the first, the first with a white spot near the end, the second with a small

Distinctive marks. This bird can scarcely be mistaken for any other 

 of OUT gulls, except the Herring gull, but I am inclined to think this often 

 occurs, as comparatively few reports of this sj^ecies have been received 

 from amateur observers throughout the State. This bird is 5 inches shorter 

 than the Herring gull. The old birds also may be distinguished by the 

 black ring on the bill, the greenish yellow legs, and the black tip of the first 

 primary; and young birds by the size, and the broad band on the tail. 



Distribution. This is a species of the boreal and arctic zones, breeding 

 mostly in the interior of British America. According to Giraud and Dutcher 

 it is a common winter visitant on the shores of Long Island. Dr Braislin 

 calls it a regular transient visitant, rare in winter and summer. It is given 

 as an occasional winter visitant in the Hudson Highlands, by Meams; at 

 Ossining, by Fisher; and in western New York, by Short. The Auburn 

 List gives it as a rare visitant. It has been recorded from Cayuga, Erie, 

 Essex, Monroe, Niagara, Oneida, Ontario, Orleans, Oswego, Onondaga, 

 Seneca, Schuyler, Tioga, Westchester and Yates counties, but in nearly 

 every instance was called a rare transient visitant. On Canandaigua and 

 S?neca lakes I have found it decidedly less common than the Hen-ing and 

 Bonaparte gulls, but on Lake Ontario and the Erie canal it is sometimes 

 fairh' abtmdant as a spring migrant. The record of its nesting at .Axton in
