Meet evolutionary biologist Danielle Whittaker in this video profile from NOVA’s “The Secret Life of Scientists & Engineers.” Danielle didn’t believe it when she was told that birds couldn’t smell. So, she decided to test it for herself. Danielle now studies what birds can smell and the information that the smells indicate. When she’s not proving people wrong, she’s at the rink working as a roller derby referee known as the “Chunk Rock Girl.” This resource is part of the NOVA: Secret Life of Scientists & Engineers Collection.
