About the Spotless Starling

The spotless starling (Sturnus unicolor) is a passerine bird in the starling family, Sturnidae. It is closely related to the common starling (S. vulgaris), but has a much more restricted range, confined to the Iberian Peninsula, Northwest Africa, southernmost France, and the islands of Sicily, Corsica and Sardinia. It is largely non-migratory.

Subsequent to the recent split of the genus Sturnus, this species and the common starling are the only species retained in the genus. Hybrids with the common starling are found occasionally where the breeding ranges overlap in southwestern France and northeastern Spain.
