AUDUBON'S SHEARWATER.

 sooty flanks and under tail coverts. 

 L., 12.00. 



Range — Breeds in the Antilles 

 and Bahamas. Wanders north cas- 

 ually to Long Island. 



rare, less is known about their habitat than of nearly any 

 other bird. Small numbers appear off the coast of Mas- 

 sachusetts and in Long Island Sound every summer. They 

 have been taken in no other place. Their habits while 

 with us are not different from those of the more common 

 species. I have seen them in groups of from two to six 

 individuals and also with Greater Shearwaters. 



GREATER SHEARWATERS are abundant off the At- 

 lantic coast from June until October. They rarely, if ever, 

 alight upon our shores and seldom come within several 

 miles of land. They spend the day wandering over the 

 ocean searching for dead fish or other refuse matter and 

 sleep on the water wherever night may overtake them. 

 While their exact breeding grounds are unknowm, they 

 undoubtedly nest during January and February on islands 

 in southern seas.
