Hey Humberto, not sure why your image did not show properly. There was a link to it...did you use the "Manage Attachchments" button? Anyhow, I've fixed it for you...before posting always click "preview" to make sure all will be good:S3:
I like the nuthatch itself...sharp as posted with lots of details. Perhaqps a bit light. I also like the open bill. Bg is awesome - great colour and hues of green. I'm not crazy about this guy perching so far behind the trunk though. This has hidden a good chunk of its body, and the tree is rendered completely OOF by being way out of DOF range. I'm sure you didn't have time to move left, so it was just a matter of hoping this guy perched more on this side of the tree.
