Thank you so much for your kind words.
The setting are:
1DX II + Canon 500 f/4L IS II
I took this shot while kayaking.
I tell folk we only see Red-tailed View attachment 197958 hawks here and only in the sky so I have no experience with ID. Trying to follow some swallows I saw this and snapped it but at 800mm and 1/1000 and great distance it's very poor - still if anyone can help with ID I'd appreciate it.
