Like all animals in the game, ducks can be hunted for sport or for profit. They can be heard quacking while flying and can be easily identified while airborne from other birds by their plump bodies, long necks and their constant and consistent need to flap their wings rapidly while flying. The best time to find ducks is during clear skies from about noon to sunset while the hardest time to find ducks is during storms, however, they can occasionally be found at night.
These locations are where you will have the best chance of spotting ducks, though they can be found near most large bodies of water:
- Near Lake Don Julio (the best spot to find ducks)
- Rio del Toro
- The river north of the Great Plains.
- Near The Old Bacchus Place.
- Flying over Thieves' Landing.
- Near the Wreck of the Serendipity.
