🌎 Every year, the Arctic tern completes the longest migration on the planet — flying up to 70,000 km from the Arctic to Antarctica and back 🐦❄️☀️ It nests in Canada, Greenland, and Iceland, then travels along the coasts of Europe and Africa, crosses the equator, and reaches the icy shores of Antarctica — all in search of endless summer. And it’s not alone. The bar-tailed godwit flies 12,000 km non-stop from Alaska to New Zealand over the Pacific Ocean — spending nine days in the air without stopping for food, water, or rest 🌊🕊️ What’s their secret? 🪶 Birds have a built-in GPS — they navigate using the stars, the Earth’s magnetic field, and even smells. These incredible routes are remembered for life and passed on to chicks, who somehow know the path from their very first flight. Bird migrations are like invisible highways in the sky — traveled by billions of birds every spring and fall ✨
