Although in sadly diminished numbers, the great crested grebe still breeds regularly in many localities in England, especially in the eastern counties, and in a few situations in Wales and Ireland. In the northern counties of England it is very rare, and does not breed in Scotland: it is there a winter migrant from the north of Europe. The habits of the grebe when on the water are similar to those of the diver. It is adapted to a swimming and diving existence; feeds on fish, frogs, water-beetles, and other small aquatic creatures; when alarmed it sinks its body deeper and deeper into the water, and when pursued, or in danger, seeks to escape by diving. It makes little use of its wings, except when migrating. At most times it is a silent bird, but in the breeding season utters a harsh, grating cry. The grebe makes a large platform nest of aquatic plants, placed on the water among the reeds. Four eggs are laid, the shell pale blue in colour, but covered with a soft, white, chalky substance. Invariably, when leaving the nest the bird covers the eggs with moss and weeds, and the usual inference is that this is done to hide them from rapacious egg-eating birds; but Seebohm is of the opinion that the eggs are covered to be kept warm, and he says that they are covered only after the full complement is laid and incubation begun. Little Grebe, or Dabchick. Tachybaptes fluviatilis. [Illustration: FIG. 117.--LITTLE GREBE. ⅙ natural size.] Head, neck, and upper parts dark brown; a little white on the secondaries; chin black; cheeks, throat, and sides of the neck reddish chestnut; under parts greyish white; flanks dusky brown; bill horn-colour; legs and feet dull green. Length, nine inches and a half. * * * * * The little grebe, or dabchick, is less than the teal in size, and differs from the great crested grebe in about the same degree as the partridge does from the pheasant. It is the one common and well-known species of grebe in this country, being resident in suitable localities in all parts of the United Kingdom. In summer it is generally diffused, and is to be met with even on small pools and streams; in winter it shifts its ground, resorting to the rivers and larger bodies of water, and in very severe weather to the sea-coast.
