Oct 2013: Tim Birkhead, barn swallows, and coal tits who hide seeds

In October's BEEPcast Tim Birkhead tells me what ignited his interest in ornithology and sexual selection. I explore why male barn swallows don't act their age when courting females. In the third of my interviews from the Behavior 2013 conference, I speak to Tom Smulders of Newcastle University who explains what Coal tits do with unpalatable seeds.
