British Columbia. John Fannin. Common sum- 

 mer resident. 



Henshaw. Numerous throughout all the heavily wood- 

 ed portions of the region. 



Camp Harney. Capt. Bendire. Moderately com-

Hoffman. A common species throughout the wooded 

 valleys in winter; ascending to the more elevated tim-
