About the middle of May this dainty Httle Gull arrives in 

 small flocks, and for a week or two enlivens the shores of the 

 Bay with its airy gambols, but soon passes on farther north to 

 its breeding grounds. In the fall it returns, subdued in dress

 to be close enough for observation. In spring, when at liberty 

 to move about, they visit Hamilton Bay in small numbers, and 

 are seen fishing, about the mouths of the inlets or more frequent-
