Songs
The song of the White-crowned Sparrow Is one of the most-studied sounds in all of animal behavior. Different subspecies across the country sing clearly different songs, but they’re all recognizable by the sweet, whistling introduction, a succession of jumbled whistles, and a buzz or trill near the end. Songs last 2-3 seconds. Females sing only rarely.
Calls
White-crowned Sparrows have about 10 different calls. The most frequently heard include a sharp pink, lower-pitched than the White-throated Sparrow’s call. It’s usually made by males or as an alarm call near the nest. They also make a harsh, rasping call used by sparrows during altercations.
Backyard Tips
White-crowned Sparrows come to feeders for sunflower and other kinds of seeds – though they may be more likely to stay on the ground eating seeds dropped by other birds. Making a brush pile in your yard is another good way to encourage this species to spend more time in your yard.
Find This Bird
The White-crowned Sparrow is a winter bird across much of the U.S (exceptions are the West Coast and mountains of the West). Start looking for these birds to arrive sometime in September, and they’ll be in fields, along roadsides, in low foliage at trail edges, or hopping around the margins of your yard until March or April.
