Sooty shearwater. Pt:ffinus griseus Strickland. From specimen in American Museum of Natural 



History, f nat. size 



The Sooty shearwater, or Black hagdon, appears off our coast in sum- 

 mer associated with the Greater and Cory shearwaters, but is less common 

 than P u f f i n u s major with which it agrees in habits. At a distance, 

 according to Brewster, "it looks as black as a crow," and hence can easily 

 be distinguished from the other species. This l)ird is now regarded the 

 same as the Old World species, but for years was held to be distinct.
