A species isn't defined by if it can interbreed with other species or not. Horses and donkeys can produce offspring (although they are mule - and there's some discussion about how certain Neanderthal/Sapiens combinations could possibly also be mule, but that's not important). And Darwin's finches (https://en.wikipedia.org/wiki/Darwin%27s_finches https://en.wikipedia.org/wiki/Darwin%27s_finches) are defined as different species, but can technically interbreed.
