Mimus polyglottos, commonly known as the Northern Mockingbird, is native to North America. Its geographical distribution extends across the United States, southern Canada, the Bahamas, Mexico, and parts of Central America. The species is also present in the Caribbean, with established populations on many islands.

The Northern Mockingbird typically inhabits a variety of open and semi-open areas. These include urban and suburban regions, parks, gardens, farmlands, and forest edges. The species is adaptable and can thrive in both arid and humid conditions, depending on the area, with a preference for areas that provide ample perches for singing and abundant food sources.

Mimus polyglottos occupies the ecological niche of an omnivorous bird feeding on insects, fruits, and seeds. It is known for its vocal mimicry and plays a role in seed dispersal in its habitat. The species is a proficient aerial forager and is often seen defending its territory aggressively from other birds and animals.
