Henslow's sparrows are native to North America. They migrate between winter and summer ranges in the southeastern United States and southeastern Canada. Most begin their northern migration to breeding grounds in early March from the wintering grounds in the mid-Atlantic and Gulf coast states around Florida and Texas and reach the northern limits of their range in New England, southern Ontario, and eastern South Dakota by mid-May. They are rarely seen during their return trip to the south during fall migration (July to late October). Prior to European settlement, Henslow's sparrows are suspected to have lived and bred primarily in prairie habitats. The total global breeding range is approximately 1,100,000 km2. Henslow's sparrows have adapted to live and breed in secondary grassland habitats such as hayfields and pastures due to the loss of native prairie (largely to agriculture). The loss of native habitat and availability of these secondary habitats has caused the species range to expand north and to the east over time.
