It is definitely a mixture of both. I took an animal behavior class and learned that song birds actually develop their ability to sing through nurture, not nature. They did several stages and a control and at different points they would take the fledgeling away from its parents. They found that the little ones that were never around adults singing were never able to sing at all, and the ones taken away after a couple weeks could sing but very poorly or they could only do very small phrases correctly. It was quite interesting so I thought I’d share. I don’t remember the name of the research and my textbook is in storage.
