Constant Wonder presents a feed swap with an episode from Bring Birds Back, a podcast about the joy of birds and the ways that humans can help them through simple, everyday actions. In this episode, host Tenijah Hamilton explains that migratory birds use starlight to find their way on their long journeys—which makes light pollution a serious threat. Drawn off course by bright, artificial lighting, birds can wind up fatally colliding with windows or wasting precious time and energy that they need to survive. “Lights Out” programs get cities and their residents to turn off nonessential lighting during migration seasons which can help make their journeys a little easier (and save energy!).

Guest: Bring Birds Back host Tenijah Hamilton speaks with Julia Wang, project leader at BirdCast and the Lights Out Texas campaign at the Cornell Lab of Ornithology
