6. Waterfowl Inventory F. C. Bellrose 
Five complete coverages were made of the waterfowl census area during [larch. 
In addition, three censuses were started but were not completed because of poor 
visibility. 
Snow and ice-covered waters slowed the northward movement of waterfowl until 
March 17. A tremendous surge of tardy northbound ducks occurred from [.larch 17 to 23. 
During that period, 18 species of ducks, from the early migrating pintail to the 
late migrating blue-winged teal, moved into the northern part of the state. 
A second but somewhat smaller influx of migrating ducks occurred on March 28 
and 29. This "wave" of migrants consisted largely of mallards, green-winged and 
blue-winged teals, widgeons, shovellers, and lesser scaups.
