"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."

Major C.T. Bingham writes:—

"This Crow, so common at Allahabad, is very scarce here at Delhi. In fact I have only seen one pair.

"At Allahabad it lays in February and March. I have, however, only found one nest, a rather loose structure of twigs and a few thick branches with rather a deep depression in the centre. It was placed on the very crown of a high toddy palm (Borassus flabelliformis) and was unlined save for a wad of human hair, on which the eggs, two in number, lay; these I found hard-set (on the 13th March); in colour they were a pale greenish blue, boldly blotched, spotted, and speckled with brown."

Colonel Butler has furnished me with the following note on the breeding of the Jungle-Crow:—

"Belgaum, 12th March, 1880.—A nest containing four fresh eggs. It consisted of a loose structure of sticks lined with hair and leaves, and was placed at the top of and in the centre of a green-foliaged tree in a well-concealed situation about 30 feet from the ground. 18th March: Two nests, each containing three slightly incubated eggs; one of the nests was quite low down in the centre of an 'arbor vitae' about 12 feet from the ground. 31st March: Another nest containing four slightly incubated eggs. Some of the latter nests were very solidly built, and not so well Concealed. 11th April: Two more nests, containing five incubated and three slightly incubated eggs respectively; and on the 14th April a nest containing four slightly incubated eggs. These birds, when the eggs are at all incubated, often sit very close, especially if the nest is in an open situation, and in many instances I have thrown several stones at the nest, and made as much row as I could below without driving the old bird off, and I have seen my nest-seeker within a few yards of the nest after climbing the tree before the old bird flew off. On the 26th of April I found two more nests, one containing four young birds just hatched, the other three fresh eggs. On the 27th another nest containing three fresh eggs, and on the 28th a nest of three fresh eggs. On the 5th May two more nests containing four fresh and four incubated eggs respectively."

"In the Nilghiris," writes Mr. Davison, "the Corby builds a coarse nest of twigs, lined with cocoanut-fibre or dry grass high up in some densely-foliaged tree. The eggs are usually four, often five, in number. The birds lay in April and May."

Miss Cockburn again says:—"They build like all Crows on large trees merely by laying a few sticks together on some strong branch, generally very high up in the tree. I do not remember ever seeing more than one nest on a tree at a time, so that they differ very much from the Rook in that respect. They lay four eggs of a bluish green, with dusky blotches and spots, and nothing can exceed the care and attention they bestow on their young. Even when the latter are able to leave their nests and take long flights, the parent birds will accompany them as if to prevent their getting into mischief. The nests are found in April and May."

Mr. J. Darling, jun., writes from the Nilghiris:—"I have found the nest of this Crow pretty nearly all over the Nilghiris. The usual number of eggs laid is four, but on one occasion, near the Quinine Laboratory in the Government Gardens at Ooty, I procured six from one nest. The breeding-season is from March to May, but I have taken eggs as early as the 12th February."

From Ceylon, we hear from Mr. Layard that "about the villages the Carrion-Crow builds its nest in the cocoanut-trees. In the jungles it selects a tall tree, amid the upper branches of which it fixes a framework of sticks, and on this constructs a nest of twigs and grasses. The eggs, from three to five, are usually of a dull greenish-brown colour, thickly mottled with brown, these markings being most prevalent at the small end. They are usually laid in January and February."

Mr. J.E. Cripps informs us that in Eastern Bengal it is "common and a permanent resident. Occasionally found in the clumps of jungle that are found about the country, which the next species never affects. Breeds in the cold weather. I had noticed a pair building on a Casuarina tree in my garden, about 50 feet off the ground, and on the 18th December, 1877, I took two perfectly fresh eggs from it; and again on the 9th January, 1878, I found two callow young in this same nest, the birds never having deserted it. The lining used for this nest was principally jute-fibre—any tree is selected to build on; the nests are placed from 15 to 50 feet off the ground. Some nests are very well concealed, whereas others are quite exposed. On the 15th January I found a nest about 15 feet up a small kudum tree, standing in a large plain, and which had a lining of hair from the tail-tufts of cows. There was one fresh egg, and a week later I got another fresh egg from this very nest. From two to four eggs are in each nest."

Mr. Oates writes from Pegu:—"These birds all begin to build about the same time, and I have taken numerous nests at the end of January. At the end of February most nests contain young birds."

Mr. W. Theobald gives the following notes on the nidification of this bird in Tenasserim and near Deoghur:—

"Lays in the third week of February and fourth week of March: eggs ovato-pyriform; size 1·66 by 1·15; colour, dull sap-green much blotched with brown; nest carefully placed in tall trees."

The eggs, though smaller, closely resemble, as might have been expected, those of the Raven, but they are, I think, typically somewhat broader and shorter. Almost every variety, as far as coloration goes, to be found amongst those of the Raven, are found amongst the eggs of the present species, and vice versâ; and for a description of these it is only necessary to refer to the account of the former species; but I may notice that amongst the eggs of C. macrorhynchus I have not yet noticed any so boldly blotched as is occasionally the case with some of the eggs of the Raven, which remind one not a little, so far as the character of the markings go, of eggs of Oedicnemus crepitans and Esacus recurvirostris. Like those of the Raven the eggs exhibit little gloss, though here and there a fairly glossy egg is met with. Eggs from various parts of the Himalayas, of the plains of Upper India, of the hills and plains of Southern India, do not differ in any respect. Inter se the eggs from each locality differ surprisingly in size, in tone of colour, and in character of markings; but when you compare a dozen or twenty from each locality, you find that these differences are purely individual and in no degree referable to locality.

There are just as big eggs and just as small ones from Simla and
