BLACK GYRFALCON. 
FALcO RUSTICOLUS OBSOLETUS. 
Cuar. Prevailing color brownish black; usually barred with lighter

This elegant and celebrated Falcon is about two feet in 
length ; the female two or three inches longer. They particu- 
larly abound in Iceland, and are found also throughout Siberia, 
and the North of Europe as far as Greenland; Mr. Hutchins, 
according to Pennant, saw them commonly about Fort Albany, 
at Hudson’s Bay. Occasionally a pair is also seen in this 
vicinity in the depth of winter. They brave the coldest cli-

leave the Arctic regions ; the younger birds are commonly seen 
in the North of Germany, but very rarely the old, which are 
readily distinguished by the superior whiteness of their plumage, 
which augments with age, and by the increasing narrowness 
of the transverse stripes that ornament the upper parts of the 
body. The finest of these Falcons were caught in Iceland by 
means of baited nets. The bait was commonly a Ptarmigan, 
Pigeon, or common Fowl; and such was the velocity and 
power of his pounce that he commonly severed the head 
from the baited bird as nicely as if it had been done by a 
razor. These birds were reserved for the kings of Denmark, 
and from thence they were formerly transported into Ger- 
many, and even Turkey and Persia. The taste for the amuse-

and continued for several centuries; but at this time it has 
almost wholly subsided. The Tartars, and Asiatics gener- 
ally, were also equally addicted to this amusement. A Sir
