An American Indian tells about a brave who found an eagle's egg and put it into the nest of a prairie chicken草原鸡. The eaglet小鹰 hatched with the brood一伙，一窝 of chicks and grew up with them.
All its life, the changeling（低能的） eagle, thinking it was a prairie chicken, did what the prairie chickens did. It scratched in the dirt for seeds and insects to eat. It clucked（咯咯叫） and cackled（咯咯叫，喋喋不休）. And it flew in a brief thrashing of wings and flurry（慌张，疾风 ）of feathers no more than a few feet off the ground. After all, that's how prairie chickens were supposed to fly.
Years passed. And the changeling eagle grew very old. One day, it saw a magnificent（壮丽的，宏伟的） bird far above in the cloudless sky. Hanging with graceful majesty（威严，雄伟 ）on the powerful wind currents, it soared with scarcely a beat of its strong golden wings.
"What a beautiful bird!" said the changeling eagle to its neighbor. "What is it?"
"That's an eagle - the chief of the birds," the neighbor clucked. "But don't give it a second thought. You could never be like him."
So the changeling eagle never gave it a second thought and it died thinking it was a prairie chicken.
