Summer Banding Operations - South Dakota, 1950 
Due to the lateness of the hatch and the importance of obtaining as much 
brood data as possible, banding operations were delayed until August 14. Although 
numerous broods were caught which were too small to band, most of the ducks of the 
year had reached flying age. Weather conditions made the period of August 14 to 25 
a miserable time in which to band ducks.. Results are included in the following table:
