A member of the family Rallidae, it has three subspecies in addition to the nominate: Fulica americana alai, F. a. caribaea, and F. a. Probably migrates mostly at night. American coot. [4] These subspecies, however, are sometimes considered to be their own separate species. The number of birds that stay year-round near the northern limit of the species' range seems to be increasing. To get airborne, coots typically have to beat their wings while running across the water for many yards. A familiar black bird of our lakes, ponds and rivers, the Coot is widespread; look out for its large and untidy-looking nest on the water in spring.

[23] First the male chases the female. [9] Thus, it seems that the modern-type American coots evolved during the mid-late Pleistocene, a few hundred thousand years ago. [4], The coot mating season occurs during May and June. [22] Coot mate pairings are monogamous throughout their life, given they have a suitable territory. Gruiforme Order – Rallidae Family. The American coot — Fulica americana, a gangly, awkward member of the rail family — is common on lakes and wetlands throughout much of North America, and folks frequently chuckle at the seemingly silly behavior of mud hens. 6-11, sometimes 2-12. This species can be seen in large flocks. Sometimes seen offshore, especially in winter if freshwater areas are frozen. [18][19], The American coot is a highly gregarious species, particularly in the winter, when its flocks can number in the thousands. The American coot typically has long courtship periods. They learn to recognize their own chicks by imprinting on cues from the first chick that hatches. May winter as far north as open water permits. BIOMETRICS : Length: 36-39 cm Wingspan: 70-80 cm Weight: M: 900g – F: 770 g. DESCRIPTION: Very common on lakes, ponds and rivers of the Old World, the Common Coot has expanded its range to other countries and continents. They do fly, however. Coot can be seen mainly on freshwater lakes, gravel pits, reservoirs, rivers and town park lakes when deep enough. The black stripe will appear on it's beak and the red spot between the eyes will become much more visible. Mammalian predators (including red foxes, coyotes, skunks and raccoons) are even less likely to predate coot nests, though nests are regularly destroyed in usurpation by muskrats. Food resource constraints may limit the number of eggs parents let hatch, or the remaining eggs may not provide enough visual or tactile stimulation to elicit incubation behavior. Egg desertion is a frequent occurrence among coots because females will often deposit more than eight eggs. Nest site is among tall marsh vegetation in shallow water. Young probably able to fly at about 7-8 weeks after hatching. Chicks that do not match the imprinted cues are then recognized as parasite chicks and are rejected. Though commonly mistaken for ducks, American coots are only distantly related to ducks, belonging to a separate order. Young: can swim well soon after hatching; follow parents and are fed by them. There are three general types of structures: display platforms, egg nests and brood nests. [23], Females deposit one egg a day until the clutch is complete. In fact, coots may locally comprise more than 80% of the bald eagle diet. When coots run across the water, they kick up white splashes that can be seen from long distances. Brood size limits incubation time, and when a certain number of chicks have hatched the remaining eggs are abandoned. Because they are found in wetlands, scientists use them to monitor toxin levels and pollution problems in these environments. Floater females without territories or nests use brood parasitism as their primary method of reproduction, if they breed at all. New research shows that these apex predators wait for food to fall out of the sky during migration. Food supply is the limiting factor to chick survival and starvation is the most common cause of chick morbidity. Coots are tough, adaptable waterbirds. [6], The first evidence for parental selection of exaggerated, ornamental traits in offspring was found in American coots. Their take off is rather slow and labored in appearance. After a pair bond is cemented, the mating pair looks for a territory to build a nest in. Spring migration to breeding ranges occurs from late February to mid-May, with males and older birds moving North first. Lives of North American Birds. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too. As this juvenile gets a little older, the frontal shield and beak will turn white. Birds from temperate North America east of the Rocky Mountains migrate to the southern United States and southern British Columbia. [31], When a parasitic female lays her egg in a host female's nest, the host female experiences a deposition rate of two eggs per day. [2], The American coot is a migratory bird that occupies most of North America. Photo: Howard Arndt/Audubon Photography Awards, Great Egret. Photo: Mark Eden/Great Backyard Bird Count. Runners make great targets as they patter across the surface. Just look at those feet! Buff to grayish with brown spots. [26], Hatch order usually follows the same sequence as laying order. can swim well soon after hatching; follow parents and are fed by them. Other females may engage in brood parasitism if their partially complete clutches are destroyed. [4], American coots are found near water reed-ringed lakes and ponds, open marshes, and sluggish rivers. Unlike the webbed feet of ducks, coots have broad, lobed scales on their lower legs and toes that fold back with each step in order to facilitate walking on dry land. Also, stressed males go puhk-cowah or pow-ur while females call cooah. Experimental manipulation of chick ornamentation by clipping the bright plumes has shown that parents prefer ornamented chicks over non-ornamented ones. The coot would rather swim to avoid danger than to fly. One study showed that 68% of destroyed clutches are eventually replaced. [2], Much research has been done on the breeding habits of American coots. Incubation by both sexes, 21-25 days. [30], The American coot has a mixed reproductive strategy, and conspecific brood parasitism is a common alternative reproductive method. Even after getting airborne, coots usually fly low and regularly land quickly, maybe just around the next bend. Then, the female moves to the display platform and squats with her head under the water. The National Audubon Society protects birds and the places they need, today and tomorrow, throughout the Americas using science, advocacy, education, and on-the-ground conservation. Sexual intercourse usually takes no longer than two seconds.[23]. Text © Kenn Kaufman, adapted from However, there is no difference in clutch size between older and younger females as there is in other avian species. It is possible to induce a female coot to lay more eggs than normal by either removing all or part of her clutch. ; female 15-22 oz. Juvenile American Coot. This page was last edited on 27 November 2020, at 16:14. Usually in flocks, they are aggressive and noisy, making a wide variety of calls by day or night. Can coots/moorhens fly? [32], The American coot, unlike other parasitized species, has the ability to recognize and reject conspecific parasitic chicks from their brood. Females typically do the most work while building. [33], The American coot is fairly aggressive in defense of its eggs and, in combination with their protected nesting habitat, undoubtedly helps reduce losses of eggs and young to all but the most determined and effective predators. Whilst watching Bill Oddie this evening I was reminded of a question that I really don't have a clue about. In taking flight they must patter across the water, flapping their wings furiously, before becoming airborne. [29], Hormones that are passed down from the mother into the egg affect offspring growth, behavior, and social interactions.
