The American coot is closely related to the Eurasian coot (Fulica atra), which occupies the same ecological niche in Eurasia and Australia as the American coot does in North America. [ citation needed ] Eurasian coots can be distinguished from this species by the absence of a red callus above the bird's frontal shield .
Waterfowl flyways in the United States. The Atlantic Flyway is in violet. The Atlantic Flyway is a major north-south flyway for migratory birds in North America. The route generally starts in Greenland, then follows the Atlantic coast of Canada, then south down the Atlantic Coast of the United States to the tropical areas of South America and the Caribbean.

Migration is the regular seasonal movement, often north and south, undertaken by many species of birds. Migration is marked by its annual seasonality and movement between breeding and non-breeding areas. [16] Nonmigratory bird movements include those made in response to environmental changes including in food availability, habitat, or weather.
His success sparked the interest of the newly formed American Ornithologists' Union (AOU), who convened a committee on the distribution and migration of birds and chose C. Hart Merriam to be its chief. The AOU expanded the volunteer network to include the entire United States, Canada, and a portion of the West Indies. The program outgrew the ...
Coot species that migrate do so at night. The American coot has been observed rarely in Britain and Ireland, while the Eurasian coot is found across Asia, Australia and parts of Africa. In southern Louisiana, the coot is referred to by the French name "poule d'eau", which translates into English as "water hen". [11]
In some species, it is longer than the head (like the clapper rail of the Americas); in others, it may be short and wide (as in the coots), or massive (as in the purple gallinules). [5] A few coots and gallinules have a frontal shield, which is a fleshy, rearward extension of the upper bill. The most complex frontal shield is found in the ...
The main endpoints of the flyway include the Canadian Prairies and the region surrounding the Gulf of Mexico; the migration route tends to narrow considerably in the Platte River and Missouri River valleys of central and eastern Nebraska, which accounts for the high number of bird species found there.

American coot. Order: Gruiformes Family: Rallidae. Rallidae is a large family of small to medium-sized birds which includes the rails, crakes, coots, and gallinules. The most typical family members occupy dense vegetation in damp environments near lakes, swamps, or rivers.
