What Does a White Crowned Sparrow Look Like? Keys to ID
While white crowned sparrows may look ordinary at ﬁrst glance, their black-and-white-adorned heads, gray breasts and orange-colored bills let you know that royalty is on the premises. Males and females look the same, while friendly juvenile white crowneds feature bold nutmeg brown stripes on top of their heads. Those stripes typically turn black and white the following spring, when the bird is almost a year old.
A sparrow’s stout conical bill makes it the perfect tool for cracking seeds. According to the Cornell Lab of Ornithology, white crowned sparrows that breed along the Pacific Coast have yellow bills, while those that breed from Alaska to Hudson Bay sport orange. Birds that breed east of Hudson Bay and in the Rockies boast a pretty pink bill.

Range and Migration
Some of these handsome birds spend their summers on the tundra or in the alpine meadows and boreal forests of Canada and Alaska. For many living in the United States, their winter appearances are considered something special. “Over most of the country, white crowned sparrows are winter visitors, appearing between September and April,” says Dr. Emma Greig, head of Project FeederWatch at the Cornell Lab of Ornithology. “In the Northwest, they can be seen throughout the year. In areas through which they migrate—the Northeast and northern Midwest—people see them pass through in spring and then again in fall.”
What Does a White Crowned Sparrow Eat?
A white crowned’s year-round diet consists mostly of seeds and plant material. But once nesting season rolls around, they add insects into the mix. Nesting sparrows like to dine on and feed their hatchlings a variety of insects, such as caterpillars, wasps and beetles, that they sometimes catch in midair!
In winter, these sparrows travel in ﬂocks and are normally seen hopping through brush near open and overgrown ﬁelds or along low branches, where they forage for weed and grass seeds. “White crowned sparrows have a funny foraging behavior,” Emma says. “They do a backwards scratch with both feet and then a forward hop towards whatever they’ve unearthed. It’s a behavior that may be familiar because towhees, another ground forager, do it as well. When they do this in dry leaves, they can sound much larger than they really are.”

Nest and Eggs
Pairs often lay three to seven heavily spotted eggs that range from creamy white to green-blue in hue. Nests are made from moss, bark, pine needles, twigs and grasses, and then lined with ﬁne grass, animal hair and feathers. Females are the sole incubators, sitting on the nest for about two weeks until the eggs hatch.

How to Attract White Crowned Sparrows
Coaxing these foraging ﬂocks to your backyard is easy. “White crowned sparrows eat sunﬂower seeds, millet and cracked corn,” Emma says. “They prefer to eat on the ground, so scatter seeds there or offer seeds on a platform feeder.”
Emma also adds, “Like other sparrows, white crowneds enjoy a good brush pile, which offers cover and insects to small birds.”
Psst—don’t forget native sparrows at your bird feeders!
White Crowned Sparrow Song
Be sure to keep an ear out for the clear, sweet whistle of the male white crowned sparrow song (females also sing, but less so) in winter—a time when many other songbirds have stopped singing. Listen for differences in the songs. This species is famous for developing regional “dialects.” The singers you hear may have picked up their tunes from white crowneds in a completely different area.
