Hey Jim,
I would be very concerned about this new behavior from these Kestrels. It is very possible that you are being stalked. I would not suggest open confrontation. Instead, just head to the local precinct and speak to the police about it. They may tell you that you will need an order of protection.
On a serious note, beautiful shot. Very well done. Are the colors from pp or are they naturally that rich and saturated? I believe in the last kestrel shot that you beefed up the colors a bit.
James
