Bird Sturnus vulgaris common in N Eurasia and naturalized in North America from the late 19th century. The black, speckled plumage is glossed with green and purple. Its own call is a bright whistle, but it is a mimic of the songs of other birds. It is about 20 cm/8 in long. Strikingly gregarious in feeding, flight, and roosting, it often becomes a pest in large cities, where it becomes attached to certain buildings as `dormitories', returning each night from omnivorous foraging in the countryside. If disturbed, starlings have been known to lay eggs in the nests of other birds before starting a new nest with their mate elsewhere. More than 100 species of starling, family Sturnidae, are found in the Old World.
