Scientific name: Mimus polyglottos
Occurring throughout North America south of southern Canada, the Northern Mockingbird is familiar for its tolerance of human activity, its occasional, aggressive attacks on family pets, its wide range of vocalizations, and its habit of singing late into the night during the breeding season. Male Northern Mockingbirds do most of the territory defense, although females participate as well.
Northern Mockingbirds are capable of breeding at one year of age, but more males than females are typically present in adult populations, and young males may not be as competitive as older males in securing a mate. Northern Mockingbirds have been known to live eight years in the wild.
