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!). BirdCast, a tool that can forecast the peak migration nights of the season, is helping these programs make a greater impact. Tenijah speaks with Julia Wang, project leader at BirdCast and the Lights Out Texas campaign at the Cornell Lab of Ornithology.Lights Out Program | BirdCastLights Out | National Audubon SocietyResearch: Study Names Top Cities Emitting Light that Endangers Migratory BirdsFLAP CanadaLights Out for Birds | Houston Audubon More info and transcript at BirdNote.org. Want more BirdNote?
