536 ORNITHOLOGY AND OOLOGY. 



Length, thirty-three inches ; wing, thirteen ; tail, six and seventy-five one-bun- 

 dredths inches. 



Hob. Atlantic coast from Labrador to Carolina; for countries; Pacific coast 

 from Washington Territory to California. 



This species resorts in large numbers to the low islands off the coast of Labrador, 

 which are the i breeding stations : they construct their nests on the surface of the 

 rocks, not on the shelves of precipices. 



I once witnessed a large migrating flight of these birds to the South, along our 

 seacoast. They passed in great flocks, which succeeded each other frequently during 

 the entire day : each flock formed a widely extended front, the individuals being 

 side by side. Their mode of flight was by alternate flapping of the wings, and their 

 sailing for a short distance, the effect of which was peculiar and striking. GEORGE

I think that this species is more northern in its habits 

 than the preceding, as it is seldom seen on the coast of New 

 England except in the winter months, and then only in 

 small numbers. Unlike the preceding, it does not breed 

 south of the coast of Labrador ; and, in nesting, does not 

 frequent high precipices, but prefers low rocky islands. The 

 nest is similar to that of the other : and the eggs, although 

 averaging smaller, are hardly recognizable from those of 

 the Common Cormorant; an ordinary large one of the 

 present being of similar form and size with the other.
