Almost everyone has wished at one time or another to fly like a bird. Just the thought of soaring above your city or town gives us a reason to envy these feathered animals. So what makes birds so special that they are able to take to the air? In this video, I explained the physical adaptions birds made and the biomechanics of bird flight so that you will have a better understanding of bird flight :D

▶️0:00:14 Physical Adaptions
▶️0:00:25 Hollow Bones
▶️0:00:37 Material - Keratin
▶️0:00:48 Short Rectum
▶️0:00:58 Other Physical Features
▶️0:01:14 Biomechanics of Bird Flight
▶️0:01:24 Different Forces Acting on a Flying Bird (Weight, Drag, Thrust, Lift)
▶️0:02:21 Lift - Airfoil (a.k.a. Aerofoil)
▶️0:02:35 Lift - Bernoulli's Principle

👍This is an awesome experience and I am thankful that my friends told me about this. I admit that I crammed this video in the last couple of weeks before ddl but I did my best.

💖A big shoutout to all the participants - you did GREAT! Good luck to everyone :))
