The White–crowned Sparrow (Zonotrichia leucophrys) is a common breeding species on the west coast of North America, ranging from southern California to Alaska, although it is restricted to more northerly latitudes in the central and eastern part of the continent (Banks, 1964). the wings and tail. nesting loose flocks form within the breeding habitat. 0000012699 00000 n
