Canon 7D2, 400mm f4 DO IS II, 1.4xTC III, speedlite 600 EX-RT, tripod
ISO 640, f6.3, 1/1000s
Shot this with a single flash and I removed the flash pin light from the eye. I plan on adding multiple flashes to help increase shutter speed and allow narrower aperture for DOF - this should help with overall freeze motion/sharpness on the bird.
Background is grass lawn.
