Distribution. Nepal Terai, Sikkim and Eastern Bengal to Eastern Assam, North of the Brahmapootra; Travancore and Ceylon.

Nidification. The Black-crested Baza breeds from April to June in Northern India and in February, March and April in Travancore, whilst Stewart also took one nest with eggs on the 4th of July in that Province. The nest, which is placed on either small saplings or lofty trees, is well and compactly made of small twigs lined with grass or fibre, with an over-layer of green leaves. The tree selected seems to be always one in deep forest and, in preference, one near water. The eggs, two or three in number, are grey-white, generally much stained with tan-yellow. In shape they are broad obtuse ovals and twenty-four average 37.4 x 31.1 mm.,: maxima 46.0 x 31.0 and 39.1 x 32.1 mm.; minima 34.9 x 29.5 and 36.5 x 28.9 mm.

Habits. This beautiful Raptore is a forest bird but likes best forests with wide streams running through them or with broad glades and casual open spaces. They were not uncommon in Upper Assam and could often be seen in small parties of from three to five, sailing round in small circles, just over the tree-tops, every now and then flapping along like a party of Crows. Their movements are very leisurely but they are generally shy birds and difficult to approach within shot, though occasionally they seem very obtuse and lazy. This, however, is only when the sun is hot and glaring, for they are very crepuscular in their habits as their beautiful lustrous eyes would indicate. They live- principally on insects—locusts, grasshoppers, Cicadae and termites especially—but they also sometimes eat bats, mice, shrews, lizards and tree-frogs; Their1 cry is a quivering plaintive' scream, like the softened squeal of the Kite and is uttered both on the wing and when seated.
