Animal Navigation: An Enduring Mystery

Author
Walcott, Charles
Abstract
Many animals move thousands of miles over the surface of the earth. Monarch butterflies return to a small place in Mexico to overwinter, Arctic Terns fly some 24,000 miles per year and salmon return to the gravel beds in the streams where they themselves were hatched. Despite years of research, we still don’t know exactly what cues animals use to perform these feats!
