 the lagoons and coves which transect the woods (Plate II) 

 are former channels of this stream. By the building of a 

 road (North Cayuga Street) and the consequent damming of 

 lateral tributaries from the hill toward the east, processes hke 

 those described for the western part of the marsh have been 

 at work, resulting similarly in dead trees and patches of open 

 marsh.

 belongs to the Transition Zone, with a stronger admixture of 

 the southern than of the northern elements. Of the 22 birds 

 listed by him as finding the northern Hmit of their breeding 

 range in the Transition Zone, 15 have been found breeding in 

 or about the marsh:
