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.
Taxonomy and systematics
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. Confusion with the common starling is particularly easy during the winter, when common starlings are abundant throughout the spotless starling's range, but also in summer where their breeding ranges overlap in northeastern Spain and the far southwest of France. The population has grown in recent decades with a northward expansion in range, spreading to the whole of Spain (previously absent from the northeast) between 1950 and 1980, and colonising locally along the southern coast of mainland France since 1983.
