Benfontein is a De Beers’ property located c. 10 km south-east of Kimberley. The property is 11,300 ha in size (28o50′; 24o50′). The Northern Cape – Free State provincial boundary runs through the property. There is a complex network of roads on Benfontein, but the visitor is unlikely to get lost as the homestead and surrounds are visible from most parts of the farm. Although the roads are regularly graded they become impassable after even a few millimetres of rain. Three major vegetation biomes converge in the Kimberley area, with elements of these occurring on Benfontein, including mixed grassland, Kalahari thornveld (now known as Kimberley Thorn Bushveld) and Karoo (Eastern Mixed Nama Karoo).
Benfontein is perhaps one of the prime birding localities in the western Free State. This is partly due to the large diversity of bird species that frequent the property as a result of the diverse habitat types, but also because of the knowledge that has been gained through several ornithological research projects about the property’s avifauna. Thus far 260 bird species have been recorded on Benfontein. Over the years the property has become well known for its larks, and 12 species have been recorded, including Monotonous Lark, Pink-billed Lark and Black-eared Sparrowlark. Pipits too are not uncommon, with five species being recorded. The Kimberley and Long-tailed Pipits, two species that were described by Dr Richard Liversidge from specimens collected in the Kimberley area, have also been recorded on Benfontein.
It is however perhaps the Kalahari and Nama Karoo endemics that are the property’s main attraction, particularly for overseas bird-watchers who occasionally visit Benfontein. These include: Orange River Francolin, Bradfield’s Swift, Ludwig’s Bustard, Blue Korhaan, Burchell’s and Namaqua Sandgrouse, Burchell’s Courser, Crimson-breasted Shrike, Cape Penduline-Tit, Fairy Flycatcher, Rufous-eared Warbler, Eastern Clapper Lark, Marico Flycatcher, Kalahari Scrub-Robin, Mountain Wheatear, Violet-eared Waxbill, Cape Longclaw and Kimberley Pipit. There are at least 40 Sociable Weaver colonies in camel thorn trees in the south-eastern areas of the property. Associated with these nests are other typical Kalahari bird species, such as Pygmy Falcon, Acacia Pied Barbet, Ashy Tit and Red-headed Finch.
There is a population of c. 20 pairs of African White-backed Vultures that breed on top of Acacia erioloba trees. Cape Vultures and Lappet-faced Vultures are also occasionally observed roosting on the powerline that traverses the eastern section of the property, or at wild animal carcasses. The greater Kimberley area in fact supports a breeding population of more than 250 pairs of White-backed Vultures. These have been the focus of intensive research during the past 13 years, with more than 500 birds being ringed. Please record the combination of colour-rings on ringed birds and send the details to the Northern Cape Department of Tourism, Environment & Conservation. Several others species of raptors breed on the farm, including Tawny Eagle, Secretarybird, Greater Kestrel, and Verreaux’s Eagle-Owl. Less frequent visitors are Red-footed and Amur Falcon, Montagu’s and Pallid Harrier, and African Grass-Owl.
The world’s largest bird, the Common Ostrich, is common on Benfontein and these birds are most well-known for their genetic integrity. In other words these southern Ostriches Struthio camelus australis have not hybridized with Ostriches introduced to South Africa from other parts of the African continent. Other large birds, which are sometimes encountered on Benfontein, include Blue Cranes (which breed during the summer months) as well as several species of bustard, most notably Ludwig’s Bustard, Northern Black Korhaan and Red-crested Korhaan. The dolerite hills on the southern and western extremities of the property provide habitat for a unique suite of birds, including African Rock Pipit, Long-billed Pipit, Layard’s Tit-Babbler, Grey-backed Cisticola, and Short-toed Rock-Thrush.
The large ephemeral pan in the low-lying northern end of the property can support a plethora of interesting waterbirds. After inundation in 1988, the pan held water for more than three years. After the subsequent inundation event in March 2003, the population of waterbirds that frequented this wetland was monitored, with the results of this interesting study being published in Ostrich (Herrmann et al. 2004). Some interesting waterbirds which have been recorded at the pan include: Black-necked Grebe, Purple Heron, Greater and Lesser Flamingo, Hottentot Teal, Southern Pochard, Greater Painted-Snipe, and various species of waders, including Common Greenshank and Pied Avocet. The homestead, picnic site, and farm dam support an interesting suite of birds, including Barn Owl, Brown-hooded Kingfisher, Swallow-tailed Bee-eater, Green Wood-hoopoe, Crested Barbet, Lesser and Greater Honeyguide, Familiar Chat, and White-bellied Sunbird.
Directions
The entrance to Benfontein is about 8 km from Kimberley’s Honoured Dead Memorial (or 5 km from the airport turnoff), on the western side of the Kimberley–Bloemfontein N8 road, with the entrance at the provincial border.
Facilities
There are camping facilities at Benfontein. Research facilities are available in an historic Victorian-style house, but this is only for bona fide research projects. Excellent accommodation is available at a variety of establishments in Kimberley, from bed and breakfasts to hotels.

Additional Information
Benfontein has an interesting diversity of large ungulates that are typical of the Free State and Northern Cape. These include Steenbok, Grey Duiker, Springbok, Mountain Reedbuck, Kudu, Blesbok, and Black Wildebeest. The latter two species are of conservation importance as they are genetically pure, having never seen the closely-related Bontebok and Blue Wildebeest. Surplus ungulates captured on Benfontein have been used to re-establish populations of these species on other properties throughout the country. The farm is also well known for its diversity of nocturnal animals and a night time drive can be particularly rewarding with frequent observations of Aardwolves, Aardvark, Black-footed Cat, Hedgehog, Cape Fox, Bat-eared Fox, Black-backed Jackal, Small-spotted Genet, Springhare, and Cape Porcupine. Even some of the smaller rodents, such as the Large-eared Mouse Malacothrix typica, are of interest.
A large diversity of plants is found on Benfontein, with a few unusual and threatened plants, including one member of the Mesembryanthemaceae, Nananthus species, amaryllids namely vleilelie Nerine laticoma, gifbol Ammocharis coranica, seeroogbol Boophone disticha and the poisonous iris, bloutulp Moraea polystachya. As a result of its biological and cultural importance, Benfontein Game Farm was designated as a Natural Heritage Site in the mid-1980s. It is also listed as an Important Bird Area, with 16 endemic and near-endemic bird species occurring on the property.
The Paleohydrology, geology and archaeology of Benfontein have been the focus of several studies. Although kimberlite pipes are found on the farm, the deposits are small and thus not economically viable and consequently diamonds have not been mined.
The margins of the Alexandersfontein Pan are renowned in the annals of archaeology for the rich spreads to be found there of Stone Age and palaeoenvironmental traces. There is evidence of a palaeolake of substantial proportions, and numerous sites with Middle Stone Age artefacts have been documented. Later Stone Age rock engravings occur in the hills to the north of the pan. In 1858 conflict flared up when Khousop, a local KhoeSan leader, said to have resided at Wildebeest Kuil, attacked white settlers at Benfontein farm.
