The falco lineatus.

1815.  A very large flock of Hen-hawks and white-headed Eagles.—Mass. Spy, Oct. 11.

1821.  Birds of prey in this country are of many kinds; yet, if we except the Common or Hen-hawk, are few in number. It is a remarkable fact that the King-Bird or Bee-eater, is an over-match for any of them.—T. Dwight, ‘Travels,’ i. 53.

1854.  

            Dimly I catch the throb of distant flails;
    Silently overhead the hen-hawk sails,
With watchful, measuring eye, and for his quarry waits.
J. R. Lowell, ‘An Indian-Summer Reverie.’
