A few days ago, I watched The Wild Parrots of Telegraph Hill, a documentary about wild parrots in San Francisco. There are two different species of parrots that never come into contact with one another in the wild because they live in different parts of South America. However, these two nonnative species interbed in San Francisco, producing a hybrid species that is totally unique. My friend and I had an argument over whether this new parrot species is native or nonative to San Francisco. Is there an answer to this or is it just a matter of semantics?
