ZOOLOGY. 1 45 



This bird I met with in a dense spruce forest, where it was devouring a squirrel on the 

 ground. It flew into a tall tree and "w^as so closely concealed that I only discovered it after a 

 long search by seeing its tail move. I afterwards shot a beautiful specimen in full plumage, 

 which came darting like lightning through the dark forest, and alighted so near me that I could 

 sec its flashing eye; but not being killed at once, it managed to escape among some underbrush 

 and logs, where I sought it for an hour in vain. It would seem to be the special frequenter of 

 dark woods, where other hawks are rarely seen. — C. 



I obtained several specimens of the American goshawk, both at Fort Dalles and at Fort 

 Steilacoom. The specimens collected were in diiferent stages of plumage, one being a very 

 fine specimen of the adult. 



This hawk is bold, swift, and strong. It does not hesitate to sweep into a poultry yard, 

 catch up a chicken and make off with it almost in a breath. The manner of seizing its prey is 

 by a horizontal approach for a short distance, elevated but a few feet from the ground, a sudden 

 downward sweep or side glance, and then, without stopping its flight, making its way to a 

 neighboring tree or its nest with the struggling victim securely fastened in its talons. 



Considering the size of this bird, for strength, intrepidity, and fury, it cannot be surpassed, 

 these qualities almost rendering it feline in its character. It is also :juite cunning, seizing very 

 opportune moments for its attacks. It was not until many days that I was able to have a bird 

 of this kind killed, although men were constantly on the watch for him. So adroit was he at 

 seizing opportunities to make his attacks, that he would regularly visit our poultry yard twice 

 and even thrice in a day, and yet always contrived to escape unmolested. 



This species is frequently known among the Oregonians as the ^'■hlue hatvk." The gos- 

 hawk is found earlier than the others, and three specimens which I obtained were in most 

 elegant adult plumage. Why the birds of this family become so plentiful for a few months I 

 am unable to say, but think that, as above stated, having bred in the retired recesses of the 

 Cascade and Coast ranges of mountains, they remain until their j'oung are well able to fly, when 

 they all descend to the open plains, where they can obtain a more abundant supply of food, 

 such as finches, larks, robins, doves, band-tailed pigeons, meadow mice, moles, gophers, young 

 rabbits, and even grasshoppers. — S.

 and rufous ; beneath, white, with narrow light brown stripes. 



This hawk is commonly confounded with others, under the name of "chicken hawk." It is 

 very abundant in summer, aud often killed about farm yards, where it seizes on chickens before 

 the very eyes of the owner, darting down like lightning and disappearing again before he can
