| Zonotrichia leucophrys (Forster, 1772) |
The White-crowned Sparrow (Zonotrichia leucophrys) is a medium-sized sparrow.
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. They are similar in appearance to the White-throated Sparrow but do not have the white throat markings.
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.
There are five currently recognized subspecies of white-crowned sparrow (pugetensis, gambelii, nuttalli, oriantha, and leucophrys), varying in migratory behaviour and breeding habitat. The Nuttall's subspecies are permanent residents in California, while the Gambel's subspecies may migra as far as the Arctic circle during the summer breeding season. Northern birds migrate to the southern United States. White-crowned Sparrow is a very rare vagrant to western Europe.
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.
The call of the White-crowned Sparrow has many dialects, but the pugetensis subspecies sounds similar to "You can't come and come and catch me!"
