PIGEON HAWK. Il 
a more certain refuge in diving beneath their yielding element. 
If the prey be not too large, the Falcon mounts into the air, 
bearing it off in his talons, and then alights to gorge himself 
with his booty at leisure. Sometimes he attacks the Kite, 
another fellow-plunderer, either in wanton insult, or more 
probably to rob him of his quarry. 
The Peregrine is very generally distributed throughout America, 
but excepting on the Atlantic coast of Labrador, and possibly on 
Newfoundland, it is nowhere common in this faunal province. It 
is a winter visitor chiefly in Ohio and southern Ontario, but it is 
known to breed on isolated cliffs in the Maritime Provinces and the 
New England States, and it is said that nests have been found in 
Pennsylvania and Maryland. The report of its building in a swamp 
in New Jersey has not been confirmed. 
PIGEON HAWK. 
FaLcoO COLUMBARIUS. 
Cuar. Generally the prevailing color, above, is blackish brown, though 
the older birds assume a dull tint approaching bluish gray; wings, back, 
and tail streaked and barred with buffy or reddish brown. Tail tipped with 
white ; the middle tail-feathers in male with four bands of blackish, and 
in female about six pale bands. Below, dull, pale reddish brown, lighter 
on breast and throat. Length 11 to 13 inches. 
Nest. Usually on branches of trees, though found sometimes in cavi- 
ties of dead trees and on cliffs; loosely built of twigs, and lined with grass 
and leaves. 
Eggs. 3-6; buffy or pale reddish-brown ground color, blotched with 
dull red and brown ; 1.30 X 1.55. 
This species is a little larger than the following, but by no 
means so abundant; though met with in latitude forty-eight 
degrees by Long’s Northwestern Expedition, and occasion- 
ally extending its migrations from Texas to Hudson’s Bay, and 
rearing its young in the interior of Canada. Its nest was also 
observed by Audubon in Labrador in the low fir-trees, and con- 
tained five eggs, laid about the 1st of June. It is shy, skulk- 
ing, and watchful, seldom venturing beyond the unreclaimed 
forest, and flies rapidly, but, I believe, seldom soars or hovers.
