Read the legend titled "The Bird Chief." All the birds were called together. To them was said, “Whichever one of you can fly farthest into the sky shall be chief.”

All the birds flew to a great height. But Wren got under the thick feathers of Eagle and sat there as Eagle flew. When all the birds became wing-tired, they flew down again; but Eagle flew still higher. When Eagle had gone as far as he could, Wren flew still higher.

When all the birds reached the ground, Eagle alone returned, after a great while. Behold! Wren only was absent. So they awaited him. At last he returned. Eagle had too highly been thinking of himself, being sure of being made chief; and behold! Wren was made chief.

The purpose of this legend is most likely to teach a lesson related to

the intelligence of different birds.
the dangers of being too proud.
the importance of doing your best.
the thrill of getting ahead in life.
