4. Corvus macrorhynchus, Wagler. _The Jungle-Crow_.

Corvus culminatus, _Sykes, Jerd. B, Ind._ ii, p. 295,

Corvus levaillantii; _Less., Hume, Rough Draft N. & E._ no. 660.

The Jungle-Crow (under which head I include[A] _C. culminatus,_

Sykes, _C. intermedius_, Adams, _C. andamanensis_, Tytler, and each

and all of the races that occur within our limits) breeds almost

everywhere in India, alike in the low country and in the hills both of

Southern and Northern India, to an elevation of fully 8000 feet.

to Yarkand,' p. 85.]

March to May is, I consider, the normal breeding-season; in the plains

the majority lay in April, rarely later, and in the hills in May; but

in the plains a few birds lay also in February.

The nest is placed as a rule on good-sized trees and pretty near their

summits. In the plains mangos and tamarinds seem to be preferred, but

I have found the nests on many different kinds of trees. The nest is

large, circular, and composed of moderate-sized twigs; sometimes it is

thick, massive, and compact; sometimes loose and straggling; always

with a considerable depression in the centre, which is smoothly lined

with large quantities of horsehair, or other stiff hair, grass,

grass-roots, cocoanut-fibre, &c. In the hills they use _any_ animal's

hair or fur, if the latter is pretty stiff. They do not, according to

my experience, affect luxuries in the way of soft down; it is always

something moderately stiff, of the coir or horsehair type; nothing

soft and fluffy. Coarse human hair, such as some of our native

fellow-subjects can boast of, is often taken, when it can be got, in

lieu of horsehair.

They lay four or five eggs. I have quite as often found the latter as

the former number. I have never myself seen six eggs in one nest, but

I have heard, on good authority, of six eggs being found.

Captain Unwin writes: "I found a nest of the Bow-billed Corby in the

Agrore Valley, containing four eggs, on the 30th April. It was placed

in a Cheer tree about 40 feet from the ground, and was made of sticks

and lined with dry grass and hair."

Mr. W. Theobald makes the following remarks on the breeding of this

bird in the Valley of Cashmere:--

"Lays in the third week of April. Eggs four in number, ovato-pyriform,

measuring from 1·6 to 1·7 in length and from 1·2 to 1·25 in breadth.

Colour green spotted with brown; valley generally. Nest placed in

Chinar and difficult trees."

Captain Hutton tells us that the Corby "occurs at Mussoorie throughout

the year, and is very destructive to young fowls and pigeons; it

breeds in May and June, and selects a tall tree, near a house or

village, on which to build its nest, which is composed externally of

dried sticks and twigs, and lined with grass and hair, which latter

material it will pick from the backs of horses and cows, or from

skins of animals laid out to dry. I have had skins of the Surrow

(_Noemorhaedus thar_) nearly destroyed by their depredations. The eggs

are three or four in number."

From the plains I have very few notes. I transcribe a few of my own.

"On the 11th March, near Oreyah, I found a nest of a Corby--good large

stick nest, built with tamarind twigs, and placed fully 40 feet from

the ground in the fork of a mango-tree standing by itself. The nest

measured quite 18 inches in diameter and five in thickness. It was a

nearly flat platform with a central depression 8 inches in diameter,

and not more than 2 deep, but there was a solid pad of horsehair more

than an inch thick below this. I took the mass out; it must have

weighed half a pound. Four eggs much incubated.

"_Etawah, 14th March_.--Another nest at the top of one of the huge

tamarind-trees behind the Asthul: could not get up to it. A boy

brought the nest down; it was not above a foot across, and perhaps 3

inches deep; cavity about 6 inches in diameter, thickly lined with

grass-roots, inside which again was a coating of horsehair perhaps a

rupee in thickness; nest swarming with vermin. Eggs five, quite fresh;

four eggs normal; one quite round, a pure pale slightly greenish

blue, with only a few very minute spots and specks of brown having a

tendency to form a feeble zone round the large end. Measures only 1·25

by 1·2. Neither in shape, size, nor colour is it like a Corby's egg;

but it is not a Koel's, or that of any of our parasitic Cuckoos, and

I have seen at home similar pale eggs of the Rook, Hooded Crow,

Carrion-Crow, and Raven.

"_Bareilly, May 10th_.--Three fresh eggs in large nest on a

mango-tree. Nest as usual, but lined with an immense quantity of

horsehair. We brought this home and weighed it; it weighed six ounces,

and horsehair is very light."
