Drakes may kill ducks during mating season due to territorial behavior or competition for mates. If a drake perceives a threat to its dominance or breeding rights, it may resort to aggressive actions, including attacking and killing other ducks. Additionally, if resources are scarce or if the drakes are trying to establish their own breeding territory, this behavior can be exacerbated. Such aggression can severely impact local duck populations, especially if the drakes outnumber the females.
