THE PIGEON 397 The body is boat-shaped, so as to offer little resistance to the air, and to the same end has an even Features. contour, due to the coat of feathers, which also affords a light and warm covering. A distinct head, neck, and trunk are present, but the tail is a mere.

Since the fore- limbs have the form of wings, the legs must support the whole weight in standing. We shall see that the skeleton is adapted to this necessity. The feet are naked and covered with scales, which are horny and epidermic like those of a reptile, not like those of a fish. There are four toes, which have a wide tread, the first being directed backwards.
