I realize this is not a "clean "image but I wanted to show the behavior captured here. The spat lasted a long time ~ 3 minutes and I got a lot of frames but this is the most "painful" frame.
Very dark and overcast morning.
Canon 1 DX
600mm
SS 1/2000 ISO 2500 F 5.6.
Small crop to 80% FF and cloned out 1 twig behind wing and trimmed back one of palm fronds near bill.
Comments and critiques always appreciated and learned from with thanks,
Gail
