Sparrows Do the Long Haul Without Sleep
During their 2600-mile migrations from Southern California to Alaska, white-crowned sparrows fly day and night without sleep for days on end. Apparently they don’t have to fly on automatic pilot. Science Now tells about a University of Wisconsin psychiatrist who watched captive sparrows during their migratory period. The birds seemed alert and in no way impaired by the lack of sleep.

Some of us, like truck drivers and students, might get more done if we had bird brains.
