Robin- returned or a new one?

I have not had a robin in my garden since March. I dont know if this is the same one or not. This is a picture of the 'old' one if you want to compare and see if think it is the same. The other picture has been photo-shopped by my photoshop techer who said, 'I can make that look better', - then did about 20 seps that I could not follow. So he might look a little different anyway- picture here.

I know robins are territorial.
