BirdNote® Swainson’s Thrush “Micro Napper”
When this nighttime traveller wants to take a break from migrating, it sleeps for moments at a time, with one eye closed and the other open to watch for predators.
The Swainson’s Thrush is something of a night owl – it stays up all night and travels long distances. And when it needs some zzzzzzzz’s, the bird takes daytime mini-naps, sleeping with one eye open. Mary McCann reports.
