REMARKS : 
Fig. 2, Plate XLIX, represents the usual sizes, shapes, and colors of the eggs of the Cooper’s Hawk. 
Two of the eggs figured were collected by Mr. Chas. Dury, April 29th, 1879, near Cincinnati; the other 
egg figured, came from a set collected in Ross County, in May, 1880. 
My experience in collecting the eggs of this species has been very limited. I have found numbers 
of nests, but never an accessible one that contained fresh eggs. I raised from a nestling a male Cooper’s 
Hawk, and kept him until he was nearly a year old. He was an interesting pet, full of cunning and 
boldness. He became so tame that he had the liberty of the town. He would wander about from 
tree to house-top, and would sometimes be gone a whole day. He was very fond of buggy-riding, and 
would sit on the dash-board for hours manifesting the greatest interest in the objects passed. I intended 
to teach him to hunt, and was making rapid progress with his lessons, when I was obliged to leave for 
college. Some months later a letter brought me news of his death. A boy had killed him with a stone, 
The Cooper’s Hawk, or the Hen Hawk, as the species is called by the country people, is the most de- 
structive to poultry of any of the family. It is active on the wing, and of courageous spirit, and does 
not hesitate to attack birds much larger than itself. It catches many small birds upon the wing, and it 
sometimes even attacks ducks. I have twice seen a Cooper’s Hawk dart into a flock of Red-winged 
Blackbirds, and in each instance it secured a Blackbird in its talons.
