Few purebred Eurasian wild boars are left today, but they have hybridized with feral domestic hogs and continue to spread. All are interchangeably called wild or feral hogs, pigs or boars; in this context, “boar” can refer to a male or female. (Technically, “feral” refers to animals that can be traced back to escaped domestic pigs, while the more all-encompassing “wild” refers to any non-domestic animals.) Escaped domestic hogs adapt to the wild in just months, and within a couple of generations they transform into scary-looking beasts as mean as can be.
