YELLOW-FACE Type I and Type II.
These birds really belong to the Blue series because their ground colour is white but have varying areas of yellow suffusion. It is the Type I birds that are most desirable for exhibition purposes as their yellow suffusions are more or less confined to specific areas, namely, mask (face), tail and wing butts. With the Type II birds the whole body has a strong yellow wash giving the birds a sea green colouring. They can always be identified from Greens as the colour of the feathers on the underside of the wing butts is always a blue shade. Both kinds of the Yellow-faced character can be carried in split form by Green series birds but they cannot be split for both Yellow-faced and Blue at the same time.

Whereas the Yellow-face Type II birds follow the usual pattern of inheritance the Type I have a different manner of reproduction. When two single character Yellow-face Blue Type II are mated together the theoretical expectation is as expected 50% single character, 25% double character and 25% Normal Blue. In actual fact that is the result but with a difference as the double character Yellow-face Blue Type II birds do not show any yellow on their plumage and look exactly the same as ordinary Blues. When one of these special double character Yellow-face birds is mated to a Normal blue all their young are Yellow-face Blues with a single character. It took breeders quite some time to fathom out this unusual way of passing on the character; therefore with the Yellow-face Blue Type I mutation it is only the single character birds that actually show the yellow markings on their plumage.

All that I have written about the breeding of Whitewings applies to production of Yellow-wings, with the exception that here one can, if so wishing, dip straight into the Green. An outstanding Light Green can be mated to a Yellow-Green. This should produce valuable Light Greens/Yellow-wing, which when put to Yellow-wings will breed Yellow-wings. These can be paired to other Yellow- wings or to Whitewings, when Yellow-wings/Whitewing will be the outcome. These birds can, in turn, be mated to Whitewing. And so there may come into being both Yellow-wings and Whitewings showing the beneficial effect of the out-cross to that outstanding Light Green.

Incidentally, and as I have already indicated, just as we mate our Normal Skyblue to our Light Greens/blue, so it is quite permissible and often wise to provide Whitewing mates for Yellow-wings, and in due course found a strain of Yellow-wings and Whitewings all of one family. As with Whitewings so with Yellow-wing Greens, generally speaking there has not been that improvement which was once expected, and I am certain that only by judicious out-crossing to the old Normal varieties will progress be made.
