The BARNACLE GOOSE (!?'>. /!ni/,t<t /,'/,/>.//> is an Old- World species 

 which visits Greenland regularly in the lull, and is sometimes found mi our 

 coast*. It differs from any of the preceding in having the forehead, sides of 

 the head, throat, and chin white, the lores being black. 



Subfamily Cygninc?. Swnnx. 



Swans feed from the surface, either by "tipping" or by simply 

 immersing tin- long neck and head. Their food consists largely of 

 vegetable matter, but they eat also small inollnsks. They migrate in 

 V-shaped ilorks. When on the wing, and also when feeding, they utter 

 at times loud, trumpeting notes. When pursued they do not at once 

 take flight, but swim rapidly away, and in tins manner easily distance 

 a strong rower.

This is a rare bird on the Atlantic coast north of Virginia. " When 

 feeding, or dressing their plumage, this Swan is usually very noisy, 

 and at night these clamors may be heard to the distance of several 

 miles. Their notes are varied, some resembling the lower ones made 

 by the common tin horn, others running through the various modula- 

 tions of the notes of the clarionet. These differences are presumed to 

 be dependent upon age " (B., B., and H.).
