Geographic Range
Mellivora capensis
, the honey badger or ratel, has an expansive geographic range, spanning most of sub-Saharan
Africa as well as the Arabian peninsula (including portions of Israel, Jordan, Iraq,
Iran, Saudi Arabia, Lebanon, Kuwait, Syria, Oman, Yemen, and the United Arab Emirates),
the Indian peninsula (including most of India as well as portions of Nepal and Pakistan),
and parts of the western Asian nations of Turkmenistan, Uzbekistan, Kazakhstan, and
Afghanistan. It is not historically found in the incredibly dry areas of the Sahara
Desert nor is it found along the coast of the Mediterranean.

Habitat
Honey badgers are terrestrial animals that inhabit a wide variety of habitats, including
tropical and subtropical green forests, thorn forests, open woodlands, riparian forests
or grasslands, arid steppes, rocky hills, and deserts. Honey badgers occupy elevations
ranging from sea level to 4,050 meters. They typically do not live in the driest portions
of the Sahara Desert or in the chaparral biomes around the Mediterranean. They require
habitats with burrows, rock crevices, or other places in which they can shelter.

Physical Description
Honey badgers are large
mustelids
, with a body length of 60 to 70 cm and a mass ranging from 8 to 12 kg. Their size
varies across their geographic range, with measurements taken on honey badgers in
Africa showing them to be slightly larger than individuals from Asian populations.
This species exhibits sexual dimorphism, with the males being larger than the females.
Data from individuals in the Kalahari showed adult males to be about one third larger
than adult females. Older adult males also have an obvious scarred area on their back
(they are referred to as "scarbacks") that is probably the result of multiple bite
wounds. This species is characterized by having a stocky body, about 25 cm high at
the shoulder, with a large skull, small eyes, and a muscular neck and shoulders. Though
the color varies slightly with subspecies (see Other Comments below), in general the
lower (ventral) half of the body is a dark black, with an upper mantle that is either
grey or bright white. The lighter coloring extends the entire length of the body,
stopping at the base of the tail. The forefeet are strong and wide, with large claws
that are useful for grasping prey and running. In contrast, the hind feet are small
with short claws. Honey badgers have very thick, loose skin which prevents a predator
from getting a firm grasp on them and enables thm to easily twist and bite the attacker.
Little data are available for juvenile honey badgers. However, a report of a captive-born
honey badger described it as being hairless and weighing 0.23 kg at 2 days of age.
By the age of 3 months, the juvenile had a fully developed coat with a color pattern
like that of an adult.

Reproduction
Reproduction in honey badgers is generally not well studied, except for a 42 month-long
study in the Kgalagadi Transfrontier National Park in southern Africa. In this area,
honey badgers mate throughout the year, though mating activity is slightly more common
during the hot dry season, from September to December. Much of the recent literature
on the species describes honey badgers as solitary animals, coming together only briefly
for mating. However, some older reports, such as the reference to a 1910 paper by
Drake-Brockman in Vanderhaar & Hwang, 2003, indicate that males and females often
live in pairs. The scent-marking behavior of honey badgers appears to play an important
role in finding a mate. There are typically more males available to mate than there
are receptive females, due to the long period of time the offspring are dependent
on their mother, 12 to 16 months. This means that adult male honey badgers are competing
with each other for access to females. Male honey badgers that are more dominant will
typically be heavier and have larger testes. However, this dominance does not guarantee
mating success. In fact, a study of the genetic markers possessed by eight males and
eight females with overlapping ranges, and the 10 offspring of those females showed
that the dominant male fathered only half of the cubs. Since mating occurs in a burrow,
very few observations of the process have been made.
- Mating System
- polygynous
- polygynandrous (promiscuous)
Female honey badgers are in estrous for a minimum of two weeks, when mating occurs.
Mating is asynchronous, occurring at any point in the year, but research in southern
Africa suggests most breeding occurs from September to December. The gestation period
ranges from 50 to 70 days. Litters are reported to consist of one to two offspring,
but observations made in southern Africa suggest that honey badgers there raise only
a single young at a time. The young are born in a burrow and remain there until they
are about 3 months old and are weaned. Consequently, little information is available
about the size of newborns; however, one captive-born cub was reported to weigh 0.23
kg at 2 days old. Female honey badgers care for their young until they are one to
two years old. Female honey badgers reach sexual maturity significantly faster than
males, taking only 12 to 16 months, where males take two to three years.
Some literature sources report that honey badger reproduction can involve delayed
implantation, as occurs with some other
mustelid
species. The reproductive biology of the species has not been well studied across
its geographic range, but data collected in the southern Kalahari does not suggest
that delayed implantation occurs in that population.
- Key Reproductive Features
- iteroparous
- year-round breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- viviparous
- delayed implantation
Only female honey badgers are involved in the care of offspring, which are born blind
and hairless. For the first 3 months, honey badger cubs remain in the den, with the
mother returning to nurse. The mother will periodically (average of every 3 days)
move her cub to a new den, carrying it with her mouth. When the cub is two to three
months old, the mother honey badger will begin to bring prey items back to the den.
Once the cub begins to accompany its mother to forage, at around 3 months of age,
the pair will move to a different burrow each night. The cub will remain with its
mother for 12 to 16 months, with the mother providing all of the food for the first
10 to 12 months.
Both male and female honey badger cubs become independent at an average age of 14
months. However, females have reached their adult size at this age, and presumably
are sexually mature, and they immediately disperse away from their mother's home range.
Males, on the other hand, continue to grow after reaching the age of independence,
suggesting that they have not yet reached sexual maturity. Male cubs may remain in
or near to their mother's home range for a few months after they become independent.

Lifespan/Longevity
Honey badgers in the wild tend to live between 7 and 8 years due to predation and
risk of injury. In contrast, honey badgers bred in captivity live significantly longer,
with a maximum lifespan of 26 years.
Behavior
Honey badgers are solitary and nomadic. They occupy a large range, moving around daily
to forage. Female honey badgers tend to travel shorter distances per day, around 10
km, while males may forage for as much as 27 km per day. Males have been known to
meet up with other adult-sized honey badgers after foraging and exchange grunts while
sniffing each other and rolling around in the sand. Honey badgers have been known
to defecate in holes and mark with their urine or anal scent glands to indicate to
other animals that their burrow is nearby. Honey badgers are notoriously aggressive
animals. Males in particular defend mates with incredible ferocity if threatened.
Male interactions become aggressive if one of the males attempts to intrude into the
marked burrows, they begin a dominance dance to determine who will stay.

Home Range
In the southern Kalahari region, adult male honey badgers have an average home range
of 541 sq km, while adult females have a smaller average home range of 126 sq km.
Young males (independent but not yet sexually mature) have home ranges averaging 151
sq km. These home ranges are not exclusive, but instead overlap extensively. Adult
males may have overlapping home ranges, as do adult females. The home range of a dominant
adult male may overlap the ranges of as many as 13 females. Young males may have home
ranges that overlap entirely with the home range of an adult male. Despite the overlapping
home ranges of young males, adult males, and adult females, they don't exhibit territoriality.
Communication and Perception
Honey badgers communicate mainly through vocalizations. Adults emit loud grating noises,
comparable to a high-pitched bark. Young squeal and whine when in distress to gather
the attention of a parent. When faced with competing males, a male honey badger will
begin a ritualized dance consisting of various whole-body rotations. The dominant
male will be the one moving the most while the subordinate is mostly immobile. Honey
badgers mark their territory with urine or scent glands located in the anus.
- Other Communication Modes
- scent marks
Food Habits
Honey badgers are opportunistic foragers; the composition of the diet varies with
seasonal changes in prey abundance. They have a primarily carnivorous diet, frequently
dining on eggs, small rodents, snakes, birds, and frogs. While the majority of the
diet is carnivorous, honey badgers also eat fruit, roots, and bulbs. Bee hives are
preyed upon because the honey badger also likes to devour the bee larvae and honey
inside. They have been known to turn to carrion as a food source if other nourishment
is scarce.
An extensive study of honey badgers in the southern Kalahari found that, despite the
size difference between male and female honey badgers, their foraging patterns and
foraging success were remarkably comparable. They were observed capturing prey ranging
in size from 2 to 2000 g. The types of prey eaten by the honey badgers varied seasonally,
with small mammals making up most of the diet (80%) during the season of highest small
mammal abundance (September to December). Large snakes made up a significant portion
of the diet (58%) during the hot-wet season (January to April). Overall, adult male
honey badgers consumed an average of 1.3 kg of food per day while females consumed
an average of 0.9 kg per day.

Predation
Being a carnivorous species, honey badgers don't have an extensive list of predators.
Lions
and
leopards
tend to kill only older and weaker honey badgers, as the thick, loose skin makes
younger badgers difficult to grasp. The distinctive coloring of honey badgers, a black
body with a white mantle, mimics that of a baby cheetah, making any predators less
likely to attack. The enlarged anal glands can also produce a foul-smelling liquid
when they are threatened. This is typically accompanied by a threat display where
the honey badger's hair stands on end, the tail is held erect, a loud "rattling" sound
is made. Honey badgers also frequently charge attackers.
- Anti-predator Adaptations
- mimic
- aposematic
Ecosystem Roles
As opportunistic predators, honey badgers prey on a wide variety of other organisms
in the ecosystem. Although a supposed symbiotic relationship with greater honeyguides
(
Indicator indicator
) is often described in the literature and popular media (in which the bird guides
the honey badger to a beehive and is rewarded by getting to eat the leftovers after
the honey badger has eaten its fill), there is no empirical evidence to support the
existence of this relationship - it has not been observed to occur in the wild. Older
honey badgers that are less capable of defending themselves become prey for large
predators such as
lions
,
spotted hyaenas
, and
leopards
.
Economic Importance for Humans: Positive
Honey badgers are very efficient at controlling rodent and insect populations, effectively
reducing some pest-borne diseases. Apiculturists find them particularly useful, as
they act as honey guides to scout out potential locations for bee hives. Their organs,
skin, and other parts were seen as a symbol of ferociousness and tenacity, so humans
incorporated them into traditional medicine.
- Positive Impacts
- body parts are source of valuable material
- source of medicine or drug
- controls pest population
Economic Importance for Humans: Negative
Honey badgers can be quite fierce if startled by a human, thus making them a danger.
They have been known to carry rabies, which poses a health problem for the surrounding
humans and wildlife. They account for 26% of the damage done to commercial bee hives
by breaking into the hives and eating the larvae, which results in a monetary loss
for the beekeepers. Honey badgers have also been known to stray onto farmland and
attack livestock.
- Negative Impacts
-
injures humans
- bites or stings
- causes or carries domestic animal disease
Conservation Status
Honey badgers are not common anywhere in their range, although densities vary from
one region to another. The overall population shows a decreasing trend, despite the
fact that the species is protected in some of the countries that it inhabits. The
IUCN Red List identifies the species as "Least Concern" because, although the population
is declining, the species has a broad geographic range and is not a dietary specialist.
The Botswanan population is included on CITES Appendix III. The largest threat to
honey badgers is probably human activity. Individuals are often killed, either intentionally
or unintentionally with traps and poison baits by farmers and apiculturists trying
to reduce predator population, and others are subject to hunting for traditional medicinal
remedies. Honey badgers have large home ranges, so tracking and ensuring conservation
for them is exceedingly difficult.
Other Comments
The thick skin of honey badgers is said to be impervious to bee stings and snake fangs.
While their skin may offer them some protection from bees, they are certainly not
immune to the effects of bee stings as honey badgers have occasionally been caught
in apiary traps and have subsequently died as a result of numerous bee stings. Honey
badgers are known to eat a variety of venomous snakes, which suggests that they have
some adaptations for this diet. Some carnivorous mammals are known to exhibit a resistance
to the effects of snake venom, including species of opossum (
Didelphidae
), hedgehogs (
Erinacediae
), mongoose (
Herpestidae
), skunks (Mephitidae>>), and several mustelids (
Mustelidae
). It is likely that the honey badger also has resistance to snake venom, although
the exact physiological mechanism has not been demonstrated in honey badgers. For
other venom resistant mammals, the typical mechanisms are either factors in the blood
that inactivate the venom toxins, or that the resistant mammal has evolved slight
changes in the molecules that the snake venom targets, making those molecules less
susceptible to the damaging effects of the venom.
There are currently 12 recognized subspecies of
Mellivora capensis
, differing in location and the coat coloration: the Cape ratel (
M.c. capensis
), Ethiopian ratel (
M.c. abyssinica
), Turkmenian ratel (
M.c. buechneri
), Lake Chad ratel (
M.c. concisa
), black ratel (

M.c. maxwelli
), Arabian ratel (
M.c. pumilio
