The Red-breasted Nuthatch (Sitta canadensis) is native to North America. Its geographical distribution spans from southern Alaska, across Canada, and into the northeastern and western United States. The range extends as far south as the central United States during winter migration.

The species predominantly inhabits coniferous forests, preferring mature and dense stands of spruce, fir, pine, and other evergreens. Typical environmental conditions include cool to cold climates, with a preference for areas that maintain significant tree cover for nesting and foraging. During the non-breeding season, the Red-breasted Nuthatch may also occupy mixed or deciduous forests, especially in regions outside its usual breeding range.

The ecological niche of the Red-breasted Nuthatch involves foraging on tree barks for insects and seeds. It plays a crucial role in the ecosystem by helping control insect populations and contributing to seed dispersal. The species is adept at climbing tree trunks and branches, often moving in a headfirst downward motion, which is a distinctive foraging behavior. Variations in its habitat usage are noted during migration, when it may adapt to diverse forest types.
