American Wigeon (Anas americana) Science Article 1
abstract
Mallards (Anas platyrhynchos) and American Wigeon (A. americana) were studied in Alabama from November through February 1983-85. Resting was the major activity of Mallards (39-54%) and feeding was the major activity of American Wigeon (45- 7 1%). Mallards increased feeding during the colder winter of 1983-84, but wigeon did not. Locomotion (8-21% and 5-26%) and comfort (4-22% and 4-13%) also were dominant behavioral activities of Mallards and American Wigeon, respectively. Total time spent in alert, courtship, and agonistic behavior was low for both species (< 11%). Mallards and wigeon rested most on river sites, while managed impoundments were used most for feeding and social activity. Received 18 July 1986, accepted 27 Feb. 1987
