British Birds in Their Haunts

by C. A. Johns

SLAVONIAN GREBE
PÓDICIPES AURITUS

Bill strong, shorter than the head, compressed throughout its whole length, black, with the tip red; eyes with a double iris, the inner yellow, the outer red; distance from the nostrils to the tip of the bill six or seven lines; head and bushy ruff glossy black; two horn-like crests orange-red; lore, neck, and breast, bright chestnut; upper plumage dusky; secondaries and under parts white; bill black, rose-coloured at the base and red at the tip. Young—crest and ruff wanting; upper plumage and flanks dusky ash, under parts white; irides white, surrounded by red. Eggs dirty white.

The Slavonian, or Horned Grebe, approaches so closely in habits to the two preceding species that it is unnecessary to say more than that it inhabits the northern parts of America and Europe, visiting us from autumn to spring. Audubon describes its nest as a rude structure of weeds, situated at a distance of about twelve feet from the water's edge; but other authors state that though it constructs its nest of these materials, it disposes it among weeds in such a way that it rises and falls with every alteration in the level of the water. It lays from five to seven eggs, and the male is supposed to assist in the office of incubation.

THE BLACK-NECKED OR EARED GREBE
PÓDICIPES NIGRICOLLIS

In summer the head and neck of this species are black, with a triangular patch of long golden-reddish feathers on the ear-coverts. Breast and belly white—flanks a dull chestnut, bill black, upcurved slightly. In winter it resembles the last named Grebe in plumage, excepting that it is white on the primaries. Length twelve inches.

This is essentially a bird of the south, visiting us in spring and summer, but also now and again in autumn and winter, but this more rarely. It is said to have bred occasionally in the southern counties, and more often in Suffolk and Norfolk. To the north it becomes more scarce, although it has been observed up to the Orkneys. Just a few instances are recorded from Cumberland, but the bird is rare on our western side. Very few have been met with in Ireland. In Algeria it is said to nest in "societies more densely crowded than any rookery," the nests being raised on islets with stout foundations constructed by the bird. In Denmark the nests observed were on tussocks at the edge of the lake, and they were made of moss, part of which the female used to cover her eggs with on leaving them.

THE LITTLE GREBE, OR DABCHICK
PÓDICIPES FLUVIÁTILIS

Bill very short, shining, compressed; no crest or ruff; distance from nostrils to tip of the bill five lines; tarsus with a double row of serratures behind; head black; cheeks bright chestnut; breast and flanks dusky, mottled with white; upper parts dark brown, tinged with green; primaries ash-brown; secondaries white at the base and on the inner web, under parts dusky ash, tinged on the thighs with reddish; bill black, whitish at the tip and base of the lower mandible; irides reddish brown; feet externally greenish brown, beneath flesh-colour. Young birds are ash-brown above, slightly tinged with red; breast and flanks reddish white; belly pure white; bill brown and yellowish ash. Length nearly ten inches. Eggs dirty white.

The Lesser Grebe, or, as it is more commonly called, the Dabchick, is the only species with which it is possible to become familiarly acquainted in Britain. It frequents rivers, ponds, and lakes, in all parts of the country, rarely flying, and still more rarely coming to land.

Rambling by the side of a sluggish river, the sides of which are lined with reeds or bulrushes, one may often descry, paddling about with undecided motion, what appears to be a miniature Duck no longer than a Blackbird. It does not, like the Moor-hen, swim with a jerking movement, nor when alarmed does it half swim and half fly in a direct line for the nearest bank of weeds. If you are unobserved, it swims steadily for a short distance, then suddenly disappears, making no splash or noise, but slipping into the water as if its body were lubricated. It is diving for its food, which consists of water insects, molluscs, small fish and worms. As suddenly as it dives so suddenly does it reappear, most likely not far from the spot where you first observed it:
