Behavioral Ecology

I manage Project FeederWatch, a program in which people who feed birds in their backyards send counts of those birds to the Lab. This program has been running for over 30 years and participants have created an enormous dataset of bird population changes through time. I love this program and am proud to be a part of it because it is such a meaningful way for people to contribute to science by doing something they already love. We learn about how birds are doing in the process, in a way that we could never do without the collective efforts of people across North America.
