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 was 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 
see 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 different 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 quite 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 oven thrice in a day, and yet always contrived to escape unmolested. 
This species is frequently known among the Oregonians as the “ blue hawk.” The goshawk 
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 young 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.

This hawk is commonly confounded with others, under the name of “chicken hawk.” It is 
very abundant in summer, and 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
