Corvus monedula, Linn., Hume, Rough Draft N. & E. no. 665.
I only know positively of Jackdaws breeding in one district within our limits, viz. Cashmere ; but I have seen it in the bills in summer, as far east as the Valley of the Beas, and it must breed everywhere in suitable localities between the two.
In the cold season of course the Jackdaw descends into the plains of the North-west Punjaub, is very numerous near the foot of the hills, and has been found in cis-Indus as far east as Umballa, and south at Ferozpoor, Jhelum, and Kalabagh. In Trans-Indus it extends unto the Dehra Ghazi Khan. district.
I have never taken its eggs myself.
Mr. W. Theobald makes the following remarks on its nidifica¬tion in the Valley of Cashmere :—
“Lays in the first week of May ; eggs four, five, and six in number, ovato-pyriform and long ovato-pyriform. measuring from 1.26. 1.45, to 1.60 in length, and from 0.9 to 1.00 in breadth ; colour pale, clear bluish green, dotted and spotted with brownish black ; valley generally ; in holes of rocks, beneath roofs, and in tall trees.”
Dr. Jerdon says :—“It builds in Cashmere in old ruined palaces, holes in rocks, beneath roofs of houses, and also in tall trees, laying four to six eggs, pale bluish green, dotted and spotted with brownish black."
Mr. Brookes writes :—"The Jackdaw breeds in Cashmere in all suitable places : holes in old Chinar (Plane) trees, and in house walls, under the eaves of houses, &c. I did not note the materials of the nests, but these will be the same as in England."
The eggs of this species are typically rather elongated ovals, somewhat compressed towards one end. The shell is fine, but has only a faint gloss. The ground-colour is a pale greenish white, but in some eggs there is very little green, while in a very few the ground is quite a bright green. The markings, sometimes very fine and close, sometimes rather bold and thinly set, consist of specks or spots of deep blackish brown, olive-brown, and pale inky purple. In most eggs all these colours are represented, but in some eggs the olive, in others the blackish brown is almost entirely wanting. In some eggs the markings are very dense towards the large end, in others they are pretty uniformly dis¬tributed over the whole surface ; in some they are very minute and speckly, in others they average the tenth of an inch in diameter.
The eggs that I possess vary from 1.34 to 1.52 in length, and from 0.93 to 1.02 in breadth ; but the average of sixteen eggs was 1.4 by 0.98.
