A question for the professionals, How is it possible to produce this mutation step by step?
The owner said it's called Blackhead Emerald light form Cockatiel

Wow!!! 😮😍. He/she is gorgeous!!! I know that emerald and whiteface are recessive so both parents would have to be whiteface emerald in order to get any emerald chicks. As for that particular type, I'm not really sure, sorry. He also looks split to pied.

Wouldn't the male be the one on the right since he has a bright yellow head? They are both very stunning! Unfortunately, I don't know much about that mutation so I won't be able to help you, sorry.
