The northern mockingbird (Mimus polyglottos) is the only mockingbird commonly found in North America. This bird is mainly a permanent resident, but northern birds may move south during harsh weather. This species has rarely been observed in Europe.This species was first described by Linnaeus in his Systema Naturæ in 1758 as Turdus polyglottos. The northern mockingbird is known for its mimicking ability, as reflected by the meaning of its scientific name, 'many-tongued mimic.' The northern mockingbird has gray to brown upper feathers and a paler belly. Its tail and wings have white patches which are visible in flight.
