OUR recent knowledge of this, the largest of American Gulls, rests so 

 far as this state is concerned, upon the statement of Mr. E. W. Vickers, who 

 reports "one found dead floating among ice in the creek near Canton" ;^ 

 and that of Rev. W. F. Henninger, who says :^ "On March 21, 1900, while 

 out duck-hunting I observed one specimen of this superb species. While 

 lying in a thicket on a small peninsula surrounded by the two arms of the Scioto 

 River and a slough on three sides, a large Gull alighted on the gravelly bank 

 of the river opposite me. Tho the bird was out of gun-shot range, with my 

 field glass I could easily tell the species. After staying there for about three 

 minutes, it raised its wing and soared majestically away, reminding one of 

 the Eagle's flight." 



The Great Black-backed Gull is a common species of the North Atlantic. 

 It is said to prey boldly upon the eggs and young of other species, and to 

 attack the smaller mammals of the Labrador Coast, altho its principal diet is 

 fish. It is at all times exceedingly wary, and in fair weather delights to soar 

 at great heights.
