Hi Kasra, I havent seen this species before - I really the colours on him, the three colours of red, black and grey work well together. He sure has caught enough to feed on. I feel the bird is a little too large in the frame, and comp wise, a little tight below.
Please remember to post your camera, lens and settings.
This image is really working for me. I love the pose on the bird and its colors work so well with the rock. The pose is awesome with the partly spread wing, the head turn and the prey is a huge plus. Well done.
Magnificent looking bird, and capture. The exposure looks right on, with wonderful feather detail. I agree with Stuart, the bird could use a bit more room in the frame. Insets in the beak a plus.
