Flap Your Wings

Flap Your Wings, by P.D. Eastman
When a strange egg appears in their nest, Mr. and Mrs. Bird kindly take it upon themselves to raise the baby bird inside. But when the egg hatches, the Birds are in for a big surprise--Junior is the oddest-looking baby bird they've ever seen! In fact, he looks more like a baby alligator than a baby bird, and they have to wonder... how can Junior fly without wings?
