I saw a practically continuous stream about seven miles long. It is hard to accu- 

 rately estimate the total number of individuals, but I think thirty thousand 

 would be conservative. 



DISTRIBUTION 



Range. — Montana and western Kansas to Louisiana: 

 Breeding range. — The thick-billed redwing breeds east of the 

 Rockies in western Montana (Teton and Gallatin Counties), western 

 Nebraska, and western Kansas (Decatur County) ; south through 

 southeastern Idaho (Bear Lake County), central and central-eastern 

 Utah (Salt Lake City, Spanish Fork, Moab), and Colorado to south- 

 western Utah (Pinto, Saint George), southern Nevada (intermediate 

 toward sonoriensis) , central and central-eastern Arizona (San Fran- 

 cisco Mountains, McNary), central and southeastern New Mexico 

 (Fort Wingate, Carlsbad), and (probably) northern and western 

 Texas (Boise, Canadian, Ysleta).

AGELAIUS PHOENICEUS NEVADENSIS Grinnell 



Nevada Redwing 

 HABITS 



This Great Basin redwing breeds from southeastern British Colum- 

 bia and northern Idaho, through much of northeastern California and 

 southward on the east side of the Sierra Nevada to San Bernardino 

 County, and through Nevada to eastern Arizona, New Mexico, and 

 western Texas. 



A. J. van Rossem (1926) in his study of the California races gives 

 this form the following diagnosis: "Bill stouter than in caurinus or 

 sonoriensis, but still decidedly more slender than in neutralis. Males 

 with exposed portions of middle wing coverts usually clear buff, 

 but frequently with a small amount of black present, and occasionally 

 with the exposed black even predominant over the buff. Females 

 decidedly less buffy than caurinus and with darker and broader 

 ventral streaking than in sonoriensis. Not always distinguishable 

 from neutralis in coloration, but streaking below averaging narrower 

 and sharper, and bill diagnostic if similar ages are compared." 



His seems more comprehensive and clearer than the original
