5. Corvus frugilegus.

The Rook.

Corvus frugilegus, Linn. Syst. Nat. i, p. 156 (1766); Blyth, Cat. p. 90; Horsf. & M. Cat. ii, p. 557; Jerd. B. I. ii, p. 302; Hume, Cat. no. 664; Biddulph, Ibis, 1881, p. 77, 1882, p. 281; Scully, Ibis, 1881, p. 571; Hume, S. F. x, p. 518. Trypanocorax frugilegus (Linn.), Sharpe, Cat. B. M. iii, p. 9.

Coloration. The whole plumage black; the head, neck, and lower plumage richly glossed with purplish blue, the upper plumage with violet-purple.

Bill and feet black; iris blackish brown (Hume Coll.).

Length about 19; tail 6.5 to 8 ; wing 12 to 13; tarsus about 2.2 ; bill from gape 2.5 to 2.8.

The nestling is without any gloss at first but quickly assumes it. About January, or when the young bird is about nine months old, the naral bristles are cast, and by March the front part of the head has become entirely denuded of feathers.

Distribution. The Rook occurs in Kashmir, the Hazara country and the extreme north-west portion of the Punjab in the winter The Hume Collection contains birds killed at Abbottabad from October to February, and Scully states that this species is common in Gilgit from the third week in October to the third week in April.

The Rook is found in Central Asia and in Europe, but to the east it is replaced by C. pastinator, which has a smaller extent of the face denuded of feathers.

Habits, &c. The Book frequents the better cultivated parts of the country in large flocks, feeding in meadows and ploughed land on worms, snails and grubs. It does not breed in India. In Europe it breeds in large societies, building a nest similar to the Crow's on large trees.
