Little grebe

The little grebe was formally described in a sales catalogue by the German naturalist Peter Simon Pallas in 1764 under the binomial name Colymbus ruficollis.^[3][4] The type locality is the Netherlands.^[5] The specific epithet is Modern Latin meaning "red-necked", from Latin rufus meaning "red", "ruddy" or "rufous" and Modern Latin -collis meaning "-necked".^[6] The little grebe is now one of five species placed in the genus Tachybaptus that was introduced in 1789 by German naturalist Johann Friedrich Gmelin.

Subspecies

Ten subspecies are currently accepted, four widespread, and six with restricted ranges; they are separated principally by size, eye colour, which varies from dark to light from west to east, to red in the southeast, and extent of white on the secondary feathers of the wing, which varies from none in temperate northern regions, to extensive white in tropical regions.^[7][8][9]

Close

The last three subspecies in the above table, T. r. vulcanorum, T. r. tricolor and T. r. collaris, have sometimes been treated as a separate species, the tricoloured grebe;^[10] it differs only slightly, notably in the red eyes, and blackish flanks and underparts.^[11]

The little grebe is a small water bird with a pointed bill. The adult is unmistakable in summer, predominantly dark above with its rich, rufous colour neck, cheeks and flanks, and bright yellow gape. The rufous is replaced by a dirty brownish grey in non-breeding and juvenile birds.

Juvenile birds have a yellow bill with a small black tip, and black and white streaks on the cheeks and sides of the neck as seen below. This yellow bill darkens as the juveniles age, eventually turning black in adulthood.

In winter, its size, buff plumage, with a darker back and cap, and "powder puff" rear end enable easy identification of this species. The little grebe's breeding call, given singly or in duet, is a trilled repeated weet-weet-weet or wee-wee-wee which sounds like a horse whinnying.

This bird breeds in small colonies in heavily vegetated areas of freshwater lakes across Europe, much of Asia down to New Guinea, and most of Africa. Most birds move to more open or coastal waters in winter, but it is only migratory in those parts of its range where the waters freeze. Outside of breeding season, it moves into more open water, occasionally even appearing on the coast in small bays.^[1]

The little grebe is an excellent swimmer and diver and pursues its fish and aquatic invertebrate prey underwater. It uses the vegetation skilfully as a hiding place.

Like all grebes, it nests at the water's edge, since its legs are set very far back and it cannot walk well. Usually four to seven eggs are laid. When the adult bird leaves the nest it usually takes care to cover the eggs with weeds. This makes it less likely to be detected by predators.^[12] The young leave the nest and can swim soon after hatching, and chicks are often carried on the backs of the swimming adults.^[13] In India, the species breeds during the rainy season.^[14]
