Distribution. Himalayas from Naini-Tal to E. Assam, North and South of the Brahmaputra, Manipur, Lnshai, Chittagong Hill tracts and Chin Hills.
Nidification. The Blue-winged Siva builds a nest which is a small, neat edition of that of Leiothri.v lutea; i. e. it is a small cup made of leaves, grasses, moss and roots, lined with very fine roots and fine grasses, usually of a very dark colour. The majority of nests are found low down in bushes only a few feet from the ground but others may be taken higher up in trees. Wherever it is placed, however, it is sure to be well hidden, unlike that oi LeiotJirix which is well exposed to view. The epgs vary from two to four, often two only, and are like those of l^iva strif/u/a; in shape they are very regularovals and 24 eggs measure on an average 1 8'4 x 14- 1 mm. The breeding season is May and June.
Habits. This Siva may be found anywhere between 3,000 and 8,000 feet but is most common and breeds freely between 4,000 and 6,000 feet. They consort in flocks and feed both on the higher trees and in amoTigst the brushwood and seem particularly fond of the tangles of raspberry and blackberry vines so common throughout their haunts. They fly well and fairly quickly.
