11 Animals With Mind-Blowing Navigation Skills We Barely Understand

4. Arctic Terns: The Long-Distance Champions

Arctic terns are renowned for their extraordinary migratory journey, traveling from their breeding grounds in the Arctic to the Antarctic and back each year. This epic round trip, covering over 44,000 miles, is the longest migration of any animal on the planet. The terns' navigation skills are a marvel of evolutionary adaptation, allowing them to exploit the perpetual daylight of polar summers and optimize their energy use. Researchers believe that Arctic terns use a combination of celestial navigation, geomagnetic cues, and environmental landmarks to guide their journey. The endurance and navigational precision of these birds highlight the incredible feats of migration that occur in the avian world, offering a window into the evolutionary pressures that shape long-distance travel.
