4. Monarch Butterfly
The monarch butterfly undertakes one of nature’s most breathtaking migrations, fluttering up to 3,000 miles from North America to the forests of central Mexico. Despite their fragile appearance, these butterflies are skilled navigators. Monarchs use a sophisticated combination of a sun compass and Earth’s magnetic cues to stay on course across continents. This innate ability allows generation after generation to find the same overwintering sites year after year. Source: National Wildlife Federation
