Continuing the journey begun in “Diversification I” and “Diversification II,” this segment opens with researchers hitching a ride with the Mexican Navy to visit a breathtakingly beautiful but critically endangered island habitat. Led by Drs. Borja Mila and Ellen Ketterson, the team sets out to collect some of the first modern data and genetic samples from the juncos found on the remote island, with the goal of learning the origins and evolutionary history of this mysterious Junco. What they find could have important implications for the future of this fascinating but imperiled population of juncos.
