Doesn't look very good to me. Possibly back focusing a little but difficult to tell from those shots, the first 2 are much too high an ISO value to make a judgement, in the other 2 it is difficult to tell what you are focused on.

Post some more shots taken at ISO100 of subjects that have some depth so that we can see where the focus point should be.

Thanks for the response, I don't have much with ISO 100, should I be having?

Here is one I thought I focused on the bird, at ISO 250 but it didn't. So it does look like I have a front/back focus?

I'm sorry, I just rechecked this picture in DPP and I had all focus points enabled to capture when the bird flies, the auto focus latched focus on the green leaves to the right of the bird. So this may not be the right picture to determine focus issue.

I may have to end up doing a focus test in the lines of - Canon Focus testing
