are banded across, on an asli-colored ground. The length is about twenty inches. It builds in 
remote forests or on rocky peaks, and lays two to four eggs. It feeds on grouse, pheasants, 
partridges, pigeons, ducks, and geese. It is common in all the United States, especially along the 
sea-coast. Audubon speaks of it in Louisiana, and Richardson in the region of Melville Island. 
Wilson gives us a lively description of the manner in which this fine and powerful bird darts down 
upon the ducks along the shores of New Jersey and Pennsylvania, carrying terror and dismay 
among the myriad flocks that gather at particular seasons in that quarter. In the breeding 
time it retires to the gloomy cedar swamps, on the tall trees of which it constructs its nests 
and rears its young, secure from all molestation. In these wilds, -which present obstacles almost 
insuperable to the foot of man, the screams of this bird, occasionally mingled with the hoarse 
tones of the heron and the hooting of the Great Horned Owl, echoing through the dreary soli- 
tude, arouse in the mind all the frightful imagery of desolation. 
The Western Peregrine Falcon, F. nigriceps, found in lower California and Chili, greatly 
resembles the preceding, but is smaller. 
The American Lanner Falcon, F. polyagrus, is brown above and white below ; the length is 
twenty inches ; found in California, on the Platt River, and near Puget's Sound. 
The Hobby or Hobby-Falcon — the Hohereau of the French — F. subbuteo, formerly used in 
hawking at larks and quails, is eleven inches long, of a bluish ash-color above, white below, tinged 
with red. It builds in lofty trees, or in the orevices of high rocks, laying three or four reddish- 
white eggs. It is found in Southern Europe and I^orthern Africa, and feeds largely upon larks, 
which it captures by soaring above and then pouncing down upon them. It also devours other 
small birds, and frequently condescends to sup on frogs, beetles, and crickets. Swallows have 
such fear of this hawk that when pursued by it they sometimes fall insensible to the ground 
from mere fright.
