The American Coot is a very common summer resident, found in flocks on marshes and sloughs throughout the state. A very adaptable bird, American Coots may also be seen waddling awkwardly in fields and lawns adjacent to water bodies. They are not graceful fliers either, requiring a long "running" start to get airborne, pattering their feet on the surface of the water.
Habitat
Marshes and sloughs, preferably those that also have adjacent open water. Also may feed on dry land.
Diet
Omnivorous, eating aquatic plants, grasses, seeds, insects, earthworms, small fish, tadpoles, snails, eggs, and fruits and berries.
Behavior
Feeds both in the water and on land. In the water, they may act like dabbling ducks, upending in shallow water, or may dive underwater. They will also readily forage on land near water bodies.
Nesting
May through July. The nest of an American Coot is a floating nest of wetland vegetation such as bulrushes and cattails. The female lays between 4 and 11 eggs, and both parents help to incubate them. When the eggs hatch, the young leave the nest within hours, following the parents who feed them. The young fledge after about 7 weeks.
Song
American Coots have a variety of vocalizations, including various grunts and croaks and a whiny kee-cue, kee-cue.

Migration
Summers throughout much of North America. Northern populations migrate south in the winter, including those in South Dakota. However, they often stay late into the fall and arrive relatively early in the spring.
Similar Species
American Coots can be differentiate from the waterfowl and other birds they tend to hang around due to their unique structure, and basic black plumage with unique light bill. However, they could potentially be confused with the following species:
- Common Gallinule - Common Gallinule are primarily found east of South Dakota, although they are found in the far eastern part of the state on occasion. The white "shield" on the forehead of an American Coot is replaced by a red one on the Common Gallinule. They also have brown tones on their back that are lacking from Common Coot, and white patches on their sides.
- Purple Gallinule - Purple Gallinule are typically not found in South Dakota, as their normal range is far to the southeast. Where the two species cross paths, Purple Gallinule can be differentiated from American Coots by their dark purplish body and dark greenish back, with a red and yellow bill and bluish forehead shield.
Conservation Status
American Coot populations have declined throughout much of their former range due to habitat loss, and that loss is evidently still continuing, as systematic surveys in recent decades continue to show modest declines. However, they are still common to abundant where habitat is available. The IUCN lists the American Coot as a species of "Least Concern".
