3. The heron lives on frogs and fish. With its long legs it can wade out in the shallow water, and its toes spread out so it does not sink in the mud.

4. When ready for breakfast, it wades in where the water is half-leg deep. Then it stands so still that the fish, the frogs, and the water-rats will swim all about its legs.

5. All at once, as quick as a flash, down plunges the beak, and up comes a frog from the water, and down it goes, whole, into the long throat. Another comes along, and goes the same way.

6. When it has had enough, it steps ashore, cleans its feathers with its long bill, and goes to sleep standing on one leg. Its middle toe has a double nail, and with this it scratches off the down that sticks to its bill after cleaning its feathers.

7. The heron flies high in the air. When flying, its legs extend out straight behind, and its neck curls over and rests on its back.

8. The stork is another bird with long legs that wades in the water and eats frogs and fish. In Holland, the stork is so tame that it lives in the farm-yard, and often builds its nest on the house-tops.
