An eagle sometimes lives to be over one hundred years old. Many years ago it was said that an eagle never dies of sickness nor of old age, but that its beak grows out of shape in its last years so that it cannot eat.
All people have admired the eagle. The Indians of America have always liked to wear the feathers of the king of birds, and in Scotland the chief was known by the feather of an eagle which he wore in his bonnet.
It often happens that a young eagle looks much larger than its father or mother. This is because the first feathers of the wings and tail are longer than the ones that grow in their place when the young eagle has once shed them. The young eagle is also darker than the old one. This is why some people have made mistakes in writing about them without knowing a young eagle from an old one.
Eagles of the same kind are not always of the same color. Some are darker than others and the markings are not alike. Some young eagles shed their downy feathers early and wear the dress of grown-up birds. Others keep some or all of their baby feathers five or six years. And there are some very old eagles still wearing some of the downy feathers of their first dresses.
Eagles kept in cages lose some of their fierce ways and change the colors of their dress. But they do not forget that they are eagles. A large cat once went under the bars of an eagle's cage to get the meat which had not been eaten by the bird. Down came the eagle, tore the cat to pieces, and ate him in a hurry.
The bald eagle is very fond of fish. I have seen him on a bright day sailing high above a lake where I was fishing. He was so slow and lazy that I did not think he was fishing too. But when he saw a fine large fish near the top of the water he came down like a flash, struck his claws into the fish, and flew away to his mate in a tree upon the land.
Sometimes the eagle gets the fish hawk to do the work for him. Waiting on the branch of some tree upon the shore he sees the fish hawk flying about over the water looking for his prey. As soon as a fish has been caught and the hawk is coming ashore to eat it, the eagle frightens the hawk so as to make him drop his fish. Then the eagle catches it again before it strikes the water.
It is because he is such a robber that some of the people of America did not like to have him chosen to be the bird of our nation. They felt that we ought to have a bird that is good towards all the other birds.
A poor family once lived for a long time by robbing an eagle. The father climbed to the nest and took away the meat which the eagle brought for its young. Every day he got food for his family from the eagle. When the young birds were almost ready to fly he cut the feathers from their wings so they could not leave the nest. Then he tied them in to make sure of his own meat every day. The young ones cried harder when tied and the old ones thought they were hungry and brought them more flesh.
