Ducks are birds which can commonly found in rivers or lakes. They are very small, and are most often found on water, meaning they drop nothing, but if killed on land, they will drop bones. They are often found in the company of ducklings and drakes.
Aside from using halberds, players can usually only range or mage them. Ranging ducks will cause players to lose ammunition unless they use a chargebow. Because of this, using Ranged to kill ducks is a method that is rarely used by most players.
If the duck is next to the shore, the player can hit it with a melee weapon, but this occurrence is rare. Ducks found on land, such as those in Falador Park, can be killed easily with any weapon.
