The red wolf (Canis lupus rufus, formerly Canis rufus) is a North American canid that once roamed throughout the Southeastern United States. Based on fossil and archaeological evidence, the original red wolf range extended throughout the southeast, from the Atlantic and Gulf Coasts, north to the Ohio River Valley and central Pennsylvania, and west to central Texas and southeastern Missouri. Historical habitats included forests, swamps, and coastal prairies, where it was an apex predator. The red wolf is morphologically midway between grey wolves and coyotes, and recent genetic research indicates it may actually be a hybrid species. The red wolf was thought to be extinct in the wild by 1980. 1987 saw a reintroduction in northeastern North Carolina through a captive breeding program and the animals are considered to be successfully breeding in the wild.
