. Adventures with animals and plants. Biology. PROBLEM I. The Kinds of Anmmls birds that wade or swim, perching birds, and birds that cannot fly. Birds of prey. These are the eagles, hawks, vultures, and owls. Their wings spread wide and firm; their talons (claws) are cruel, curved daggers which can be driven deep into the body of a small mammal or other bird; their strong beaks used for tearing flesh are hooked and sharp. Some hawks, eagles, and vultures are easily recognized in flight because of their remarkable ability to soar, that is, to remain aloft with almost no movement of the wings.

Some hawks, eagles, and vultures are easily recognized in flight because of their remarkable ability to soar, that is, to remain aloft with almost no movement of the wings. They do this by taking advantage of the air currents. In spite of common belief, birds of prey, with few exceptions, are useful to man. Their natural food is rabbits, field mice, other small mammals, and even certain species of insects which are destructive to crops. The vultures and some of their rela- tives are scavengers; they feed on the dead and decaying flesh of animals. of the Earth 21 Scratching birds. These live on the ground and scratch for seeds and small insects; such birds are the common fowl, the grouse or partridge, and the turkey. Some of these birds are strong and swift flyers, too, but for the most part they rely on their legs instead of their wings. Domestic fowl such as chickens, ducks, and turkeys have prac- tically lost the power of flight. Birds that wade or swim. These are, mostly, large birds. They squawk and call hoarsely but never sing. Their food comes from the water and they spend much of their time in the water or on it. The storks, the herons, the cranes, and the flamingos (fla-ming'gos) wade. Their tall legs keep their bodies well out of the water and their long pointed beaks and flexible necks make it pos- sible for them to snatch the frogs or fish that make up their diet. Among the swimming birds are the ducks, geese, and swans. Their legs are Forehead Upper mandible Lower mandible Throat Wing coverts Breast Crown Claw Abdomen Scales Back Scapu
