You know this is how it always seems to end. Me spending all my time and wit on how to get the shot, while my subject just casuallytakes off for no good reason. When your 50'-60' below them and they know you can't fly, how are you considered a threat???
I have seen this Red-tail for several weeks and finally had some time to check him out. Seems he doesn't work with unknowns like me. I must not be good enough. I was quiet, slow moving, and above all no threat. So why do they fly off? I had good focus, and not the worst angle either, considering how far up he was.
I will get more then this once I get my hands on somebetter glass.
