I like the inclusion of the handrail, and the clarity in the foreground in contrast to the background. The bird is an interesting subject, standing out, yet camoflaguing with the background.
Wow! The image clarity is superb. You seem to have caught him(?) at the moment when he's puffing up. The colors and contrast are excellent. My only suggestion lies in the composition. The bird should be to the left looking into the frame. Other than that it's beautiful
