Abstract

The Le Conte’s Thrasher (Toxostoma lecontei) can be identified by its moderately decurved bill, medium size (9.5 in.), and plain gray-brown colors. The dark black-brown tail contrasts with the upperparts and more so with the paler underparts. The Le Conte’s has a pale buffy crissum while its nearest two relatives, the California (T. redivivum) and Crissal (T. crissale) Thrashers, are larger and darker and have cinnamon (California) or deep cinnamon-rufous (Crissal) crissums. Fortunately, over much of its range the Le Conte’s Thrasher does not come into direct contact with these two related species. After the summer molt (complete for adults and incomplete for young of the year), the body plumage is considerably darker than that found from November to July. There is no sexual dimorphism beyond possible minute differences in size.
