Do red wolves hybridize with coyotes?
Red wolves, gray wolves, domestic dogs and coyotes are capable of interbreeding and producing fertile offspring. Social structures and territoriality usually prevent such interbreeding. By 1960, widespread persecution of predators and the destruction of habitat had caused a decline in red wolf numbers and the coyote began to migrate into the southeast. As a result, some of the remaining red wolves were unable to find mates of their own species and they began to hybridize with the more abundant coyote. Hybridization is usually accepted as the final factor that resulted in the near extinction of the red wolf. Given a choice, red wolves prefer red wolves as mates.
