Species Composition 
The six main species of breeding ducks on the Chippewa National Forest 
area have been the mallard, baldpate, goldeneye, ringneck, blue-winged teal and 
wood duck. Table II illustrates the species composition encountered since the 
inception of the census.

The species composition for 1955 gives a fairly true picture for all 
Species except Blue-winged teal which will be materially increased by the number 
of mated pairs and the goldeneyes which were observed earlier but absent during 
the census period. 
Brood Averages 
Table IIL illustrates brood averages for the mallard duck for each year 
since 1937. The brood average of Class [II mallards for the total survey area 
was 7,0 comparable to the 6.9 all time average.
