/ Birds of the marshes 



In the extensive marshes of the State several different zones 

 of vegetation can be recognized, from the open w^ater of the 

 ponds to the dry uplands : first, a fringe of bullrushes and v^^ater 

 lilies ; second, a growth of cat-tails where the substratum is 

 drier ; third, an area of sedges ; and fourth, fringing the dry land, 

 an area of marsh grasses. About the marsh there is usually a 

 fringe of willows, alders and button bushes. The birds of the 

 marshes are not limited in their movements to any one area but 

 the majority show a preference in selecting their nesting site. 

 The red-winged blackbird is the most adaptable of all the species 

 and is found nesting in all zones from the alders to the cat-tails.
