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.
Grebes are small to medium-large freshwater diving birds. They have lobed toes and are excellent swimmers and divers. However, they have their feet placed far back on the body, making them quite ungainly on land. Five species of grebe have been recorded in Georgia. Pied-billed grebe, Podilymbus podiceps; Horned grebe, Podiceps auritus

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.
