Red Wolves:

The red wolf (Canis rufus, formerly Canis lupus 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 Indiana and 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 a 2011 genetic study indicated that it may be a hybrid species between grey wolves and coyotes. Re-analysis of this study coupled with a broader contextual analysis including behavioral, morphological and additional genetic information led to arguments that the red wolf is an independent species but has suffered from significant introgression of coyote genes likely due to decimation of red wolf packs with fragmentation of their social structure from hunting. The most recent comprehensive review (in October 2012) of the genetics studies concluded that the red wolf, eastern wolf, and gray wolf were three distinct 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. (from wikipedia)

The red wolf is generally a crepuscular species, most active at dawn and dusk. It lives in discrete packs, which have an exclusive territory within their home range. A pack typically contains a breeding pair (who mate for life) and their offspring, although larger packs have been recorded. The breeding season occurs between January and March, and dens are located amongst dense vegetation, in deep burrows between fields or in canal banks, or in the hollows of large trees. Litters contain an average of three to six pups, but may range up to eight pups. The breeding pair both rear the young with help from the other young members of the pack. Offspring typically disperse from their natal pack between 15 to 20 months old. (from Arkive)
