This pretty little bird makes no nest in the proper sense of the word, although I have found a few pebbles and small shells used when a rocky place instead of a sandy beach has been chosen for breeding upon. Its nest is generally well above high-water-mark, amongst fine sand, shingle, or on bare rock round our coast, and on the shores of inland sheets of water. The eggs number four, and vary from pale buff to stone or cream colour, spotted and speckled all over with small brownish-black and underlying inky-grey marks. THE MANX SHEARWATER. The Manx Shearwater breeds on the western coasts of England and Scotland, in the Hebrides and islands to the north of Scotland; also in several parts of the Irish coast and the off-lying islands. Its nest is situated at the end of a deep burrow, which is generally dug by the bird itself. Some observers have reported it to consist of bits of grass and stalks, and others have found no attempt at all at nest-building in some of the burrows they have opened. It lays a single white, smooth egg. THE PINTAIL DUCK. This uncommon Duck breeds in one or two parts of Ireland and Scotland still, it is said on good authority. Its nest consists of rushes, sedge, dead grass, and tufts of dark brown down bearing white tips, and is placed amongst rushes and such other coarse vegetation as will afford the bird shelter. The eggs number from six to eight, or even ten, of a pale buff colour tinged with green. LEACH'S FORK-TAILED PETREL. The St. Kilda group of islands forms the principal British-breeding haunt of this bird, although colonies nest in the Hebrides and on the Blaskets off the Irish coast. The nest is situated at the end of a burrow made by the bird itself, or under rocks, and is composed of withered grass, moss, and lichens. Only one egg is laid, white in ground colour, with a belt of small brownish-red spots round the larger end. THE RED-NECKED PHALAROPE. A little withered grass or other herbage is used to line the depression selected by this bird for its nesting-place, which is situated on the ground in grassy swamps and marshes, near water as a rule, in the North of Scotland and some of the islands lying to the west and north thereof. Four eggs are laid, varying in ground colour from olive to pale buff, spotted, speckled, and blotched with varying shades of dark brown and underlying specks of light grey. THE HOOPOE. Although this bird has bred in different parts of England, its chances of doing so now are somewhat remote, on account of the merciless persecution it suffers at the hands of gunners. Its nest is situated in holes in trees, walls, or rocks, and is composed of bits of straws and dry grass. The eggs number from five to seven, and vary from light greenish-blue to pale buff, with minute pit marks over their surface. [Illustration: EGGS.
