TOXOSTOMA CINEREUM CINEREUM (Xantus). 

 SAN LUCAS THRASHER. 



Most nearly related to T. hendirei, but bill larfi;er and spots on under 

 parts much larger and blackish instead of grayish brown. « 



Adults in spring and summer. — Above plain grayish brown (hair 

 brown or l)etween hair brown and broccoli brown), more decidedly 

 brown (wood brown) on rump and upper tail-coverts, the remiges and 

 rectrices darker; middle and greater wing-coverts more or less dis- 

 tinctly tipped with paler, usually with white, forming two narrow 

 bands ;^ remiges edged with paler grayish brown, these edgings ap- 

 proaching dull whitish on primaries ; inner web of outermost rectrix 

 broadly tipped with dull vrhite, the outer web more narrowly tipped 

 with the same; other rectrices (except middle pair) similarly marked 

 but the whitish tip narrower; sides of head dull whitish, the auricular 

 region streaked, the suborbital and malar regions flecked or barred, 

 with grayish brown; under parts buffy white, passing into pale l)uff 

 on posterior flanks, anal region, and under tail-coverts; chest marked 

 with triangular or wedge-shaped spots of black or blackish brown, the 

 breast, sides, and upper abdomen similarly but more sparsely marked ; 

 throat margined along each side by a more or less distinct series of 

 small wedge-shaped spots or streaks of blackish; bill dusky horn color 

 or blackish, the basal third (more or less) of mandible light brownish 

 (in dried skins); iris yellow; tarsi horn color (in dried skins), the toes 

 more dusky. 



Adults in autumn and winter. Siniilar to the spring and summer 

 plumage, but color of upper parts grayer, and tertials margined ter- 

 minally with whitish. 



Young. — Essentially like adults, but pileum, hindneck, and back 

 light buffy grayish brown (between broccoli brown and wood brown), 

 passing into cinnamon on rump and upper tail-coverts; middle and 

 greater wing-coverts tipped with cinnamon-buft", the tertials margined 

 terminally with the same; markings on under parts much smaller, 

 more linear. 



"The coloration of this species presents a reniarkal)l(" rcsoinltlance to that of Oroscop- 

 tes montanus. 



6 These bands somelinies obsolete, especially in worn niidsunnner plumage.
