European starling (Sturnus vulgaris)

The common starling was first described by Carl Linnaeus in his Systema Naturae in 1758 under its current binomial name. Sturnus and vulgaris are derived from the Latin for "starling" and "common" respectively. The Old English staer, later stare, and the Latin sturnus are both derived from an unknown Indo-European root dating back to the second millennium BC. "Starling" was first recorded in the 11th century, when it referred to the juvenile of the species, but by the 16th century it had already largely supplanted "stare" to refer to birds of all ages. The older name is referenced in William Butler Yeats' poem "The Stare's Nest by My Window".The International Ornithological Congress's preferred English vernacular name is common starling.

The starling family, Sturnidae, is an entirely Old World group apart from introductions elsewhere, with the greatest numbers of species in Southeast Asia and sub-Saharan Africa. The genus Sturnus is polyphyletic and relationships between its members are not fully resolved. The closest relation of the common starling is the spotless starling The non-migratory spotless starling may be descended from a population of ancestral S. vulgaris that survived in an Iberian refugium during an Ice Age retreat, and mitochondrial gene studies suggest that it could be considered a subspecies of the common starling. There is more genetic variation between common starling populations than between the nominate common starling and the spotless starling. Although common starling remains are known from the Middle Pleistocene, part of the problem in resolving relationships in the Sturnidae is the paucity of the fossil record for the family as a whole.
