An afternoon with Dwarf Mongooses

These usually shy animals provided us with great entertainment during their social hour the other afternoon.

We waited patiently for them to become relaxed with our presence.

Behavioural Info



There is a strict hierarchy within a group, headed by a dominant pair. The dominant female is usually the leader of the group. All group members cooperate in helping to rear the pups and guarding the group from predators.

Dwarf mongooses are territorial. They sleep at night in disused termite mounds, although they occasionally use piles of stones, hollow trees, etc. Territories often overlap slightly, which can lead to confrontations between different groups.

Generally, only the group's dominant female becomes pregnant and she is responsible for 80% of the pups reared by the group. If conditions are good, subordinate females may also become pregnant but their pups rarely survive.

Normally one or more members of the group stay behind to babysit while the group goes foraging. At 4 weeks of age the pups begin accompanying the group.

A mutualistic relationship has evolved between Dwarf Mongooses and hornbills, in which hornbills seek out mongooses in order to forage together and warn each other of nearby birds of prey and other predators. Sometimes the hornbills can be seeing pestering the mongooses to get going in the morning, no time for a sunbathe!
