Young bohor reedbucks that are found by Bahima herdsmen are sometimes raised by goats. Sometimes captured bohor reedbucks are herded right along with the sheep and goats. In captivity, bohor reedbucks have been known to live as long as ten years (Kingdon, 1989).
Perception Channels: tactile ; chemical
Bohor reedbucks have been found grazing on farmers' crops, especially wheat and other grains (Kingdon, 1989).
Bohor reedbucks have been a game animal in Africa in the past. During the dry season, bohors are hunted with dogs and nets in Uganda. Bohors with the largest horns are prized by hunters (Kingdon, 1989)
The bohor reedbuck is a grazing animal and prefers grasses with high protein and low fiber. During the dry season they eat other types of vegetation if their normal diet is not available. The bohor reedbuck is a water dependent animal but may not need water if they are in green pastures (Estes, 1991). In farming communities, bohor reedbucks have been spotted grazing on wheat and other grains (Kingdon, 1989).
The bohor reedbuck is found in the floodplain and drainage-line grasslands of the northern and southern Savanna on the continent of Africa (Estes, 1991).

The bohor reedbuck is a medium sized antelope. Males range in height between 75 - 89 cm whereas females range in height from 69 - 76 cm. The males are not only larger than the females but their markings are more defined as well. The color of reedbucks ranges from yellow to a grayish brown, but in general, bohor reedbucks are yellower than the other reedbuck species. Bohor reedbucks have a round bare spot beneath each ear along with white underparts and white markings under their tails. Young bohors have darker and longer hair than the adults. Just male bohor reedbucks have horns, which vary in size from 20 -41 cm and slightly hook forward (Estes, 1991).
Range mass: 36 to 55 kg.
Other Physical Features: endothermic ; bilateral symmetry
The habitats of the bohor reedbuck are grasslands and wide wideplains that have tall grass in which they can hide. They are rarely found on steep slopes or tall grassland because of the poor vegetation.
Terrestrial Biomes: savanna or grassland ; forest ; scrub forest
Although there is not a set breeding season for the bohor reedbuck, there is a breeding peak around the rainy season. The gestation period is seven and a half months and usually only one calf is born per breeding season. Young calves are hiders, and they remain in seclusions for up to eight weeks. After this period, the young calves begin to form age groups with those of similar age. A close bond between the young and the mother lasts for about eight to nine months. Males are mature at three years of age while the females mature at two years, and in some cases in even just a year, and can conceive every nine to fourteen months (Estes, 1991).

Bahnivec severní (Redunca redunca), známý též pod názvem senegambský, je středně velký turovitý sudokopytník obývající otevřené planiny nebo vrchoviny s řídkým porostem poblíž vody v severní Africe.
Vzhledem se výrazně podobá bahnivci jižnímu (Redunca arundinum). Srst na trupu je nažloutlá nebo červeně hnědožlutá; břišní část těla, hrdlo, oblast kolem očí a větší část 15-45 cm dlouhého ocasu je bílá. Pod ušními boltci se nachází nápadná šedivá skvrna vyznačující umístění pachové žlázy. Tělo je dlouhé 1,1-1,6 m a hmotnost se pohybuje mezi 35 a 65 kg. Prstencové rohy, které mají pouze samci, jsou zahnuté směrem dopředu.
Bahnivec severní žije buď samotářsky nebo v malých stádech, tvořených max. dvaceti jedinci, která se v období sucha pro větší bezpečí shlukují. Horké dny tráví ve stínu stromů nebo keřů, přes dny s nižší teplotou je aktivní i za bílého dne, kdy hledá trávu, listy a mladé výhonky rákosu, v jehož blízkosti se skrývá a žije. Jde o plaché zvíře, které při trhavém běhu potřásá huňatým ocasem. Mezi jeho hlavní predátory patří lvi, leopardi a psi hyenovití. Samci vlastní teritoria, která si značí pomocí výměšku z pachových žláz, močí nebo trusem. Při obraně svého teritoria provádí toporné výskoky se zdviženou hlavou.
Při svatebních tancích několikrát vyskakují samci před samicemi do výšky, přičemž vydávají výrazné, pískavé zvuky; samice se ozývají zvuky podobným žabímu skřehotání. Po 7,5 měsíční březosti rodí samice jediné mládě, které je po narození zbarveno šedohnědě. Ve vysoké vegetaci bývá ukryto až po dobu osmi měsíců. Po skončení tohoto období začnou tvořit mláďata menší skupinky, v kterých žijí několik následujících týdnů. Samci dosahují pohlavní dospělosti ve věku tří let, samice o rok dříve.

Der Riedbock (Redunca redunca), zur Unterscheidung von anderen Arten der Gattung Redunca auch als Gemeiner Riedbock oder Senegal-Riedbock bezeichnet, ist eine afrikanische Antilope.
Diese Antilope ist mit einer Schulterhöhe von 70 bis 90 Zentimetern etwas kleiner als der Große Riedbock. Die Tiere erreichen ein Gewicht von bis zu 50 Kilogramm, die Hörner des Männchens werden bis zu fünfzig Zentimeter lang.[1] Die Oberseite ist gelblich bis rotbraun, die Unterseite weiß; die Vorderläufe haben schwarze Zeichnungen. Nur Männchen tragen Hörner, die gedrungen und nach vorn gebogen sind. Unterhalb des Ohres haben sie eine auffällige Duftdrüse.
Der Riedbock ist über Schwemmebenen, Sümpfe und Auenwälder Westafrikas verbreitet. Lebensraum und Lebensweise sind dem des Großen Riedbocks ähnlich.
Männliche Riedböcke sind territoriale Einzelgänger, die alle sich in ihrem Gebiet aufhaltenden Weibchen beanspruchen. Die Weibchen leben in lockeren Verbänden, die sich schnell auflösen, wenn sie sich in Regionen mit guter Deckung aufhalten. Nur in offenem Gelände ohne Schutz bilden sie Herden von bis zu zehn Tieren. Zu der Verhaltensweise des Riedbocks gehört es, bei Annäherung eines Fressfeindes unbeweglich in der Deckung auszuharren und dann plötzlich aufzuspringen und zu fliehen. Während der Flucht geben sie einen lauten Pfiff von sich, der Schwanz wird aufrecht getragen, dabei wird der weiße Spiegel an den Hinterbeinen und die weiße Unterseite des Schwanzes sichtbar, was möglicherweise der Kommunikation mit Artgenossen dient.[2]

The bohor reedbuck (Redunca redunca) is an antelope native to central Africa. The animal is placed under the genus Redunca and in the family Bovidae. It was first described by German zoologist and botanist Peter Simon Pallas in 1767. The bohor reedbuck has five subspecies. The head-and-body length of this medium-sized antelope is typically between 100–135 cm (39–53 in). Males reach approximately 75–89 cm (30–35 in) at the shoulder, while females reach 69–76 cm (27–30 in). Males typically weigh 43–65 kg (95–143 lb) and females 35–45 kg (77–99 lb). This sturdily built antelope has a yellow to grayish brown coat. Only the males possess horns which measure about 25–35 cm (9.8–13.8 in) long.
A herbivore, the bohor reedbuck prefers grasses and tender reed shoots with high protein and low fiber content. This reedbuck is dependent on water, though green pastures can fulfill its water requirement. The social structure of the bohor reedbuck is highly flexible. Large aggregations are observed during the dry season, when hundreds of bohor reedbuck assemble near a river. Males become sexually mature at the age of three to four years, while females can conceive at just one year of age, reproducing every nine to fourteen months. Though there is no fixed breeding season, mating peaks in the rainy season. The gestation period is seven and a half months long, after which a single calf is born. The calves are weaned at eight to nine months of age.
The bohor reedbuck inhabits moist grasslands and swamplands as well as woodlands. The bohor reedbuck is native to Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ethiopia, the Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Mali, Mauritania, Niger, Nigeria, Rwanda, Senegal, Sudan, Tanzania and Togo. The animal is possibly extinct in Ivory Coast and Uganda. Reckless hunting and loss of habitat as a result of human settlement have led to significant decline in the numbers of the bohor reedbuck, although this antelope tends to survive longer in such over-exploited areas as compared to its relatives. The total populations of the bohor reedbuck are estimated to be above 100,000. Larger populations occur in eastern and central Africa than in western Africa. The International Union for Conservation of Nature (IUCN) rates the bohor reedbuck as of least concern.
The scientific name of the bohor reedbuck is Redunca redunca. The animal is placed under the genus Redunca and in the family Bovidae. It was first described by German zoologist and botanist Peter Simon Pallas in 1767.[2] The three species of Redunca, including the bohor reedbuck, are the least derived members of the tribe Reduncini (except the genus Pelea). The order of size in the genus Redunca is an evidence supporting the descent of the reduncines from a small ancestor.[3]
Five subspecies of the bohor reedbuck have been recognized:[3][4]
_male.jpg)
The bohor reedbuck is a medium-sized antelope. The head-and-body length is typically between 100–135 cm (39–53 in).[5] Males reach approximately 75–89 cm (30–35 in) at the shoulder, while females reach 69–76 cm (27–30 in).[6] Males typically weigh 43–65 kg (95–143 lb) and females 35–45 kg (77–99 lb). The bushy tail is 18–20 cm (7.1–7.9 in) long.[5][7] This reedbuck is sexually dimorphic, with males 10% to 20% larger than females and showing more prominent markings.[6][8] Of the subspecies, R. r. cottoni is the largest, whereas R. r. redunca is the smallest.[3]
This sturdily built antelope has a yellow to grayish-brown coat. Generally, the bohor reedbuck is yellower than other reedbucks. The large and diffuse sebaceous glands present on the coat make the coat greasy and give it a strong odor.[9] Juveniles are darker than the adults as well as long-haired.[6] While R. r. bohor appears yellowish gray, R. r. wardi is richly tinted.[3] The undersides are white in color. A few distinct markings can be observed—such as a dark stripe on the front of each foreleg; white markings under the tail; and a pale ring of hair around the eyes and along the lips, lower jaw, and upper throat.[5][6] However, R. r. redunca lacks dark stripes on its forelegs.[3] The males have thicker necks. Its large, oval-shaped ears distinguish it from other antelopes.[10] There is a round bare spot below each ear.[6] Apart from sebaceous glands, bohor reedbuck have a pair of inguinal glands and vestigial foot glands, and four nipples.[9] A bohor reedbuck can survive for at least ten years.[8] The tracks of the bohor reedbuck are slightly smaller than those of the southern reedbuck.[11]
As a prominent sign of sexual dimorphism, only males possess a pair of short, stout horns, that extend backward from the forehead and hook slightly forward.[8] The horns measure about 25–35 cm (9.8–13.8 in).[5] However, some Senegalese individuals have longer and wide-spreading horns.[8] In comparison to the other reedbucks, the bohor reedbuck has the shortest and most hooked horns.[12] The longest horns are observed in R. r. cottoni, which are hooked less than normal and may curve inwards. In contrast to R. r. cottoni, R. r. bohor has short and stout horns, with hooks pointing forward.[3] The length of the horns of an individual of a certain region seems to be related to the population density in that region to some extent. While short horns are observed in individuals of eastern Africa, where populations are dispersed, longer and wide-spreading horns are found on animals in the Nile valley, where populations are concentrated.[4]
The bohor reedbuck is host to several parasites. The most notable helminths found in the bohor reedbuck are Carmyerius papillatus (in the rumen), Stilesia globipunctata (in the small intestine), Trichuris globulosa (in the caecum), Setaria species (in the abdominal cavity), Dictyocaulus species (in the lungs) and Taenia cysts (in the muscles). Other parasites include Schistosoma bovis, Cooperia rotundispiculum, Haemonchus contortus, species of Oesophagostomum, Amphistoma and Stilesia. The common ticks found on the bohor reedbuck are Amblyomma species and Rhipicephalus evertsi.[3]
Bohor reedbuck are active throughout the day, seeking cover during the daytime and grazing in the night. A large proportion of the whole day is spent on feeding and vigilance.[13] They can easily camouflage in grasses and reeds, and hide themselves rather than running from danger.[8] When threatened, they usually remain motionless or retreat slowly into cover for defense, but if the threat is close, they flee, whistling shrilly to alert the others. It hides from predators rather than forming herds in defense. Many predators, including lions, cheetahs, leopards, hyenas, wild dogs and crocodiles prey on the reedbuck.[5]
If shade is available, females remain solitary; otherwise, they, along with their offspring, congregate to form herds of ten animals. Female home ranges span over 15–40 hectares (37–99 acres; 0.058–0.154 sq mi), while the larger territories of males cover 25–60 hectares (62–148 acres; 0.097–0.232 sq mi). These home ranges keep overlapping. As the daughters grow up, they distance themselves from their mothers' home ranges. Territorial males are much tolerant; they may even associate with up to 19 bachelor males in the absence of females. As many as five females may be found in a male's territory. Territorial bulls drive out their sons when they start developing horns (when they are about a year-and-a-half old). These young males form groups of two to three individuals on the borders of territories, till they themselves mature in their fourth year.[8] Large aggregations are observed during the dry season, when hundreds of bohor reedbuck assemble near a river.[6]
Two prominent forms of display among these animals is whistling and bounding. Instead of scent-marking its territory, the reedbuck will give a shrill whistle to make the boundaries of its territory be known. As it whistles, it expels air through its nose with such a force that the whole of its body vibrates. These whistles, usually one to three in number, are followed by a few stotting bounds. This behavior is also used to raise alarm in herds. In this, the reedbuck raises its neck, exposing the white patch on its throat, but keeping the tail down, and leaps in a way similar to the impala's jumps, landing on its forelegs. This is accompanied by the popping of the inguinal glands in the legs. Fights begin with both opponents holding their horns low, in a combat stance; followed by the locking of horns and pushing one another. These fights can even lead to deaths.[9]
A herbivore, the bohor reedbuck prefers grasses and tender reed shoots with high protein and low fiber content. This reedbuck is dependent on water, though green pastures can fulfill its water requirement.[6] A study of the bohor reedbuck's diet in Rwenzori Mountains National Park (Uganda) revealed that, throughout the year, the most preferred species was Sporobolus consimilis. Other grasses the animals fed on included Hyparrhenia filipendula, Heteropogon contortus and Themeda triandra, all of which are species commonly found in heavily grazed grasslands. Bohor reedbuck preferred Cynodon dactylon and Cenchrus ciliaris in the wet season, and switched to Sporobolus pyramidalis and Panicum repens in the dry season. Though they rarely feed on dicots, these can include Capparis and Sida species. On regularly burnt pastures, the bohor reedbuck feeds on Imperata species, while in places close by water sources, it eats Leersia and newly sprouted Vossia species (like topi and puku).[3]
Primarily a nocturnal grazer, the bohor reedbuck may also feed at daytime. A study showed that feeding peaked at dawn and late afternoon. In the night, two feeding peaks were observed once again: at dusk and midnight.[14] They traverse a long way from their daytime refuges while grazing. Seasonal differences in the amount of time spent while grazing in a particular area is possibly related to the availability and quality of grasses there.[3] The bohor reedbuck often grazes in association with other grazers such as hartebeest, topi, puku and kob. In Kenyan farmlands, the reedbuck may feed on growing wheat and cereals.[8]
Males become sexually mature at the age of three to four years, while females can conceive at just one year of age, reproducing every nine to fourteen months. Though there is no fixed breeding season, mating peaks in the rainy season.[9] Fights for dominance take place in some particular "assembly fields", where up to 40 males may assemble in an area of 1 hectare (2.5 acres; 0.0039 sq mi). Some parts of these grounds are the main attractions - marked with dung and urine. The reason behind the attractiveness of these few spots for sexually active males is the oestrogen in the females' urine.[4]
Courtship begins with the dominant male approaching the female, who then assumes a low-head posture and urinates. Unresponsive females run away on being pursued by a male. A male keen on sniffing the female's vulva keeps flicking his tongue. As they continue their "mating march", the male licks the female's rump and persistently attempts mounting her. On mounting, the males tries to clasp her flanks tightly. If she stands firmly, it is a sign that she is ready to mate. Copulation is marked by a single ejaculation, after which both animals stand motionless or a while, and then resume grazing.[6][9]
The gestation period is seven and a half months long, after which a single calf is born. The mothers keep their offspring concealed for as long as eight weeks. The mother keeps within a distance of 20–30 m (66–98 ft) of its calf. Nursing, usually two to four minutes long, involves licking the whole body of the calf and suckling. The infant is suckled usually once in the day and one to two times at night. The female's previous calf usually resists separation. At the age of two months, the calf begins grazing alongside its mother, and seeks protection from her if alarmed. Though after four months the calf is no more licked, it may still be groomed by its mother.[9] The calves are weaned at eight to nine months of age.[6]
The bohor reedbuck inhabits moist grasslands and swamplands as well as woodlands. It is found in two kinds of habitat in northern Cameroon: the seasonally flooded grasslands rich in grasses like Vetiveria nigritana and Echinochloa pyramidalis (in the Sahelo-Sudan region) and Isoberlina woodlands (in the Sudano-Guinean region).[3] Often found on grasslands susceptible to floods and droughts, the bohor reedbuck can adapt remarkably well to radical seasonal changes and calamities.[15] It is not so widespread as the bushbuck due to its habitat requirements.[16] In some margins of its range, the bohor reedbuck shares its habitat with the mountain reedbuck. The ranges of the bohor reedbuck and southern reedbuck extensively overlap in Tanzania.[3]
Endemic to Africa, the bohor reedbuck is native to Benin, Burkina Faso, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Ethiopia, the Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Mali, Mauritania, Niger, Nigeria, Rwanda, Senegal, Sudan, Tanzania and Togo. The animal is possibly extinct in Ivory Coast and Uganda.[1] Formerly widespread in western, central and eastern Africa, its present range extends from Senegal in the west to Ethiopia in the east.[17] Among the three reedbuck species, bohor reedbuck is the most widespread in Tanzania.[18] Its status in Burundi, Eritrea, Ghana and Togo is uncertain, while it is rare in Niger and Nigeria.[3]
Reckless hunting and loss of habitat as a result of human settlement have led to a significant decline in the numbers of the bohor reedbuck,[19] although this antelope tends to survive longer in such over-exploited areas as compared to its relatives.[17] Natural calamities, like drought, are also major threats. While populations have declined in northern Cameroon due to degradation of floodplains through the construction of upstream dams,[1] their habitat has been destroyed in Chad and Tanzania due to expansion of agriculture and settlement.[3] Several deaths occur due to roadkill and drowning as well.[3] During the dry season, bohor reedbuck are hunted with dogs and nets in Uganda. Reedbuck with the largest horns are prized by hunters.[6]
The total populations of the bohor reedbuck are estimated to be above 100,000. Though the populations are decreasing, it is not sufficiently low to meet the near threatened criterion. Thus, the IUCN rates the bohor reedbuck as of least concern. Around three-fourths of the populations survive in protected areas.[1] Populations of the reedbuck are either declining or uncertain in Boucle du Baoulé National Park (Mali); Comoé National Park (Ivory Coast); Mole and Digya national parks (Ghana). Numbers in the Akagera National Park, where its last-known populations in Rwanda exist, have seen a steep fall.[3]
Though populations have substantially decreased in western Africa, bohor reedbuck still exist in Niokolo-Koba National Park (Senegal); Corubal River (Guinea-Bissau); Kiang West National Park (Gambia);[20] Arly-Singou and Nazinga Game Ranch (Burkina Faso). Larger numbers occur in eastern and central Africa, mostly in protected areas such as Bouba Ndjida (Cameroon); Manovo-Gounda St. Floris National Park (Central African Republic); Bale Mountains National Park (Ethiopia); Murchison Falls National Park and Pian Upe Wildlife Reserve (Uganda); Maasai Mara (Kenya); Serengeti National Park, Moyowosi-Kigosi and Selous Game Reserve (Tanzania).[17]

I maschi hanno corna robuste, divergenti verso l'esterno, con una curvatura all'indietro seguita da una controcurvatura in avanti, per una lunghezza complessiva di circa 40 cm.
Le cervicapre vivono soprattutto nei terreni erbosi vicino all'acqua. Si nutrono in genere di erba, ma durante la stagione secca si possono adattare ad altri alimenti vegetali; nei pressi di fattorie sono state anche viste nutrirsi di grano e altri cereali.
Le cervicapre vivono in coppie o in gruppi familiari, sporadicamente in grandi branchi. Sono territoriali ma anziché marcare il territorio con segnali odorosi (come altre antilopi) dichiarano il proprio possesso emettendo dei versi molto peculiari, simili a fischi o gracidii di rane. Sono animali diurni, ma si ritirano all'ombra nelle ore più calde.
La gestazione dura 220 giorni e il parto è uniparo. La vita media della cervicapra è di 10 anni.
La cervicapra redunca o semplicemente cervicapra (Redunca redunca) è un'antilope dell'Africa centrale. In inglese viene chiamata Bohor reedbuck, in swahili tohe.
De bohorrietbok (Redunca redunca) is een middelgrote antilope uit het geslacht der rietbokken (Redunca).
De bohorrietbok heeft een rossige zandkleurige vacht. De onderzijde is grijzig wit van kleur, evenals de wangen, lippen, kin, keel, de binnenzijde van de oren en een kring rond de ogen. De neus en het midden van de lip zijn zwart. De korte staart is wit aan de onderzijde. Mannetjes zijn steviger gebouwd dan vrouwtjes. Enkel het mannetje heeft hoorns. Deze zijn liervormig en zeer geringd, voornamelijk rond de basis.
De bohorrietbok heeft een kop-romplengte van 100 tot 135 centimeter en een schouderhoogte van 65 tot 89 centimeter. De staart is 18 tot 20 centimeter lang. Mannetjes zijn zwaarder dan vrouwtjes. Mannetjes wegen 43 tot 65 kilogram, vrouwtjes 35 tot 45 kilogram.
De bohorrietbok komt voor van Senegal tot Ethiopië, zuidwaarts tot het Tanganyikameer en de vallei van de Ruvuma-rivier. Hij leeft voornamelijk op vochtige, open vlakten. Hij heeft een voorkeur voor drassige grasvlakten, als uiterwaarden rond meren (bijvoorbeeld Victoriameer, Tsjaadmeer) en rivieren (bijvoorbeeld de Nijl en de Niger). Deze grasvlakten kunnen in het regenseizoen overstromen en in de droge tijd te geteisterd worden door droogte en branden.
De bohorrietbok eet voornamelijk gras. De soort is meestal de gehele dag door actief, maar graast voornamelijk 's nachts. Tijdens het nachtelijke foerageren kan een rietbok tot acht kilometer van hun woongebied afdwalen. In de droge tijd, als de kwaliteit van het voedsel minder wordt, grazen sommige rietbokken ook overdag. Op het heetst van de dag zoekt hij de schaduw op in hoog gras of in struikgewas.
De bohorrietbok leeft meestal in paren of in kleine familiegroepen van drie tot zes dieren. De dieren communiceren met elkaar door middel van een hard fluitend geluid. Dit is voornamelijk 's nachts te horen in de droge tijd, waarbij hele fluitkoortjes te horen zijn. Bij gevaar wordt de staart omhoog gehouden, waardoor de witte onderzijde goed zichtbaar is. In de regentijd leven de meeste dieren in aparte woongebieden, die meestal overlappen. Ook mannetjes tolereren andere mannetjes in hun woongebied. In de droge tijd leven de dieren meer groepsgewijs. Mannetjes vormen dan kleine, tijdelijke territoria.
Tijdens de paartijd, aan het einde van de droge tijd, vechten de mannetjes regelmatig om te mogen paren met één of meerdere vrouwtjes. Tijdens de balts loopt het mannetje om het vrouwtje heen, waarbij hij een blatend geluid maakt. Na een draagtijd van zeven maanden wordt één jong geboren. De meeste jongen worden in de regentijd geboren. Het jong houdt zich de eerste twee maanden verborgen. Hij verandert dagelijks van schuilplaats. Vrouwtjes zijn na een jaar geslachtsrijp, mannetjes pas na vier jaar. Voor die tijd vormen mannetjes soms vrijgezellengroepjes. De bohorrietbok wordt ongeveer tien jaar oud.

Multimedia w Wikimedia Commons Ridbok zwyczajny[3], dawniej także: bohor[4] (Redunca redunca) – gatunek średniej wielkości antylopy, ssaka parzystokopytnego z rodziny wołowatych.
Obecny zasięg występowania gatunku obejmuje Afrykę środkową i wschodnią – od Senegalu po centralną Etiopię i na południe do północnej części Demokratycznej Republiki Konga, Rwandy, Burundi i Tanzanii.
Jego siedliskiem są nizinne i górskie podmokłe tereny porośnięte trawą i trzciną.
Dymorfizm płciowy jest wyraźnie zaznaczony. Samce mają rogi, są cięższe i większe – osiągają w kłębie 75 – 90 cm, samice 65 – 76 cm. Samice mają dwie pary sutków i nie mają rogów. Ubarwienie obydwu płci od żółtawego po czerwonopłowe z białym spodem. Rogi samców, z licznymi, poprzecznymi zgrubieniami osiągają długość 20-41 cm. Wierzchołki rogów skierowane są do przodu. Owłosiony ogon jest od spodu jaśniejszy.
Żyją pojedynczo, parami lub tworzą luźne stada. Zajmowane terytoria nie są znaczone zapachami. Ridboki zwyczajne regulują relacje sąsiedzkie za pomocą sygnałów głosowych. Obszar zajmowany przez samca może obejmować areały osobnicze kilku samic. Agresja samców skierowana jest bardziej na osobniki zagrażające samicom, niż naruszające zajmowane terytorium.
Samice z młodymi formują grupy na obszarach z niewystarczającą ilością dostępnych kryjówek. Młode dorastają wewnątrz obszaru matki, po czym młode samce łączą się w grupki 2-3 osobników. Starsze samce zwykle wędrują samotnie.
W okresie suszy grupy ridboków zwyczajnych łączą się w większe stada w pobliżu źródeł wody. Takie zgrupowania mogą liczyć setki osobników.
Ridboki zwyczajne są zwierzętami roślinożernymi. Żywią się głównie trawami. Spotykano je na uprawach zbóż.
Samice ridboka zwyczajnego osiągają dojrzałość płciową w wieku około 2 lat, czasem wcześniej, a samce w wieku 3 lat. Po 7,5-miesięcznej ciąży samica rodzi jedno, rzadko dwa młode, które przez osiem tygodni pozostają w ukryciu, a następnie formują grupy rówieśnicze. Przez 8-9 miesięcy utrzymują silne więzi z matką. Młode po urodzeniu mają ciemniejsze niż rodzice ubarwienie i dłuższe owłosienie.
Z powodu cenionego przez myśliwych poroża ridboki zwyczajne były w przeszłości poławiane przy użyciu psów naganiających te zwierzęta w sieci.
W Czerwonej księdze gatunków zagrożonych Międzynarodowej Unii Ochrony Przyrody i Jej Zasobów został zaliczony do kategorii LC (last concern – niższego ryzyka)[2].

Bohorrörbock (Redunca redunca) är en art i släktet rörbockar som lever i Afrika.
Bohorrörbocken är en medelstor antilop med en mankhöjd på mellan 70 och 90 centimeter och en vikt på upp till 55 kilogram. Hanarna är större än honorna och bär till skillnad från honorna horn. Dessa kan bli upp till omkring 40 centimeter långa och har en spets som pekar framåt. Pälsen är rödbrunaktig till gråbrunaktig med ljusare vit undersida. På frambenen finns svarta teckningar.
Bohorrörbocken har vid utbredning i centrala Afrika, och förekommer på skogklädda savanner och flodslätter från norra Senegal, Gambia och sydvästra Mauretanien och vidare österut till Etiopien. Från Etiopien förekommer den söderut till Tanganyikasjön och Ruvumafloden i Tanzania.
Bohorrörbocken betraktas som livskraftig av IUCN och sammantaget uppskattas det finnas något över 100 000 individer, men populationstrenden för artern är generellt sett nedåtgående, med undantag för några skyddade områden i östra Afrika.
Bohorrörbocken kan leva ensam eller i små grupper, men under torrperioden kan djuren även bilda större flockar. Den föredrar regelbunden tillgång till vatten och födan består huvudsakligen av gräs. Honan föder vanligen endast en unge per dräktighet.

Охранный статус
Обыкновенный редунка[1], или болотный козёл[1][2], или нагор[1] (лат. Redunca redunca) — антилопа, наиболее известный вид рода редунка, или тростниковых козлов (подсемейства водяных козлов семейства полорогих).
Обыкновенный редунка — антилопа небольшой величины. Высота в холке — 65-90 см, вес не превышает 65 кг (обычно намного меньше, в среднем примерно 45 кг)[3]. Это животное изящного сложения, с высокими ногами и пушистым хвостом. Он окрашен довольно ярко — общий окрас жёлто-бурый, брюхо белое. Белые пятна есть также у основания ушей. Пониже ушей, как и у других представителей рода — хорошо заметное тёмное пятно.
Рога только у самцов. Они сравнительно короткие — до 41 см[3], загнутые вперёд.
Обыкновенный редунка обитает практически по всей Африке к югу от Сахары. Исторический ареал этой антилопы чрезвычайно велик, но в настоящее время сильно разорван. Сейчас редунка в сколь-либо значительном числе обитает только там, где сохранились обычные для него условия — саванны и редколесье с большим количеством водоёмов.
Обыкновенный редунка многочислен в ряде мест Западной и Центральной Африки, в том числе бассейне Конго. Есть устойчивые популяции в Восточной Африке, особенно в Танзании. В целом этот вид считается вне угрозы. Статус вида, согласно Международной Красной книге, — «находящийся под небольшой угрозой» (LC — Least Concern; это самая низкая категория, означающая, что вид вне опасности).
Численность, тем не менее, снижается, за исключением восточной части ареала, где поголовье растёт. Общее количество оценивается чуть больше, чем в 100 тыс. голов[4]. Главная причина — разрушение среды обитания, а также неконтролируемый отстрел в неблагополучных странах Западной Африки, где государство не в силах наладить природоохранные мероприятия.
Обыкновенный редунка встречается на разнообразной местности. Его можно встретить и в сухих саваннах, но всё же он предпочитает более влажные места, ближе к водоёмам. Наиболее типичный его биотоп — редколесье и пойменные луга, где доступ к воде обеспечен в течение круглого года, даже в сухой сезон.
В некоторых частях ареала, например, в крайней северо-восточной, обыкновенный редунка встречается в гористой местности до высоты 3200 м. Там его ареал пересекается с ареалом горного редунки (лат. Redunca fulvorufula).
По образу жизни схож с другими редунками (большим и горным). Утром и вечером пасётся, а днём лежит в траве. Во время кормёжки удаляется до 8 км от места дневного укрытия[5].
При опасности затаивается, но в случае обнаружения врагом спасается стремительным бегством. В других случаях редунка, завидя хищника, начинает высоко подпрыгивать на месте, издавая пронзительный свист. Этот свист — один из характернейших звуков саванны — служит сигналом тревоги для всех зверей, находящихся поблизости[6].
Период размножения не связан с определённым сезоном. Беременность длится около 7 месяцев, после чего рождаются один или два телёнка, которые до двухмесячного возраста ведут себя скрытно, неподвижно притаиваясь в траве. Молодняк держится близ матери 8—9 месяцев. Половозрелость самцов наступает в три года, самок — в два[3].

葦羚（學名Redunca redunca）是一種生活於中非的羚羊，大部份生活於近水的草原。牠們的毛皮是紅色，在尾部較淺色，而腹部呈白色。雄性有著彎曲向前的角，這對角重約55公斤。
葦羚是小群生活，一群葦羚數量很少，甚至可能是獨居。牠們位於中非其中一種在日間活躍的動物，但在日間最高溫期間牠們則會躲到較涼的地方。
雄性葦羚有獨特的呼叫聲，而雌性則有著像青蛙的嗄聲。牠們的妊娠期為7.5個月。
