African Derter


This species builds a stick nest in a tree and lays 3-6 eggs. It often nests with herons, egrets and cormorants.
It often swims with only the neck above water, hence the common name snakebird. This too is a habit shared with the other anhingas.
Unlike many other waterbirds the feathers of the African Darter do not contain any oil and are therefore not waterproof. Because of this, the bird is less positively buoyant and its diving capabilities are enhanced. After diving for fish, the feathers can become waterlogged. In order to be able to fly and maintain heat insulation it needs to dry its feathers. Thus the African Darter is often seen sitting along the waterside spreading its wings and drying its feathers in the wind and the sun along with cormorants which may share its habitat.

Acacia Pied Barbert.


Like most other barbets, the Acacia Pied Barbet drills holes into dead wood in order to create cavity nests, similar in manner to a woodpecker. It lays two to four eggs from August to April, and both sexes incubate the eggs.
The Acacia Pied Barbet has been observed taking fruit from various trees and shrubs, such as Ficus, Rhus and Phoenix reclinata, as well as Aloe nectar and insects.



Impalas are an ecotone species living in light woodland with little undergrowth and grassland of low to medium height. They have an irregular distribution due to dependence on free water, soils with good drainage with firm footing and moderate or less slope. While they are usually close to water in the dry season, they can go weeks without drinking when they have access to green vegetation.
Impalas are adaptable foragers. They usually switch between grazing and browsing depending on the season. During wet seasons when grasses are green and growing they graze. During dry seasons it browses foliage, shoots, forbs and seeds. It can also adapt to different habitats by being a grazer in one habitat a browser in another. Leopards, cheetahs, lions and wild dogs prey on impala.

Impala, as well as other small- to medium-sized African antelopes, have a special dental arrangement on the front lower jaw similar to the toothcomb seen in strepsirrhine primates, which is used during grooming to comb the fur and remove ectoparasites.

Kirk's Dik Dik.

                                                             Kirk's Dik Dik                                                                                                                                                          Genetic and behavioural evidence suggests that Kirk's Dik-dik exhibits fidelity in monogamous behaviour. Genetic analysis of off-spring indicate little non-pair parentage. Year-round, Kirk's Dik-diks stay close within pairs, follow each other's activity patterns and spend more than half of their time with their partners, although males give no parental care. The males guard their mates closely during oestrus and over-mark all female scent. This behaviour reduces the likelihood of other males attempting to mate, however, males do attempt to mate with other females on occasion. Genetic monogamy in dik-diks is probably best explained by the behaviour of females: in contrast to many monogamous female birds, female dik-diks do not appear to seek to mate outside the pair-bond.

Baboons and Monkeys

Baboons are terrestrial (ground dwelling) and are found in open savannah, open woodland and hills across Africa. Their diet is omnivorous, but mostly herbivorous; yet they eat insects and occasionally prey on fish, shellfish, hares, birds, vervet monkeys, and small antelopes. They are foragers and are active at irregular times throughout the day and night. They can raid human dwellings and in South Africa they have been known to prey on sheep and goats.
Their principal predators are humans, the lion, both the spotted and striped hyena and the leopard. They are however considered a difficult prey for the leopard, which is mostly a threat to young baboons. Large males will often confront them by flashing their eyelids, showing their teeth by yawning, making gestures, and chasing after the intruder/predator.
Baboons in captivity have been known to live up to 45 years, while in the wild their life expectancy is about Baboons.

Social structure

The vervet monkey is diurnal and social; living in groups of up to 72. There is a clear order of dominance among individuals within the group.

Alarm calls

The vervet monkey uses different calls upon detecting different types of predators, including leopards, snakes and eagles. Infants appear to have an innate tendency to make these alarm calls, and adult monkeys seem to give positive reinforcement when their young make the right call, by repeating the alarm. Mothers have been reported to punish young giving the wrong call

4X4 From Kongoni Adventures

4X4 is considered to be any type ofvehicle which is capable of driving on and off paved or gravel surface. It is generally characterized by having large tires with deep, open treads, a flexible suspension.

The spectacle of predator versus prey dominates Tanzania’s greatest park. Golden-maned lion prides feast on the abundance of plain grazers. Solitary leopards haunt the acacia trees lining the Seronera River, while a high density of cheetahs prowls the southeastern plains. Almost uniquely, all three African jackal species occur here, alongside the spotted hyena and a host of more elusive small predators, ranging from the insectivorous aardwolf to the beautiful serval cat.

Oldupai Gorge and Kolo Rock Painting.

Kondoa Rock-Art Sites *


Kondoa Rock Art Sites is located in Tanzania
Location of Kondoa Rock Art Sites in Tanzania

The Kondoa rock art sites are a series of caves carved into the side of a hill looking out over the steppe, c. nine kilometres off the main highway from Kondoa to Arusha, about 20 km north of Kondoa, in Tanzania. The caves contain paintings, some of which are believed by the Tanzania Antiquities Department to date back more than 1500 years. The paintings depict elongated people, animals, and hunting scenes. Tourists are asked to report to the Antiquities Department office on the highway at the village of Kolo and ask for the cave paintings guide.

Olduvai Gorge, the archaeological site also known as "The Cradle of Mankind”, is a steep-sided ravine in the Great Rift Valley that stretches through eastern Africa. It is in the eastern Serengeti Plains in northern Tanzania and is about 48 km (30 mi) long. It is located 45 km from the Laetoli archaeological site. The name is a misspelling of Oldupai Gorge, which was adopted as the official name in 2005. Oldupai is the Maasai word for the wild sisal plant Sansevieria ehrenbergii, which grows in the gorge.[1]
Olduvai Gorge is one of the most important prehistoric sites in the world and has been instrumental in furthering the understanding of early human evolution. This site was occupied by homo habilis approximately 1.9 million years ago, paranthropus boisei 1.8 million years ago, and homo erectus 1.2 million years ago. Homo sapiens are dated to have occupied the site 17,000 years ago.
This site is also significant in showing increased developmental and social complexities in hominins. Evidence of this is shown in the production and use of stone tools, which indicates the increase in cognitive capacities. There is also evidence indicating the practices of both scavenging and hunting, which is highlighted by the evidence of gnaw marks predating cut marks, and comparisons on percentages of meat versus plant in the early hominid diet. Furthermore, the collection of tools and animal remains in a central area is evidence of increases in social interaction and communal activity.
