Tiaris wrote: 10 Nov 2017, 11:28 The white-breasted gene does usually combine to result in a yellow back on single factor birds and the degree of this "dilution" is also very variable between individuals.
I don't understand why you would think there would be no yellow on the belly - we are not talking about a blue mutation as well. WB & pastel both retain a yellow belly.
The grey on the throat confirms Euro yellowback/pastel rather than the other known diluted and yellow mutations at play IMO and the breast colour is self-evident.

Gary, i think you are confused with pastel in blues. This is a pastel yellow with a white breast with the WB contributing to the overall diluting of the body. Again i agree with Tiaris. Craig
