You continue to amaze me with your captures and improved techniques. Just compare what you're doing now with 6 months ago and I think you'll even surprise yourself (much less everyone else).
Having been down there at the same time these were taken, I know how difficult they were. I tried several times in different lighting conditions to get a decent shot of the glossy ibis, and none of them came out nearly as good as the one you posted here. Great job!
