88. Cory's Shearwater. Puffinus borealis. 



This species probably breeds in the far south. 

 It has been found only off the coast of Massa- 

 chusetts and Long Island. This is the largest 

 of our Shearwaters, and can be distinguished from 

 the next species by its wholly white underparts, 

 its light mantle and yellowish bill. We have no 

 data relative to its nesting habits. 



89. Greater Shearwater. Puffinus gravis. 



Range. — The whole of the Atlantic Ocean. 



Thousands of them spend the latter part of the 

 summer off the New England coast, where they 

 are known to the fishermen as Haglets. Their 

 upper parts are brownish gray, darker on the 

 wings; bill and feet dark; under parts white, with 

 the middle of the belly and the under tail cov- 

 ers dusky. Length about 20 inches. Little is 

 known concerning their nesting quarters, al- 

 though they are said to breed in Greenland. 

 From the fact of their early appearance off the 

 New England coast it is probable that the great- 

 er part of them nest in the far south. 



[{)<>.] Manx Shearwater. Puffinus puffinus. 



This species inhabits the North Atlantic ocean 

 chiefly on the European side, being abundant in 

 the Mediterranean and in the British Isles. These 

 birds deposit their single pure white eggs in
