Mallards(Anas platyrhynchos) and Green-Winged Teal(anas crecca) were studied at Kum River, Kongju, Korea, from 29, December, 1990 to 5, Janury, 1991. There was a wide difference between Mallards(Anas platyrhynchos) and Green-Winged Teal(Anas crecca) in body length but used to same Resting or Feeding area.
Resting time was the major activity of mallards(43-45%) and Feeding time was the major activity of Green-Winged Teal(30-34%).
Both species increased Resting time as approach of sunset but Locomotion and Comfort decreased.
Locomotion(22-24% and 16-24%) and Comfort(16-21% and 14-22%) also were dominant behavioral activities of Mallards and Green-Winged Teal, respectively. Total time spent in Alert, Courtship and Agnoistics behavior was low for both species(>3%).
Mallards and Green-Winged Teal rested most on sand bar in River side, while paddy fields were used most for feeding area.
