Different species can also interbreed in the natural world. E.g. wolves and coyotes regularly produce fertile offspring (most often via dogs since wolves and coyotes mate at different times), grizzle bear and polar bear likewise (will happen more often as polar bears migrate south from the melting ice caps). Even humans interbred in the history of our species with different species of humans (most notably Neanderthals). I think the both terms are correct, but I like races better because species also includes every lifeform which can never be characters, like ravens, wargs or even tobacco plants.
