Length of foot is largely dependent upon length of neck. This is illustrated by the Herons, and is particu- larly well shown by the long-necked Flamingo, which has a foot twelve inches long. Its toes are webbed, and it can wade in deep water and search for food on the bottom by immersing its Ions* neck and its o head. In the tropical Ja- canas the toes and toe- nails are much length- ened, enabling the bird to pass over the water on aquatic plants. I have seen these birds walking on small lily leaves, which sank be- neath their weight, giv- ing one the imj^ression that they were walking on the water (see Fig. 10). Many ground-feeding l)irds use the feet in scratching for food ; Chickens are familiar examples. Towhees and. Fig. 14.—Flamingo, showinjgr relative length of legs and nock in a Avading bird.
