The Great Crested Flycatcher (Myiarchus crinitus) is native to North America, particularly throughout the eastern and central United States, and parts of southern Canada. Its range extends from southeastern Canada through the eastern United States, reaching into Mexico and parts of Central America during migration and winter.

Myiarchus crinitus typically inhabits deciduous and mixed woodlands, forest edges, and open areas with scattered trees. This species prefers warm temperate climates during the breeding season in North America, and it seeks out similar but warmer climates in Central America during the non-breeding season.

As an arboreal species, it occupies a niche that includes hunting for insects and occasionally consuming fruits. Its role in the ecosystem includes controlling insect populations and aiding in seed dispersal. The Great Crested Flycatcher is an adaptable species, able to inhabit a range of open wooded environments.
