The Eagle That Never Crossed the Sea

For 20 years, scientists tracked a steppe eagle with a Russian GPS, following its incredible journey across deserts, plains, and mountains. Yet, despite covering thousands of kilometers, the eagle never once crossed the sea.

Instead, it traced vast circles on solid ground, always avoiding water. Why? The answer lies in the physics of flight. Eagles rely on thermal currents that rise from the earth to keep them soaring. Over the sea, these currents are scarce — and instinct told her that the risk wasn’t worth it.
Her path was more than a habit; it was proof of an extraordinary evolutionary adaptation — wisdom written in wings.
