Would take some of the top away Probably crop to the dark line or close to it That top part sure is an attention grabber away from the bird. Can also place the bird further back in the frame. I like the exposure on the bird, wings look very nice, can select the head area and lighten some. Bg with all the little shorebirds is interesting.
I like the setting and wing position. I would put him further to the right in the frame, crop some off the top, apply some CCW rotation and wish the sun would have been behind you.
