New World Sparrows
Spizella passerina
The Chipping Sparrow is a widespread and familiar New World sparrow, often found in human-altered landscapes. This small, slender bird is recognized by its distinctive rusty cap during breeding season. Its adaptability has allowed it to thrive across much of North America.
Typical adult measurements.
Individuals and populations vary.
01 / The telltale details
Start with shape and behavior. Then look for the smaller details.
Bright rusty (chestnut) cap, prominent white eyebrow, and a black line through the eye. Underparts are clean gray.
Cap is a subdued reddish-brown, often streaked, with less contrast in facial markings. Underparts are buff-brown.
Heavily streaked brown crown and underparts, with a dark eye-line. Lacks the distinct rusty cap of adults.
A slender, fairly long-tailed sparrow with a relatively small, conical bill.
02 / A place in the world
Chipping Sparrows inhabit a variety of open woodlands, forest edges, and areas with scattered trees and grassy clearings. They are also common in suburban parks, gardens, orchards, and farmlands, adapting well to human-modified environments.
This species breeds across most of North America, from Alaska and central Canada south through the United States and into Mexico and northern Central America. Its wintering range extends across the southern United States and Mexico to northern Nicaragua.
Northern populations of Chipping Sparrows are long-distance migrants, moving south to the southern United States and Mexico for winter. Central American populations tend to be sedentary. Migration to northern breeding grounds typically occurs in April-May.
03 / Listen a little closer
The song is a rapid, dry, insect-like trill of identical chip notes, varying in speed and length. They also give a high, hard "seep" or "tsik" call.
04 / The life behind the feathers
Their diet shifts seasonally; primarily insects and spiders during spring and summer, including caterpillars, grasshoppers, and beetles. In fall and winter, they mainly consume seeds from various grasses and weeds, and some waste grain.
Chipping Sparrows primarily forage on the ground, hopping or running through grasses to find seeds and insects. They will also glean insects from foliage and visit bird feeders for seeds.
The female builds a flimsy, cup-shaped nest of rootlets and dried grasses, often lined with animal hair, typically 1-6 meters off the ground in a tree or shrub. She lays 3-5 pale blue-green eggs, and may produce two broods per season.
During the breeding season, males defend territories and sing from elevated perches. After breeding, they often form loose flocks, foraging together. They are generally considered tame and well-adapted to human presence.
One more reason to pay attention
Chipping Sparrows were once known as "hair birds" due to their habit of lining nests with horsehair, and now use hair from other mammals.
The nest is often so loosely constructed that light can be seen through its walls.
The oldest recorded Chipping Sparrow lived to be at least 10 years and 11 months old.
05 / An eye for the difference
Clay-colored Sparrows have a brown rump (not gray), a clearer face pattern, and often a buffy wash on the underparts.
Brewer's Sparrows are duller overall with a less distinct facial pattern and a brownish rump, lacking the Chipping Sparrow's crisp markings.
