Passell, John 0. III. I969 -1971* Systematic bird censuses of North River marsh 

 (plus additional censuses to 1979) unpublished. 



FAUNA SPECIES LIST 

 Birds that occur regularly in the North River marshes: 



1. This list includes birds that occur (feed in or over the marsh) regularly in 

 the marsh proper. Birds of the adjacent open estuary, adjacent wooded areas, and 

 rarities not sighted every year are excluded from the list. 



2, For bre vity, status listed is a short approximation. Water birds often do 

 not fit well into a transient-summer resident; winter resident-permatent resident 

 grouping . 



3' List is based primarily on over two years (1969-1971) of systematic censuses 

 of the marsh conducted at approximately three week intervals at all s.jasons, 

 plus numerous additional censuses to 1979*
