The Gouldian finch are small, brightly colored birds with green backs, yellow bellies, and purple breasts with a light blue uppertail and a cream undertail. Sometimes called lady gouldians, their facial color can vary, but black is the most common. Gouldian finch chicks are equipped with blue phosphorescent beads along their mouths, making it easy for the parents to feed them in the darkness of the nest cavity.
