Close up of a Sage Thrasher.

Sage Thrasher

Sage thrashers have a long, melodious flutelike song with a lot of variety in notes. The longest documented song was approximately 22 minutes long! Sage thrashers may also mimic the notes of other birds and have been called “the mockingbird of the sagebrush.”

Oreoscoptes montanus


The sage thrasher is the smallest of all thrashers, 8-9 in/20-23 cm, a little smaller than a robin. It has a small bill, yellow eyes, two thin, white wingbars, and a grayish-brown back with streaking on the breast and belly. Its tail is long with white corners. They maintain their coloration year-round, and males and females look similar.

Observation Tips

Sage thrashers can be seen and heard singing from the tops of the tallest shrubs in the springtime as males begin to court females. They are elusive when alarmed and will flick their tail repeatedly in response. They often run on the ground rather than fly. Sage thrashers will also fly in low, undulating circles and flutter their wings upon landing in a courtship display. They arrive on their breeding grounds in March or April.  From their breeding grounds in the Intermountain West, sage thrashers begin their migration in August. They winter in the southwestern U.S. and in northern Mexico.

Ideal Habitat

In the breeding season, sage thrashers are found in sagebrush shrublands, especially with taller, older stands of big sagebrush and limited grass cover. They nest most commonly in sagebrush shrubs, but will also use greasewood, rabbitbrush, bitterbrush, and juniper shrubs. Nesting shrubs are usually taller, >27 in/69 cm, and more vigorous than surrounding shrubs. During migration and winter, sage thrashers use a wide variety of open, arid habitats, such as grasslands with scattered shrubs and open pinyon-juniper woodlands. They feed on insects from the ground, especially ants, beetles, and grasshoppers. They also occasionally eat seeds and small fruits.

Management Activities that Benefit Species – Best Management Practices (BMPs)

Maintain large stands of older, dense sagebrush. Control invasive plants, such as cheatgrass, and avoid creating crested wheatgrass monocultures. Sage thrashers will avoid trees, so reducing encroaching trees, such as junipers.

Management Activities to Avoid

Avoid using extensive prescribed fire as it will eliminate sagebrush and other shrub cover. Additionally, where possible, refrain from other management actions that reduce or eliminate sagebrush canopy cover, such as mechanical sagebrush removal and herbicide application.

Other Species that Benefit from Similar Habitat Management

Other sagebrush-obligate species will likely benefit from habitat management for sage thrashers, such as Brewer’s sparrows, sagebrush sparrows, greater sage-grouse, and pygmy rabbits.
