國外文獻資料:
"In other species of parrots, individuals with extensive red suffusion are well known but have not been established as genetically controlled mutations. Many of these individuals are suffering with internal illness, particularly liver disease. However, with time more examples of true colour morphs under genetic control will be developed. "
大意是,此種紅色小鸚並非控制基因而產出種類,而是一種肝臟病變。
