I was wondering this because it seems like hummingbirds have wings that are quite large for something that flaps 60 times per second. Is this kind of flapping only necessary for hovering, or are they like bees that have to flap impressively fast just to stay in the air. Also, if they don't, do you know the amount they would have to flap to hover without needing to move forwards? Just wondering.
