White-crowned Sparrow (Zonotrichia leucophrys).
Taken at Campbell River, Vancouver Island, BC.
The white-crowned sparrow is known for its unihemispheric slow-wave sleep, which allows it to stay half-awake for up to two weeks during migration. This effect has been studied for possible human alertness applications in shift work and truck driving. Amazing! Nature and the world around us have much to teach us..
