaries and under wing-coverts pale lemon-yellow.

Colours of soft parts. Iris hazel; bill above horny-brown, below paler yellowish brown; legs and feet light yellowish brown.

Measurements. Total length about 105 mm.; wing 53 to 56 mm.; tail 4S to 56mm.; tarsus about 22mm.; culmen about 10 to 11 mm.

Young birds are much brighter and more yellow below than adults.

Distribution. Sutlej Valley to Nepal, Sikkiin, Bhutan, Western Assam, North of the Brahmaputra, Garhwal and Kuinaon.

Nidification. Mr. S. L. Whymper found this bird breeding in Kumaon at 10,000 feet, and Mr. B. B. Osmaston took nests in the Tons Valley at about 11,000 feet. The nests are described as being domed, made outwardly of dry grass with a lining first of dry leaves and then of feathers. They are placed in tufts of grass on hill-sides.

The eggs are rather long ovals, pale to deep terra-cotta in colour and they measure from 17.0 x 12.4 nun. to 18.5 x 13.1 mm. Mr. Whymper took his nests in August and Mr. Osmaston his in June.

Habits. Practically nothing on record. Stoliczka found this Warbler as low as 6,000 feet in the Sutlej Valley but farther west it seems never to be found much under 8,000 feet even in Winter. It is a resident bird but moves vertically to some extent with the seasons.
