This bird has been visiting the garden feeder for about 3 weeks. Photographed it today through the window. It is larger that our usual Goldfinches. Could this be a hybrid or is it a different subspecies of Goldfinch? According to HBW there are about 14 subspecies with one group referred to as "grey-headed" (caniceps) but I cannot find a picture, but these grey headed forms should be in Pakistan/China. So possibly an escaped cage bird? No evidence of a ring but so far I have not had a clear view of both legs.
