Tur Otogyps calvus is a truly Indian species, for it inhabits every part of that great peninsula; but it is
not so gregarious, nor found in such great numbers, as the other members of the genus.

Dr. Adams states that “It is found in Bengal, the Deccan, and Lower Himalayan Range, but does
not travel any distance into the interior of the mountains. This species is easily distinguished from the
other Vultures by the red colour of the skin and neck. In size it is less than Gyps Bengalensis, the total
length being about 23 feet.”

But by far the most valuable account of this species is that given by Captain Burgess, in the ‘ Proceedings
of the Zoological Society of London’ for 1854, where he says :—

‘This Vulture, as far as I had opportunities of observing it, is much more common in the Deccan than
either the large (Vadtur indicus) or the small brown Vulture (Vudtur Bengalensis). JY have never, however,
seen more than two or three together, and these generally in the low ranges of hills which intersect that
part of the country. As this bird has doubtless been already figured, it is not my purpose in these notes
to enter into any description of it, but merely to state what I have observed of its habits, food, manner and
time of nesting, with any other information regarding it which I may have gained by actual investigation,
or learned from credible sources. In its habits this Vulture, I should certainly say, is not gregarious : I do
not remember to have seen more than four or five together; and then it has been for the purpose of
partaking of a social meal. It flies in circles, with the wings extended, apparently without motion, and
with their tips pointed upwards, the legs being stretched out beneath the tail. The food consists of
decaying animal substances: one which I shot drinking in a stream disgorged the entire leo Of a cat.
It breeds during the months of February and March. In my notes taken at the time I find the following :
—‘ March 7.—Found to-day, on the top of a rather low Peepul (a species of Banian tree), the nest of a
Black Vulture, on which one of the old birds was sitting. The nest, which was very large, was built of
small sticks ; it contained one egg. On the same tree, a pair of the Black-headed Ibis (Zuntalus melano-
cephalus) had also built their nest... ... . March 19.—Shot a male Black Vulture sitting on one egg;
the nest was about a yard in circumference, built on the top of a thorny tree; it was composed of the
thorny branches, and other sticks below it. Among the thorny twigs forming the nest were two small
nests, belonging to birds of the Passerine order, containing young.’ In both these cases only one ege was
found, of a pure white colour, 35% inches in length by 325 inches in width. In a third also only one egg
was found. The natives say the bird lays two eggs, containing a male and a female bird ; but these facts
seem opposed to such a statement.” :

I am indebted to J. H. Gurney, Esq., for permission to copy the drawing of this species of Vulture, made
for him by Mr. Wolf from a fine living example.

Base of the bill, face, and wattles naked and of a dull red; ruff at the base of the neck white; downy
feather on the fore part of the neck pale brown; the remainder of the plumage black, with a wash of grey
on the shoulders and the outer webs of the primaries ; legs and feet deep pinkish red; nails black.

The figure, which represents a fully adult male, is about one-third of the natural size.
