Cormorant. Phalacrocorax carbo 



36.00 



Ad. — Black, with a white throat. Im. — Belly whitish. 



The Cormorant is an uncommon migrant along the coast, and 



a winter visitant from Cormorant Rocks in Narragansett Bay 



and the ledges off Cape Ann to the outer islands of the Maine 



coast, where it is not uncommon. 



It may be distinguished from the Double-crested Cormorant 

 (p. 310) by its larger size and in the adult plumage by its white 

 throat. In the immature plumage, commonly seen in winter, 

 the Cormorant has a whitish belly, while the belly of the smaller 

 species is brownish.
