Mama Buzzard wants her children to learn to bring back meat for dinner. One buzzardling is shy and has to be kicked out of the nest. He's told to at least bring back a rabbit.
Foundling Beaky Buzzard is adopted by a couple of polite, English sparrows named Monte and Gwendlyn. When Monte tries to teach lame-brained Beaky to catch a chicken, Beaky's ineptitude results in Monte being repeatedly struck with a mallet and caught in a grenade explosion.
In an African jungle, hungry Beaky Buzzard can't wait until Leo the Lion is decently deceased before trying to devour him. Leo takes a rocket to the Moon to try to escape Beaky, but finds Beaky already there waiting for him.
