The definition of "species" doesn't say that members of separate species can't interbreed, just that they don't. There are lots of examples of closely related species of birds, say, where you can cross-breed by artificial insemination and get fertile offspring, but in the wild they don't, either because the two species do not live in the same area or just because their tastes in breeding partners differ.
