Hi finchy85 this gouldian finch is sf yellow back,if you have a look at his colour in the back he is dilute version that can’t produce black in colour and that why you get a grey version which yellow block black and turn into grey,I hope this will help to understand the colour.

Hi VP6,
There is no such thing as a yellow split black headed Gouldian.
A yellow tipped beak/black headed bird is actually a black headed bird with 2 yellow head genes, just as a yellow headed bird is a red headed bird with 2 yellow genes.
A black headed bird split yellow(1yellow gene) will appear black, a red headed bird split yellow(1 yellow gene)will appear red.
To answer your question,
It is the back colour not the head colour that infuences the black on gouldians.
I don't know why this is, maybe the yellow head is not really a yellow but actually an orange ?

Hi VP6,
After a discussion with another forum member I will clarify my answer slightly.
You can get a yellow headed bird which is split for black (technically it is a RH split BH which has 2 yellow genes) the 2 yellow genes act on the dominant red colour creating a yellow head.
In my original answer I was pointing out that a YTB bird is a BH with 2 yellow genes, not a yellow head split for black.

You can get Yellow split to black in males only as black is sex-linked recessive (so no female splits). These will have a red-tipped bill exactly the same as a pure black.
A yellow-billed black is actually a yellow and a black both occurring simultaneously in the same bird. In these, the darker black head colour totally masks any yellow on the head.
