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

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 valle}-, Washington Territory, in 1853. 

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

 Territories. — S.
