 gulls in winter is at the mouths of our larger 

 rivers, like the Hudson, which are always 

 utilized for seaports, and whose shipping affords 

 variety and abundance of food. 



In plumage there is a strong family resem-

 them are, like the herring gull, overspread 

 with a beautiful pearly-blue mantle, as delicate
