188 ZOOLOGY. 



the 28th of April, 1856. It was shot by my servant, who described it as being excessively 

 wild and difficult to approach. 



This is the only specimen of the species I have seen, and I consider it therefore accidental 

 west of the Cascade mountains. S.

 tail coverts hoary white. Beneath white, the breast with fine transverse lines. Wings and tail black; the former with a 

 white patch at base of primaries and tips of small qu lls; the latter with the lateral feathers tipped with white. Bill blackish

Hub. Northern regions, from Atlantic to Pacific; in winter south, through most of the United States. 



The northern shrike is only a winter resident in the Territory, appearing along the coast in 

 November and remaining until March. It frequents bushy places, and seems to live chiefly on 

 insects. I never saw them attack small birds, though often in company with them. C. 



I obtained one specimen of this shrike at St. Mary s valley, Washington Territory, in 1853. 

 As a group the butcher birds are but poorly represented in number in Oregon or Washington 

 Territories. S.
