The Greenish Willow-Warbler
Phylloscopus viridanus Blyth, J.A.S.B., xii, p. 967 (1843) (Calcutta). Acanthopneuste viridanus. Blanf. & Oates, i, p. 414.
Vernacular names. Inruite (Kacha Naga).
Description. Similar to the Green Willow-Warbler but much browner above and much less yellow below; the wing-bar on the median coverts is wanting and the second is often obsolete.
Colours of soft parts and Measurements as in A. n. nitidus; wing 55 to 65 mm.
Distribution. Breeding in N.E. Europe, West Siberia to Turkestan, Tian-Schan, Tibet, Kashmir and Garhwal to Sikkim and Hills of Northern Assam. In Winter South to Assam and practically the whole of India and Ceylon with the exception of Sind and Western Rajputana.
Nidification. This Warbler breeds in Kashmir and Garhwal from the middle of June to the middle of July, in Sikkim and the Assam Mountains from the end of May to June, whilst in Tibet few eggs will be found before July. The nest is a large untidy ball of grass and moss, mixed sometimes with a few roots and dead leaves. The lining is of hair, either of goats, yaks or horses, occasionally mixed with fur. The nest is always placed on the ground; generally on a steep bank in among juniper or other scrub, ferns or grass; occasionally quite in the open and once I found a nest in among mossy boulders on a road-side. The eggs, four in number, are pure white, of a soft texture and almost glossless ; thirty-six eggs average 15.3 x 11.9 mm.: maxima 16.8 x 12-0 mm. and 16.0 x 12.6 mm.; minima 13.2 X 10.3 mm.
Habits. The Greenish Willow-Warbler is a bird of well-wooded areas, though during the breeding-season it may be found in open places if surrounded by woods. In Winter it keeps principally to the higher branches of trees of some size, though the smaller Acacias which attract so many insects are a favourite resort.
