1914 BIRDS OF ARIZONA 73 



325. Mimus polyglottos leucopterus (A'^igors). 



WKSTKKN yi UCKINGBIRD. 



Synon\nis — Mimus polyglottus ; Mimus polyglottus var. caudatus. 



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

 ])Iaces 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, d. 

 T50) mentions its arrival in the Sulphur Spring Valley, Cochise County, on April 

 15. In the foothills of the Iluachuca INIountains 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). 



Brow^n 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). 



T^2y. Toxostoma ciirvirostre palmeii (Coues). 



Palmer Thrasher. 



Synonyms — Toxostoma vctuJa: Harporhviuiius curz'irostris ; Harporhynchus 

 cnnirostris palnrri. 



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. T882. p. 7tL north to the Hassayamna (1. c.) and the Big Sandy (Stephens, 

 i(>33. p. 105), to Fort Grant (Coues. 1868, p. 83) and the Salt River Valley. 



328. Toxostoma bendirei (Coues). 



Bendire Thr.vshER. 



Synonyms — Harporhynchus bendirei: Harporhynchus cincrcns var. bendirei. 



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

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

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

 abundant in the valley of the Santa Cruz, west of the Santa Rita Mountains, whil; 

 it is almost unknown cast 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 

 Boalc Spring in July (Stephens. 1903. p. T05).
