How do birds sleep while flying thousands of kilometers during migration? Meet the frigate bird — a remarkable species that can literally sleep on the wing! In this video, we explore the fascinating science behind how migratory birds manage sleep during their epic journeys.
Using EEG studies, researchers discovered that frigate birds use uni-hemispheric slow-wave sleep — resting one half of their brain while keeping the other alert. Learn about REM vs NREM sleep in birds, why frigates spend less than 3% of flight time sleeping, and how different species like the Alpine Swift and garden warbler have their own unique sleep strategies.
