hi decio,
that is one of the challanges of the 7d going "high" iso (for me everything above 400 on the 7d is difficult to controll) - but i also think that your focus is way up front of the model.

nice colors, good wing position the head is turned away from us but the main issue is that the bird is OOF (focus is on the wood behind the bird).
