This particular bird represents a color mutation within the Quaker parrot species ( Myiopsitta monachus). Specifically, it refers to individuals exhibiting both a blue color variant (lacking the yellow psittacine pigments) and the opaline mutation (which alters the distribution of melanin, creating a softer, more pastel appearance). A typical example would be a Quaker parrot with predominantly blue plumage, accented by areas where the blue is less intense, appearing almost grey or silver due to the opaline effect.
The existence of this color combination is important to aviculture for several reasons. It enhances the aesthetic appeal of these birds, increasing their desirability as pets. Furthermore, the study of how these mutations interact genetically contributes to a broader understanding of avian genetics and color inheritance. Historically, such color variations have been selectively bred, leading to a wider range of appearances within domesticated bird populations. This drives interest in conservation and ethical breeding practices.
