Sage Thrasher

The Sage Thrasher is the smallest thrasher species in North America and is closely tied to sagebrush steppe habitats of the western interior. Unlike many of its longer-billed relatives, it has a comparatively short, straight bill, giving it a more thrush-like appearance, and it is often seen running along the ground between sagebrush clumps.

Flight feathers: grayish-brown with pale wing bars formed by whitish tips on the coverts, more compact than the flight feathers of larger thrashers. Tail feathers: shorter than in other thrashers, dark grayish-brown with white corners visible from below, especially in flight. Body feathers: gray-brown above with heavy, crisp dark streaking on a whitish breast and belly, and a bright yellow eye. This combination of a shorter, straighter bill, bold breast streaking, and white tail corners readily distinguishes Sage Thrasher feathers from the longer-billed, faintly spotted or unspotted Curve-billed and California Thrashers.

Sexes look alike. Adults are gray-brown above with bold blackish streaking on whitish underparts, pale wing bars, white tail corners, and a bright yellow eye. Juveniles show similar streaking but with buffier tones and less crisp pattern, converging with adult plumage after their first molt. There is no strong seasonal plumage difference in adults.

Sage Thrashers breed almost exclusively in sagebrush steppe and other arid shrub habitat across the interior western United States and southern Canada. The species is migratory, wintering in the southwestern United States and Mexico in scrub and desert habitats.

This thrasher forages mainly on the ground, running between shrubs to catch insects and other invertebrates, and also consumes fruit seasonally. It builds a cup nest low within a sagebrush or other dense shrub. Its song is a long, rich, sustained warbling series of varied phrases, delivered from a perch atop a shrub, and it is considered one of the more melodious thrashers.
