PROCELLARIIDA: SHEARWATERS AND PETRELS 
Ocean wanderers, common in summer off the New England coast 
some miles from land; the Shearwaters are rather large birds, 
about the size of a small Herring Gull; they are to be seen 
flying about the boat with their wings set at right angles with 
their body, not curved downwards like the gulls. The Petrels are 
tiny birds, seen at the stern following the wake of the boat, 
they look like white-rumped swallows; they are often called 
Stormy Petrels and Mother Carey's Chickens, but Procellaria 
pelagica, a.smaller species inhabiting the east side of the Atlantic, 
is the true Stormy Petrel. The males and females are alike.
