1914 BIRDS OF ARIZONA 73 



325. Mimus polyglottos leucopterus (Vigors). 



WestI^rn Mockingbird. 



Synonyms — Mimus polyglottiis; Mimus polyglottus var. candatus. 

 Status — A common summer visitant in the Lower Sonoran valleys, and in 

 places extending up into Upper Sonoran. It is permanently resident in the hot 

 valleys of southern Arizona, but there is a vertical migration downward from the 

 foothill regions where it occurs in summer ; and possibly an entire departure from 

 northern Arizona during the winter months. Coues (1866a, p. 65) speaks of it 

 as a summer resident only in the vicinity of Fort Whipple, and Osgood (1903, p. 

 150) mentions its arrival in the Sulphur Spring Valley, Cochise County, on April 

 15. In the foothills of the Huachuca Mountains it occurs in summer only, while 

 it is reported in February from a point on the San Pedro River, fifteen miles dis- 

 tant and about five hundred feet lower (Willard, 1910c, p. no). The few records 

 from northern Arizona (Little Colorado River, Keam Canon, and Hualpai Moun- 

 tains), are all for the summer months. 



Probably a winter visitant only on the Colorado River below Needles (Mus. 

 Vert. Zool.). 



326. Toxostoma rufum (Linnaeus). 



Brown Thrasher. 



Status — But one record for Arizona, that of a male bird taken in the foot- 

 hills of the Huachuca Mountains (4500 feet altitude), on October 5, 1907 

 (Swarth, 1908, p. 115). 



327. Toxostoma cnrvirostre palmeii (Cones). 



PALM3iR Ti-TRASHSR. 



Synonyms — 7 oxnstoma vctiila: Harporhvnclins curvirostris ; Harporhynchus 

 cnnnrostris palricri. 



Status — A common resident in the Lower Sonoran valleys of southeastern 

 Arizona. Its range has been traced east to the valley of the San Pedro (Brew- 

 ster, 1882, p. 71), north to the Hassayampa (1. c.) and the Big Sandy (Stephens, 

 1903, p. 105), to Fort Grant (Coues, 1868, p. 83) and the Salt River Valley. 



328. Toxostoma bendirei (Coues). 



Bendire Thrasher. 



Synonyms — Harporhynchus bendirei; Harporhynchus cincrcus var. hcndirei. 



Status — Locally a common resident in the Lower Sonoran valleys of south- 

 eastern and northeastern Arizona, but our present knowledge seems to indicate an 

 exceedingly irregular and disconnected range. In southeastern Arizona it is very 

 abundant in the valley of the Santa Cruz, west of the vSanta Rita Mountains, whih 

 it is almost unknown east of that range. It is common in the plains and valleys 

 stretching northwest of Tucson, as far as Phoenix and along the Gila River at 

 least as far as Gila Bend (Pember, 1892, p. 6). In northern Arizona it has been 

 reported from Keam Canon in July and August (Fisher, 1903, p. 35), and from 

 Beale Spring in July (Stephens, 1903, p. 105).
