26o SWIMMERS. 



This is the most northerly in its range of the Jaegers, and has 

 the widest distribution. Its breeding area lies exclusively within 

 the Arctic Circle, and follows that line throughout its circuit. These 

 birds appear off the New England coasts during the spring and 

 fall, and at those seasons are common in the Bay of Fundy. As 

 they have not been seen near the shore farther to the southward, 

 they probably winter on mid-ocean. 



In its habits the Long-tailed Jaeger does not differ materially 

 from the other species.

The Cut-water, or Black Skimmer, is a bird of passage in 

 the United States, appearing in New Jersey from its tropical 

 winter quarters early in May. Here it resides, and breeds in 

 its favorite haunts along the low sand-bars and dry flats of the 

 strand, in the immediate vicinity of the ocean. The nests of 

 these birds have been found along the shores of Cape May 

 about the beginning of June, and consist of a mere hollow 

 scratched out in the sand, without the addition of any extrane- 

 ous materials. As the birds, like the Terns and Gulls, to which 

 they are allied, remain gregarious through the breeding-season, 

 it is possible to collect a half bushel or more of the eggs from 

 a single sand-bar within the compass of half an acre ; and 

 though not very palatable, they are still eaten by the inhabi- 

 tants of the coast. The female only sits on her nest during 

 the night or in wet and stormy weather ; but the young
