species are known to inhabit North America, four of which, vizv 

 L. Rossii, Franklinii, ebernijs, and minutus, inhabit the high nor- 

 thern latitudes. L. occidentalis is a denizen of the western side of 

 the continent. Eight species are entitled to a place among " The 

 Birds of Long Island ;" and according to Mr. Audubon, L. leucop- 

 ■terus, ranges during winter from New York to Nova Scotia, but in 

 our locality I have not met with it. 



The Herring Gull is quite a common species, and is found along 

 the whole extent of the Atlantic coast. I have also observed it on 

 Lakes Ontario, Erie, Huron, and Michigan, and have met with it 

 on streams in the interior. At low water, with other species, it re- 

 sorts to the bars and shoals, sometimes congregating in such large 

 numbers, as to line the shore for a considerable distance. At the 

 influx of the tide, it passes most of its time in the air, flying around 

 in wide circles, and at times to a very great height. At other times 

 it is observed following the shoals of fry, on which it depends for 

 the greater portion of its support. As is the case with the rest of 

 this class of birds, it is incapable of diving, and can only secure its 

 prey when at the surface, immersing only the head and neck.
