A medium-sized iridescent blue-green glossy starling with a dark ear-patch and contrasting royal blue to violet flanks and belly. Pairs and small groups occupy savanna, where they feed on the ground and in trees on fruit and insects; occasionally up to 300 may gather at fruiting trees. Often the species scavenges from people. It gives a cat-like nasal “squuee-aar” contact call that is distinctive. The similar Lesser Blue-eared Starling differs from Greater Blue-eared Starling by being smaller with a more compact head and finer bill, by having a smaller ear-patch, and by preferring broadleaf woodland. The Cape Starling differs from the “blue-eared” starlings by having greener ear-patches, belly, and flanks.
