The following photos were sent to me by the owner and breeder of these birds, Bob Fregeres of Holland.
Bob wrote about these birds :- The inheritance of the blue factor, who is resposible for this new colour varieties, is recessive. People who breed budgerigars and know a lot of inheritance of colours in this birds often think, that also in the Bourke's Parakeet the blue colour is due to the loss of psittacine in the plumage. But he Bourke is not a green bird like the Neophema's. So it can not be a loss-mutation of psittacine. Brown feathers without blue structure become feathers with a blue structure.This is a real mutation factor of the blue structure. This happened in the opaline series. And so the blue opaline did appear. I think the appearance of green one's is very surprising because of the fact that the wild-type Bourke doesn't have green feathers at all. The new green colour is a combination of yellow pigment and the new extended blue structure of the feathers. Bob can be contacted by Email at - fregeres@tiscali.nl Thank you Bob
