Series:Smithsonian Science How webcasts, which are designed to connect natural history science and research to upper-elementary and middle-school students.
This video features Dr. Helen James, an ornithologist at the National Museum of Natural History. Have you ever considered how a species as abundant as the passenger pigeon (Ectopistes migratorius) could have gone extinct? Analyze their disappearance and consider what factors make birds vulnerable to extinction. Follow Helen into Hawaiian lava tubes to look for prehistoric evidence of bird life on the islands. See which bird species survived and which did not after humans arrived on the scene. Use modern tools and technologies to interpret bird extinctions.
