538. Calcarius ornatus (Towns.). 



Chestnut-collared Longspur. 

 Summer resident ; but so far as known rare. There are 

 some records given by Coues, such as Black hills and Running 

 Water which may belong to Wyoming; but are not so con- 

 sidered here. In Coues' Key to North American Birds, p. 360, 

 there is the following note : "Breeds in profusion on the prair- 

 ies of Colorado, northward, in parts of Dakota and Montana, 

 etc." The only absolute records of this species in Wyoming 

 are those from Bond, who has taken at Cheyenne the following 

 specimens: In 1889, on April 17, 2; April 18, 1 ; April 21, 2; 

 March 16, 1890, 1. 



539. Rhynchophanes mccownii (Lawr.). 



McCown's Longspur. 

 Summer resident, and locally breeding in great numbers. 

 These are nearly as abundant during the breeding season on 

 the Laramie plains as the Desert Horned Lark, and the West- 

 ern Vesper Sparrow. Coues reports this species from Wyo- 

 ming. Allen has published the following note (Bui. M. C. 

 Z., Ill, 1872, pp. 145-177) : Cheyenne, Wyoming Terr., abund- 

 ant, breeding. Jesurun finds them abundant at Cheyenne. 

 Specimens in Bond's collection were taken April 8, 17, 18, 

 1888-89, and on Oct. 14th and 20th, 1888. There are three 

 skins in the University collection that were taken on the Lara- 

 mie plains on the 21st and 23rd of May, 1897. I have also 

 taken one specimen on Chugwater creek on May 29, 1898. 



540 a. Pocecetes gramineus confinis Baird. 

 Western Vesper Sparrow.

 elevations all over the state. The following have reported this

 mie, 1858; Drexel, Fort Bridger, 1858; Aiken, Sherman, 1870;
