Cinnamon Green Cheeked Conure

Inheritance: Sex-linked recessive (Z-linked)

The cinnamon mutation reduces eumelanin synthesis, converting black/dark melanin to a warmer phaeomelanin-like brown. This shifts the overall body color from green to a warm, brownish-olive green. The grey chest barring becomes tan/beige, the red belly is typically brighter, and the eyes appear red at hatch, maturing to a dark plum-red rather than the dark brown/black of wild-type. Feather shafts are also lightened.

Because it is sex-linked, females only need one copy to express the trait; males need two. This means that a male can carry this trait hidden.
