Behaviour

Coots dive, dabble and graze on land. They run across the water to take off, and in flocks they splash and squabble constantly. Their toes have broad lobes rather than webs, which help them swim and walk on mud.

Why they matter

American coots are a major winter food for bald eagles on Georgia's reservoirs; eagles often hunt them by making repeated passes until a coot tires. Coots eat large amounts of aquatic plants and are a basic part of the wetland food web.

Reproduction and lifecycle

Nest — A floating platform of plants
Eggs — Usually 8 to 12
Incubation — About 21 to 25 days
Chicks — Black with bright orange-red heads; leave the nest within a day
Flight — At about seven to eight weeks
Lifespan — Several years

Living around people

  • Coots graze lawns by ponds in winter and move on in spring.
  • Bread fills coots without nourishing them.
  • A coot on a road or car park cannot take off from land and needs help.

Misconceptions

  • Coots are ducks. They are rails, with lobed toes and a chicken-like bill.
  • A coot that runs across the water is fleeing danger. Running is how coots take off.
