On this episode I talk with Dr. Geoffrey Hill, professor at Auburn University, about his birding as well as his research. We spend bit of time talking about his theory on speciation, involving compatability of mitochondrial and nuclear DNA.  It is pretty interesting, and I expect you will  find it informative and enjoyable.

This is his birding website:  https://www.ornithologistsblog.com/
I found this article about Dr. Hill's research and speciation theory very informative:  https://aeon.co/essays/why-do-the-most-flamboyant-males-have-the-evolutionary-edge
Thanks for listening. 
Good birding. Good day!
