Prairie Ducks: A Study of Their Behavior, Ecology and Management

Clean, tight, unmarked; ffep cut out; back fep has a tape stain; price clipped; sunning to spine of dust jacket; 2cm closed tear to upper edge at spine edge that had been held with tape; bottom front of dj has creasing at inside edge; light edge wear to dj; otherwise very minimal wear; The success of duck hunters throughout much of North America each fall depends to a large degree upon the spring productivity of the breeding waterfowl in the northern prairie states and the central provinces of Canada.When Dr. Lyle K. Sowls began his studies at Delta in 1946, many wide gaps remained in the knowledge of the relationship of breeding ducks to their home range.As a result of Dr. Sowls' research, new light has been shed on such factors as predation, renesting, and homing habits of the important species of game ducks, and already have become the basis for revised hunting regulations and give a new understanding of waterfowl problems.
