4-6-2019 LINYANTI CAMP, BOTSWANA - COMMON SLENDER MONGOOSE (Herpestes sanguineus)
The common slender mongoose (Herpestes sanguineus), also known as the black-tipped mongoose or the black-tailed mongoose, is a very common mongoose species native to sub-Saharan Africa.
As the name suggests, the common slender mongoose has a lithe body of 27.5–40 cm (10.8–15.7 in) and a long tail of 23–33 cm (9.1–13.0 in). Males weigh 640–715 g (22.6–25.2 oz), while the smaller females weigh 460–575 g (16.2–20.3 oz).
The color of their fur varies widely between subspecies, from a dark reddish-brown to an orange red, grey, or even golden yellow, but these mongooses can be distinguished from other mongooses due to the prominent black or red tip on their tails. They also have silkier fur than the other African members of their family.
The common slender mongoose occurs throughout sub-Saharan Africa, where it is most common in the savannah and semiarid plains, but rarely recorded in densely forested areas and deserts.
The common slender mongoose generally lives either alone or in pairs. It is primarily diurnal, although it is sometimes active on warm, moonlit nights. It doesn't seem to be territorial, but will nevertheless maintain stable home ranges that are often shared with members of related species. Indeed, the common slender mongoose and these other species may even den together, as most of their relatives are nocturnal. Dens may be found anywhere sheltered from the elements: in crevices between rocks, in hollow logs, and the like.
A male's range includes the ranges of several females, and scent cues inform him when the female is in heat. The gestation period is believed to be 60 to 70 days, and most pregnancies result in one to three young. The male does not help care for them. Unusually, for a solitary species, in the Kalahari Desert the males are philopatric whereas the females disperse.
The common slender mongoose is primarily carnivorous, though it is an opportunistic omnivore. Insects make up the bulk of its diet, but lizards, rodents, snakes, birds, amphibians, and the occasional fruit are eaten when available. It will also eat carrion and eggs. As befits the popular image of mongooses, the slender mongoose is capable of killing and subsequently eating venomous snakes, but such snakes do not constitute a significant portion of its diet.
Common slender mongooses are more adept at climbing trees than other mongooses, often hunting birds there. White browed-sparrow weavers, crimson breasted shrikes, and glossy starlings are considered common prey.
4-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN HAWK EAGLE (Aquila spilogaster)
The African hawk-eagle (Aquila spilogaster) is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. This species’ feathered legs mark it as a member of the Aquilinae subfamily. The African hawk-eagle breeds in tropical Sub-Saharan Africa. It is a bird of assorted woodland, including both savanna and hilly areas but the tend to occur in woodland that is typically dry. The species tends to be rare in areas where their preferred habitat type is absent. This species builds a stick nest of around 1 m (3.3 ft) across in a large tree. The clutch is generally one or two eggs. The African hawk-eagle is powerfully built and hunts small to medium sized mammals and birds predominantly, occasionally taking reptiles and other prey as well. The call is a shrill kluu-kluu-kluu. The African hawk-eagle is considered a fairly stable species and a species of Least Concern per the IUCN.
The African hawk-eagle is uncommonly aggressive and bold predator. Their primary hunting tool is their powerful feet. In general, their sneaky foraging techniques recall a huge Accipiter. In terms of agility and hunting prowess, especially in terms of their short-distance flight after prey, they are also somewhat reminiscent of an Accipiter. Mostly the African hawk-eagle engages in still-hunting, wherein they scan from prey from an inconspicuous perch for a long period. When prey is spotted, the hawk-eagle engages in a low level dash from their perch in cover. They often uses cover to cloak their approach almost up the point where they strike. While it has been claimed that their flight is “silent”, it would presumably be more correct to say that the hunting hawk-eagle engages in minimal flapping flight so as to not alert prey to their approach. Often, the hawk-eagles wait near prey-concentrated areas, such as waterholes and among riparian trees for birds to come to drink or by clearings that birds frequently cross. African hawk-eagles may too quarter above the ground and seize any prey they surprise. They are capable of sometimes taking birds on the wing but usually prefer to catch them on the ground and may force avian prey intercepted in the air back to the ground. Often terrestrial birds are taken right around the moment they alight. In some instances, prey may be chased, even on foot, into thickets. African hawk-eagles have seldom been recording engaging a stoop from soaring flight to capture prey. Pairs of African hawk-eagles often hunt together and in these circumstances seem to engage in deliberate cooperation, one distracting, the other striking. They share this tendency for hunting in pairs with their sister species, the Bonelli's eagle, which has been implied to engage in tandem hunts possibly for sociosexual pairing reasons rather than for obtaining larger or more difficult prey, as is typically assumed of tandem-hunting raptors. One tandem hunting pair of African hawk-eagles appeared to remarkably make use of a mesh fence to drive guineafowl into in a cunning strategy to prevent their escape. Yet another pair of African hawk-eagles appears to derive much of its prey by regularly and opportunistically perching in a tree holding a fruit bat colony.
4-6-2019 LINYANTI, BOTSWANA - COMMON BULBUL (Pycnonotus barbatus)
%20%2021.jpg)
The common bulbul (Pycnonotus barbatus) is a member of the bulbul family of passerine birds. It is found in north-eastern, northern, western and central Africa.
The bill is fairly short and thin, with a slightly downwards curving upper mandible. The bill, legs, and feet are black and the eye is dark brown with a dark eye-ring, which is not readily visible. It is about 18 cm in length, with a long tail. It has a dark brown head and upperparts. Sexes are similar in plumage.
It is a common resident breeder in much of Africa, and it has recently been found breeding in southern Spain at Tarifa. It is found in woodland, coastal bush, forest edges, riverine bush, montane scrub, and in mixed farming habitats. It is also found in exotic thickets, gardens, and parks.
The common bulbul is usually seen in pairs or small groups. It is a conspicuous bird, which tends to sit at the top of a bush. As with other bulbuls they are active and noisy birds. The flight is bouncing and woodpecker-like. The call is a loud doctor-quick doctor-quick be-quick be-quick.
This species nests throughout the year in the moist tropics, elsewhere it is a more seasonal breeder with a peak in breeding coinciding with the onset of the rainy season. The nest is fairly rigid, thick-walled and cup-shaped. It is usually situated inside the leafy foliage of a small tree or shrub.
Two or three eggs are a typical clutch. Like other bulbuls, it is parasitised by the Jacobin cuckoo.
This species eats fruit, nectar, seeds and insects.
The Common Bulbul (Pycnonotus barbatus) is a widespread, adaptable African bird known for its bold, noisy nature, diverse omnivorous diet (fruits, insects, nectar), and distinctive dark-hooded look with pale underparts, often found in gardens and woodlands; they are vocal, territorial, and comfortable near humans, often mobbing predators and nesting in bushes.
Key Facts:
Appearance: Brownish-grey body, dark brown head with a slightly crested look, black bill, legs, and eye; some subspecies have yellow undertail coverts.
Size: Medium-sized, about 18-20 cm long with a long tail, similar in plumage for both sexes.
Habitat: Highly adaptable, living in woodlands, savannahs, gardens, parks, and urban areas across much of Africa.
%2020.jpg)

4-6-2019 LINYANTI CAMP, BOTSWANA - ARNOT'S CHAT (Myrmecocichla arnotti)
Arnot's chat (Myrmecocichla arnotti), also known as the white-headed black-chat, is a species of bird in the chat and flycatcher family Muscicapidae. The species is found in southern Africa from Rwanda and Angola to South Africa.
Arnot's chat is most commonly found in healthy stands of miombo and mopane woodland. It also occurs at lower densities in other kinds of open woodland with little herbaceous cover, and very rarely near buildings. It generally occurs from sea level to 1,500 m (4,900 ft). The species is generally not migratory, but is presumed to undertake some localized wandering.
