The Legend of the Boy and the Eagle (1967)

"An Indian boy and a wild eagle embark on a strange adventure!"

Eagles are the channel to the spirit world for a Hopi Indian boy who defies tribal law and frees a sacred, sacrificial eagle. He is banished from his village to the wilderness, but the eagle teaches him hunting skills and cares for him. He eventually returns, only to be bullied and taunted by the other village boys.
