from an elevation of several hundred feet. They also often 

 perch upon some tree, as in a meadow, and watch for move- 

 ments in the grass. They are somewhat shy and difficult to 

 approach, but they are bold enough to carry off poultry, and 

 I have been told of one actually caught in a hen-house.

(). Much less stout than the " Red-tail," and less in aver- 

 age size, the female being rarely or never more than twenty- 

 three inches long. The coloration is variable, but the follow- 

 ing description of a fine mature specimen will answer for 

 others. Above, dark brown. Head, streaked with rusty and 

 white; back and rump marked with the same colors. .Tail, 

 and quill-feathers, black ; the former tipped, and both barred, 

 with white. Shoulders, rich rufous or pheasant-brown. Be-

 rufous wanting or restricted. Beneath, white, streaked (and 

 spotted) with dark brown. "Tail beneath silvery white." 

 Under wing-coverts usually more or less fulvous as in the 

 adult. 



(b). The " Hen Hawks" generally build a fresh nest every 

 year, though they may occasionally occupy the same nest u for 

 several seasons," as Mr. Samuels states to be the case. Should 

 their home be destroyed during the season of incubation, they 

 usually repair an old nest for a second brood, as they some- 

 times do for their first. Their nest, when finished, is a large 

 structure of sticks (from eighteen to thirty inches in diameter), 

 and is commonly lined with small branches of hemlock, or 

 with tree-moss. It may be found in rather secluded or unfre-
