In this exclusive behind-the-scenes podcast, meet three researchers featured in “What Females Want and Males Will Do” who are looking for answers to some burning questions about sexual selection. Chadden Hunter spends time with a group of geladas, close relatives of baboons. Gail Patricelli camps out with sage grouses in the midst of courtship. Rebecca Safran hangs out on the farm with barn swallows. Cutting-edge technology and plain old hard work both play a role in the lives of these trailblazing scientists. Part of the 26th season of the Peabody and Emmy award-winning series produced by Thirteen/WNET New York for PBS, “What Females Want and Males Will Do” premieres over two Sundays, April 6 and 13, at 8 p.m. (check local listings).
