The stars appear to rotate in the sky, raising the question of how birds can use stars to navigate during migration. Ornithologist Stephen Emlen brought Indigo Buntings to a planetarium, tracking their movements as the simulated night sky changed above them. The buntings oriented themselves using star patterns that appear to rotate the least — especially the North Star, Ursa Major and Cassiopeia. Learn more at BirdNote.org.
