How fast is the Sony a9 III? Photographing red kites in flight...

How good is the new Sony a9 III for wildlife photography, in particular, for photographing fast-action subjects like birds in flight? Do features like global shutter, pre-capture and a top frame rate of 120fps translate into better photographs? To find out, I took the camera to Wales and used it to photograph red kites.
