I didn't have much opportunity to shot any of these beautiful birds in flight. This one was still fairly far away, and this shot is cropped a fair amount, explaining its having less detail than I'd like. Canon 100-400 with Canon 1.4x II Teleconverter at 435 mm, ISO 200, f/8, 1/640 second, Wimberley Sidekick/Arca Swiss Ballhead/Gitzo Tripod (manual mode, manual focus).
