THE WINDHOVER HAWK. 261

 to the greatest advantage during the time that it 

 is occupied in rearing its young ; at that period, 

 nothing throughout the whole range of ornitholo-

 evolutions. 



Perhaps it is not generally known, that the wind-

 part of these hawks leave England in the autumn, 

 or merely retire from their breeding-place to some 

 other part of our country, more congenial to their

 nature in the fields may observe them, now on 

 soaring wing, high above in the blue expanse of 

 heaven ; now hovering near the earth, ready to
