The versteri are quite Scares in this country in captivity, only seen a photo of a pair that was in captivity in Denmark. I believe they stay more wild than the yellow and orange bellied and are harder to bread but do not make good pets. I wonder if @Parrot797 will have more knowledge
Gulliver has a few amber shade feathers but mostly yellow. I hve also seen mixes between Meyers and Sennie. Gulliver also has little dark bits on his chest, I have read that can be from poor diet but not 100% sure.
