TextSeries: Thesis. (M.A.)Publication details: Saskatoon, SK : University of Saskatchewan, 1966.Abstract: Knowledge of the direction, distance and rate of dispersal of North American waterfowl is of considerable importance in the study of their behaviour and ecology. The determination of mortality is a pre-requisite to an understanding of their population dynamics. The purpose of the present study was to determine the distribution and mortality characteristics of adult male pintails moulting on a marsh near the heart of the breeding range of the species in North America. In North America in the early part of this century, bird-banding activities grew rapidly. The American Bird-Banding Association, a private organization,was formed in New York City in 1909 to serve as a center for processing the growing volume of records. In 1920 the U.S. Bureau of Biological Survey (the present U.S. Fish and Wildlfie Service) assumed responsibility for this work (Rustad, 1959).
