    Birds that are half-asleep-with one brain hemisphere (半球) alert and the other

sleeping-control which side of the brain remains awake, according to a new study of

sleeping ducks.

    Earlier studies have documented half-brain sleep in a wide range of birds. The brain

hemispheres take turns sinking into the sleep stage characterized by slow brain waves.

The eye controlled by the sleeping hemisphere keeps shut, while the wakeful hemisphere's

eye stays open and alert. Birds also can sleep with both hemispheres resting at once.

    Decades of studies of bird groups led researchers to predict extra alertness in the

end-of-the-row sleepers which tend to be attacked more easily. Sure enough, the end birds

tended to watch carefully on the side away from their companions. Ducks in the inner spots

showed no preference for gaze direction.

    Also, birds napping at the end of the line depend on single-hemisphere sleep, rather

than total relaxation, more often than inner ducks did. Turning 16 birds through the

positions in a four-duck row, the researchers found that compared with 12 percent for

birds in internal spots, outer birds half-asleep during some 32 percent of napping time.

    "We believe this is the first evidence for an animal behaviorally controlling sleep

and wakefulness at the same time in different regions of the brain," the researchers say.

    The results provide the best evidence for a long-standing assumption that single-

hemisphere sleep evolved as creatures scanned for enemies. The preference for opening an

eye on the lookout side could be widespread, he predicts. He's seen it in a pair of birds

napping side-by-side in the zoo and in a single pet bird sleeping by a mirror. The mirror

-side eye closed as if the reflection were a companion and the other eye stayed open.

    Useful as half-sleeping might be, it's only been found in birds and such water animals

as dolphins, whales, and seals. Perhaps keeping one side of the brain awake allows a

sleeping animal to surface occasionally to avoid drowning.

    Studies of birds may offer unique insights into sleep. Jerome M. Siegel of the UCLA

says he wonders if birds' half-brain sleep "is just the tip of the iceberg." He

supposes that more examples may turn up when we take a closer look at other species.
