Episode 9: What mockingbirds can tell us about environmental lead contamination

Dr. Kelly Diehl talks with Dr. Jordan Karubian, Associate Professor at Tulane University’s Department of Ecology and Evolutionary Biology, about his latest study, which found that mockingbirds exposed to sub-lethal levels of lead in urban areas display heightened aggression. He says the findings highlight the possibility that sub-lethal lead exposure may be common among other wildlife living in urban areas and more work is needed to better understand its full effects.
