The birds ride the water buoyantly, but do not dive, only im- 

 mersing the head and neck. In their food habits omnivorous, 

 greedy eaters; scavengers of the beach, and in the harbors to 

 be seen boldly alighting upon the masts, and flying about the 

 vessels; picking up the refuse matter as it is cast overboard, 

 and often following the steamers from thirty to forty miles from 

 the land, and occasionally much farther. They are ever upon 

 the alert, with a quick eye that notices every falling object, or 

 disturbance of the water; and as they herald with screams the 

 appearance of the herring, or other small fishes that often swim 

 in schools at the surface of the water, they prove an unerring 

 pilot to the fishermen, who hastily follow with their lines and 

 nets; for they know that beneath, and following the valuable 

 catch in sight, are the larger fishes that are so intent upon tak- 

 ing the little ones in out of the wet as largely to forget their 

 cunning, and thus make their capture an easy one. 



The birds are abundant on the Atlantic coast, decreasing in 

 numbers west, and I think rare on the Pacific coast. I have 

 collected three winters along that coast, and during the time did 

 not meet with a single bird.
