3. The RASORES include the common Fowl (fig. 55), Pheasant (fig. 55), Partridge, Turkey, &c.; they feed principally on grain, but occasionally on insects and worms, which they scrape up with their feet; they live chiefly upon the ground, on which they build their nests, but generally roost on trees. Most of this order supply excellent food, the Turkey is famous as a Christmas dish, and is often of a great size; this bird is very plentiful in Central and South America in a wild state, and often attains a large size, weighing 30 or 40 pounds; the natives have a simple and curious method of catching these birds, which are extremely shy, never allowing any one to approach near to them. A sort of cage is built of twigs, large enough to contain many, and having holes close to the ground all round, of a size just sufficient to admit a Turkey when its head is bent down; leading to each of these holes a train of corn is placed, but none within, the birds coming to pick the corn, follow up the line of corn with their heads down, till they are within the inclosure, when finding no more, they raise up their heads and cannot get out, for they have not the sense to stoop their heads, so as to allow of their exit. [Illustration: FIG. 56.--1, HERON (Ardea cinerea); 2, CRANE (Megalornis cinerea).] 4. The GRALLATORES include the Herons and Cranes (fig. 56), which wade into streams and catch fish; these are furnished with long legs, neck, and beak, and when they have gone into the water as far as their long legs permit, they stand still and wait with the head resting on the shoulders and the eyes fixed on the stream, till an unlucky fish approaches near enough, when with a quick stroke they dart at it, and catch it; they are very picturesque objects, standing on one leg (as they commonly do) in some lonely pool or stream. 5. The NATATORES, a very large class of Birds, live almost entirely in the water, they are web-footed and swim beautifully, as the Swans, Geese, Ducks, &c. (fig 57); these feed in general upon the vegetation growing in, and on the margin of the water, also on worms, larvæ, &c.; they have a beautiful mode of rising and flying in a line, when disturbed from their haunts, and this line is maintained for a long distance, and is sometimes double like the letter V, one bird leading and the others following in single file. [Illustration: FIG. 57. 1, SWAN (Cygnus mansuetus); 2, GEESE (Anser ferus); 3 and 4, DUCK and WILD DUCKS (Anas Boschas).] [Illustration: FIG. 58.
