Production Data 
(a) Black Duck 
Brood averages are very close to the 1957 averages (Table 3). 
However, the high young to adult ratio (Table 2), and the large number of 
Class III broods observed on the survey suggests that production, in 1958 
will exceed both 1957 and 1956 production. 
(b) Ring-necked Duck 
aS se 
{ 
Thirteen broods of this species’ were observed on the transects 
this year as compared to two broods in 1957. Although the number of birds 
observed is small, our data suggest an increase in production from 1957. 
(c) Others 
The available data suggest that there will Be no appreciable 
changes from 1957 in the production of Goldeneye, Blue- and Green- winged 
Teal and Pintail.
