WHITE-BREASTED NUTHATCH
(Sitta carolinensis)
With a length of 6 inches, this resident of the United States, southern Canada and Mexico might readily be mistaken by a casual observer for a small woodpecker. But its call—an oft-repeated “yank”—is very unwoodpecker-like. Also unlike either woodpeckers or creepers, it climbs downward head first as easily as upward, seeming to defy the laws of gravity. “Nuthatch” was suggested by its habit of wedging nuts in crevices of bark so as to break them open by blows from a sharp, strong bill. The white-breast gets its living from the trunks and branches of trees, over which it walks from daylight to dark. Insects and spiders constitute about half of its food. More than half of its vegetable food consists of acorns and other nuts or large seeds. It’s a bird of the wooded suburbs, and will feed at sheltered stations offering suet, sunflower seeds, or nuts.
WHITE-CROWNED SPARROW
(Zonotrichia leucophrys)
From tail-tip to beak, this perky flyer is 7 inches long and looks like the white-throated sparrow, but the latter has a yellow spot beside its eyes. White-crown breeds in the high country of New Mexico, Colorado, Wyoming, Montana, and the Pacific coast; it winters in the southern half of the United States and in northern Mexico.
This beautiful sparrow is numerous in the West, but rather rare elsewhere, so watch for it carefully if you’re in the East, for it is shy and retiring there. But the white-crown is bolder and more conspicuous in the Far West, often frequenting gardens, parks, and yards. Like most sparrows, it is a seed eater by preference—it appears readily at sheltered feeding stations. Insects comprise less than 10 percent of its diet.
