Well for starters, birds bones are hollow, making them much lighter. So when a bird flaps its wings, it displaces air below it, and that air is proportional to the size and weight of the bird itself. By pushing air down, a bird is literally lifting it's own body into the air. I can get more technical if you need me to.

This is highly inaccurate. Please read my answer to understand how it works. What you described is how a plane works, minus the flapping.
