David Bonter

Director, Citizen Science


Citizen Science • Avian Ecology • Foraging Ecology

As director of the Citizen Science program, I oversee projects including Celebrate Urban Birds, NestWatch, and Project FeederWatch.

In addition to leading the Citizen Science program, I’m an avian ecologist focused on mentoring undergraduate research, teaching field courses, and engaging the public in scientific research. Please see my website for more details.
