The White-crowned Sparrow (Zonotrichia leucophrys) is a medium-sized sparrow native to North America.
Adults are 18 cm long and have black and white stripes on their head, a grey face, brown streaked upper parts and a long tail. The wings are brown with bars and the underparts are grey. Their bill is pink or yellow.
Their breeding habitat is brushy areas across northern Canada and the western United States. They nest either low in bushes or on the ground under shrubs and lay 3-5 brown-marked grey or greenish-blue eggs.
White-crowned Sparrow is a very rare vagrant to western Europe. One was present in County Cork, Ireland in May 2003. Another was found in Norfolk, England in January 2008. A young sparrow was also observed in Ona, Norway in October 2009. A young bird was seen in Surrey, England in May 2010.
The White-crowned Sparrow is known for its natural alertness mechanism, which allows it to stay awake for up to two weeks during migration.
