6-6-2019 KHWAI CAMP, BOTSWANA - BLACKSMITH LAPWING (Vanellus armatus)
The Blacksmith Lapwing, known scientifically as Vanellus armatus, is a striking bird with a bold pattern of black, grey, and white, which may serve as a warning to predators. Its red eyes are a distinctive feature, shared with only four other lapwing species across the globe. Adorning the wrist joint is a carpal spur, a sharp black protrusion used in defense of their young, with aggressive aerial dives often aimed at the heads of intruders.
When identifying the Blacksmith Lapwing, look for its red eyes and the contrasting pied plumage. The bill and portions of the legs are black, with the legs sometimes showing a white-grey mottling. The sexes appear similar, though females tend to be slightly larger and heavier.
This lapwing species is commonly found in association with wetlands of varying sizes, from expansive marshes to the smallest damp areas caused by spilling water troughs. In South Africa, they are particularly abundant in mesic grassland regions.
The Blacksmith Lapwing is a common sight from Kenya through central Tanzania to southern and southwestern Africa. They have expanded their range in the 20th century, notably establishing a presence in the western Cape region of South Africa since the 1930s.
Partially migratory, the Blacksmith Lapwing does not engage in large-scale, regular migrations. They are known to be aggressive during the breeding season, particularly towards other lapwings or African jacanas entering their territory.
Breeding occurs in spring, with nests being shallow depressions on bare ground or short grass near water. The nests are typically spaced at least 400 meters apart. After breeding, the young gradually separate from their parents and do not return to their natal areas.
The diet of the Blacksmith Lapwing consists of aquatic and terrestrial invertebrates, which they forage for in their wetland habitats.
The IUCN Red List classifies the Blacksmith Lapwing as Least Concern, indicating that the species does not currently face a significant risk of extinction.

6-6-2019 KHWAI CAMP, BOTSWANA - NILE MONITOR (Varanus niloticus)
%2014.jpg)
The Nile monitor (Varanus niloticus) is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa and along the Nile, with invasive populations in North America. The population in West African forests and savannahs is sometimes recognized as a separate species, the West African Nile monitor (V. stellatus). It is one of the largest lizards in the world reaching and even surpassing the perentie by 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 the lizards, descended from escaped or intentionally released pets, has become established in several locations in Florida.

Nile monitors are native to Sub-Saharan Africa and along the Nile. They are not found in any of the desert regions of Africa (notably Sahara, Kalahari and much of the Horn of Africa), however, as they thrive around rivers. Nile monitors were reported to live in and around the Jordan River, Dead Sea, and wadis of the Judaean Desert in Israel until the late 19th century, though they are now extinct in the region.

Nile monitors are often found in the pet trade despite their highly aggressive demeanor and resistance to taming. Juvenile monitors will tail whip as a defensive measure, and as adults they are capable of inflicting moderate to serious wounds from biting and scratching. Nile monitors require a large cage as juveniles quickly grow when fed a varied diet, and large adults often require custom-built quarters.
"There are few lizards less suited to life in captivity than the Nile monitor. Buffrenil (1992) considered that, when fighting for its life, a Nile monitor was a more dangerous adversary than a crocodile of a similar size. Their care presents particular problems on account of the lizards' enormous size and lively dispositions. Very few of the people who buy brightly-coloured baby Nile monitors can be aware that, within a couple of years, their purchase will have turned into an enormous, ferocious carnivore, quite capable of breaking the family cat's neck with a single snap and swallowing it whole."

6-6-2019 KHWAI CAMP, BOTSWANA - WATER THICK NEE (Barhinus Vermiculatus)
%2014.jpg)
The water thick-knee or water dikkop (Burhinus vermiculatus) is a species of bird in the thick-knee family Burhinidae. The species is found across sub-Saharan Africa, usually close to water.
%2015.jpg)
The water thick-knee has a widespread distribution in sub-Saharan Africa, being found in Angola, Botswana, Burkina Faso, Burundi, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Eswatini, Ivory Coast, Ethiopia, Gabon, Ghana, Kenya, Liberia, Malawi, Mozambique, Namibia, Niger, Nigeria, Rwanda, Senegal, Somalia, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.
Across its range it is found on the edges of lakes, estuaries and rivers, as well as mangroves and also some sheltered beaches. It also needs bushes or nearby woodlands for shelter. It is found from sea-level to 1,800 m (5,900 ft).
%2016.jpg)
The water thick-knee is a terrestrial feeder that forages at night. Although it is typically associated with water it can be found foraging up to 1 km (0.62 mi) from water. It feeds on insects, crustaceans and mollusks.
The water thick-knee generally breeds in the dry season or early rainy season. It is a monogamous breeder with both parents guarding the nest and brooding the eggs. The nest is a simple scrape in sandy or stony ground, usually close to water. The clutch size is two sandy-yellow eggs. Both sexes incubate the eggs for 22-25 days, and both are responsible for feeding the young. Unique among birds, thick-knee pairs frequently nest adjacent to and sometimes directly on top of Nile crocodile nests. The two species share a form of symbiotic mutualism with the more energetic and vocal thick-knee functioning as loud sentries for the nests as the more powerful crocodile provides protection. Should a nest raider approach, the thick-knee pair will spread their wings in a threat display and harass and peck at the intruders to drive it off. If the pair not be successful, the mother crocodile will be drawn in by their continued calls and arrive.

6-6-2019 KHWAI CAMP, BOTSWANA - AFRICAN SAVANNA ELEPHANT (JUVENILE) (Loxodonta Africana)
%2010.jpg)
The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.
%2011.jpg)
The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth, a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.
Since 2021, the African bush elephant has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement. Poaching of the elephant has dated back to the 1970s and 80s, which were considered the largest killings in history. In human culture, elephants have been extensively featured in literature, folklore and media, and are most valued for their large tusks in many places.

6-6-2019 KHWAI CAMP, BOTSWANA - NORTHERN HADADA IBIS (Bostrychia hagedash ssp. brevirostris)
Bostrychia hagedash brevirostris - Senegal to Kenya and south to Zambezi Valley. The Northern hadada ibis (Bostrychia hagedash ssp. brevirostris) or hadeda (/ˈhɑːdiːdɑː/) is an ibis native to Sub-Saharan Africa. It is named for its loud three to four note calls uttered in flight especially in the mornings and evenings when they fly out or return to their roost trees. Although not as dependent on water as some ibises, they are found near wetlands and often live in close proximity to humans, foraging in cultivated land and gardens. A medium-sized ibis with stout legs and a typical down-curved bill, the wing coverts are iridescent with a green or purple sheen. They are non-migratory but are known to make nomadic movements in response to rain particularly during droughts. Their ranges in southern Africa have increased with an increase in tree cover and irrigation in human-altered habitats.

6-6-2019 KHWAI CAMP, BOTSWANA - BLACK WINGED STILT (Himantopus himantopus)
%2020.jpg)
The Black-winged Stilt, Himantopus himantopus, is a slender wader known for its strikingly long, pink legs and contrasting black-and-white plumage. This elegant bird is a member of the avocet and stilt family, Recurvirostridae.
Adult Black-winged Stilts measure 33–36 cm in length. They possess a long, thin black bill and display a distinctive black and white coloration. The head and neck are predominantly white, with variable black markings depending on the sex and subspecies. Males typically have a glossy or greenish sheen on their black backs, while females exhibit a more brownish tinge. During flight, their long legs trail behind, and their wingbeats are steady.
These birds favor marshes, shallow lakes, and ponds as their breeding grounds. They are also known to inhabit coastal areas during migration and in the winter months.
The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

6-6-2019 MOREMI CAMP, BOTSWANA - DOUBLE BANDED SANDGROUSE (MALE) (Pterocles bicinctus)
%201.jpg)
The double-banded sandgrouse (Pterocles bicinctus ) is a species of ground-living bird in the family Pteroclidae. It is found in arid parts of southern Africa.
A moderate sized bird with a plump body, the double-banded sandgrouse has a small pigeon-like head and long wings and tail. The general colour of the plumage is light brown with darker mottling and rows of whitish specks. The male is distinguished by having a conspicuous black and white band on its forehead and a chestnut throat area delineated by another black and white band. Both sexes have an area of bare yellow skin surrounding their eye and the male has an orange beak. The female is smaller and duller in colour. The juvenile resembles the female.
%202.jpg)
The double-banded sandgrouse is found in Angola, Botswana, Malawi, Mozambique, Namibia, South Africa, Zambia and Zimbabwe. It has a preference for short trampled grass beside roads and tracks, gravel patches, tussocky grassland and recently burned areas of scrub with green shoots starting to develop. It is also seen in areas of scanty vegetation beneath scattered Terminalia sericea and Burkea africana trees and in scrubby mopane woodland. It is less common than Burchell's sandgrouse (Pterocles burchelli ) and Namaqua sandgrouse (Pterocles namaqua ), both of which have an overlapping distribution in southern Africa.
