Excellent image. I love that kind of animal portrait - the colours of your flamingo are a lot stronger than we get here, but likely because of what they are fed.
You image certainly reinforces not only your skill, but the fact that the R6 and EF 100-400II are still very capable pieces of gear.
Kudos!
cheers, TREVOR
