The steenbok /ˈsteɪnbɒk, ˈstiːn-/[a] (Raphicerus campestris) is a common small antelope of southern and eastern Africa. It is sometimes known as the steinbuck or steinbok.

Description

[edit]
Steenbok phylogenetic relationships (simplified)[4]

Steenbok resemble small oribi, standing 45–60 cm (16"–24") at the shoulder, and weigh 7–16 kg (15–35 lb). Their coat is any shade from fawn to rufous, typically rather orange. The underside, including chin and throat, is white, as is the ring around the eye. Ears are large with "finger-marks" on the inside. Males have straight, smooth, parallel horns 7–19 cm (2.8–7.5 in) long (see image left). There is a black crescent-shape between the ears, a long black bridge to the glossy black nose, and a black circular scent-gland in front of the eye. The tail is not usually visible, being only 4–6 cm (1.6–2.4 in) long.

Distribution

[edit]

There are two distinct clusters in steenbok distribution. In East Africa, it occurs in central and southern Kenya and northern Tanzania. It was formerly widespread in Uganda,[2] but is now almost certainly extinct there. In Southern Africa, it occurs in Angola, Namibia, South Africa, Eswatini, Botswana, Mozambique, Zambia, Zimbabwe and probably Lesotho.

Habitat

[edit]

Steenbok live in a variety of habitats from semi-desert, such as the edge of the Kalahari Desert and Etosha National Park, to open woodland and thickets, including open plains, stony savannah, and Acacia–grassland mosaics. They are said to favour unstable or transitional habitats.[5] At least in the central part of Kruger National Park, South Africa, Steenbok show a distinct preference for Acacia tortilis savannah throughout the year, with no tendency to migrate to moister areas during the dry season (unlike many larger African savannah ungulates, including species sympatric with Steenbok in the wet season).[6]

Population density is typically 0.3–1.0 individuals per square kilometre, reaching 4 per km2 in optimal habitats.[7]

Diet

[edit]

Steenbok typically browse on low-level vegetation (they cannot reach above 0.9 m[8]), but are also adept at scraping up roots and tubers. In central Kruger National Park, Steenbok show a distinct preference for forbs, and then woody plants (especially Flueggea virosa) when few forbs are available.[6] They will also take fruits and only very rarely graze on grass.[6] They are almost entirely independent of drinking water, gaining the moisture they need from their food.

Behaviour

[edit]

Steenbok are active during the day and the night; however, during hotter periods, they rest under shade during the heat of the day. The time spent feeding at night increases in the dry season.[9] While resting, they may be busy grooming, ruminating or taking brief spells of sleep.[10]

Anti-predator

[edit]
Steenbok typically lie low in vegetation cover at the first sign of threat.

At the first sign of trouble, steenbok typically lie low in the vegetation. If a predator or perceived threat comes closer, a steenbok will leap away and follow a zigzag route to try to shake off the pursuer. Escaping steenbok frequently stop to look back, and flight is alternated with prostration during extended pursuit. They are known to take refuge in the burrows of aardvarks. Known predators include Southern African wildcat, caracal, jackals, leopard, martial eagle and pythons.

Breeding

[edit]

Steenbok are typically solitary, except for when a pair come together to mate. However, it has been suggested[5] that pairs occupy consistent territories while living independently, staying in contact through scent markings, so that they know where their mate is most of the time. Scent marking is primarily through dung middens. Territories range from 4 hectares to 1 square kilometre. The male is aggressive during the female's oestrus, engaging in "bluff-and-bluster" type displays with rival males—prolonged contests invariably involve well-matched individuals, usually in their prime.[10]

Breeding occurs throughout the year, although more fawns are born November to December in the southern spring–summer; some females may breed twice a year. Gestation period is about 170 days, and usually a single precocial fawn is produced. The fawn is kept hidden in vegetation for 2 weeks, but suckles for 3 months. Females become sexually mature at 6–8 months and males at 9 months.

Steenbok are known to live for 7 years or more.

Taxonomy

[edit]

Two subspecies are recognized: R. c. campestris in Southern Africa and R. c. neumanni of East Africa; although MSW3 also recognizes capricornis and kelleni.[11] Up to 24 subspecies have been described from Southern Africa, distinguished on such features as coat colour.

View on Grokipedia
from Grokipedia
The steenbok (Raphicerus campestris), also known as the steinbuck, is a small, shy endemic to the savannas and grasslands of southern and eastern . Measuring 70–95 cm in head-body length with a height of 45–60 cm and weighing 6–16 kg, it features a reddish-fawn coat, white underparts and throat, large white-lined ears, and— in males only—short, straight horns measuring 9–19 cm that grow parallel to the skull. This belongs to the Raphicerus, which includes three dwarf s, and is distinguished by its preorbital glands used for scent-marking and sharp hooves adapted for quick escapes. Widely distributed from and in the west to and in the east, the steenbok prefers flat, open habitats with scattered bushes or tall grass for cover, avoiding dense forests or rocky terrain. It obtains most of its moisture from vegetation, requiring minimal free water, and thrives in areas altered by human activity such as farmlands or roadsides as long as cover remains available. A selective browser and grazer, its diet consists primarily of short grasses, forbs, leaves, fruits, roots, and tubers, with a preference for fresh shoots of bushes and trees like species during the . Behaviorally, steenbucks are typically solitary or form monogamous pairs, maintaining territories of 4–5 hectares marked by dung middens and glandular secretions; they are most active and , resting in shade during the heat of the day. When threatened by predators such as , caracals, or eagles, they rely on by freezing in place, followed by explosive sprints or hiding in burrows like those of aardvarks. Breeding occurs year-round, with peaks in the rainy season; gestation lasts 168–210 days, resulting in a single calf (rarely twins) weighing about 1 kg at birth, which is weaned at three months and reaches at 9–12 months. In the wild, they live 7–9 years, though captives can exceed 8 years. The steenbok faces no major -level threats and is classified as Least Concern on the , owing to its adaptability and presence in numerous protected areas across its range. Local declines may occur due to , by , or predation by domestic dogs, but overall numbers remain stable, with a global estimated at over 600,000 individuals (East 1999, considered an underestimate). This resilient species plays a key ecological role as prey for larger carnivores and contributes to through its foraging habits.

Taxonomy

Classification

The steenbok bears the binomial name Raphicerus campestris, first described by in 1811. The common name "steenbok" originates from , translating to "stone buck." Within the taxonomic hierarchy, the steenbok is classified in the family , subfamily , tribe Raphicerini, and genus Raphicerus. Some classifications place the genus in subfamily Neotraginae, but it is commonly included in under tribe Raphicerini. The genus Raphicerus is shared with two other dwarf antelope species: the (R. melanotis) and Sharpe's grysbok (R. sharpei). Phylogenetically, the steenbok belongs to a of dwarf antelopes that diverged from larger bovid lineages approximately 15 million years ago during the middle , as inferred from fossil records and molecular analyses of evolution. This divergence highlights the of small-bodied antelopes in arid and ecosystems. Historical nomenclature includes synonyms such as "steinbuck" and older designations like Antilope campestris or variants attributed to Martin Hinrich Lichtenstein, such as Antilope tragulus var. pallida.

Subspecies

The steenbok (Raphicerus campestris) comprises two primary subspecies: R. c. campestris, distributed across including , , , , and adjacent regions, and R. c. neumanni, found in eastern from southern to central . These subspecies reflect regional adaptations within the species' habitats, with over 24 historical names proposed but only these two widely accepted based on consistent morphological and geographic distinctions. The subspecies are geographically isolated by the extensive woodlands of the , which form an impenetrable barrier to dispersal and result in no observed interbreeding between southern and eastern populations. This separation aligns with broader patterns in African antelope distributions, where central African forests limit between disjunct groups. Morphological differences between R. c. campestris and R. c. neumanni are subtle but include variations in coloration and ; the southern form typically exhibits a paler fawn to grayish pelage, while the eastern form shows richer reddish-brown tones, with the latter being slightly larger overall and possessing marginally longer horns in males. These traits, though minor, underscore the ' adaptation to local environmental conditions. Historically, the species was first scientifically described as Raphicerus campestris by in 1811, based on specimens from the . The eastern subspecies R. c. neumanni was described by Paul Matschie in 1894.

Description

Physical characteristics

The steenbok (Raphicerus campestris) is a petite characterized by a head-body length of 70–95 cm, shoulder of 45–60 cm, and tail length of 4–6 cm. Adults typically weigh 7–16 kg, exhibiting a slender build that emphasizes agility. Its long, thin legs are adapted for rapid movement across open landscapes, complemented by a high-held head posture that enhances vigilance. The features short, coarse in shades ranging from fawn to rufous-brown on the upper body, creating a uniform coloration with a sharp demarcation to the white underparts, including the belly, throat, and a distinctive rump patch. The legs and underside of the short tail are also white, while facial markings consist of a slender black wedge extending from the nose toward the forehead. A conspicuous is positioned just anterior to the eyes, used for scent marking. Males bear straight, parallel horns measuring 7–19 cm in length, ringed at the base and oriented vertically; females lack horns. The steenbok possesses large eyes encircled by fine white hairs and prominent ears lined with white internally, contributing to its alert appearance. The hooves are sharp and robust, enabling effective navigation over sandy and rocky substrates.

Sexual dimorphism

Sexual dimorphism in steenbok (Raphicerus campestris) is moderate, manifesting primarily in horn presence, minor body size variations, and development rather than pronounced differences in overall morphology or coloration. Males bear straight, parallel, smooth horns that measure 7–19 cm in length and project vertically from the head, serving key roles in territorial defense and displays against rivals. Females completely lack horns, resulting in a sleeker facial profile. These horns, along with associated behaviors, facilitate mate attraction and , though subtle size disparities between sexes may also influence selection dynamics. In terms of body size, females tend to be slightly larger than males, averaging a shoulder height of about 51 cm and body weight of 11 kg, compared to 48 cm and 9.5 kg for males; overall, adults range from 45–60 cm at the shoulder and 7–16 kg regardless of sex. Both sexes share similar body proportions, including a compact build with large ears and a short , and exhibit uniform reddish-fawn pelage with white underparts, lacking any sex-specific color variations. Preorbital glands, located in front of the eyes, show with more pronounced development in males, enabling intensified scent marking of territories through rubbing on . This glandular difference supports male-specific territorial maintenance, while females allocate greater effort to concealing and protecting fawns post-birth, reflecting complementary roles in pair-bonded .

Distribution and

Geographic range

The steenbok (Raphicerus campestris) is distributed across southern and eastern , with its range extending from the and provinces of South Africa northward through , , , southern , western , and , as well as eastward into central and southern and northern and central , with records from and historical presence in where it is now considered regionally extinct. The distribution comprises two disjunct populations separated by over 1,000 km of unsuitable : a southern population south of the River and an eastern population north of the river in central and southern and northern and central . hosts the most abundant populations, particularly in the Free State and drier northwestern regions, while , , and also support significant numbers; the species is likely extirpated from the lowlands of . Historically, the steenbok expanded its range following the Pleistocene, with evidence indicating past presence in regions that are now arid and unsuitable, such as parts of the Kalahari and deserts. The current extent covers approximately 3.5 million km², reflecting adaptation to landscapes post-glacial period.

Preferred habitats

The steenbok (Raphicerus campestris) primarily inhabits open grasslands, savannas, and lightly wooded areas where the grass layer remains short, typically under 50 cm in height, facilitating clear visibility for predator detection and efficient on accessible . These habitats often feature gently undulating plains with scattered shrubs and trees, providing a balance between open space and intermittent cover, and the favors disturbed or overgrazed patches rich in pioneer forbs and palatable grasses. While adaptable, steenbok tolerate semi-arid environments, such as the edges of the and , extending to mesic woodlands and shrublands, but they avoid dense forests, wetlands, thickets, rocky slopes, and steep mountains that limit mobility or visibility. In selected microhabitats, individuals position themselves near bushes or thorn thickets for shelter from predators and extreme weather, often at elevations from to 3,500 m, where such structural elements enhance survival in otherwise exposed landscapes. Key adaptations enable steenbok to thrive in these varied but predominantly dry habitats, including water independence achieved through moisture derived from succulent , leaves, and geophytes, supported by low metabolic rates and efficient thermal regulation that minimize loss. This physiological resilience allows persistence in regions with annual rainfall as low as 200 mm up to 1,000 mm, encompassing semi-arid to subtropical conditions without reliance on free-standing sources.

Ecology

Diet and foraging

The steenbok (Raphicerus campestris) is primarily a browser, with its diet consisting predominantly of dicotyledonous plants such as leaves, shoots, flowers, and fruits from forbs, shrubs, and succulents. Studies in Kruger National Park indicate that the annual diet comprises approximately 57% forbs, 41% browse from woody plants, and 1% creepers, confirming its status as a pure browser with minimal grass consumption (around 8-10% in some analyses, often increasing slightly during dry seasons when fresh browse is scarce). Selective feeding targets nutrient-rich, tender growth, including species like Portulacaria afra in arid regions, while avoiding toxic plants through taste discrimination to meet high protein and carbohydrate needs associated with its small size and activity levels. Daily vegetation intake averages 0.5-1 kg of fresh material for adults, reflecting efficient in its specialized that allows extraction of nutrients from low-quality . Foraging occurs solitarily and is largely crepuscular, with about 33% of diurnal time dedicated to feeding and up to 57% nocturnal activity during dry periods to access dew-laden ; individuals typically cover 1-3 km per day within small home ranges of around 0.62 km². Preorbital glands are used to scent-mark preferred feeding areas as part of territorial maintenance, reinforcing access to high-quality resources. Water requirements are met almost entirely through metabolic water derived from oxidized and the moisture content of (typically 50-70% in browse), enabling survival in arid habitats without frequent drinking; individuals rarely approach sources and exhibit physiological adaptations like low metabolic rates to minimize loss.

Predators and anti-predator adaptations

The primary predators of the steenbok (Raphicerus campestris) include mammalian carnivores such as leopards (Panthera pardus), (Acinonyx jubatus), caracals (Caracal caracal), (Canis mesomelas and Lupulella adusta), and servals (Leptailurus serval), as well as reptiles like African rock pythons (Python sebae) and large raptors including martial eagles (Polemaetus bellicosus). Feral dogs also pose a threat, particularly near human settlements. Human hunting is rare but can occur opportunistically. Steenbok employ a suite of anti-predator adaptations to evade detection and capture, beginning with immediate freezing upon sensing danger, often remaining motionless in cover for up to 90 seconds to avoid alerting predators. This behavior is facilitated by their choice of habitats with tall grass and scattered shrubs, providing escape routes and concealment, while their large eyes and ears enhance vigilance for early threat detection. If pursued, steenbok rely on explosive bursts of speed, executing huge bounds in a stotting-like gait with the head held high to signal fitness and potentially deter predators from continuing the chase. During flight, they frequently pause to glance backward, assessing the threat despite the increased risk this poses. Predation exerts significant pressure on steenbok populations, with weaning juveniles experiencing mortality rates of approximately 50%, primarily from the diverse predator , while adult mortality is lower at around 15%. This differential impact contributes to overall rates of 21-32% in favorable conditions, helping to maintain low densities of 1-5 individuals per km² in optimal habitats where cover and resources balance predation risk.

Behavior and social structure

Daily activity patterns

Steenbok (Raphicerus campestris) display a predominantly diurnal activity , with and movement peaking in the early morning and late afternoon when temperatures are lower and higher. Diurnal activity typically involves about 33% of the day spent , with the remainder dedicated to ruminating and resting. During midday heat, individuals seek shade under bushes or for concealment and , lying down in these sites where resting time correlates strongly with rising temperatures (r = 0.84, p < 0.01). Activity is heavily influenced by environmental factors, particularly , which prompts reduced mobility and increased idling in shade as heat intensifies; steenbok adjust by shifting toward crepuscular patterns in hot conditions to minimize . Predation risk also shapes rhythms, with heightened vigilance at night and a tendency for greater daytime activity in lion-occupied areas to avoid nocturnal threats, enduring higher heat loads (up to 3°C above typical) as a . Seasonal variations occur, with more nocturnal during the —comprising 57% of nighttime hours—compared to the , likely due to cooler nights and resource availability. Resting occurs in concealed spots under low vegetation, providing cover while allowing quick detection of threats; activity remains largely solitary or paired, with minimal grouping beyond mates. Daily movements average 4.5 km over 24 hours within compact home ranges that vary by habitat, averaging approximately 0.62 km² (62 ha) in some savanna areas such as , though overall estimates range from 4–100 ha across studies.

Territoriality and social bonds

Steenbok (Raphicerus campestris) exhibit a largely solitary , typically occurring alone or in stable monogamous pairs that share territories but often forage and rest separately. Adult individuals maintain separate, fixed territories that do not overlap significantly, promoting independence and minimizing intraspecific conflict. These territories, ranging from 5 to 15 hectares for adults in some habitats (with broader estimates of 4–100 ha across studies), are defended primarily by resident males against intruders of the same sex, though females also show territorial behaviors toward other females. Scent marking via pre-orbital, , and intermandibular glands, along with the use of communal latrines, delineates boundaries and facilitates communication without frequent aggressive encounters. Territorial defense involves displays such as horn threats, chasing, or among males, but overt is rare due to mutual recognition among neighbors, who often tolerate passage through adjacent areas. Home ranges, which are larger at 12 to 30 hectares and may overlap slightly between sexes (varying up to 62 ha or more in certain environments), allow for flexibility while upholding core territorial exclusivity. This system supports population densities of up to one steenbok per 30 hectares in optimal habitats, reflecting an to resource-scarce environments where solitary living reduces . Latrines, positioned at territory perimeters or core areas, serve not only for demarcation but also to maintain familiarity and subtle social bonds among dispersed individuals, as observed in related small ungulates. Social bonds in monogamous pairs are stable and long-term, though direct interactions are limited, with pairs forming briefly for up to three days and mother-offspring associations lasting until the young reaches independence at around seven months. This loose structure contrasts with more gregarious antelopes, emphasizing stealth and low visibility to evade predators in open habitats. Neighboring steenbok may exhibit submissive behaviors during intrusions, further stabilizing social interactions and preventing escalation.

Reproduction

Mating system

Steenbok (Raphicerus campestris) exhibit a where pairs share territories but live largely solitarily, coming together only for breeding; these long-term territorial associations persist throughout the animals' lives unless one partner dies. These pairs typically form around , with females maturing at 6-8 months and males at approximately 9 months, after which they establish and defend shared territories typically ranging from 4–25 hectares, up to 100 hectares in some areas. Males actively guard their mates year-round, exhibiting heightened aggression toward intruders during the female's estrus and using scent marking to delineate boundaries and signal pair status. Courtship behaviors reinforce these associations and occur opportunistically when the female enters estrus. Males pursue the receptive female, engaging in chasing, mutual grooming, and intensified scent marking via preorbital glands, interdigital glands, and dung middens to advertise availability and maintain contact within the territory. Females signal receptivity through behavioral cues and olfactory signals, including urine and glandular secretions, prompting the male's displays. Breeding in steenbok is largely aseasonal and opportunistic, occurring year-round across their range, though birth peaks align with the onset of the rainy season—typically November to December in southern Africa or summer months elsewhere—to coincide with increased forage availability driven by rainfall. This timing enhances offspring survival by leveraging post-rain vegetation growth, with some females capable of breeding twice annually under favorable conditions.

Breeding and offspring development

The gestation period for steenbok females lasts 168–210 days, resulting in the birth of typically a single precocial lamb, though twins occur rarely (less than 5% of cases). Births take place year-round across their range, with peaks coinciding with the rainy seasons from November to December in southern Africa. Newborn lambs weigh approximately 0.9–1 kg and can stand, walk, and nurse within minutes of birth, exhibiting immediate mobility typical of precocial ungulates. To minimize predation risk, the employs a hiding , concealing the lamb in dense or burrows and visiting periodically to nurse, often moving it to a new location every few days during this phase. The lamb remains hidden for 2–4 weeks initially, after which it begins following the during activities while still dependent on her . The father contributes indirectly to protection by maintaining and defending the pair's against intruders. typically occurs around 3 months of age, marking the transition to a primarily herbivorous diet. Juveniles achieve independence between 6 and 8 months, around the time they establish their own territories, though full dispersal may extend to 13–18 months in some cases. is attained at 6–12 months, with females reaching it earlier (6–7 months) than males (9 months). In the wild, steenbok typically live 3–4 years, though some may reach 7 years or more; in captivity, they can exceed 10 years.

Conservation

Population status

The steenbok (Raphicerus campestris) is classified as Least Concern on the , a status assigned in the assessment by the IUCN SSC Antelope Specialist Group and maintained since then due to its wide distribution and relatively large population size. The global population is estimated at 600,000 to 663,000 individuals, with approximately 25% occurring in protected areas across its range in southern and eastern . These estimates, derived from aerial and ground surveys, indicate a robust overall abundance, though precise counts of mature individuals remain challenging due to the species' secretive nature and habitat preferences. Population densities vary significantly by habitat, typically ranging from 0.3 to 1.0 individuals per km², with higher densities up to 4 individuals per km² recorded in optimal habitats such as those in . In these protected areas, steenbok numbers have remained stable over recent decades, supported by consistent monitoring efforts. Lower densities, around 0.3–1.0 per km², prevail in less productive or arid regions, reflecting the species' adaptability to diverse environments without extreme fluctuations in core habitats. Overall population trends are stable, with no evidence of major range contraction since , though localized declines have been noted in fragmented landscapes outside protected zones. The two primary regional populations—one in and the other in eastern Africa—are roughly equal in size, each comprising a substantial portion of the total. Monitoring relies on methods such as camera traps for detecting individuals in dense cover and line transects for via sampling, enabling effective tracking of abundance and distribution.

Threats and conservation measures

The primary threats to steenbok populations stem from anthropogenic activities, including habitat loss and fragmentation due to expanding , farming, and settlements, which have altered up to significant portions of their range in . by domestic exacerbates this by reducing available forage and increasing competition with species like , particularly in arid and semi-arid regions where steenbok densities are already low. Additionally, illegal hunting and snaring target juveniles and adults, leading to localized declines, while legal contributes to harvest pressure in some areas. Depredation by domestic and dogs poses a further , especially near settlements. Climate-related impacts, such as prolonged droughts, diminish quality and quantity, heightening steenbok vulnerability to and predation in altered habitats, compounded by encroachment that modifies vegetation structure. These factors have resulted in population declines in fragmented landscapes, though overall trends remain stable. Conservation efforts focus on habitat protection and , with approximately 25% of the estimated 663,000 steenbok occurring in protected areas across more than 50 reserves, including in , in , in and , and the Greater Limpopo Transfrontier Park spanning , , and . Steenbok are classified as Least Concern on the , reflecting their wide distribution and stable populations, with no subspecies currently endangered. Community-based programs in , such as those supported by the Namibian Association of CBNRM Support Organisations (NACSO), have successfully reduced through local patrols and benefit-sharing from tourism and regulated hunting, leading to population recoveries in fenced conservancies and private lands. These initiatives promote permeable fencing to maintain and monitor densities to inform strategies.
