with the scales almost wanting. Species distributed over the whole world. 
Three inhabit the United States, one of which—A. Mexicanus—is limited 
to the Pacific coast and Mexico. 
I. A. CoopERtI—Bonaparte—CoorPeEr’s HAwK. 
Audubon’s B. of Am., Oct. ed., I, pl. 24. 
This hawk is much more injurious to the farmer than we might be led 
to believe from its comparatively small sized and slender form, but its 
great courage and rapidity of flight enables it to combat and destroy much 
larger birds than itself. Audubon relates an instance in which a young 
male attacked a cock and succeeded in killing him, although the fowl was 
prepared for the combat. The marauder paid the penalty of his foray 
with his life, Mr. Audubon having shot him in the act of rising in the air 
after the battle. 
Cooper’s hawk destroys great quantities of game, and often visits the 
farm-yard for the purpose of preying on everything it can conquer. It 
builds its nest in the forked branch of some tall tree, often an oak. The 
eggs are three or four, nearly round, of a dull white, and very rough. 
It is rather difficult to distinguish the species sometimes, as the varia- 
tions of the plumage are considerable, and the markings vary. Its formis 
slender, with short wings and rounded tail. In the adult, the upper part 
of the head is brownish black, with a few marks of white. Upper parts 
of the body dark ashy brown, with an obscure reddish collar on the back 
of the neck. ‘Tail dark slate color, with four broad bands of black, and 
tipped with white; under tail coverts white. Throat white, with lines of 
dark brown. Breast and abdomen barred with light-reddish and white. 
The female measures from eighteen to twenty inches in length; the 
male sixteen to seventeen. 
Specimens in the Cleveland Academy Museum. 
Since writing the article on the Goshawk, we have seen specimens, and 
had an opportunity to examine and compare these with the Huropean spe- 
cies—A. palumbarius—and from that examination we would be led to con- 
sider that they were quite distinct. Our Goshawk has been shot in the 
neighborhood of Cleveland, and Dr. Kirtland informs us that they are very 
numerous in Wisconsin. He has seen them flying around, and can distin- 
guish them ata glance, from their peculiar method of flight. Dr. Sterling 
shot a specimen in this vicinity that is now in the possession of the Hon. 
William Case.
