What's amazing to me is how birds naturally have mastered a flying wing. They use a single stabilizer and wing twisting to control yaw, pitch, and roll. We have to use fixed controls that pivot and normally three sets for each axis.
The other thing that amazes me is to watch birds, even the small ones, master gusts and crosswinds and glide it in to land on a fence or other very small target.
Years before we figured out the CV-22, birds could twist everything to combine horizontal flight with near vertical flight. And if you are looking for precision, watch a hawk go after something. Low and fast over the ground, pitches up at the right time, and dives down on the victim. Amazing stuff!
