Some more information which seems related to the birds pictured in the original post:

The pictures above are of birds from a long-term hybrid program -- thus they are not pure Amherst, but were bred back to Amherst for enough generations that the birds have lost virtually all Golden characteristics, save the mutations the breeder wished to transfer. But the breeder's commentary below mentions seeing unusually-colored Amherst pheasants in Thailand that were claimed to be pure.
