These singular birds are natives of South America, and are only three in number, the Homed Screamer {Palamedea cornuta), from Guiana; the Crested Screamer (C'hauna chavaria), from Southern Brazil and Paraguay; and the Derbian Screamer {C'hauna derbiana), from Colombia. They have a horn on the forehead, and very powerful spurs on the wmgs, and these are of great assistance to the birds in defending themselves and their young from the attacks of birds of prey. As a rule, however, theii- habits are gentle and shy, but they fly with great power, owing to their broad and powerful wings. The Crested Screamer is said to be domesticated by the natives, and goes about with the poultry, being, from its large bulk and foi-midable wings, a very able defender of the latter birds. THE SECOND FAMILY OF THE ANSERES.—THE WILD FOWL {Anatida:). In thLs group, containing the Ducks, Geese, and Swans, the feet are very short, and the tarsus is always strongly reticulated in front; the bill is almost straight or, at the most, gently curved, and the tip is convex and rounded at the extremity, in many of the species forming a conspicuous knob, like a finger-nail. The hind-toe, which is present in all, is small, and does not touch the ground. The sides of the face also generally present an angular appearance, having a triangular patch of feathers placed between two bare spaces. The family may be further divided into groups, the Geese, the Swans, the true Ducks, the Scoters and Eider-Ducks, the Mergansers, and the Diving ^'W-^-^.
