Appalachian Spring: Long-term Studies at Mountain Lake

For nearly 40 years, Dr. Ellen Ketterson and her research team from Indiana University have been studying juncos in the mountain forests of Virginia. This segment introduces viewers to the junco, the researchers, and the core methods they use to study birds. Set in field, lab, and aviary locations, one landmark study is highlighted in detail: a long-term field experiment investigating the complex effects of the hormone testosterone on behavior, physiology, and evolutionary fitness.
