Large Nests in Trees 
The nesting season begins ftom early in April to early in 
June, according to locality. 
SSS. Cooper’s Hawk: Accipiter cooperii (Bonap.) 
Adult—Resembling the sharp-shinned hawk ; the dark crown, 
rounded tail, and superior size, are the most marked differences. 
Length— 2, 15.50; @, 19.00. 
Breeding Range—Throughout the Eastern States. 
The nest is large and bulky ; it is made of sticks. Often a 
deserted crow’s or hawk’s nest is used, otherwise the nest is 
placed near the top of a tree, generally ina crotch. The eggs 
number from 4 to 6; they are white, more or less tinged with 
green or blue, either immaculate or with light reddish-brown 
spots. Size—1.97 x 1.50. See Fig. 4, Plate A. 
This is one of the many so-called chicken hawks, and it de- 
serves the name far better than many of the other hawks, as it 
destroys a great number of poultry. 
The breeding season, near New York, begins about the end 
of April, and in the South about the first of April. 
334. American Goshawk: Accipiter atricapillus (Wils.) 
Adu/t—Upper parts slate colour ; head much darker; line over 
eye white ; under parts whitish, with broken bars of dark 
gray.

with very dark grayish brown. Length—é, 22.00; 9, 
24.00. 
Breeding Range—From the more northern parts of the United 
States northward. 
The nest is made of sticks, lined with coarse pieces of bark 
and grass ; it is placed in tall trees, usually evergreens. The 
eggs, numbering from 2 to 5, are whitish, sometimes tinged with 
blue or green, either unmarked or with light brownish spots.

This bird resembles the European goshawk, which was 
used to catch hares and rabbits in the time when falconry was so 
much the fashion.
