Produktbeschreibung
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. There were many scattered observations and a growing mass of data accumulated through the study of banding returned; but the activities of individual ducks during the critical spring months and the activities and the fate of broods each summer remained largely a mystery. Sowls, working toward his doctorate in wildlife management as a graduate student of the University of Wisconsin, studied the waterfowl at Delta for five years in an attempt to plug some of those gaps through intensive study of the waterfowl on one limited are. His studies developed new techniques and brought out new facts that were startling even to waterfowl biologists, facts of prime importance to the duck hunter or to any one interest in the future of America's waterfowl flights. 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.

Autorenporträt
When Dr Sowls began his long studies of the Delta Waterfowl Research Station in Manitoba, little was known of the activities of individual birds on these vital breeding grounds. The studies brought out new facts that were startling to wildlife scientists and of importance to the duck hunter. Material recorded in this book has become the basis for revised hunting regulations and gives new understanding to waterfowl problems.
