Aussie Finch Forum

I managed to breed these two birds last year from 2 greenbacks. I purchased the parents as split blues. I have not had dilutes or limes before and have not seen enough mature birds on the net or anywhere for that matter to understand which mutation they are. I think their backs are a lime colour especially when in sunlight. The cock is showing split for aussie yellow and they have other split AY siblings( no blue ). The parents are definitely greenbacks and have no aussie yellow markings showing but are certainly split for AY as the young show. It would be nice to see your opinions

If the parents were normal phenotype, they must be recessive dilutes.

...and possible split blue + a split AY.

Thanks Tiaris. I am not sure but I think both the limes and aussie dilutes are recessive from things I have read. My issue in that case is what the real visual difference is between the two. It would be nice to see a pic of the two side by side which I have not seen. These birds are recessive though and I have paired their parents again this year. They have just fledged 4 split AYellows...my first young fledged for the year

Were the parent birds purchased locally?

did the breeder you get them off have recessive dilutes in his aviaries?

Yes Misso and he did have some recessive dilutes

Don't know enough about the mutations to say anything accept to observe that it dilutes all black the same as euro yellow does.

Only the same as double factor euro yellow, which cannot be produced from normal phenotype parents.

Does anyone have any pics of a mature lime?

My point was that both double and single factor euro yellow do not show any black feathering and neither do these birds. So just as the euro yellow is visually affected by a single gene inheritance, so could these birds be?
