UNC biologist Allen Hurlbert has built a comprehensive online database of North American bird diets. An article was published Oct. 4 in the journal Scientific Data that describes how the database was created.

Scientists analyzed more than 31 million iNaturalist records in a new study to find out who most often uses the popular nature app and what types of observations they submit. The most observed species? The monarch butterfly.

Every other year, professors Allen Hurlbert and Keith Sockman lead an avian biology course that explores the physiology, anatomy, evolution, and behavior of birds.
