Grebes are small to medium-large in size ranging from the least grebe (Tachybaptus dominicus), at 120 g (4.2 oz) and 23.5 cm (9.3 in), to the great grebe (Podiceps major), at 1.7 kg (3.7 lb) and 71 cm (28 in). Despite these size differences grebes are a homogenous family of waterbirds with very few or slight differences among the genera.
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 ...
The pied-billed grebe breeds in south-central Canada, throughout the United States, Central America, the Caribbean, and temperate South America. [10] These grebes may lay up to two sets of eggs a year. [13] Their nests sit on top of the water, their eggs sitting in vegetation that resides in the water. [17]
The great crested grebe (Podiceps cristatus) is a member of the grebe family of water birds. The bird is characterised by its distinctive appearance, featuring striking black, orange-brown, and white plumage, and elaborate courtship display that involves synchronised dances and displays.
The calls of Clark's grebe are similar to its western counterpart, however, during courtship the birds make an 'advertising call' to attract mates -this sounds like a single, extended kreeeed as opposed to the two-note kreed-kreet of the western grebe. [4] The calls of the grebe tend to vary very little between sexes.
The red-necked grebe was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux. [2] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text.

The shared history of birds and dinosaurs is well-established, but exactly how true birds evolved during the Mesozoic is a bit of a mystery. Adding to this conundrum are fossilized footprints of ...
The name "eared grebe" is nearly a century older than the name "black-necked grebe". The latter was first used in 1912 by Ernst Hartert, in an effort to bring the common name of the species in line with its scientific name, [ 14 ] and/or to avoid the long history of confusion between the vernacular name "eared" with the scientific name of the ...
