THE PIED WAGTAIL.
The nest of this bird is situated in holes in stone walls, bridges, crevices of rocks, quarries, &c. I remember on one occasion finding one in the stump of a rotten tree which had broken off about eleven feet from the ground; they are also found in pollard willows. The nest is chiefly composed of moss, small fine grass, fibrous roots, wool, horse and cow-hair. The eggs number from four to six, and are of a grey colour, speckled with light umber-brown.
THE HERON.
The Heron lays four or five eggs of a pale blue, with a tinge of green. Her nest is composed of a very liberal collection of sticks, and is lined in the interior with wool, and occasionally rags. It is situated on the tops of high trees. Like the Rooks, Herons build in societies, which are called heronries.
THE WOODCOCK.
The Woodcock lays four eggs of a yellow-white colour, blotched with pale chestnut-brown. Her nest is generally found amongst the underwood at the foot of a tree, where she does not appear to try to avoid its being seen, but scratches a slight hollow, lining it with dead leaves and the withered fronds of the bracken. Although the great bulk of these birds are migrants, it is now proved beyond doubt that many are bred yearly in this country. Like the Partridge, Grouse, &c., the young leave the nest as soon as hatched, and are most carefully looked after by the parent bird.
