These data are difficult to interpret, inasmuch as it is apparent that the birds 
do not represent breeding populations along the shorelines where they were found, 
except possibly for the eiders. The number of most species except eider decrease 
practically to zero as the breeding season progresses, indicating that many of the 
birds may simply be waiting for more northern waters to open before moving out. 
Production Survey 
A survey to measure relative brood production was conducted for the first 
time during the summer of 1953. The dates of the survey were July 3 to 24. 
Although somewhat experimental in nature, 6, 300 miles of transect were flown. 
The sample was scattered throughout the region, except as limited by gasoline and 
adequate maps. 
As broods were observed under suitable conditions a record was made of the 
age class of the brood and the number of ducklings. Also, an attempt was made to 
determine the species. Of these data it was the opinion of the observers that only 
the information regarding the number.of broods, age class, and number of ducklings 
per brood were usable. These data are summarized in Tables IV and V. Species
