2-6-2019 LINYANTI CAMP, BOTSWANA - GOLDEN TAILED WOODPECKER (Campethera abingoni)
%2020.jpg)
The golden-tailed woodpecker (Campethera abingoni) is a species of bird in the family Picidae. Its specific name commemorates the 5th Earl of Abingdon. It belongs to a species complex that includes the Knysna woodpecker to the south of its range, and the mostly allopatric Mombasa woodpecker to the northeast, with which it perhaps hybridizes.
It is present in coastal forest, miombo, mopane and acacia woodlands. It shows a preference for riparian woodland, particularly in the dryer parts of southern Africa. It may intensively forage small areas in the lower to middle strata of trees. It establishes fairly large territories of 10 to 15 ha, and can cover some distance between foraging sites.
It obtains most food by probing and gleaning, but also hammers dead or infected wood rather more frequently than other Campethera species. It feeds mostly on arboreal ants and termites, but also takes millipedes, wood-boring larvae and leaf-feeding moth larvae. It occurs alongside the Cardinal woodpecker which to some extent exploits thinner branches.
%2021.jpg)
Very widespread in woodlands or forest south of the equator, and very localized north of it. It is found in Angola, Benin, Botswana, Cameroon, Central African Republic, Chad, Republic of the Congo, Democratic Republic of the Congo, Eswatini, Ivory Coast, Gambia, Ghana, Guinea, Guinea-Bissau, Kenya, Malawi, Mali, Mauritania, Mozambique, Namibia, Rwanda, Senegal, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.
They nest during early summer. Both sexes excavate the nest, usually on the underside of a branch in the lower to middle level of a tree. Two to three glossy white eggs are laid, and the parents take turns to incubate them. The male incubates at night. The incubation period is about 13 days, and the chicks are fed regurgitated food by both parents. Chicks leave the nest after 22 to 25 days. Their nests are parasitized by various species of honeyguide.
2-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN WATTLED LAPWING (Vanellus senegallus)
%2030.jpg)
The African Wattled Lapwing (Vanellus senegallus) is a distinctive, large brownish bird known for its bright yellow facial wattles with red bases, living in moist African grasslands, marshes, and floodplains, feeding on insects, and making loud "peep-peep" calls; they form monogamous pairs, build shallow ground nests, and are non-migratory residents, though they show nomadic movements seasonally, generally considered Least Concern globally despite local habitat threats like afforestation.
%2031.jpg)
Appearance & Identification
Wattles: Large, bright yellow wattles with distinctive fleshy red bases (smaller in juveniles).
Plumage: Brown back, black crown, white forehead, yellow legs and beak, white tail with black tip.
In Flight: Shows black flight feathers, brown coverts, and a white wing bar.
Habitat & Diet
Habitat: Prefers wet areas like marshes, floodplains, lake edges, but also found in dry savanna, cultivated fields, and burnt grasslands.
Diet: Primarily insects (termites, locusts, beetles, caterpillars), worms, and some grass seeds, foraging on the ground.
%2032.jpg)
Behavior & Reproduction
Social: Forms monogamous pairs, often for life, and lives in groups.
Nesting: Builds shallow scrapes on the ground; the male selects the site, and the female chooses where to lay.
Vocalization: Known for loud "peep-peep-peep" calls, especially in flight, used for alarms and territory defense.
Activity: Forages by walking slowly; exhibits nocturnal feeding under full moons.
Status & Range
Distribution: Common across most of sub-Saharan Africa, outside rainforests.
Status: Globally listed as Least Concern (LC) by IUCN, but faces threats from habitat loss and hunting in some areas.
2-6-2019 LINYANTI CAMP, BOTSWANA - NILE MONITOR (Varanus niloticus)
The Nile monitor (Varanus niloticus) is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa, particularly in drier regions, and along the Nile River and its tributaries in East Africa. Additionally, there are modern, invasive populations in North America. The population found in West African forests and savannahs is sometimes recognized as a separate species, the West African Nile monitor (V. stellatus). While it is dwarfed by its larger relatives, such as the Komodo dragon, the Asian water monitor or the crocodile monitor, it is still one of the largest lizards in the world, reaching (and even surpassing) Australia's perentie in size. Other common names include the African small-grain lizard, as well as iguana and various forms derived from it, such as guana, water leguaan or river leguaan (leguan, leguaan, and likkewaan mean monitor lizard in South African English, and can be used interchangeably).
A feral population of Nile monitors (descended from escaped or intentionally-released pets) has become established in several locations in South Florida. In addition to any illegally-released animals, it is speculated that during particularly intense hurricane seasons in Florida, many reptiles potentially escape when their enclosures are damaged or inadvertently unlocked; as Florida has a semi-tropical to tropical climate, many reptiles are housed outdoors, and poorly-secured enclosures may become damaged during bad storms. Along with Nile monitors, Florida is infamous for its feral populations of agamas, Argentine black and white tegus, Burmese pythons, green iguanas, Madagascar giant day geckos, and panther and veiled chameleons, among others. Many of these species are thought to be descendants of hurricane escapees.
2-6-2019 LINYANTI CAMP, BOTSWANA - AFRICAN LION (Panthera leo)
The lion (Panthera leo) is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex and keystone predator.
Among felids, the lion is second only to the tiger in size. The size and weight of adult lions vary across its range and habitats.
The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.
One of the most widely recognised animal symbols in human culture, the lion has been extensively depicted in sculptures and paintings, on national flags, and in literature and films. Lions have been kept in menageries since the time of the Roman Empire and have been a key species sought for exhibition in zoological gardens across the world since the late 18th century. Cultural depictions of lions have occurred worldwide, particularly has a symbol of power and royalty.
African lions live in scattered populations across sub-Saharan Africa. The lion prefers grassy plains and savannahs, scrub bordering rivers, and open woodlands with bushes. It rarely enters closed forests. On Mount Elgon, the lion has been recorded up to an elevation of 3,600 m (11,800 ft) and close to the snow line on Mount Kenya. Savannahs with an annual rainfall of 300 to 1,500 mm (12 to 59 in) make up the majority of lion habitat in Africa, estimated at 3,390,821 km2 (1,309,203 sq mi) at most, but remnant populations are also present in tropical moist forests in West Africa and montane forests in East Africa. The Asiatic lion now survives only in and around Gir National Park in Gujarat, western India. Its habitat is a mixture of dry savannah forest and very dry, deciduous scrub forest.
12-6-2019 MONTE CORONA, VALENCIA - SHORT HORNED GRASSHOPPER (Genus Calliptamus)
%2020.jpg)
Physical Appearance: These grasshoppers are typically medium-sized with a basic coloration that varies from gray to brownish-reddish, often marked with small dark spots. A key identification feature is the reddish or pinkish coloration on the hind wings and the inner side of the hind femora, which is especially visible during flight.
Sexual Dimorphism: The genus exhibits significant sexual dimorphism; females are considerably larger than males. Males typically grow up to 14–26 mm, while females can reach 21–40 mm in length.
Habitat and Distribution: Species of Calliptamus thrive in arid, sunny areas and fixed dunes. Their range extends across the northern Palearctic realm to Japan, the Mediterranean Basin, and Africa.
Diet and Pest Status: They are polyphagous, meaning they feed on a variety of plants, with a strong preference for legumes, but they also infest cereals and grapevines. Species like the Italian locust (C. italicus) can exhibit gregarious behavior and form swarms (locust plagues) under certain conditions, causing substantial economic losses to crops.

1-6-2019 LINYANTI CAMP, BOTSWANA - CHAPMAN'S ZEBRA (Equus quagga ssp. chapmani)
Chapman's zebra (Equus quagga chapmani), named after explorer James Chapman, is a subspecies of the plains zebra from southern Africa.
Chapman's zebra are native to savannas and similar habitats of north-east South Africa, north to Zimbabwe, west into Botswana, the Caprivi Strip in Namibia, and southern Angola. Like the other subspecies of plains zebra, it is a herbivore that exists largely on a diet of grasses, and undertakes a migration during the wet season to find fresh sources of food and to avoid lions, which are their primary predator. Chapman's zebras are distinguished from other subspecies by subtle variations in their stripes. When compared to other equids in the region Chapman's zebras are relatively abundant in number, however its population is now in decline largely because of human factors such as poaching and farming. Studies and breeding programs have been undertaken with the hope of arresting this decline, with a focus on ensuring zebras bred in captivity are equipped for life in the wild, and that non-domesticated populations are able to freely migrate. A problem faced by some of these programs is that captive Chapman's zebra populations experience higher incidence of diagnosed diseases than non-domesticated populations because they live longer, and so are less likely to die in the wild from predation or a lack of food or water.
Chapman's zebras are single-hoofed mammals that are a part of the odd-toed ungulate order. They differ from other zebras in that their stripes continue past their knees, and that they also have somewhat brown stripes in addition to the black and white stripes that are typically associated with zebras. The pastern is also not completely black on the lower half. Each zebra has its own unique stripe pattern that also includes shadow stripes. When foals are born, they have brown stripes, and in some cases, adults do not develop the black colouration on their hides and keep their brown stripes.
In the wild Chapman's zebra live on average to 25 years of age, however that can live to be up to 38 years of age in captivity. Males usually weigh 270–360 kg (600–800 lb) and stand at 120–130 cm (48–52 in) tall. Females weigh about 230–320 kg (500–700 lb) and stand as tall as the males. Foals weigh 25-50 kg (55-88 lb) at birth. Adult zebras can run at up to 56 kilometres per hour (35 miles per hour) and have strong eyesight and hearing which are essential evolutionary defence mechanisms.
1-6-2019 LINYANTI CAMP, BOTSWANA - HAMERKOP (Scopus umbretta)
%2020.jpg)
The Hamerkop (Scopus umbretta), a medium-sized wading bird, is the sole representative of its genus and family. Its distinctive hammer-shaped head, complete with a long bill and a rear crest, has inspired its name from the Afrikaans term for "hammerhead." Exhibiting a uniform brown plumage, this bird is a familiar sight across Africa, Madagascar, and parts of Arabia.
Adult Hamerkops are characterized by their brown plumage with a subtle purple sheen on the back. The tail features faint barring of a darker brown. Both sexes appear similar, and juveniles resemble the adults. The bill, long and slightly hooked, is particularly compressed and thin, especially towards the lower mandible. Initially brown in young birds, the bill darkens to black upon fledging.
Hamerkops are found in a plethora of wetland habitats, ranging from estuaries, lakesides, and fish ponds to riverbanks and rocky coasts. They have also adapted to human-altered environments, often seen in villages and agricultural areas.
This species is widespread across sub-Saharan Africa, Madagascar, and coastal southwestern Arabia. It is generally sedentary, with some local movements observed.
%2021.jpg)
Active predominantly during daylight, Hamerkops may rest during the midday heat and exhibit some crepuscular activity. They are known for their peculiar jerky walk, with their head and neck moving in sync with each step.
When solitary, the Hamerkop is relatively quiet, save for a shrill flight-call. In contrast, when in groups, it becomes more vocal, producing a variety of cackles and nasal rattles. The "yip-purr" call is a notable social vocalization, often accompanied by wing flapping.
Hamerkops are renowned for their massive nests, which are sturdy enough to support a human's weight. These nests, built by both parents, feature an internal chamber for egg-laying and are often constructed in tree forks or on human structures. Both parents share incubation duties and chick rearing.
A generalist feeder, the Hamerkop's diet includes fish, amphibians, shrimps, insects, and occasionally rodents. It hunts in shallow waters, using both sight and touch, and is known to be adaptable in its feeding strategies.
The Hamerkop is classified as Least Concern by the IUCN, with a stable population trend and widespread local abundance in its range.
1-6-2019 LINYANTI CAMP, BOTSWANA - BLACKSMITH LAPWING (Vanellus armatus)
The Blacksmith Lapwing (or Plover) is a bold, black, white, and gray African bird named for its loud, metallic "tink-tink-tink" call, like a hammer on an anvil, used to defend its wetland territory and nest. These monogamous, territorial birds use a sharp spur on their wing for aggressive defense, dive-bombing threats, even elephants, and feed on invertebrates from mudflats and grasslands. They build simple ground nests near water and are common, widespread, and not currently threatened.
Key Facts:
Name Origin: Its distinctive loud, metallic call sounds like a blacksmith's hammer, hence the name.
Appearance: Striking black, white, and gray patterns with bold patches, red eyes, and a sharp spur on its wrist (carpal spur) used for defense, notes Wikipedia.

9-6-2019 KWHAI CAMP, BOTSWANA - SOUTHERN WHITE CROWNED SHRIKE (Eurocephalus angustimens)
%2020.jpg)
The Southern White-crowned Shrike (Eurocephalus anguitimens) is a social, insect-eating bird of African savannas, known for its striking white crown and black mask, living in family groups that cooperatively raise young in neat cup nests, and hunting insects and small prey from conspicuous perches, often impaling them like other shrikes. They are monogamous, found in countries like Botswana, Namibia, and South Africa, and have a distinctive, shrill call.
%2021.jpg)
Key Facts:
Appearance: Large-headed, bulky bird with a distinct white crown, black mask, ashy-brown back, and off-white underparts.
Habitat: Arid savannas, dry woodlands, and riverine forests in Southern Africa (Angola, Botswana, Namibia, South Africa, Zimbabwe).
Social Behavior: Lives in family groups (pairs plus 1-6 helpers) that cooperate in nesting and chick-rearing.
Diet: Primarily insects (caterpillars, beetles, ants) but also small vertebrates, hawking them from perches or hunting on the ground.
%2022.jpg)
Hunting: Perches high to watch for prey, often impaling surplus food on thorns or barbed wire.
Nesting: Builds a thick, cup-shaped nest of grass and spiderwebs in tree forks, with helpers assisting.
Reproduction: Lays 2-5 eggs, incubated for about 20 days; chicks fledge in around 3 weeks.
Vocalization: Known for a distinctive, shrill, plover-like call, "kleeew-keeuw".
Name: Called Kremetartlaksman in Afrikaans; Eurocephalus means "broad-headed" in Greek.

6-6-2019 MOREMI CAMP, BOTSWANA - COMMON OSTRICH (Struthio camelus)
The common ostrich (Struthio camelus), the planet's largest bird, is a flightless avian native to Africa. It is a member of the ratite family, which includes other flightless birds like emus and kiwis. The ostrich is known for its impressive size, long neck, and powerful legs, which allow it to reach speeds of up to 70 km/h (43 mph) in short bursts. Males are typically larger than females and boast striking black and white plumage, while females are predominantly brown.
Adult males are characterized by their black feathers with white wings and tail. Females and young males are more subdued in color, displaying grayish-brown feathers. The ostrich's head and neck are sparsely feathered, revealing their skin, which can vary from gray to pinkish tones. They have large eyes, adapted for spotting predators at great distances, and long, muscular legs with two-toed feet.
Ostriches are adapted to a variety of habitats, from savannas to deserts across Africa. They are capable of surviving in extreme conditions, from the scorching heat to areas with scarce water.
Once found throughout Africa and parts of Asia, the common ostrich's range has been reduced due to hunting and habitat loss. Today, they are primarily found in sub-Saharan Africa, with some populations in North Africa and the Sahel region.
Ostriches are nomadic, often traveling in small groups that can range from 5 to 50 individuals. They are known for their running ability, using their speed as a primary defense mechanism. When threatened, they may lie flat against the ground to avoid detection or deliver powerful kicks to defend themselves.
The common ostrich produces distinct vocalizations, including booming calls by males during the mating season, which can be heard over long distances.
Ostriches have complex mating behaviors, with males courting females through elaborate dances and displays. They are known for their communal nesting practices, where several females may lay their eggs in a single nest for incubation.
The Somali ostrich (Struthio molybdophanes), once considered a subspecies, is now recognized as a separate species. It can be distinguished by its blue-gray neck and legs.
Ostriches are omnivores, primarily consuming plant matter such as seeds, shrubs, and fruits, but they will also eat invertebrates and small reptiles. They lack teeth and ingest pebbles to aid in grinding food in their gizzard.
The common ostrich is classified as Least Concern by the IUCN, though certain subspecies, like the North African ostrich, are under greater threat and are listed in CITES Appendix I, which restricts international trade.
6-6-2019 KHWAI CAMP, BOTSWANA - WATTLED CRANE (Grus carunculatus)
The wattled crane (Grus carunculata) is a large, threatened species of crane found in wetlands and grasslands of eastern and southern Africa, ranging from Ethiopia to South Africa. Some authorities consider it the sole member of the genus Bugeranus.
The wattled crane occurs in eleven countries in eastern and southern Africa, including an isolated population in the Ethiopia Highlands. More than half of the world's wattled cranes occur in Zambia, but the single largest concentration occurs in the Okavango Delta of Botswana.
The wattled crane has been spotted in Uganda for the first time in 2011, seen in the Kibimba Rice region in the eastern side of the country. This sighting brings the total number of bird species in Uganda to 1040.
In April 2018, a new population of Wattled Cranes was discovered in Angola.
Wattled cranes inhabit fairly inaccessible wetlands under most conditions. It requires shallow marsh-like habitats with a good deal of sedge-based vegetation. All cranes are omnivorous. The principal food of the wattled crane is mainly aquatic eating the tubers and rhizomes of submerged sedges and water lilies. It is one of the more herbivorous of extant cranes. The other primary portion of the diet consists of aquatic insects. They will supplement the diet with snails, amphibians and snakes when the opportunity arises. Roughly 90% of foraging done by this species occurs in shallow waters. They typically forage by digging vigorously with their bill into the muddy soil. On occasion, it will eat grain and grass seed as well, but does so much less often than the other three African crane species.
There does seem to be some seasonal movements in this crane species, but they are not well-known. Movements seem to be dictated by local water conditions rather than by seasonal temperature variations. During local floods, the number of wattled cranes can increase from almost none to as much as 3,000 individuals.
These movements, in pursuit of ideal feeding conditions, seem more opportunistic movement rather than a fixed migration pattern. On the other hand, there has been observed a migration movement from the high to the low plateaus in Mozambique for the species.

5-6-2019 MOREMI CAMP, BOTSWANA - MARABOU STORK (Leptoptilos crumenifer)
%2020.jpg)
The Marabou Stork, Leptoptilos crumenifer, is a formidable presence in the avian world, with its massive stature and striking appearance. It stands tall at approximately 152 centimeters and can weigh up to 9 kilograms. Its wingspan is a sight to behold, stretching up to 3.7 meters, rivaling even the Andean condor in breadth. The marabou is adorned with a black back, contrasting white underparts, and a distinctive bare head and neck. Its bill is robust, and it sports a pink gular sac at its throat, a neck ruff, and white legs. Both sexes appear similar, though the female is typically smaller, and juveniles are browner with a less pronounced bill.
To identify the Marabou Stork, look for its large size, bare head, and neck, along with its black back and white underparts. The bird's enormous bill and pink throat sac are also key characteristics. When in flight, note that unlike most storks, the Marabou Stork flies with its neck retracted, resembling a heron.
The Marabou Stork is native to sub-Saharan Africa, where it can be found in a variety of habitats, both wet and arid. It often resides near human habitation, particularly around landfill sites.
4-6-2019 LINYANTI CAMP, BOTSWANA - TAWNY EAGLE (Aquila rapax)
The tawny eagle (Aquila rapax) is a large bird of prey. Like all eagles, it belongs to the family Accipitridae. Its heavily feathered legs mark it as a member of the subfamily Aquilinae, also known as booted eagles. Tawny eagles have an extensive but discontinuous breeding range that constitutes much of the African continent as well as the Indian subcontinent, with rare residency in the southern Middle East. Throughout its range, it favours open dry habitats such as semideserts, deserts steppes, or savanna plains. Despite its preference for arid areas, the species seldom occurs in areas where trees are entirely absent. It is a resident breeder which lays one to three eggs in a stick nest most commonly in the crown of a tree.
The tawny eagle is perhaps the most highly opportunistic of all Aquilinae, and often scavenges on carrion or engages in kleptoparasitism towards other carnivorous animals but is also a bold and active predator, often of relatively large and diverse prey. It is estimated that tawny eagles can reach the age of 16 years old. Nonetheless, precipitous declines have been detected throughout the tawny eagle's range. Numerous factors, particularly loss of nesting habitat due to logging and global warming, as well as persecution (largely via poisoning) and other anthropogenic mortality (largely through contact with various manmade objects) are driving the once numerous tawny eagle perhaps to the brink of extinction.
The tawny eagle is considered to appear "inelegant, scruffy-looking" but has a fairly characteristic aquiline silhouette. The species has a fairly long neck and long deep bill with a gape line level with the eye, moderately long wings with fairly pronounced "fingers" and a slightly rounded to almost square-ended and shortish tail, which can be more reminiscent of the tail of a vulture than that of other eagles. The feathering on the legs is extensive and can appear almost baggy-looking. The bill and head are strong and bold, the body well-proportioned and feet are powerful while the countenance is quite fierce-looking. While perching, the tawny eagle tends to sit rather upright, often on stumps, posts, low trees or treetops for long periods of the day or may descend to the ground to walk somewhat unsteadily with a more horizontal posture. The wingtips when perched are roughly even with the tip of the tail. Adults have variably colored eyes, ranging from yellow to pale brown to yellow brown, while those of juveniles are dark brown. Both the cere and feet are yellow at all ages.
The tawny eagle is polymorphic with considerable individual variation in plumage, resulting in occasional disparities in plumages that can engender confusion in some. In adulthood, they can vary in coloration from all dark grey-brown to an occasionally streaky (or more plain) foxy-rufous to buffish-yellow. Most adults are usually a general grey-brown or rufous-tawny color, with occasional pale spotting visible at close quarters on the nape and belly, coverts uniformly toned as the body. The nape is consistently dark and uniform despite the feathers often being tipped paler with other feathers in adults, lacking the contrasting paler feathers often seen in other Aquila. Females, in addition to being slightly larger, may tend to be slightly darker and more streaked than the males. The most blackish-brown individuals tend to occur in India. Adults often show relatively little varying colors apart from their somewhat blacker wing and tail feathers, though when freshly molted great wing coverts and secondaries may show small pale tips which may form pale lines along closed wing has tawny upper parts and blackish flight feathers and tail.
Tawny eagles have an extremely extensive natural distribution. The African population can be found in three, fairly discrete populations. One of these is found in North Africa in south-central Morocco, possibly northern Algeria, southwestern Mauritania, Senegambia, southern Mali, central and southern Niger eastward through southern Chad, northern and central Sudan to most of Ethiopia and Somalia (but for the northeast and central-east). The north African population is scarce. In Morocco, they are heavily depleted with a few populations left in some regions such as Tarfaya, Tan-Tan and Souss-Massa. They are likely extirpated from Tunisia, where they were once frequent. In West Africa, some tawny eagles occur in Gambia, Togo, Nigeria and (though possibly not breeding) in Ivory Coast and Ghana. In east Africa and central Africa, the tawny eagle is found in central and eastern Democratic Republic of the Congo and throughout the drier portions of Uganda and in the entire nations of Kenya, Tanzania, Zambia (quite often residing in the Luangwa valley and the Chambeshi drainage), Malawi and Mozambique. In east Africa, it is considered perhaps the most widely distributed and regularly sighted brown eagle. In southern Africa, the tawny eagle is found throughout Zimbabwe (now often rare apart from Matabeleland and Chipinga Uplands), Botswana (still regular in Okavango Delta) and some areas of Namibia, southern and western Angola (Cuando Cubango, Cunene, Huíla Namibe, to Malanje), Eswatini, Lesotho and northern and central parts of South Africa, i.e. mainly north of the Orange River but sometimes down to the Cape Province.
