Dusty-brown bird with long tail, found in shrubby deserts and grasslands. Tail dark with small white corners; undertail coverts warmer orangey. Eye yellow. Very similar to Curve-billed Thrasher. Subtle differences include smaller, more triangular-shaped markings on breast, and shorter, straighter bill. Shy; often hard to spot on the ground but sometimes perches conspicuously when singing. Ages and sexes similar; juveniles show faint buffy wingbars. Listen for jumbled, rambling song.
