702. Oroscoptes montanus (Townsend) — Sage Thrasher. 



Rare, and so far as known, confined to northwestern Nebraska. 

 Baird's "Nebraska" records are now extralimital, referring to Ft. 

 Laramie and the Black hills. A. K. Fisher saw a single bird at a dis- 

 tance of six feet at Alliance, Box Butte county, July 12, 1893, and 

 it has been found nesting within a half mile of the Nebraska line in 

 Wyoming, May 20, 1900, by Cary and Carriker. Residents of the Hat 

 Creek valley report it as occasional in that region. 



703. *Mimus polyglottos (Linnaeus) — Mockingbird, and 



703a. *Mimus polyglottos leucopterus (Vigors) — Western Mockingbird. 

 This bird is found throughout the entire state ; south of the Platte 

 a common summer resident and breeder; rare north of middle of 

 state. Arrives in the middle of April, breeds in June, departs 

 about the middle of October. Rulo, Nebraska City, Weeping Water, 

 Lincoln, Beatrice, Franklin, Kearney, North Platte, McCook, Strat- 

 ton, Haigler, Sidney — breeding; even north to Sioux county, though 

 not common — breeding. Specimens from the last locality much paler 

 in color and with more extended white markings than eastern birds 

 have been identified by Witmer Stone as leucopterus , and there is 

 no doubt the Sidney record refers to the same form. In regard to the 

 records from other localities westward, however, it is impossible, in 

 the absence of specimens, to make a definite statement; nor is it pos- 

 sible to limit the range of the two in the state. 



704. *Galeoscoptes carolinensis (Linnaeus) — Catbird. 



Whole of state; abundant eastward, common westward, arriving 

 the first week in May, breeding in June, departing late in September. 



705. *Toxostoma ruium (Linnaeus) — Brown Thrasher. 



Over the entire state; abundant except in the more western por 7 

 tions, breeding throughout. Arrives late in April, breeds late in May, 

 and in June, departs late in September.
