Measuring between 34 - 43 centimeters in length and with a wingspan of 58 - 71 centimeters, the American Coot presents a striking appearance. Its body is covered in dark gray to black plumage, offset by a bright white, short, and thick bill. A prominent white frontal shield adorns its forehead, usually sporting a reddish - brown spot near the bill's top between the eyes. Its legs are yellow, and the toes have broad, lobed scales that fold back while walking on land, a feature that differentiates it from ducks. Juveniles start with olive - brown crowns and a gray body, gradually acquiring the adult coloration around four months old.

These coots are highly adaptable when it comes to habitats. They thrive in reed - ringed lakes, open marshes, and sluggish rivers, showing a preference for freshwater. However, during winter months, they can also be found in saltwater lagoons, bays, and estuaries. Their range spans from southern Quebec's marshes to the Pacific coast of North America and as far south as northern South America. While many birds from temperate North America east of the Rockies migrate to the southern United States and southern British Columbia, some remain year - round in areas where water stays open in winter.

The American Coot is an omnivore with a diverse diet. It dives for aquatic vegetation, especially algae, which forms a major part of its food intake. During the breeding season, it also consumes more aquatic insects and mollusks, which are crucial for the growth of chicks. On land, it forages and scavenges for plant material, arthropods, and even small fish. In addition to their feeding habits, coots are known for their gregarious nature, often forming large flocks, especially in winter. Their ability to swim and walk on floating vegetation, combined with their unique appearance, makes them a fascinating species to observe in wetland ecosystems.
