You’ll find Chipping Sparrows around trees, even though these birds spend a lot of time foraging on the ground. Look for them in grassy forests, woodlands and edges, parks and shrubby or tree-lined backyards. Chipping Sparrows seem to gravitate toward evergreens in places where these trees are available. They also use aspen, birch, oak, pecan, and eucalyptus trees. In the mountains, you can find these birds all the way up to treeline.Back to top
Chipping Sparrows mainly eat seeds of a great variety of grasses and herbs. During the breeding season they also hunt for protein-rich insects, and these form a large part of their summer diet. Chipping Sparrows sometimes eat small fruits such as cherries.Back to top
Females typically build their nests between 3 and 10 feet off the ground, hidden in foliage at the tip of a branch. They gravitate toward evergreen trees, but also nest in crabapples, honeysuckle tangles, maples, ornamental shrubs, and other deciduous species. Females can be finicky about placement, often beginning to build a nest, then leaving to begin in another spot.
Males guard females as they build nests, but they don’t help build. It takes the female 3 to 4 days to finish her nest, a loose cup of rootlets and dried grasses so flimsy you can often see through it. She lines the nest with animal hair and fine plant fibers. Finished nests measure about 4.5 inches across and 2.2 inches deep.

In summer, male Chipping Sparrows defend territories against other Chipping Sparrows, but often tolerate other species as long as they don’t go too near the nest. After the breeding season, Chipping Sparrows form flocks of several dozen, foraging together among grasses and at bird feeders. Their flight pattern is energetic, straight, and only slightly undulating.Back to top
Chipping Sparrows are common across the continent, but overall the species declined by about 36% between 1966 and 2015, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 230 million, with 38% spending some part of the year in the U.S., 49% in Mexico, and 56% breeding in Canada. The species rates an 8 out of 20 on the Continental Concern Score. Chipping Sparrow is not on the 2016 State of North America's Birds' Watch List. These birds thrive in open, tree-filled spaces that go along with suburbs and parks, so in some areas their numbers have increased as humans settled the landscape.Back to top
Chipping Sparrows will eat many kinds of birdseed, particularly black oil sunflower seeds from feeders, but also seed mixes scattered on the ground. Shrubs or small trees in your yard may entice Chipping Sparrows to build a nest.
This species often comes to bird feeders. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list.Back to top
