‘© arundinaceus, BECHSTEIN. 
Circus—The Greek name of some species of Hawk. 
Rufus—Red. 
Wuy the birds of the genus at which we have now arrived 
should be called Harriers more than any others of the Hawk 
family, I know not. Yarrell suggests that the origin of the 
name has probably been derived from their beating the ground 
somewhat in the manner of a dog hunting for game. Their 
natural order is certainly in close proximity to the Owls; the 
most remarkable ‘feature’ of similarity being the ruff-like circle 
of feathers round the face, somewhat after the fashion of 
what in the human subject is called a calf-lick, and which is 
set up or depressed by the voluntary action of the bird. 
These Harriers are found in the temperate regions of three, 
if not four quarters of the globe. They are common in Norway 
and Sweden, Denmark and the south of Russia, Germany, 
France, Italy, Spain, Holland, and Turkey; less frequently in 
Switzerland, and the south of Europe: in Egypt, and other 
parts of Africa; the Himalaya Mountains, Asia Minor, and other 
districts of Asia. Wilson and Buonaparte consider this species 
to be the same as the American one they describe by the name 
of the Marsh Hawk, but several distinctive marks, as for 
example the difference in the length of the tail beyond the 
wings, will appear on reading their account, though they are 
right in overruling the erroneous reason given by Pennant, 
namely, the thickness of the legs, for supposing the birds 
distinct; whether, therefore, our species is found in America, 
I am not able to say.
