CORY SHEARWATER 
88. Puffinus borealis. 21 in. 
This rare bird is found off the coast of New England 
and in Long Island Sound from July to September. It 
is slightly larger than the similar Greater Shearwater, 
the back and head are lighter in color, the entire under- 
parts are white, and the bill is yellowish. Its nesting 
habits and eggs are unknown, but they are supposed to 
breed in the Antarctic regions. 
The majority of specimens that have been taken have 
been found off Chatham, Mass. 
AUDUBON SHEARWATER 
92. Puffinus lherminieri. 12 in. 
This small shearwater, except in point of size, is quite 
similar to the following, but the under parts are white, 
except the under tail coverts which are sooty; the back 
and head are somewhat lighter too. They nest in abun- 
dance on some of the Bahaman and West Indian Isiands, 
and can usually be met with off the South Atlantic 
coast in summer. 1 
Their eggs, which are pure white (2.00x 1.35), are 
deposited at the end of burrows dug by the birds.
