Way et al. (2010) define a “coywolf” population in the northeastern United States and eastern Canada that originated through hybridization between Canis lycaon (Eastern Wolf) and Canis latrans (Coyote), but they maintain that it is now genetically uniform and only minimally influenced by either parental species. An alternative interpretation of available data is that this northeastern Coyote population is genetically diverse, substantially more Coyote than Eastern Wolf in its genetic composition, and part of a larger population of Coyotes that interbreeds with a hybrid Coyote/Eastern Wolf population in southern Ontario and western Coyotes in western New York and Pennsylvania.
