According to this web site, even though the two species look very similar,
they actually are not as closely related as the similarity suggests. It


That site points to research indicating they can breed and produce
fertile offspring. Sounds like a single species to me. (All other
"scientific" reasons for declaring a new species are, IMO, grounded
only in the scientist's desire for recognition and/or career
advancement ;-)


I'm up in the air about that. For me, it's more complicated than that.
Some different species can be bred and produce fertile offspring but it
can only be done in the lab. That seems like different species to me.
Some different species can breed and produce fertile offspring on their
own but don't in the wild because of different behavioral patterns.
These too seem like different species to me.
