The Complex Courtship of Sparrows and Beyond

It wouldn't be Pride at Tangents if we weren't getting into some science! We're joined by Owen Ever and Laine Kaplan-Levenson, the hosts of a new show from news outlet Canadaland called "Field Guide to Gay Animals." Our conversation ranged far and wide across a myriad of ways queerness is expressed in the animal world and the challenges and joys of studying it.
