Pure Light Yellow to pure Light Yellow is the only mating which one need seriously consider when the production of high-class exhibition Light Yellows is the sole objective. Light Yellows/white, Light Yellows/Lutino or Light Yellows bred from Light Greens/yellow, Light Greens/white or any other Green Series are no use for Yellow breeding. These birds cary more green suffusion than do the best Light Yellows, and their youngsters inherit it.

As the Standard indicates, the ideal colour is that which the term "buttercup" aptly describes, and it should be as free from pencilling and green suffusion on the rump and elsewhere as possible. Unfortunately, depth of body colour is often accompanied by heavy pencilling on the wings, whereas the lighter coloured birds are frequently more pure. The Cinnamon Yellow is usually more free from green but lighter in shade. If the cross with the Cinnamon had accomplished onething only, viz., purification, it would have proved a blessing, but, unfortunately, it simul- taneously robbed us of colour depth. Nevertheless, it might be wise to lose something in colour and improve type (for which there is a great need in Light Yellows) by founding a family of Cinnamon Light Yellows. I know a fancier in South Africa who has successfully accomplished this.

Another problem which besets the breeder of Light Yellows is associated with size. The bigger birds are often less deep and bright than the smaller ones, and it would seem that the "Yellow" and "Buff" theory comes into the story here. Be all this as it may, up to the time of the obvious decline in the general quality of Light Yellows, many good show birds were regularly produced by the method adopted by successful breeding of Light Yellows, namely the continuous mating of pure Light Yellows to pure Light Yellows without the introduction of any alien blood whatever; the meticulous selection of the birds of the best type and the best colouring; the ruthless elimination of those faulty in shape or faulty in colouring. Mr. RJ. Watts produced his famous strain-the foundation of the butter cup Light Yellow--by these methods.

Unfortunately, the Light Yellow has declined so much in shape of body and head and in size that to persist with Light Yellow cannot bring about any general improvement. There are not sufficient good birds good birds available for the purpose. Some may ask if crossing with the Dark-eyed Clear Yellows might improve the situation. The answer is no, because the Dark-eyed Clear Yellows are no better shaped, if as good, as the Normal Light Yellows. Certainly they are superior in colour, but it is in type that Light Yellows are inferior to other varieties today.

It is inadvisable ever to mate any Budgerigars with the primary object of producing Dark Yellows for exhibition purposes for the reasons fully explained in Chapter 4. In fact. Dark Yellows cannot serve any useful purpose, either as show or breeding birds.

As indicated in Chapter4, Olive Yellows are now very scarce, and they are often not sought as an out-cross for other colours. I know of no fancier who is actually breeding Olive Yellows with a view of producing specimens in this variety worthy of competing in Any Other Colour classes. If anyone decides to do so, Olive Yellow x Olive Yellow would appear to be the best mating if the birds used are sufficiently good in type.
