The Eurasian coot (Fulica atra), also known as coot, is a member of the rail and crake bird family, the Rallidae. The scientific name is from Latin; Fulica is "coot", and atra is "black". It is found in Europe, Asia, Australia and parts of Africa. The Australian subspecies is known as the Australian coot.

The coot breeds across much of the Old World on freshwater lakes and ponds. 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

The Eurasian coot is 32–42 cm (13–17 in) long and weighs 585–1,100 g (1.290–2.425 lb), and is largely black except for the white frontal shield (which gave 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 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.

This is a noisy bird with a wide repertoire of crackling, explosive, or trumpeting calls, often given at night.

The Eurasian coot is much less secretive most of the rail family, and can be seen swimming on open water or walking across waterside grasslands. It is an aggressive species, and strongly territorial during the breeding season, and both parents are involved in territorial defence. During the non-breeding season they may form large flocks, possibly related to predator avoidance.

It is reluctant to fly and when taking off runs across the water surface with much splashing. It does the same, but without actually flying, when travelling a short distance at speed in territorial disputes. As with many rails, its weak flight does not inspire confidence, but on migration, usually at night, it can cover surprisingly large distances. It bobs its head as it swims, and makes short dives from a little jump.

This species builds a nest of dead reeds or grasses, but also pieces of paper or plastic near the water's edge or on underwater obstacles protruding from the water, laying up to 10 eggs, sometimes 2 or 3 times per season. Usually only a few young survive. They are frequent prey for birds such as herons and gulls.
