European Starling Sturnus vulgaris Often regarded as a pest, the Starling wins our grudging admiration for its adaptability, toughness, and seeming intelligence. Brought to North America in 1890, it has spread to occupy most of the continent, and is now abundant in many areas. Sociable at most seasons, Starlings may gather in immense flocks in fall and winter. When the flocks break up for the breeding season, males reveal a skill for mimicry, interrupting their wheezing and sputtering songs with perfect imitations of other birds. https://www.audubon.org/field-guide/bird/european-starling
