Budgerigar Color Genetics — Understanding Color Variety & Breeding

Budgerigars possess the most diverse color variation among pet birds, with well-studied genetic mechanisms enabling planned breeding for specific colors.

Base Color Series

Green series (wild type): Yellow base + blue structural color = green. Blue series: Recessive mutation lacking yellow psittacin pigment, expressing only blue structural color.

Major Color Mutations

Yellow-face (yellow on blue series faces), Lutino (no melanin — yellow body, red eyes), Albino (blue series + lutino = white body, red eyes), Pied (partial melanin absence), Spangle (co-dominant feather edge pattern change).

Sex-Linked Inheritance

Some mutations (Lutino, Cinnamon) are Z-linked recessive. In birds (ZW sex chromosomes), females express Z-linked recessive traits with just one copy.
