Ever wondered how birds pull off those epic migrations without GPS? Turns out, they’ve got a built-in navigation system that’s part Google Maps, part sci-fi. They use landmarks, the sun, stars, and even Earth’s magnetic fields—like a natural compass. Scientists are cracking the code on how this works, which could help protect endangered species by understanding their migration secrets.

Editor’s Note: Bird migration isn’t just impressive—it’s a survival superpower. As habitats shrink and climates shift, knowing how birds navigate helps conservationists protect their routes. Plus, it’s a reminder of nature’s genius—no Wi-Fi required.
