The Amazing Science of How Birds Fly | Wytham Woods
Flight is perhaps the most complex form of movement in the animal kingdom. Researchers Lydia France and Graham Taylor at Oxford’s Wytham Woods are looking at exactly how it works, while branching out into how birds perch.

So how do they fly?
0:8 😂that perspective made me laugh silly cz I do sleep to bird sounds once a while.
I can understand how they lift, with the downwards movement of their wings, and I can understand how they land, putting their bodies in a very high Angle of Attack position, so all that air from the flapping of the wings heads forward and therefore stops them... What is very difficult for me to visualize is how they manage to propel themselves forward, if the movement of the air produced by their wings is downward... In an airplane you have a propeller that propels you at the same time wings provide lift, but how do birds achieve so much forward speed? The ornithopter devices built by man manage to float, but they barely move forward... Maybe their wings in level flight are in a certain negative AOA position? Perhaps the movement of the birds' wings is not only vertical, but in some way they make their wings zigzag, just as a dolphin moves its tail in water? Thank you!!

Short answer: God designed it.
