David Bonter

Co-Director, Center for Engagement in Science and Nature


Citizen Science • Avian Ecology • Foraging Ecology

As co-director of the Center for Engagement in Science and Nature, I oversee projects including NestWatch, Project FeederWatch, and Nest Quest Go.

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