Recognizing the Super Singer and Breeder Mark
Many years ago, I noticed that my highest scoring rollers all had a distinct mark on the right side of their neck. Starting at the neck line just above the shoulders was a base and curving mark that pointed or reached the eye.
Being fairly new to roller breeding at the time, I contacted the now late Jim Naquin, a well known outstanding roller master breeder from California, and ask if my observations were correct. Not being an easy guy to get answers from, I was thrilled when he enthusiastically told me that yes my observation of the curved pointing mark and high scoring was correct but that the mark could be on either side or both. He also agreed that these bird's offspring are consistently the best of the bunch! Now so many years later, I finally just this year have some double marked birds which I think are probably hens.
When I attended the German Meisterschaft Roller Shows in Germany, I was not surprised by the high number top scoring birds which displayed the Super Singer Mark. If was at least 80 or more %!
Breeding quality roller song is a challenge because it is not simply one gene producing a desired note. Most of the genes are not directly expressed but the sound observed is the result of not only having the gene but also the right regulator genes that control its expression.
Song genes are located on the same sex chromosomes with genes for pigmentation. Some traits on top of that, such as Schockel, are recessive and must be inherited from both parents to be sung.

Linda, that mark is also "desireable" in waterslagers.
That grizzle pattern is quite common in the betters singers. I think it shows the common ancestry between rollers and waterslagers?
