Is that mud in its bill? Nest building I guess. Neat greyish/baby powder blue plumage. HA could be a tad better IMO, and the fine detail seems a bit coarse...was this cropped alot? Nice BG - I'd only tone down the lighter areas directly in front of the bill, and the faint horizontal line along top of frame.
Yes I have to confess to trying to make a silk purse out of a sows ear, but it was a bird I had not seen before. The lighting was poor and we were too far away, the crop was great resulting in the poor IQ.
Daniel,
It is mud, and probably something to do with nesting, I had no idea what was in the mouth until I processed the image.
