5203 |a"The distribution, abundance and breeding chronology of waterfowl were measured from 1980 to1984 In central British Columbia. Eighteen species bred regularly in the area. Blue-winged Teal (Anasdiscors), Mallard (A. platyrhyncos) and American Wigeon (A. americana) were the dominant dabbling ducks, whereas Barrow's Goldeneye (Bucephala islandica), Bufflehead (B. albeola) and Lesser Scaup (Aythyaafflnls) were the dominant diving ducks. Because of the presence of migrants, waterfowl abundance varied signiflcantly throughout the spring with fluctuations often being abrupt and asynchronous among species"--Abstract.
