HOW DO BIRDS NEVER GET LOST?
Birds travel thousands of kilometres every year, yet they can find their way with amazing accuracy. They use several natural navigation systems instead of just one.
HOW BIRDS FIND THEIR WAY
* The Sun: During the day, birds use the Sun as a compass and adjust for its movement across the sky.
* The Stars: At night, many migratory birds navigate by the stars, especially around the North Star in the Northern Hemisphere.
* Earth's Magnetic Field: Birds have a built-in “magnetic compass.” Tiny magnetic particles and special cells help them sense the Earth's magnetic field and know which direction to fly.
* Landmarks: Rivers, mountains, coastlines, forests, and even roads help birds recognise familiar routes.
* Sense of Smell: Some birds, such as pigeons and seabirds, use smells carried by the wind to locate their home or nesting places.
* Memory: Birds remember routes they have flown before and can return to the same nesting site year after year.
AMAZING FACT
The Arctic tern travels about 70,000–90,000 km every year, flying from the Arctic to Antarctica and back. Despite this incredible journey, it returns to almost the same breeding place every year.
NATURE'S LESSON: Birds remind us that with the right guidance and memory, even the longest journey can lead us home.
