Question

Did you know? Ducks sleep with half their brain active — the other side sleeps. During "sleep" they keep one eye open to watch for predators. In groups the ducks at the edge sleep alert (one eye open), while the ducks inside can sleep fully.

Accepted Answer

Ducks sleep with half their brain active — the other side sleeps. During "sleep" they keep one eye open to watch for predators. In groups the ducks at the edge sleep alert (one eye open), while the ducks inside can sleep fully.

Eenden slapen met half hun hersenen actief — de andere kant slaapt. Ze houden tijdens "slapen" één oog open om roofdieren te zien aankomen. Bij groepen slapen de eenden aan de rand alert (één oog open), terwijl de eenden binnenin volledig kunnen slapen.
