I really like the pose of the bird with the berry. The head angle really pulls one to the bird. Having the bird a little more off centre would have aided more. It looks like the light was quite harsh and it would be worth toning down the highlights on the berries. I also find the whites are lacking detail.
I agree with Ben and Asad's comments, and I feel the bird should be further over to the left, and the large oof orange object at lower left is rather distracting.
You have a great bird with nice behavior and environment, and the berry in his beak is a huge plus. It's unfortunate that this photo was taken in such harsh light. Would like to see the bird moved out of the center (to the left) and the head could use a little more sharpening.
Good critiques by the previous posters. Always tough to photograph in such harsh lighting conditions - especially a contraty bird such as this. I like the berry in the bill:)
