(this may sound stupid but) how do birds somehow flap their wings fast and hard enough to fly(sorry for a dumb question). (repost bc one typo just got my entire post deleted)

I’m not an expert, but I know that nearly all birds have a “wishbone” near the top of their breast. This y-shaped bone acts as a slight spring, so that contracting the wing muscles compresses it, then when released it helps push the wings back up.
Think of “twanging” a thin strip held on one end. It will vibrate faster than you need to hit it to keep it vibrating. Not exactly the same with birds but gives a sense.
