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

Hab. — Northern regions, from Atlantic to Pacific ; in winter south, through most of the United States. 
The northern shrike is onl)' 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.
