How does a bird being in flight show Newton's third law of motion? :3?

Alright, I need to know, QUICKLY, how a bird being in motion uses Newton's third law of motion. My brain is being horrid at the moment, and refuses to comprehend anything. So, please assist! Thanks a ton, and QUICKLY! :3How does a bird being in flight show Newton's third law of motion? :3?The bird pushes down on the air with its wings, and the air pushes with the same force on the bird. We know that air is almost mass less so it's inertia is a lot lower so it accelerates faster than the bird does up, but none the less the air still must exert the same force as the bird down on the air as the air does on the bird.
