This bird makes a slight nest of bents and leaves upon the ground in grass, corn, or clover fields; however, instances have been cited where it has been found at considerable elevation. But this departure from the general rule I have noticed with other birds on rare occasions. Her eggs number from twelve to eighteen, of a yellow-grey or cream colour, marked with red or cinnamon-brown. THE SANDERLING. The Sanderling is only a visitor to our shores, and breeds in Arctic countries, such as Labrador, Greenland, &c. Its nest is composed of grass and built upon the ground. The eggs are four in number, of a buffish-olive ground colour, spotted and mottled plentifully with dark brown or black, also with indistinct sub-markings of a greyish tinge. THE LONG-TAILED TIT. Hedges and bushes are the positions taken up by this skilled little architect and builder, whose beautiful work wins the admiration of all naturalists. Oval in shape, it is of large size compared with the bird, and strongly and compactly put together with wool, lichens, and moss, the two former of which adhere very closely when they once become entangled. A small hole is left on one side, pretty high up, for ingress and egress, and the inside is lined with feathers, which make it as warm and comfortable, at least to the human understanding, as the outside is compact. The eggs number from seven to ten, and even sixteen or twenty, which are probably the production of more than one bird; white or rosy-white until blown (by reason of the yolk showing through the thin transparent shell), with very small reddish-brown spots round the larger end. THE RAZOR-BILL. The Guillemot and Razor-Bill appear to be very much alike in the choice of their position for breeding purposes, and alike only lay one egg each; but that of the latter differs very much from the former in diversity of colouring. It is white or buffy-white, spotted and blotched with black, chestnut, or reddish-brown. THE SANDWICH TERN. Low, sandy islands, such as the Wamses at the Farne and Scilly Isles, and at suitable places on the Scottish and Irish coasts, are the favourite breeding places of this Tern. Sometimes a slight hollow is scratched in the sand or gravel; at others no declivity at all is formed for the nest. Occasionally a few bits of grass are used as a lining. The eggs number two or three, and vary from creamy-white to dark buff in ground colour. They are blotched and spotted with reddish- and blackish-brown and underlying light grey markings. THE ARCTIC TERN. Breeds on low islands and in suitable places along the coast, chiefly in the northern parts of our kingdom. I have found most nests amongst the shingle. As a rule, no materials whatever are used. The eggs are two or three, varying from greyish-buff to buffish-brown (I have seen them occasionally pale blue), spotted and blotched with blackish-brown and underlying pale grey. The eggs of this bird run slightly smaller than those of the Common Tern.
