con ; indeed, the pale-coloured specimen scarcely differs from 

 some European specimens of that bird. 

 Falco peregrinus (Gmel.), (Peregrine Falcon). 



Trout Lake Station and Severn House, Hudson's Bay. 



Sir J. Richardson 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. 

 Falco candicans (Gmel.), (American Gyr Falcon). 



York Factory. 



A constant resident in Hudson's Bay territories, known as the 

 "speckled partridge hawk," and the " winterer;" 

 Circus cyaneus (Linn.), (var. Hudsonicus) ; or it may stand C. Hud- 

 sonicus, (Linn.) 

 From Moose Factory and Severn House. 



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. 

 Nyctea nivea (Daud.), (Snowy Owl).

 Severn House. 



Very forward, and intrudes itself upon man, but pines away in 

 confinement.
