Iris Glossy-starling
Encyclopedia
The Iris Glossy-starling, Coccycolius iris, is also known as the Emerald Starling. It is a small starling
with a metallic green crown, upper body, wings and tail. The ear-coverts and underparts are metallic purple. Both sexes are similar. Its placement in a monotypic
genus
Coccycolius is disputed; some unite it with many other glossy-starlings in Lamprotornis

Starling
Starlings are small to medium-sized passerine birds in the family Sturnidae. The name "Sturnidae" comes from the Latin word for starling, sturnus. Many Asian species, particularly the larger ones, are called mynas, and many African species are known as glossy starlings because of their iridescent...
