Excellent composition, colors, detail and background Ely!
The white collar seems to be not blown too severely, so this can be recovered in RAW conversion easily. I see that you used 1/1000 sec, f/8 and ISO 800. I agree on the Av to get more DOF, but I'd probably shot at 1/250 sec and ISO 200. This would yield a wider dynamic range than ISO 800 - the highlights will be easier to recover and I can push the shadows more without excessive noise.
Wow that was a simple solution to a problem that I encounter so often. I have to learn to be calm and not get excited when I encounter situations like when the bird landed right in front of me while I was taking the picture of another bird. I have come to realize why my ISO is higher than normal. I start out early in the morning and sometimes my ISO is as high as 3200 but more often I start at 1600 as there is not enough light to shoot at 1/100 sec. As the light improves I lower my ISO once I see that my speed goes beyond 1/400 sec. I guess when the bird landed so near I did not have the presence of mind to change the settings and just started shooting when I got him focused. Thank you again Romy for your valuable lesson.
