NB - This table represents total aerial observations made on comparable 
areas for 1952 and 1953. Time does not permit a full break-down 
into numbers per unit area in all types of habitat covered, particularly 
in the larger marsh areas such as Hampton (fresh), Musquash (salt), 
in New Brunswick and Yarmouth County (salt) in Nova Scotia where 
total coverages were made. Where a break-down has been possible 
results are shown in Table ITI.

* Adults include all birds not definitely identified as broods, also include the 
females accompanying broods, Broods refer to numbers of broods seen, Because 
many complete broods were not seen the number of ducklings was not integrated into 
the population figures. Number of ducklings may be computed from the table on 
average brood sizes.
