 A more detailed discussion of the categories of data recorded is 



Two sets of field maps were used for recording ground and aerial routes, and 

 the locations of animals observed. Maps of the reconnaissance level study area 

 (scale 1:125,000) were available throughout the report period. Observations made 

 in the mine study area were recorded on topographic maps (scale 1:12,000) after 

 March of 1977. At the end of each month, locations of observations were trans- 

 ferred by hand to base maps by species or groups of species for analysis of dis- 

 tribution patterns. 



All observations of waterfowl were recorded on a similar data sheet (Appen- 

 dix C). Data recorded for each observation included level (as above), date, 

 observers, time, location and description of water area, species of waterfowl, 

 activity, number of birds by sex and age, number of obvious pairs, brood size, 

 and number of nests. It was also indicated on these sheets whether or not a cen- 

 sus of the water area was taken, and whether or not an active search for nests 

 was made. The methods of Ellig (1955) were applied, with modification, to nest 

 searches, and Stewart and Kantrud's (1973) modification of the criteria used by 

 Hammond (1969:247-248) were used to determine the indicated number of breeding^^ 

 pairs present based on segregated pairs, lone males, mixed groups, "excess" 

 lone females, and certain male groups. These data provide information useful
