The common Gull, both of coast and interior, seen in 

 great flocks about the beaches, and on the flats and sand bars 

 at low water. From middle autumn until the birds in 

 general are returning in the spring, these Gulls enliven the 

 solitude of the shore with their chatter, and their shrilly 

 high-keyed voices can be heard above the waves and storm. 



Beside being beautifully plumed and decidedly picturesque 

 objects in the marine picture, they have an economic value 

 which appeals even to the most unsentimental minds. They 

 are excellent scavengers, taking from creeks, bays, and 

 rivers, as well as from the lakes and open sea, much refuse 

 that becomes unsavoury if washed ashore and left to decom- 

 pose. 



liaughing Gull: Larus atricilla. 



Length : 16.50 inches. 



Male and Female: Head and neck dark slate; bill carmine. Back 



slate-colour, divided from the head by the white of the neck. 



All under parts white ; also tail coverts. Legs and feet dull 



reddish. Young, upper parts gray tinted with various browns,
