Dilute/Yellow Pacifics, Color Mutation Nomenclature

Was just wondering why the American yellows were renamed dilute? I can't believe how much has change with these birds in the last few years.


No problem Matt. The name was changed to dilute years ago – at least 5 years ago or probably longer. The reason? The bird isn’t yellow. Genetically, it is a dilute not a yellow and since the probably is that eventually we will have a true yellow, the name was changed. One only has to look at “American white” also not a genetic white and the name was changed to the correct term of dilute-blue. We now actually have a dark-eyed white so it was prudent to get the name corrected before the white was produced.

A lot of people have the misconception that just because there is a new color mutation in a bird like a parrotlet that it can be named whatever people want to name it. Not true. There are nomenclature standards that are accepted by the world-wide scientific community for the genetics of color mutations in birds. These are based on scientific and biological interpretations and follow the guidelines established for other birds. Hence a blue ringneck is the same genetically as a blue parrotlet as a blue Amazon as a blue budgie and so on.

Hope this helps and have a great weekend!
