27-5-2019 SOMALISA CAMP, ZIMBABWE - MARICO FLYCATCHER (Bradornis mariquensi)
A large flycatcher with upright posture, plain brown upperparts with warm edges to flight feathers, and diagnostic and strongly contrasting bold white underparts. Juveniles are heavily streaked brown and white. Pairs and small groups inhabit arid scrub, favoring thorn trees, where they sit conspicuously on low perches, sallying or pouncing onto the ground to subdue prey. All other brown flycatchers in the same range have brown or buffy underparts.
The Marico flycatcher or Mariqua flycatcher (Bradornis mariquensis) is a passerine bird in the Old World flycatcher family Muscicapidae that is found in areas of southern Africa.
The Marico flycatcher was previously placed in the genus Bradornis but was moved to Melaenornis based on the results of a molecular phylogenetic study published in 2010.
It is found in Angola, Botswana, Namibia, South Africa, Zambia and Zimbabwe.
Its natural habitat is dry savanna.
This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence under 20,000 km² combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (under 10,000 mature individuals with a continuing decline estimated to be over 10% in ten years or three generations, or with a specified population structure). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (over 30% decline over ten years or three generations). For these reasons the species is evaluated as Least Concern.
27-5-2019 SOMALISA CAMP, ZIMBABWE - MAGPIE SHRIKE (Corvinella melanoleuca)
%2020.jpg)
The magpie shrike (Lanius melanoleucus), also known as the African long-tailed shrike, is a species of bird in the family Laniidae. It is native to the grasslands of eastern and southeastern Africa, where its natural habitats are dry savannah, moist savannah, and subtropical or tropical dry shrubland. It has a very wide range and is common in places, and the International Union for Conservation of Nature has assessed its conservation status as being of "least concern".
The magpie shrike is found in Angola, Botswana, Eswatini, Kenya, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe.[1] It inhabits open savannah with scattered acacia trees, close-grazed turf and bare ground, in parts of southern and central Africa where precipitation mainly occurs between November and April. Arid areas are avoided but semi-arid areas may be favoured. It also occurs in woodland, particularly riparian areas, and in the Kruger National Park is found in river valleys with thorny mopane trees.
27-5-2019 SOMALISA CAMP, ZIMBABWE - LILAC BREASTED ROLLER (Coracias caudatus)
%2020.jpg)
The Lilac-breasted roller (Coracias caudatus) is a beautifully colored African bird known for its acrobatic aerial displays during the breeding season. The sexes look similar, and juveniles lack the long tail streamers of adults. This species is unofficially considered the national bird of Kenya.
These large-headed birds are almost unmistakable with their colorful plumage tones. The lilac throat of the nominate subspecies C. c. caudatus deepens into a darker lilac breast. The crown to the mantle is olive, and the cheeks and ear coverts a lilac-rufous. In subspecies C. c. lorti however, the crown to mantle is greenish blue instead of olive, and the breast azure. The throat is lilac, and some Lilac-throated rollers have a lilac patch or rufous-brown tinges on the lower abdomen. Both subspecies have long, black outermost tail streamers that are absent in juveniles. The males and the females look alike though males may be slightly larger than females. Juveniles, immatures, and adults have the largest alula feather dark blue, but the primary coverts and rest of the alula are azure. The proximal half of the remiges are also a brilliant azure, and the distal half is black on the inner web, and dark purple-blue on the outer webs. Juveniles have the throat and breast rufous-tawny with broad diffuse buffy-white streaks with mauve margins on some feathers. Immatures have the breast buffy with occasional lilac feathers and diffuse pale streaking. Unique to rollers (family Coraciidae) are syndactyl feet, in which the second and third digits are fused.
%2021.jpg)
Lilac-breasted rollers are found throughout eastern and southern Africa. Their range extends from the Red Sea coast of Eritrea through East Africa (including Zanzibar) to southern Africa, where they occur commonly in Namibia (excluding the Namib Desert), Botswana, Zimbabwe, and northeastern South Africa. Some populations are non-migratory, while others migrate from northeast Kenya to northwest Somalia to breed from late April to mid-September. Lilac-breasted rollers live in open savannah habitats with scattered trees and shrubs. Less often they frequent riverine vegetation and light forest and may enter sub-desert steppe or open grassland where any elevated perches may be used. In protected areas, these birds frequent the verges of roads, especially during fires, but generally, they try to avoid other human-influenced areas and are not found in urban or rural areas.
%2022.jpg)
Lilac-breasted rollers are active during the day and are usually found alone or in pairs. They perch conspicuously at the tops of trees, poles, or other high vantage points from where they can spot insects, lizards, or other prey moving about on the ground. Lilac-breasted rollers hunt from a perch and scout from a higher vantage point (including from atop large herbivorous mammals) before swooping in and grabbing prey with their beaks. If their prey is small, they will swallow it on the ground. These aggressive birds will carry larger prey back to a perch and beat it until it is dismembered. Outside of protected areas such as national parks, Lilac-breasted rollers may often be seen when farmers burn land for agricultural use. Such brush fires stir up insects and other invertebrates, and birds can be seen swooping in for easy prey. In East Africa, they join other perch hunters like Taita fiscals and Pale flycatchers to make opportunistic use of grassland fires. In South Africa, they are also seen in association with kites, storks, swallows, and bee-eaters when the burning of firebreaks drives small animals onto roads. The call of these acrobatic fliers is a harsh, sawing 'rak rak rak' that is given during flight. They also produce loud raucous calls during flight displays and will perch to sing.
%2023.jpg)
Lilac-breasted rollers are monogamous birds believed to mate for life. Pairs nest solitary and are protective of their nest and one of the pair will fly in a rolling pattern as a territorial display against intruders or distract nest predators. During courtship, a Lilac-breasted roller will fly upwards and then tip forward with the wings closed, before flapping to gain speed towards the ground. While leveling out at the highest speed the bird will roll to the left and right a few times, uttering a harsh, raucous 'kaaa, kaarsh', before swooping up again. The display may end with a harsh chuckling. The breeding season occurs at various times of the year, depending on the location; in Somalia, these birds breed from late April to mid-September.
%2024.jpg)
They build flat nests of grass in a baobab, dead coconut, casuarina, or Terminalia tree. The nest is situated in a hollowed-out tree cavity some 5 meters (16 ft) off the ground, or even on the side of a termite mound. Lilac-breasted rollers do not create the cavities themselves but take over nest spaces that have been previously hollowed out by woodpeckers or kingfishers. Females lay 2-4 eggs per breeding season and both partners will take turns incubating the eggs for 22 to 24 days. Hatchlings are born altricial (helpless), becoming fully feathered after 18-20 days. They will remain dependent on their parents for up to another month and will be ready to breed at the age of 2 years.
27-5-2019 SOMALISA CAMP, ZIMBABWE - GUINEAFOWL BUTTERFLY (Hamanumida daedalus)
%2020.jpg)
The genus Hamanumida comprises of a single species – daedalus, which is popularly known as the Guineafowl due to its colour and pattern which resembles that of the guineafowl bird.
Hamanumida daedalus is widespread across Africa including Madagascar. It also occurs in the Arab states.
This is a grassland / savannah species found at altitudes between sea level and about 800m. It is associated mainly with dry, rocky grassland where there are scattered bushes and trees, but also rapidly colonises abandoned agricultural land.
The primary larval foodplant is Combretum, but Terminalia and Tectona (teak) are also used.
%2021.jpg)
The butterflies are normally seen singly or in two’s and three’s. Males will mud-puddle at the edges of fords and small streams, but both sexes are more commonly seen aggregating at the top of hills where courtship and copulation take place. They fly very low over the ground, and frequently settle to bask on bare ground or on rocks or boulders. At all times they remain very alert, taking flight at the slightest disturbance.
Hamanumida daedalus, the guineafowl butterfly, is a butterfly of the family Nymphalidae and only member of the genus Hamanumida.
It is found in the Afrotropical realm (Natal, Eswatini, Transvaal, Mozambique, Zimbabwe, Botswana, tropical Africa (dry lowland areas) and southwest Arabia).
The wingspan is 55–65 mm for males and 60–78 mm for females. Adults are on wing year-round, with peaks in midwinter and summer.
The larvae feed on Combretum and Terminalia species.
27-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN GREATER KUDU (MALE) (Tragelaphus Strepsiceros)
The greater kudu (Tragelaphus strepsiceros) is a large woodland antelope, found throughout eastern and southern Africa. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. The greater kudu is one of two species commonly known as kudu, the other being the lesser kudu, T. imberbis.
Kudu (/kuːduː/ koo-DOO), or koodoo, is the Khoikhoi name for this antelope. Trag- (Greek) denotes a goat and elaphos (Greek) a deer. Strepho (Greek) means 'twist', and strepsis is 'twisting'. Keras (Greek) refers to the horn of the animal.
Greater kudus have a narrow body with long legs, and their coats can range from brown/bluish grey to reddish brown. They possess between 4 and 12 vertical white stripes along their torso. The head tends to be darker in colour than the rest of the body, and exhibits a small white chevron which runs between the eyes. Greater kudu bulls tend to be much larger than the cows, and vocalize much more, utilizing low grunts, clucks, humming, and gasping. The bulls also have beards running along their throats, and large horns with two and a half twists, which, were they to be straightened, would reach an average length of 120 cm (47 in), with the record being 187.64 cm (73.87 in). They diverge slightly as they slant back from the head. The horns do not begin to grow until the bull is between the ages of 6–12 months. The horns form the first spiral rotation at around 2 years of age, and not reaching the full two and a half rotations until they are 6 years old; occasionally they may even have 3 full turns.
The greater kudu is one of the largest species of antelope, being slightly smaller than the bongo. Bulls weigh 190–270 kg (420–600 lb), with a maximum of 315 kg (694 lb), and stand up to 160 cm (63 in) tall at the shoulder. The ears of the greater kudu are large and round. Cows weigh 120–210 kg (260–460 lb) and stand as little as 100 cm (39 in) tall at the shoulder; they are hornless, without a beard or nose markings. The head-and-body length is 185–245 cm (6.07–8.04 ft), to which the tail may add a further 30–55 cm (12–22 in).
27-5-2019 SOMALISA CAMP, ZIMBABWE - SOUTHERN GREATER KUDU (FEMALE) (Tragelaphus Strepsiceros)
%20(Tragelaphus%20Strepsiceros)%2020.jpg)
The greater kudu (Tragelaphus strepsiceros) is a large woodland antelope, found throughout eastern and southern Africa. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. The greater kudu is one of two species often known as kudu, the other being the lesser kudu, T.imberbis.
The range of the greater kudu extends from the east in Ethiopia, Tanzania, Eritrea and Kenya into the south where they are found in Zambia, Angola, Namibia, Botswana, Zimbabwe and South Africa. Other regions where greater kudu are located are Central African Republic, Chad, Democratic Republic of the Congo, Djibouti, Eswatini, Malawi, Mozambique, Somalia, and Uganda.[8] They have also been introduced in small numbers into New Mexico, but were never released into the wild. Their habitat includes mixed scrub woodlands (the greater kudu is one of the few largest mammals that prefer living in settled areas – in scrub woodland and bush on abandoned fields and degraded pastures, mopane bush and acacia in lowlands, hills and mountains. They will occasionally venture onto plains only if there is a large abundance of bushes, but normally avoid such open areas to avoid becoming an easy target for their predators. Their diet consists of leaves, grass, shoots and occasionally tubers, roots and fruit (they are especially fond of oranges and tangerines).

27-5-2019 SOMALISA CAMP, ZIMBABWE - COMMON IMPALA (FEMALE) (Aepyceros melampus ssp. melampus)
%20(Aepyceros%20melampus%20ssp.%20melampus)%2020.jpg)
The impala or rooibok (Aepyceros melampus, lit. 'black-footed high-horn' in Ancient Greek) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros, and tribe Aepycerotini, it was first described to Europeans by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the grassland-dwelling common impala (sometimes referred to as the Kenyan impala), and the larger and darker black-faced impala, which lives in slightly more arid, scrubland environments. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.

27-5-2019 SOMALISA CAMP, ZIMBABWE - CAPPED WHEATEAR (Oenanthe pileata)
%2020.jpg)
The capped wheatear (Oenanthe pileata) is a small insectivorous passerine bird that is widely distributed over southern Africa. It was formerly classed as a member of the thrush family Turdidae, but is now placed in the Old World flycatcher family, Muscicapidae.
The capped wheatear is 17–18 cm long and weighs 32 g. Its legs and pointed bill are black. This common species is striking and unmistakable in appearance. The adult has a black cap, cheeks and breast band, and white eye stripe and throat. The rest of the underparts are white with buff on the flanks and lower belly. Like other wheatears, it has a distinctive tail pattern with a black feathers on the base and centre of the tail forming an inverted T against the otherwise white rump. The juvenile has a brown cap and cheeks, and the breast band is weak and diffuse. However, the breast band, larger size, and white at the base of the outer tail feathers distinguish it from the migrant northern wheatear, which is rare over most of the capped wheatear's range.
%2021.jpg)
This wheatear is found in open dry sandy and stony habitats and short grassland with a few bushes and termite mounds in Africa, from Kenya and Angola south to the Cape. It is largely non-migratory, but undertakes seasonal movements.
The capped wheatear's song is a loud melodic warble interspersed with slurred chattering, and it has a chik-chik alarm call. It is monogamous and builds a nest of straw, grass, and leaves in a hole in the ground or a termite mound. It may use man-made drainage pipes if available. Typically three or four, sometimes more, eggs are laid. This solitary species feeds on insects, especially ants. Like other wheatears, it perches on mounds and hops over the short grass, or flies low over the ground.
