[26][27] Some subordinate meerkats will even kill the pups of dominant members in order to improve their own offspring's position. [40] Infants make continuous sounds that resemble bird-like tweets, that change to a shrill contact call as they grow older. [51] Meerkat Manor (2005–2008), a television programme produced by Oxford Scientific Films that was aired on Animal Planet, focused on groups of meerkats in the Kalahari that were being studied in the Kalahari Meerkat Project. He will grip the nape of her neck if she resists mounting, and hold her down by grasping her flanks during copulation.

Vocalizations play a key role in the coordination of movement in many social species, particularly those that form stable social groups. Females have six nipples. Cape ground squirrels and meerkats usually do not fight for space or food. They were by far the most active meerkat group we had seen, possibly due to the group’s size and general personality or the pups’ eagerness to eat and explore. It is characterised by a broad head, large eyes, a pointed snout, long legs, a thin tapering tail, and a brindled coat pattern. The name was used for small mammals in South Africa from 1801 onward, possibly because the Dutch colonialists used the name in reference to many burrowing animals. Photography just keeps getting better!!! What does a foraging meerkat sound like? This association is beneficial to all the species as it saves time and efforts spent in making separate warrens. This contrast of different groups reveals a social complexity that is only found in a few social mammal species. A popular example is Timon from the Lion King franchise, who is an anthropomorphic meerkat. It is absent from true deserts, montane regions and forests. Breeding occurs round the year, with peaks during heavy rainfall; after a gestation of 60 to 70 days a litter of three to seven pups is born. Generally only dominant individuals breed, though subordinate members can also mate in highly productive years. Moreover, meerkats have more call types than do banded mongooses. [29][21] Dispersal appears to be less common in females, possibly because continuing to stay with in a pack can eventually win them dominance over other members. Thank you for sharing, Zander!! For other uses, see, "Meerkats" redirects here. 'Boltholes' are used for a quick escape if dangers are detected. [49], Meerkats are generally tame animals. Members of a pack take turns at jobs such as looking after pups and keeping a lookout for predators. The marker type indicates the type of call - see legend for details. [11], The meerkat has a specialised thermoregulation system that helps it survive in its harsh desert habitat. Meerkats are widely depicted in television, movies and other media. They hunt by scent, and often dig out soil or turn over stones to uncover hidden prey. [2], Meerkats have been widely portrayed in movies, television and other media. [41] Sex biases have been observed in feeding; for instance, female helpers feed female pups more than male pups unlike male helpers who feed both equally. [28] It can take days for emigrants to secure entry into other packs, and they often face aversion from the members. There is a social hierarchy—generally dominant individuals in a pack breed and produce offspring, and the nonbreeding, subordinate members provide altruistic care to the pups. Dominant females can have up to four litters annually (lesser for subordinate females), and the number depends on the amount of precipitation. Many other species have also been recorded in the meerkat burrows, including African pygmy mice, Cape grey mongooses, four-striped grass mice, Highveld gerbils, rock hyraxes, slender mongooses, South African springhares and white-tailed rats. In colloquial Afrikaans mier means 'termite' and kat means 'cat', hence the name probably refers to the meerkat's association with termite mounds. Young pups are kept securely in a den, from where they emerge after around 16 days, and start foraging with adults by 26 days. Mating behaviour has been studied in captive individuals. Subordinate females, unlike subordinate males, might be ousted from their packs, especially in the latter part of the dominant female's pregnancy, though they may be allowed to return after the birth of the pups. Some individuals stand sentry while the rest are busy foraging. [11] The Kalahari Meerkat Project, founded by Tim Clutton-Brock, is a long-term research project run by four different research groups that aims focuses on understanding cooperative behaviour in meerkats. But the snake?! [8] The generic name Suricata was proposed by Anselme Gaëtan Desmarest in 1804, who also described a zoological specimen from the Cape of Good Hope. In fact, even the show “Meerkat Manor,” which highlighted a few meerkat groups and their daily lives, was filmed on the site. [11], The meerkat has 36 teeth with the dental formula of 3.1.3.23.1.3.2. The sharp, curved foreclaws are adapted for digging. [48], The meerkat occurs in southwestern Botswana, western and southern Namibia, northern and western South Africa; the range barely extends into southwestern Angola. A golden brown head popped out and did a quick survey of her surroundings. Your Meerkat friends seem to love to pose with you! The head-and-body length is around 24–35 cm (9.4–13.8 in), and the weight is typically between 0.62 and 0.97 kg (1.4 and 2.1 lb). The meerkat gives 4 close calls during the clip, which are marked with dotted lines in the corresponding waveform and spectogram image. [21], Outside temperatures are not reflected at once within burrows; instead there is usually an eight-hour lag which creates a temperature gradient in warrens, so that burrows are coolest in daytime and warmest at night. It was founded by Tim Clutton-Brock, an animal ecology professor at Cambridge University, and is run by a variety of scientists and volunteers, who are working to understand the meerkat’s unsolved mysteries. Many often team up in 'coalitions' for as long as two months and travel nearly 5 km (3.1 mi) a day on twisted paths. Note the banded pattern, the big eye circles and the thin tail. During winter, it balances heat loss by increasing the metabolic heat generation and other methods such as sunbathing. The Initial Task: Finding the Meerkats – The sun had not even shown its first rays as some elands and a herd of springbok grazed in the dim light of dusk. Published in Proceedings of the Royal Society B, this is the first empirical study to reveal intergroup aggression. This reduces the need for meerkats to thermoregulate individually by providing a comfortable microclimate within burrows; moreover burrowing protects meerkats in harsh weather and at extreme temperatures. Meerkat clans perform a ‘war dance’ to frighten opponents and protect their territory, according to a new UCL and University of Cambridge study. Meerkats return to an area only after a week of the last visit so that the food supply is replenished sufficiently. [2][6][7], In 1776, Johann Christian Daniel von Schreber described a meerkat from the Cape of Good Hope, giving it the scientific name Viverra suricatta. [39] Meerkats often eat citron melons and dig out roots and tubers for their water content. Data were collected from January to March 2015 on eight groups, ranging from 9 to 22 individuals (mean ± s.d. [21] Meerkats are estimated to survive for five to 15 years in the wild; the maximum lifespan recorded in captivity is 20.6 years. Meerkats occur in several protected areas such as the Kgalagadi Transfrontier Park and the Makgadikgadi National Park. Its head is mostly white and the underparts are covered sparsely with dark reddish brown fur, with the dark skin underneath showing through. Commonly found in arid, open habitats with little woody vegetation, meerkats occur in southwestern Botswana, western and southern Namibia, northern and western South Africa; the range barely extends into southwestern Angola. The meerkats have gotten used to the weight scale and receiving eggs as a reward, and some of them have become extremely comfortable around humans. = 16 ± 4) during the morning foraging session. Looking forward to seeing what’s next!!! They stick their heads out of burrows to check the area outside, still barking. After these brief, minute-long interactions, both meerkat groups united as they continued foraging for the rest of the morning. For the 2008 British film, see, "Suricata" redirects here. 'Alarm calls' are given out on detecting predators. [31] Short-range 'close calls' are produced while foraging and after scanning the vicinity for predators. [45] The mother runs around with prey in her mouth, prompting her pups to catch it. All these calls differ in their acoustic characteristics, and can evoke different responses in the 'receivers' (meerkats who hear the call); generally the greater the urgency of the scenario in which the call is given, the stronger is the response in the receivers. The burrow systems, typically 5 m (16 ft) in diameter with around 15 openings, are large underground networks consisting of two to three levels of tunnels. After several minutes, the whole group had looked out and began to completely exit their sleeping quarters. Though yellow mongooses are also insectivores like meerkats, competition for prey is minimal as yellow mongooses are less selective in their diet. The meerkat belongs to the monophyletic eusocial mongoose clade along with several other African mongooses: Crossarchus (kusimanse), Helogale (dwarf mongoose), Liberiictis (Liberian mongoose) and Mungos (banded mongoose). [11][21], After a gestation of 60 to 70 days, a litter of three to seven pups is born. It began in the Gemsbok National Park (now part of Kgalagadi Transfrontier Park) but was shifted to the Kuruman River Reserve in 1993. Mobs of meerkats fiercely attack snakes that may come near them, often killing a few. Video shows one hour of combined movement and acoustic data for all seven meerkats within the "Hakuna Matata" group, from 10 - 11 am on August 25, 2017 in the Kalahari Desert, South Africa. The Range of Groups – Experiences like these twice a day for four days offered a unique insight into this extraordinary project. For the study, data was collected between January 2008 and February 2019 as part of a long-term behavioural study of wild meerkats in the Kalahari Meerkat Project, South Africa. They suggested there were four local meerkat races in the Cape and Deelfontein, Grahamstown, Orange River Colony and southern Transvaal, and Klipfontein respectively. This is powerful and inspiring work you are doing. Males typically succeed in joining existing groups; they often inspect other packs and their burrow systems in search of breeding opportunities. [21] Dispersed females travel longer than coalitions, and tend to start groups of their own or join other similar females; they aim for groups of emigrant males or those without a breeding female. [11], Meerkats breed throughout the year with seasonal peaks, typically during months of heavy rainfall; for instance, maximum births occur from January to March in the southern Kalahari. [42] Sometimes helpers favour their own needs over those of pups and decide not to feed them; this behaviour, known as "false-feeding", is more common when the prey is more valued by the meerkat. Telemetry, a form of radio tracking that sends radio signals between a collar or tag to a transmitter, was the only way to look for these animals because no one had watched them disappear into a burrow the night before. Individuals from the southern part of the range tend to be darker. This is possibly because the survival of female pups is more beneficial to female helpers as females are more likely to remain in their natal pack.
