Few, if any, ducks have so many popular names as this species, which is known as spine-tailed, heavy-tailed, quill-tail coot, stiff-tail, bristle-tail, sleepy-duck, sleepy coot, fool-duck, deaf-duck, shot-pouch, daub-duck, stubble-and-twist, booly-coot, blather scoot, hickory-head, greaser, paddy, noddy, paddy-whack, dinkey, hard-tack, etc., according to the locality or the particular individual who is asked to name the species. It has characteristics which justify the use of any one or all of these names. Its range is the whole of North America, which extends south to Guatemala and Colombia, Cuba and other West Indian islands. Probably no North American duck has so extensive a breeding-range as the present species, since it breeds as far south as Guatemala, perhaps even farther; as far north as Great Stone Lake, York Factory, and other localities in the sub-Arctic portions of the continent, and from the Atlantic to the Pacific. According to Professor Cook it winters from southern Illinois southward. This duck seems to be equally fond of salt, brackish, and fresh water. In the Southern states it is found in great flocks. Its flight is rapid, with a whirring sound, occasioned by the concave form of the wings. It rises from the water with considerable difficulty, being obliged to assist itself with its broad webbed feet, and for that purpose to run on the surface for several yards. From the ground, however, it can spring up at once. It swims with ease and grace, is expert at diving, and when wounded, often escapes in this way, hiding in the grass if there is any accessible. The locality usually selected for a nest is some deep, sluggish stream, lake, or pond, and the nests are always built close to the water's edge, being composed of reeds, dry rushes, and grass. The structure is often made so that it will float, similar to a grebe's nest. It is asserted that this bird prefers the abandoned nests of coots for nesting purposes to those constructed by itself. The eggs appear large for the size of the bird; they are grayish white, oval in shape, with a finely granulated surface; sizes range from 2.35 to 2.50 long by 1.70 to 1.80 broad. Audubon says that the adult female in summer presents the same characteristics as the male. He describes the male one year old as having a similar white patch on the side of the head; upper part of head and hind neck dull blackish brown; throat and sides of neck, lower part of the neck dull reddish brown waved with dusky; upper parts as in the adult but of a duller tint, lower parts of a grayish white.
