It takes a village: With camera and determination, Riehl studies communal nesting in birds

Christina Riehl, a Princeton University assistant professor of ecology and evolutionary biology, was, as a Princeton graduate student, the first to study and document the extraordinary breeding and nesting behavior of the greater ani bird species. This fall, Riehl returned to Princeton to explore the reproductive costs and benefits of group nesting, and, in the process, inspire her students to investigate animal behavior at a deeper level.
