Single Factor Australian Yellowface

All About Australian
Yellowfaces
by Didier Mervilde

The first Australian Yellowface was imported by the German Rolf Christen in 1980. It is a yellowface with a far deeper golden buttercup yellow face and in combination with the darker colours it looks very stunning. In the U.K. it was Jeff Attwood who bred them to the European exhibition standard .

The single factors leave the nest as beautiful yellowfaces, but on moulthing to adults plumage will become mainly green on the breast and flanks. Special for the mutation is that their original colour is retained under the wings. The double factors is the exhibition bird with an outstanding colour on the face .

You can pair them to greys, ino’s, violets and even slates.

For the moment I am pairing them with slates and ino’s. Paired to albino you obtain a nearly yellow bird. In slate you have a lovely contrast between the yellow face and the slate body colour.

Australian yellowface is a partially dominant or co-dominant mutation. This means that it is a recessive allele to blue.
