The Brewer’s Sparrow is a small, pale gray-brown sparrow found in Arizona, particularly in the northern and central parts of the state. It is best recognized by its subtle streaking, indistinct facial markings, and long, notched tail. Two subspecies occur: the timberline sparrow (Spizella breweri taverneri), which is associated with shrubby alpine and subalpine habitats farther north, and the nominate Brewer’s Sparrow (Spizella breweri breweri), which is the form present in Arizona.
In the state, Brewer’s Sparrows are most often encountered in sagebrush habitats of the Colorado Plateau and in open shrublands and pinyon-juniper grasslands. They are common summer breeders in northern Arizona but migrate south in winter, when smaller numbers can be found in desert washes and grasslands at lower elevations.
Brewer’s Sparrows feed primarily on seeds, but during the breeding season they take insects to feed their young. Their soft, tinkling song is a characteristic sound of sagebrush country in spring and summer. Although still widespread, populations have shown declines linked to the loss of sagebrush ecosystems across the West.
