The
micro-habitats of the Soutpansberg mountain range are home to highly
diverse animal communities, with over 60% of of mammal species found
in South Africa recorded in the mountains with an an especially rich
carnivore community. Large carnivore species that range in the mountains
are leopard (Panthera pardus), brown hyaena (Hyaena brunnea)
and spotted hyaena (Crocuta crocuta), with leopards particularly
abundant around Lajuma. Smaller carnivore species include African civet
(Civettictis civetta), common genet (Genetta genetta),
aardwolf (Proteles cristatus), honey badger (Mellivora capensis),
caracal (Felis caracal), African wildcat (Felis silvestris),
serval (Leptailurus serval), Cape clawless otter (Aonyx capensis)
and several mongoose species; water mongoose (Atilax paludinosus).
dwarf mongoose (Helogale parvula), slender mongoose (Galerella
sanguinea) and banded mongoose (Mungos mungo). Cheetah (Acinonyx
jubatus) are no longer found on the mountain plateau and lions (Panthera
leo) only remain in the far eastern part of the Soutpansberg (Gaigher
& Suart 2003).
The
Soutpansberg mountain range also hosts 56% of South Africa's bird species,
including a large diversity of birds of prey. Of particular interest
are crowned eagle (Stephanoaetus coronatus), Verreaux's eagle
(Aquila verreauxii) and Verreaux's eagle owl (Bubo lacteus)
since all are confirmed or potential predators of primates in our study
area.
Our
current and future carnivore work predominantly focusses on the following
species.
Leopard
Panthera
pardus
Leopards
(Panthera pardus) have the largest distribution of any
wild felid, occurring widely in eastern and central Africa, although
populations are declining and fragmented outside of sub-Saharan
Africa. Within sub-Saharan Africa, the species is still numerous
and even thriving in marginal habitats where other large cats
have disappeared. Nevertheless, because of its declining range
and population, leopards are listed as "Near Threatened"
by the IUCN. Leopards have a broad habitat tolerance and in Africa
they are most successful in woodland, grassland savanna and forest,
but also occur widely in mountain habitats, coastal scrub, swampy
areas, shrubland, semi-desert and desert. Leopards are elusive,
solitary and largely nocturnal, and male territories are generally
larger than those of females. They are versatile, opportunistic
hunters, and have a very broad diet. Leopards feed on anything
from dung beetles to male giant elands (900kg). Their diet consists
mostly of ungulates and monkeys, but they also eat rodents, reptiles,
amphibians, insects, birds, and fish. Leopards hunt by stalking,
and in Africa mid-sized antelopes provide a majority of their
prey. Densities vary with habitat, prey availability, and degree
of threat, from fewer than one per 100 km² to over 30 per
100 km². The Soutpansberg supports one of the highest densties
of leopards recorded anywhere in Africa.
Brown
hyaena
Hyaena
brunnea
Brown
hyaena (Hyaena brunnea) are endemic to southern Africa,
aqlthough their distribution is fragmented across their range.
Brown hyaenas are found in the drier areas and savannahs where
they can survive with very little water; often areas with less
than 100mm of annual rainfall, although they may inhabit woodland
savannah with a maximum annual rainfall of 650mm. They regularly
use rocky areas for shelter and dens. Brown hyenas are smaller
than spotted hyaenas with an adult body weight of approximately
40kg, and little difference in size between the sexes. Brown hyena
are primarily a scavenger of mammal remains, but their diet has
also been found to include insects, birds, eggs and fruit. Hunting
comprises a relatively small proportion of the brown hyaena's
foraging behaviour, but small mammals and birds are occasionally
predated, although they are not thought to be a major threat to
livestock. Brown hyaenas live in small social groups called clans
which range in size from a solitary female and her cubs to groups
containing several females and their offspring of different ages.
Adult males either remain with their natal clan, become nomadic,
or immigrate into a new clan. The clan cooperatively defends a
territory, but its members of a clan forage on their own. Much
of the communication among brown hyaenas, from greetings to territorial
markings involves use of chemical signals.
African
Civet
Civettictis
civetta
The
African Civet (Civettictis civetta) is the largest representative
of the African Viverridae (weight range 9-15kg) and the sole member
of its genus. African civets are widely distributed across sub-Saharan
Africa and are found in a wide variety of habitats from thick
forest to open country. They are primarily nocturnal and spend
the day sleeping in dense vegetation, becoming active at night.
The African civet is a solitary mammal that is easily recognizable
by its unique coloration; the black and white stripes and blotches
covering the coarse pelage of the animal are extremely variable
and allow it to be cryptic. Thes civets are omnivorous generalists,
taking small vertebrates, invertebrates, eggs, carrion, and vegetable
matter. They are also capable of taking on poisonous invertebrates
(such as the millipedes most other species avoid) and snakes.
Prey is primarily detected by smell and sound rather than by sight.
Like all civets the African civet has perineal glands that produce
a fluid known as civetone, which it spreads on markers in its
territory to claim its range.
Common
Genet
Genetta
genetta
The
Common Genet (Genetta genetta), is the most widely distributed
of the fourteen species of genet, with a natural range across
Africa and parts of the Middle East. A secretive, nocturnal species,
the common genet inhabits rocky terrain with caves, dense scrubland,
pine forests, and marshland. The species has a pale grey and black
spotted coat, with a long striped tail. Like all genets, it has
a small head, large ears and eyes, and short legs with retractable
claws. Common genets weighs between 1.5 and 2.5kg and males are
larger than females. They are excellent climbers although much
of their foraging is done on the ground. Common genets has a varied
diet, that consists of small mammals, lizards, birds, amphibians,
insects and fruit.
African
Crowned Eagle
Stephanoaetus
coronatus
The
African crowned eagle (Stephanoaetus coronatus), is a very
large (wingspan 1.5-1.8 metres), powerful, crested bird of prey
found in sub-Saharan Africa. It inhabits dense forests, heavily
wooded hillsides, dense woodland and rocky outcrops, although
owing to lack of suitable habitat, the eagle's range is discontinuous
across its distribution. The crowned eagle is non-migratory and
is largely sedentary, usually inhabiting a fixed territory for
most of its lifespan. Crowned eagle pairs breed once every two
years (a single breeding cycle is approximately 500 days) and
build massive nests in a fork of large, emergent trees. The nest
may be re-used during successive breeding seasons. The crowned
eagle's staple diet is mostly mammalian, with primates being the
most commonly taken prey. In suitable habitat it will also take
hyraxes and small antelope such as duikers. Typically, the eagle
can carry a mass roughly equal to its own (~ 36 kg) to its
nest or perch; anything heavier is dismembered and returned to
the nest or perch in pieces. Parts of larger prey are often cached
for later consumption.
Verreaux's
Eagle
Aquila
verreauxii
Verreaux's
eagle (Aquila verreauxii), sometimes known as the black
eagle, inhabits hilly and mountaineous regions of southern and
eastern Africa. It is a large eagle with a wingspan of up to 2.2
metres, and an average weight for males of 3.7 kg and 4.5 kg for
females. It is black with a distinct white V marking on its back,
while juveniles are usually light and dark brown with a black
face. Verreaux's eagle are highly territorial and can often be
seen with a mate since the birds are thought to mate for life.
Verreaux's eagle specialist hunters of hyraxes (or dassies), and
the size of their territory is generally inversely proportional
to the size of the local hyrax population. Occasionally, however,
these eagles will prey on birds such as guineafowl or mammals
of similar size to hyraxes, such as large rodents or primates.
