The Birds of Wyoming. 133 



567 1. Junco montana Ridgw. 

 Montana Junco. 

 Possibly a winter resident. But little is known of this 

 species. It is very certain that data originally referred to the 

 Oregon Junco in part belongs to this species. These birds ar- 

 rive in Laramie about the middle of March and remain for 

 only a few weeks. There is one skin in the University col- 

 lection that was taken at Laramie, Sept. 27, 1898. The Na- 

 tional Museum has the following numbers belonging to this 

 species, that were taken in Wyoming: 71 114, taken by A. G. 

 Brackett, and 11 180 and 11 186, taken by Drexel at Fort 

 Bridger. 



568. Junco mearnsi Ridgw. 



Pink-sided Junco. 

 Probably a summer resident, and rather common in the 

 mountains of the northern part of the state. During migra- 

 tion common over the state. Bond has taken several specimens 

 at Cheyenne and states that they are common during the spring ; 

 Jesurun reports them common about Douglas. The following 

 numbers of the National Museum collection belong to this 

 species: 11 168, taken at Fort Bridger; 138543, South pass, 

 L T . S. Dept. Ag. ; 11187. Fort Bridger, Drexel. West has sent 

 one skin from Buffalo. There are three other skins in the 

 University collection that were taken on the Laramie plains. I 

 have seen this species in the Big Horn mountains near Ten 

 Sleep lake during the months of July and August. Many of 

 the birds were quite young. While I am quite certain they 

 breed in that region I have never seen their eggs nor nests. 



569. Junco caniceps (Woodh.). 



Gray-headed Junco. 



Summer resident, and a few may remain all winter. Com- 

 mon in the mountainous districts from 8,000 to 10,000 feet. 

 Breeds in the Laramie and Medicine Bow mountains and 

 Freezeout hills. There are the following records pertaining to 

 the capture of this species in Wyoming: Drexel, Fort Bridger,
