The Nests and Eggs of Indian Birds, Volume 1 | Page 4

species I cannot say. Of course they never breed in company: I never found two of their nests within 100 yards of each other, and, as a rule, they will not be found within a quarter of a mile of each other.
Five is, I think, the regular complement of eggs; very often I have only found four fully incubated eggs, and on two or three occasions six have, I know, been taken in one nest, though I never myself met with so many.
I find the following old note of the first nest of this species that I ever took:--
"At Hansie, in Skinner's Beerh, December 19, 1867, we found our first Raven's nest. It was in a solitary Keekur tree, which originally of no great size had had all but two upright branches lopped away. Between these two branches was a large compact stick nest fully 10 inches deep and 18 inches in diameter, and not more than 20 feet from the ground. It contained five slightly incubated eggs, which the old birds evinced the greatest objection to part with, not only flying at the head of the man who removed them, but some little time after they had been removed similarly attacking the man who ascended the tree to look at the nest. After the eggs were gone, they sat themselves on a small branch above the nest side by side, croaking most ominously, and shaking their heads at each other in the most amusing manner, every now and then alternately descending to the nest and scrutinizing every portion of the cavity with their heads on one side as if to make sure that the eggs were really gone."
Mr. W. Theobald makes the following note of this bird's nidification in the neighbourhood of Pind Dadan Khan and Katas in the Salt Range:--
"Lay in January and February; eggs, four only; shape, ovato-pyriform; size, 1·7 by 1·3; colour, dirty sap green, blotched with blackish brown; also pale green spotted with greenish brown and neutral; nest of sticks difficult to get at, placed in well-selected trees or holes in cliffs."
I have not verified the fact of their breeding in holes in cliffs, but it is very possible that they do. All I found near Pind Dadan Khan and in the Salt Range were doubtless in trees, but I explored a very limited portion of these hills.
Colonel C.H.T. Marshall, writing from Bhawulpoor on the 17th February, says: "I succeeded yesterday in getting four eggs of the Punjab Raven. The eggs were hard-set and very difficult to clean."
From Sambhur Mr. R.M. Adam tells us:--"This Raven is pretty common during the cold weather, but pairs are seen about here throughout the year. They are very fond of attaching themselves to the camps of the numerous parties of Banjaras who visit the lake.
"I obtained a nest at the end of January which contained three eggs, and a fourth was found in the parent bird. The nest was about 15 feet from the ground in a Kaggera tree (_Acacia leucophloea_) which stood on a bare sandy waste with no other tree within half a mile in any direction."
The eggs of the Punjab bird are, as might be expected, much the same as those of the European Raven. In shape they are moderately broad ovals, a good deal pointed towards the small end, but, as in the Oriole, greatly elongated varieties are very common, and short globular ones almost unknown. The texture of the egg is close and hard, but they usually exhibit little or no gloss. In the colour of the ground, as well as in the colour, extent, and character of the markings, the eggs vary surprisingly. The ground-colour is in some a clear pale greenish blue; in others pale blue; in others a dingy olive; and in others again a pale stone-colour. The markings are blackish brown, sepia and olive-brown, and rather pale inky purple. Some have the markings small, sharply defined, and thinly sprinkled: others are extensively blotched and streakily clouded; others are freckled or smeared over the entire surface, so as to leave but little, if any, of the ground-colour visible. Often several styles of marking and shades of colouring are combined in the same egg. Almost each nest of eggs exhibits some peculiarity, and varieties are endless. With sixty or seventy eggs before one, it is easy to pick out in almost every case all the eggs that belong to the same nest, and this is a peculiarity that I have observed in the eggs of many members of this family. All the eggs out of the same nest usually closely resemble each other, while almost any two eggs out of different nests are markedly dissimilar.
They vary from 1·72 to 2·25 in length, and from 1·2 to 1·37 in width; but the average
