University of Minnesota researchers set up hundreds of cameras to cover more than 2,500 square kilometers throughout Africa’s Serengeti ecosystem initially to study lions. Now the researchers are looking to expand their knowledge via the Snapshot Serengeti citizen science project to better understand how competing species coexist in a shared environment.

Researchers Ali Swanson and Margaret Kosmala, working with Craig Packer, professor of ecology, evolution and behavior, have developed a site to enlist volunteers to identify millions of “camera trap” photos taken to study animal behavior in the Serengeti.

Citizen scientists view sequences of two or three photos and identify all the different animals that appear in the photos.
