Birds don't fly by flapping up and down - they flap down and back, then fold the wing and pull it forward and up.

If you just flap and up and down you move up and down, but you don't fly. You need motion to cause forward acceleration, not just up and down bobbing.

Fake, it's simply impossible for the shown flapping method to cause him to fly.

See here: http://www.youtube.com/watch?v=PSikfcJezy4#t=180s and notice how the bird folds the wings as it pulls them up, then spreads them as it pushes down. The folded wings give less resistance to the air than the spread ones, and that difference lets it fly. Without that you can't fly by flapping. To move forward it also has a front back motion that is harder to see in the video, but is still visible.
