1. Arctic Tern
The Arctic Tern is a true champion of long-distance travel, boasting the longest annual migration of any animal. Each year, these remarkable birds journey from the icy Arctic to the Antarctic and back—an astounding round trip of over 40,000 miles. Experts believe Arctic Terns rely on a combination of the sun’s position, Earth’s magnetic field, and even their sense of smell to guide them with astonishing precision. Source: National Geographic
