With their dull, brownish-gray backs and white wing bars, they're often mistaken for Juvenile Mockingbirds. The strong streaking/speckling on the breast, along with the stubbier bill and shorter size (8 1/2 inches to the mockingbird's 10) does set the Sage aside both from the Mockingbird and other Thrashers.
The Sage Thrasher is uncommon, and given its rather drab appearance I'm glad we saw one when we did, because I don't know if I'll otherwise notice and take the time to tell it apart as a new bird. This Thrasher was a new one for the List.
|Note the grayish back and wing-bars, very similar to a young Northern Mockingbird|
|The streaked flanks and breast, along with the yellow eye and white rump are visible as this Sage Thrasher makes his escape past the creosote bushes.|
