Dr. Julie Hagelin’s research has shown that in addition to their senses of sight and sound, some birds also use a sense of smell to communicate with others and to attract mates. She explains how studies of Crested Auklets at the Aquarium of the Pacific and at a breeding site in western Alaska have led her to say: “The bird nose knows”. Dr Hagelin is an assistant professor at Swarthmore College where she teaches classes in animal behavior, behavioral ecology, and general biology.
