How peculiar? It looks like this little fellow just had a bath! Great focus control, it's hard to shoot photos through tree branches. Colors are excellent, I'm might suggest using the burn tool (in photoshop or any other decent editing program)to take some of the shine off the tree branch. Just a minor suggestion as this doesn't take too much away from the image at all. Excellent capture! Straight to my favorites!
"To photograph is to hold one's breath, when all faculties converge to capture fleeting reality. It's at that precise moment that mastering an image becomes a great physical and intellectual joy."
~ Henri Cartier-Bresson
He just had a bath? He threw up? He's been in a fight? Great capture of the bird. The focus is super and so is the lighting. But, he sure looks worn out.
