This a quote from ABK A Guide to Gouldian Finches:brooksy wrote:It is seeming very hard to source pure normals especially Zebras!! Tintola what you said about yellow tips on the black heads, Are they rare? are they usually normally red?
A red headed gouldian has a red tipped beak
A black headed gouldian can have a red tipped beak or a yellow tipped beak
A yellow headed has a yellow tipped beak
The normal black headed gouldian has a red tipped beak, however when a gouldian inherits both the characteristics for black and yellow headedness, the black will mask the yellow. That is to say it is a yellow headed bird with a black head and not simply a black headed split to yellow headed. Therefore because it is a yellow headed bird it has a yellow tipped beak. A black headed gouldian split to yellow will have a red tipped beak.
Sheesh

At the beginning of the season I try to set up 3 to 4 pairs of each head colour and have not had any infertility problems so far. I'm not game to introduce new blood as I don't know what I'm getting. I've seen too many friends end up with white fronteds. I've also had similar issues with non mutation Zebs and now have a colony that only produce wild strain normals that are somewhat smaller than mutation Zebs.
