Baeolophus bicolor, commonly known as the Tufted Titmouse, is native to the eastern United States and parts of southern Canada. It is primarily found across states spanning from the southern parts of Maine and Minnesota to Texas and Florida, extending west to Nebraska and into parts of southern Ontario, Canada.

The Tufted Titmouse predominantly inhabits deciduous and mixed wood forests, often found in oak and pine woodlands. It also adapts well to suburban areas and city parks, provided these areas contain sufficient tree cover. The climate in its native range varies from temperate in the north to subtropical in the southern parts of its distribution.

The Tufted Titmouse plays a crucial role in its ecosystem as both a predator and a prey species. It feeds on a variety of insects and seeds, contributing to pest control and seed dispersal. Its typical diet includes caterpillars, beetles, spiders, and a variety of seeds and nuts, which it often stores for later consumption. As a prey species, it is hunted by birds of prey and other carnivores.
