Dwarf Mongoose

The common dwarf mongoose is Africa's smallest member of the order Carnivora, with a body length of 16 to 23 cm and a weight of 213 to 341 g. Its soft fur ranges from yellowish red to very dark brown. It ranges from Eritrea and Ethiopia south to Limpopo and Mpumalanga in South Africa, in dry grassland, open forest and bushland, and is especially common where there are many termite mounds, its favourite sleeping place. Diurnal and social, packs average twelve animals and are organised around a single breeding pair, with younger members helping to care for juveniles. It eats mainly insects such as beetle larvae, termites and grasshoppers, along with spiders and scorpions.

About the dwarf mongoose

The dwarf mongoose, or common dwarf mongoose, is a tiny, highly social mongoose of East and southern Africa's dry grasslands and bushland. It is Africa's smallest member of the order Carnivora, related to the meerkat and other mongooses, and it lives in family packs ruled by a single breeding female and her mate.

Its scientific name is Helogale parvula. It shares the genus Helogale with one other species, the Ethiopian dwarf mongoose, which is its closest relative. Several subspecies are recognized across its wide range, and some, such as H. p. undulata of eastern Africa, are occasionally treated as separate species.

The size is the headline. The body measures just 16 to 23 cm (6.3 to 9.1 in), with a tail of about 14 to 19 cm (5.5 to 7.5 in), and the animal weighs 213 to 341 g (7.5 to 12.0 oz). Males and females look alike and are about the same size.

The soft, short fur ranges from yellowish red to very dark brown, and often looks speckled brown to greyish. Some animals are entirely black, and some have a reddish throat and chest. The tail and lower legs are usually darker, and the underside is slightly paler. The rounded head ends in a pointed snout, and the ears are small and rounded. Short legs end in five toes, and the claws on the front feet, up to 10 mm (0.4 in) long, are built for digging. Its 36 teeth are sharp and strong, and the cheek teeth have high cusps suited to crunching insects.

Behavior and diet

Dwarf mongooses are diurnal. The pack sleeps together at night in an underground burrow, a rock crevice, or, most often, a termite mound, which is their favorite sleeping place. They leave in the morning, often rest at midday, and return before sunset. Most of the day goes into searching for food among brush, leaves, and rocks, and a pack may travel up to about 1 km (0.6 mi) a day.

Packs average about twelve animals, though larger ones exceed thirty. Each is built around one breeding pair. The dominant female holds the top rank, sets the travel routes, and eats first, and her mate ranks second. Within each age class, females outrank males. The dominant pair are usually the only animals that breed, and the breeding male often stops other members from mating with a low-key threat posture. Pack life is mostly peaceful, with frequent mutual grooming and scent-marking, and there are reports of packs caring for a sick member.

While the group forages, one animal acts as a sentry. It climbs to a high point to watch for predators and calls out a warning when danger appears. Predators include raptors, marabou storks, snakes, monitor lizards, jackals, and Egyptian mongooses. Packs are territorial, defending ranges of about 0.3 to 1 km² (75 to 250 acres). When two groups meet, the smaller one usually backs off without a fight.

Dwarf mongooses also team up with hornbills. In eastern Africa, especially the subspecies H. p. undulata, they sometimes forage alongside Von der Decken's hornbill and the eastern yellow-billed hornbill. The birds catch insects, especially grasshoppers, that the mongooses flush out, and in return they warn the mongooses of birds of prey. The hornbills seek out the mongoose packs, the mongooses even wait for the hornbills before starting to forage, and both hornbill species use particular behaviors to signal that they are ready to team up.

The diet is mostly invertebrates: beetle larvae, termites, grasshoppers, crickets, millipedes, spiders, and scorpions. Secondary foods include small vertebrates such as small mammals, geckos, snakes, and birds, plus eggs and fruit. To open a bird's egg, a dwarf mongoose grips it in its front paws and flings it backward between its hind legs against a rock.

Breeding happens mostly in the wet season, from November to May. The dominant female can have up to three litters a year, averaging four pups each, after a gestation of about 49 to 56 days. Subordinate females rarely breed, and their litters seldom survive. Instead, younger members and newcomers act as babysitters, a role that rotates daily. They warm, guard, carry, and feed the pups, and subordinate females may even nurse them. Pups nurse for about 45 days and start foraging with the adults at about six weeks, when each pup attaches itself to an adult who guards and feeds it. Because of the social system, dwarf mongooses rarely breed before about three years old. Groups seldom split, usually only when the dominant female dies.

Range and habitat

The dwarf mongoose ranges widely across East and southern Africa. It is found from Eritrea, Ethiopia, and Somalia south to the Limpopo and Mpumalanga provinces of South Africa, and west to Angola, northern Namibia, and northern Botswana, including Zambia and KwaZulu-Natal.

It lives mainly in dry grassland, savanna, open forest, and bushland up to 2,000 m (6,600 ft). It is especially common where there are many termite mounds, and it avoids both dense forest and very dry desert.

Dwarf mongoose vs meerkat

The dwarf mongoose and the meerkat are both small, social mongooses whose non-breeding pack members help care for the dominant pair's pups, so they are easy to confuse. They differ in size, coat, and habitat.

Conservation status

The dwarf mongoose is listed as Least Concern on the IUCN Red List, based on a 2015 assessment. It is common and widespread, the overall population is considered stable, and no major threats are known.
