Science, in its classification and naming of birds, has rendered it quite easy for any one to recognize unmistakably anywhere any specimen we have pictured in our magazine. In some sections this interesting Duck is known as the Mud-hen, in others the Crow Duck, in still others as the Ivory-billed Mud-hen, but with the picture in hand or in mind, one need never call the bird by any other than its correct name, the American Coot. The European Coot resembles it, but its average size is slightly larger, its habits, however, being in all respects like those of its American relative. Davie says that this is the water fowl that the young sportsman persists in shooting as a game bird, but at a riper age he does not "hanker" after its flesh. The habitat of the Coot is very extensive, covering the whole of North America, middle America, and the West Indies; north to Greenland and Alaska, south to Veragua and Trinidad. The Coot is a summer resident in large marshes, and is not often rare in any marshy situation. It arrives the last of April and remains until the last of November. It nests at the same time as the Florida Gallinule (see BIRDS, Vol. I, p. 121,) but shows a greater preference for reed patches, in which its nests are usually located, often in from two to four feet of water. The nests are generally larger than those of Gallinules, and rarely composed of other material than the dry stalks of reeds and grasses. They are placed on the ground, just out of the water or on floating vegetation. Some times immense numbers of Coots breed together. The eggs are clay or creamy-white, uniformly and finely dotted all over with specks of dark brown and black. From six to twelve eggs have been found in a nest. As winter approaches and the marshes and shallow pools become covered with ice, these birds congregate in immense flocks on the rivers and small lakes, and remain until cold weather closes the streams.
