Main use of a rhinoceros horn
The main use is posturing but also for several behavioural functions, including defending territories, defending calves from other rhinos and predators, maternal care (including guiding calves) and foraging behaviour, such as digging for water and breaking branches.
Female rhinoceroses use their horns to steer their young and guide them until they are capable of navigating on their own. Male rhinoceros sometimes use their horns to move their excrement into piles that demarcate the border of their territory.
This rhino has not got a horn anymore and is from the Munich zoo.
