(1711) Gyps indicus nudiceps.

THE NORTHERN LONG-BILLED VULTURE.

Gyps indicus nudiceps Stuart Baker, Bull. B. O. C., xlvii. p. 151 (1947) (Nepal). Gyps tenuirostris Hume, Str. Feath., vii, p. 326 (1878) (Nepal) Blanf. & Oates, iii, p. 323.

Vernacular names. Sagun (Beng.); Hogun (Assam); Gut (Lepcha).

Description. Differs from the preceding form in having the head and neck practically naked, having no hairy down on the crown and nape and either none or very little on the neck ^ the upper plumage is sometimes darker and browner and the underpays more brown and less fulvous ; the bill is more slender with a rather larger, more open nostril.

Colours of soft parts. Iris dark brown ; " bill brownish dusky horny; cere horny-black; skin of head and neck dark muddy tarsi and toes black; claws dusky and horny-black" {Hume).
Measurements. Wing 590 to 630 mm.; tail 237 to 256 mm.; tarsus about 110 mm.; culmen 66 to 68 mm.

Distribution. The Lower Himalayas from Kashmir to Eastern Assam, Burma and, according to Blyth, the Malay Peninsula. It is extremely common in parts of Assam and almost equally so in Eastern Bengal throughout the plains. It also extends into the plains of Northern India but is much less common than further East and its exact limits to the South have not been denned.

Nidification. The Northern race of Long-billed Vulture breeds from the middle of November to the end of February and builds its nest on trees, not on cliffs, even when these are available. The nest is like that of the other Vultures which breed in similar places, great structures of sticks and branches, used for several years but always renewed and lined with green branches and leaves. Parker found them breeding in colonies in the 24th Parganas and I found large colonies in Assam and Eastern Bengal, though in no case did I find more than one nest in any tree. Some were built low down, some at inaccessible heights in huge Cotton-trees. Only one egg is laid, like that of other birds of the genus but, as a series, better marked and I have one or two which are more like well-marked Eagle's eggs than those of Vultures. One hundred eggs average 84.7 X 63.6 mm.: maxima 91.8 X 65.4 and 90.7 X 67.9 mm.; minima 76.1 x 62.8 and 78.4 x 59.9 mm.

Habits. Those of the genus. It is one of the Vultures which haunt the vicinity of villages and breed on the trees round about them.
