The Vesper Sparrow’s sweet song can be heard throughout varied habitats with bare ground across North America—even cornfields, which are shunned by many other species. Audubon's climate model projects a 73 percent loss of current summer range, with significant northward pushes in both summer and winter ranges. The species’ migratory nature and ability to quickly colonize new areas (such as after forest fires) may help the species realize potential winter gain in a changing world.
