The Eurasian coot is 36–38 cm (14–15 in) in length with a wing-span of 70–80 cm (28–31 in); males weigh around 890 g (31 oz) and females 750 g (26 oz). It is largely black except for the white bill and frontal shield (which gives rise to the phrase "as bald as a coot", in use as early as 1430). As a swimming species, the coot has partial webbing on its long strong toes. The sexes are similar in appearance.
The juvenile is paler than the adult, has a whitish breast, and lacks the facial shield; the adult black plumage develops when about 3–4 months old, but the white shield is only fully developed at about one year old.
The Eurasian coot is a noisy bird with a wide repertoire of crackling, explosive, or trumpeting calls, often given at night.
The coot breeds across much of the Old World on freshwater lakes and ponds, and like its relative the common moorhen, has adapted well to living in urban environments, often being found in parks and gardens with access to water. It occurs and breeds in Europe, Asia, Australia, and Africa. The species has recently expanded its range into New Zealand. It is resident in the milder parts of its range, but migrates further south and west from much of Asia in winter as the waters freeze. It is known to occur as a vagrant in North America.
