The violet-backed starling (Cinnyricinclus leucogaster), also known as the plum-colored starling or amethyst starling, is a relatively small species (17cm) of starling in the family Sturnidae. It is the only member of the genus Cinnyricinclus. This strongly sexually dimorphic species is found widely in the woodlands and savannah forest edges of mainland sub-Saharan Africa. It is rarely seen on the ground, but instead found in trees and other sources away from the ground.
The violet-backed starling is a sexually dimorphic species in which the males possess an iridescent violet back while the females are brown. During breeding, the female will incubate 2-4 eggs (these are pale blue with reddish/brown spots) for 12–14 days. The male will help feed chicks until they fledge after about 21 days.
