Table V gives the sex composition of 1,068 ducklings handled in banding 
operations in the eastern sandhills. All but fourteen of these were of the local 
age group, mostly Class II and Class III. The banding was done with drive traps 
or by driving from the ponds and capturing them by hand, hence no sex-selectivity 
was shown.

Summary 
Though weather and water conditions were not at optimum, a large breeding 
population and good success showed a substantial increase in production in the 
Nebraska sandhills. Advanced phenology may have biased the count some but the 
blue-winged teal shows up as the number one nester in Nebraska with 61 percent 
of the broods.
