Measurements. Total length about 150 to 155 mm,; wing 62 to 70 mm.; tail 63 to 70 mm.; tarsus about 25 mm.; culmen 12 to 13 mm. Birds from the Himalayas are rather larger than those South of the Brahmaputra, having wings 65 to 70 mm. as against 62 to 64 mm. in the southern birds.

Distribution. Himalayas from Naini-Tal to E. Assam, North and South of the Brahmaputra, Manipur, Lushai, Chittagong Hill tracts and Chin Hills.

Nidification. The Blue-winged Siva builds a nest which is a small, neat edition of that of Leiothrix 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 of Leiothrix which is well exposed to view. The eggs vary from two to four, often two only, and are like those of Siva strigula; in shape they are. very regular ovals and 24 eggs measure on an average 18.4 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 amongst 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.
