Falco peregrinus (GmeL), (Peregrine Falcon). 
Trout Lake Station and Severn House, Hudson's Bay. 
Sir J. Eichardson says this bird is frequent in the barren grounds. 
Sir W. Jardine tells me it is the Falco anatum, Bonap., of 
the American ornithologists. Well known at New Jersey 
from the havoc it makes among the water-fowl in winter. Mr 
Ord says, that the ducks when struck by it are lacerated from 
the neck to the rump.

The male varies from the European specimens, in the upper parts 
being darker, and in the lower breast and the belly being 
barred at wide intervals with pale sienna, — agreeing in this 
respect with the figure given by Bonaparte in his continua- 
tion of "Wilson's North American Ornithology." The young 
male differs in the darker general plumage and the deeper tint 
of the sienna on the under parts.
