The mechanics of birds are really amazing. This reminds me of a video I saw of a shoebill hunting. The ability to move its body while keeping its head absolutely locked in place is great.

I wish we had some of the bigger birds around still so we could see them fly. Imagine a 110kg Argentavis above your head. It makes me wonder whether engineers will be able to create something to allow individuals to "fly" like one.
