Order PASSERES. Family CORVIDAE. Subfamily CORVINAE.
1. Corvus corax, Linn. The Raven.
Corvus corax, Linn., Jerd. B. Ind. ii, p. 293. Corvus lawrencii, Hume; Hume, Rough Draft N. &E. no. 657.I separated the Punjab Raven under the name of Corvus lawrencei ('Lahore to Yarkand,' p. 83), and I then stated, what I wish now to repeat, that if we are prepared to consider C. corax, C. littoralis, C. thibetanus, and C. japonensis all as one and the same species, then C. lawrencei too must be suppressed; but if any of these are retained as distinct, then so must C. lawrencei be[A].
[Footnote A: I think it impossible to separate the Punjab Raven from the Ravens of Europe and other parts of the world, and I have therefore merged it into C. corax.—ED.]
The Punjab Raven breeds throughout the Punjab (except perhaps in the Dehra Ghazee Khan District), in Bhawulpoor, Bikaneer, and the northern portions of Jeypoor and Jodhpoor, extending rarely as far south as Sambhur.
To Sindh it is merely a seasonal visitant, and I could not learn that they breed there, nor have I ever known of one breeding anywhere east of the Jumna. Even in the Delhi Division of the Punjab they breed sparingly, and one must go further north and west to find many nests.
The breeding-season lasts from early in December to quite the end of March; but this varies a little according to season and locality, though the majority of birds always, I think, lay in January.
The nest is generally placed in single trees of no great size, standing in fields or open jungle. The thorny Acacias are often selected, but I have seen them on Sisoo and other trees.
The nest, placed in a stout fork as a rule, is a large, strong, compact, stick structure, very like a Rook's nest at home, and like these is used year after year, whether by the same birds or others of the same 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.
