Hi,

i am sorry for my question and probably it is very simple but, what is that you call a Australian Yellow???
Is it diferent from, for exemple, the Yellow that we have in Portugal??


Best regards
Gustavo

Yes very different, the Australian yellow is an autosomal reccesssive bird meaning both parents need to have at least one copy of the gene to produce an Australian yellow. It is genetically white breast but sometimes can have purple breast but not a very strong purple more like a mottled lilac colour.
Here's a link to some more info and pics on them.

Personally there one of my favourite mutations

Thats a great link that

Sorry, i am confused.
The Australian Yelow as his back with yellow and with another color????
Is that so???



Gustavo

Gustavo, the gene removes some or all of the melanin that makes the green and purple of the back and breast. Some birds are mottled because not all of the melanin is removed, in others it is almost completely gone from the back and the breast is white. Selective breeding is proving to be successful in removing the mottling and so producing a "cleaner" yellow backed white breasted bird.

Ok
And if we remove all the mottling, who can i distingish a Australian Yellow and a normal Yellow, just by the look??

Ahh, the million dollar question. Thankfully, it only affects white breasted birds it seems as removing the green off the back removes the colour from the breast. Once that happens the only way to tell is to breed the bird with a known bird because the outcomes will be different due to the different inheritance patterns. There have been several threads here on that issue the last few months.

Ok
I questioned this because i have YB Gouldians with WB and they never gived me chicks Australian Yellow. But, where it is normal since we are separeted by 15000 kms and i believe taht mutation only reside in Australia but their i think is a little more dificult to find out, if you have 2 identical birds and one is a normal yellow and the other an Australian Yellow.

This is where we have so much confusion in Australia. Someone who is new to Gouldians, or just to mutation Gouldians. Gets a yellow bird from somewhere and starts breeding. Then another yellow bird from somewhere else. And so, I believe, quite a few of the birds are split between the 2 mutations anyway. I know I am not the only one aware this is not uncommon.
