This chapter presents the biogeography of the House Finches, which has an extensive range across North America. House Finches were accidentally established by people on the east coast in the mid-20th century and had spread throughout the eastern U.S. and Canada by the late 20th century. Across their native range in western North America, taxonomists recognize eighteen subspecies of House Finches. Across their range, male House Finches vary in the size of their red throat/breast patch as well as in the brightness of red coloration.
