I'm about 90% convinced on this ID. I've seen them without a carpal bar as late as Sept.28 here and from some angles it appears that a carpal bar is present and will become more apparent with further feather wear. The nape looks too dark at this point for a Forster's who's crown has turned white already. The nape would be very light gray at this stage with Forsters and there would be an obvious difference between the eventual basic eye patch outline and the fading dark band going around to the nape. The legs are jet black from 3 different angles so that isn't a shadow effect and I can't find any pictures of a Forster's in any plumage with obviously black legs. The tail is shorter than the wings which is consistent with Common and the final nail is the wing tip color. In Forsters it would be light gray and in Common it is black as this bird shows, so the black legs, tail vs. wingtips length and wing tip color are all on the side of Common and the only point I can see as arguable is the mask but this is a variable plumage feature that can be influenced by lighting and heat shimmer in these pictures and is the ONLY thing I've heard used to argue for Forsters.
