\"White-crowned Sparrow,\" Wikipedia, the free encyclopedia. The White-crowned Sparrow (Zonotrichia leucophrys) is a medium-sized sparrow native to North America.These birds forage on the ground or in low vegetation, but sometimes make short flights to catch flying insects. They mainly eat seeds, other plant parts and insects. In winter, they often forage in flocks. White-crowned Sparrows nest either low in bushes or on the ground under shrubs and lay 3–5 brown-marked grey or greenish-blue eggs. The White-crowned Sparrow is known for its natural alertness mechanism, which allows it to stay awake for up to two weeks during migration.This effect has been studied for possible human applications, such as shift-work drowsiness or truck driving.
