ing five slightly incubated eggs was found on June 14, 1900. 

 The nest was on the ground and composed of grass, the lining 

 was fine grass and horse-hair. Eggs similar to those of C. 

 grammacus." 



553. Zonotrichia querula (NuTT.). 



Harris's Sparrow. 



Migratory; rare. Dr. Jesurun has two skins in his col- 

 lection that were taken on Oct. 7 and 15, 1894. No other Wyo- 

 ming records. It is quite probable that this species is more 

 abundant to the northward, for they are occasionally reported 

 from Oregon. 



554. Zonotrichia leucophrys (Forst.). 



White-crowned Sparrow. 

 Summer resident, and common in the lower mountain re- 

 gions. Breeds abundantly from 8,000 to 9,000 feet. It has 

 not been noted above timber line in Wyoming. The following 

 records have been secured: Taken by Wood, Cheyenne pass 

 and Pole creek, July 20 and 28, 1856; Stevenson, Wyoming, 

 1870; Aiken, Sherman, 1870; Coues, several Wyoming speci- 

 mens ; Grinnell "abundant in Yellowstone park. It was seen 

 during August and September in small flocks of 10-12 indi- 

 viduals, old and young, feeding on the ground in company with 

 A. arctica and a host of small sparrows (1875)." Also report- 

 ed by Merriam from the Yellowstone park, 1872 ; Bond, com- 

 mon at Cheyenne. There are a half dozen skins in the Uni- 

 versity collection that have been taken from the following lo- 

 calities: Chugwater, Tepee creek. Ten Sleep lake and Lara- 

 mie. The National Museum reports Nos. 11 141 and 11 148 

 taken at Fort Bridger and No. 88060 at Fort Laramie. I have 

 observed these birds at Atlantic, Evanston, Fossil, Saratoga, 

 Casper Mountain, Ervay, Meeteese creek, head of Clear creek, 

 near Buffalo and Medicine Bow mountains. I am inclined to 

 think that the early records are not reliable in this instance and 

 may prove to be in part S54a. Ridgway in Bull. 50 (Birds of
