In Littleton, MA at the Hartwell Reserve Conservation Land I saw a young tom turkey and, when it moved off, I scared up its companion - some kind of peacock. At first I thought it might be a hen peacock but this aquamarine neck feathering is on the males. It had that little crown of bare feather shafts topped with tufts.The back, wing and tail feathers were more turkey-like than peacock-like: dark brown and barred. I am perhaps mis-remembering that a peacock has rust brown wing feathers - which this did not. Maybe it was just a juvenile male peacock hanging with a turkey. Or maybe it was a hybrid.
Sorry I could not get a better picture. There were several moments when both birds were in plain view but my camera was busy "processing" the previous picture.
