18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - SOUTHERN RED BILLED HORNBILL (Tockus rufirostris)

The Southern red-billed hornbill, Tockus rufirostris, is a distinguished member of the Bucerotidae family, gracing the savannas and drier bushlands of southern Africa with its presence. This bird is characterized by its striking red bill and the streaks of blackish plumage that extend from its ear coverts down the side of its neck.

Upon observing this species, one will note the sexual dimorphism where males are generally larger with slightly longer bills. The male's lower mandible may exhibit varying degrees of black pigmentation. Both sexes boast a yellow iris surrounded by pale orbital skin, ranging from pink to greyish hues. The throat is a pristine white, and the wing coverts are adorned with conspicuous spots.

The Southern red-billed hornbill is a native inhabitant of the savannas and dryer bushlands, thriving in these open environments where it can forage and nest.

This hornbill's range extends from Malawi and Zambia to southern Angola, northeastern Namibia, Botswana, Zimbabwe, eastern Eswatini, and northern South Africa, including Transvaal and northern KZN province. It is also found in the upper Zambezi valley of Mozambique, though it is mostly absent from the eastern lowlands.

A notable behavior of the Southern red-billed hornbill is its unique call, an accelerating series of notes that culminates in a crescendo of double notes. Unlike its congeners, this species does not engage in wing-raising displays.

The vocal repertoire of this hornbill includes a distinctive call that starts with a series of "kuk kuk kuk" notes and ends with a flourish of double notes, "kuk-we kuk-we."

The Southern red-billed hornbill can be confused with other red-billed hornbills, but it can be distinguished by its unique combination of yellow iris, pale orbital skin, and the pattern of blackish streaking on the neck.

The conservation status of the Southern red-billed hornbill is not explicitly mentioned, but given its wide distribution, it may not currently be of significant conservation concern. However, like all wildlife, it would benefit from ongoing habitat protection and monitoring.

17-4-2018 CHOBE NATIONAL PARK, BOTSWANA - PUKU (Kobus vardonii)

The puku (Kobus vardonii) is a medium-sized antelope found in wet grasslands in southern Democratic Republic of Congo, Namibia, Tanzania, Zambia and more concentrated in the Okavango Delta in Botswana. Nearly one-third of all puku are found in protected areas, zoos, and national parks due to their diminishing habitat.

Puku stand about 80 cm (31 in) at the shoulder and weigh from 70 to 80 kg (150 to 180 lb). The puku is sandy brown in colour, with the underbelly a slightly lighter brown. The coat is rougher than that of the similar-sized southern reedbuck, lechwe or impala, or the smaller oribi. Males have horns which are ridge-structured, 50 cm (20 in) long, and lyre-shaped.

There are two subspecies, the Senga Puku (Kobus vardonii senganus) and the southern puku (Kobus vardonii vardonii).

A gregarious antelope occurring in small herds. The social system is centralised on adult males maintaining and defending territories which accord them breading opportunities amongst wondering female herds.

The Puku is predominantly a grazing specie.

Mating and births occurs throughout the year with a peak during the summer rainy season.

They favour a riverine or floodplains habitat. They utilise grasslands adjacent to rivers or swamps.

Puku has a central African distribution and only marginally occurs in Botswana.

7-4-2018 CHOBE NATIONAL PARK, BOTSWANA - SOUTHERN SABLE ANTELOPE (Hippotragus niger ssp niger)

The sable antelope (Hippotragus niger) is a large antelope which inhabits wooded savanna in East and Southern Africa, from the south of Kenya to South Africa, with a separated population in Angola.

The sable antelope shares the genus Hippotragus with the extinct bluebuck (H. leucophaeus) and the roan antelope (H. equinus), and is a member of the family Bovidae.

The sable antelope is sexually dimorphic, with the male heavier and about one-fifth taller than the female. The head-and-body length is typically between 190 and 255 cm (75 and 100 in). Males reach about 117–140 cm (46–55 in) at the shoulder, while females are slightly shorter. Males typically weigh 235 kg (518 lb) and females 220 kg (490 lb). The tail is 40–75 cm (16–30 in) long, with a tuft at the end.

The sable antelope has a compact and robust build, characterized by a thick neck and tough skin. It has a well-developed and often upright mane on its neck, as well as a short mane on the throat. Its general colouration is rich chestnut to black. Females and juveniles are chestnut to dark brown, while males begin darkening and turn black after three years. However, in southern populations, females have a brown to black coat. Calves less than two months old are a light tan and show faint markings. The underparts, cheek, and chin are all white, creating a great contrast with the dark back and flanks. Long, white hairs are present below the eyes, and a wide, black stripe runs over the nose.

18-4-2018 CHOBE NAT PARK, BOTSWANA - BLACK HEADED HERON (Ardea melanocephala)

The black-headed heron, Ardea melanocephala, is a stately wading bird from the heron family Ardeidae. It stands at an impressive 85 cm in height, with a wingspan stretching to 150 cm. Its plumage is predominantly grey, with a darker shade above and a paler grey below. The bird is named for its striking black head, which contrasts with its grey body. A powerful dusky bill completes its commanding appearance.

When identifying the black-headed heron, look for its large size, nearly matching that of the grey heron. Its black head and neck, along with the grey body, are key distinguishing features. In flight, observe the slow wingbeats and the retracted neck, a common trait among herons. The white underwing coverts are particularly noticeable when the bird is airborne.

This heron is commonly found in a variety of wetland habitats throughout sub-Saharan Africa and Madagascar. It is comfortable in both shallow water and dry grasslands.

The black-headed heron is widespread across much of sub-Saharan Africa and Madagascar. It is mainly a resident species, though some individuals from West Africa may migrate northward during the rainy season.

The black-headed heron exhibits typical heron behavior, often seen feeding in shallow waters or stalking prey in grasslands. It is known to stand motionless, waiting for prey, or to slowly stalk its victim with stealth and precision.

The vocalizations of the black-headed heron include a distinctive loud croaking, often heard during dusk at heronries.

Breeding typically occurs in the wet season. The black-headed heron nests in colonies, which can be found in trees, reedbeds, or even on cliffs. It constructs a bulky stick nest and lays a clutch of 2 to 4 eggs.

The grey heron is the species most similar in appearance to the black-headed heron, but it can be differentiated by its size and coloration, particularly the grey heron's lack of a black head.

A versatile predator, the black-headed heron feeds on a diet that includes fish, frogs, large insects, small mammals, and birds. It employs both passive and active hunting strategies, either spearing its prey with its sharp bill or stalking it on land.

The IUCN Red List classifies the black-headed heron as Least Concern, indicating that the species does not currently face a significant threat of extinction.

18-4-2018 CHOBE NAT PARK, BOTSWANA - RED NECKED FALCON (Falco chicquera)

The Red-necked Falcon, a medium-sized raptor, boasts a striking rufous crown and nape, contrasting with its bluish-grey wings and upper body. The bird's tail features narrow bars and a distinctive broad subterminal black band tipped with white. The legs, ceres, and eyering are a vibrant yellow, while the bill's tip is black and the base a greenish yellow. The species exhibits sexual dimorphism, with females being larger than males.

Adults have a wingspan of approximately 85 cm and measure 30–36 cm in length. The wingtip does not extend to the tail tip when at rest. The second and third primaries are nearly equal in length, with the first being significantly shorter. The species' call is a piercing ki-ki-ki-ki, and juveniles can be identified by their buff underparts and less pronounced barring.

In Africa, the Red-necked Falcon inhabits semi-desert, savannah, and other dry open areas with sparse trees, including riverine forests. It is often seen perched atop Borassus palms, which are also used for breeding. In India, the species favors open habitats and avoids dense forests and high elevations.

The Red-necked Falcon has two distinct populations: one in India and another in sub-Saharan Africa. The Indian subspecies was historically found as far west as southeastern Iran, while the African subspecies is sometimes considered a separate species due to its unique geographic range and pattern.

These falcons hunt primarily at dawn and dusk, often in pairs. They employ a unique hunting strategy where one bird flushes out prey by flying low, while the other captures the startled prey from above. They are known to feed on a variety of birds, bats, and squirrels.

The Red-necked Falcon's vocalization is characterized by a shrill ki-ki-ki-ki.

Breeding seasons vary by region, with January to March in India and beginning in August in Zambia. Courtship feeding is a unique behavior where the female feeds the male. They typically reuse old nests of corvids or build their own in tree forks or palm crowns. The female incubates the eggs, which hatch after about 32 to 34 days.

The Red-necked Falcon preys on open-area birds, bats, and occasionally small mammals and large insects. They have been observed caching prey for later consumption.

The Red-necked Falcon is currently listed as Near Threatened on the IUCN Red List, indicating that it faces threats that could lead to its vulnerability in the near future.

Historically, the Red-necked Falcon was a favored bird among Indian falconers, particularly for hunting the Indian roller due to the engaging aerial chases it would provoke.

18-4-2018 CHOBE NAT PARK, 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.

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.

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. 

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.

17-4-2018 CHOBE RIVER, BOTSWANA - BLACK HERON (Egretta ardesiaca)

The black heron nests at the onset of the rainy season, either alone or in mixed-species colonies that can number in the hundreds. Its nests are constructed from twigs and are situated over water in trees, bushes, or reed beds. The eggs are described as dark blue, and a typical clutch comprises two to four eggs.

The black heron is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline or habitat loss at a global scale.

The black heron, also known as the black egret, is a medium-sized bird, cloaked in an alluring black plumage that is complemented by a similarly hued bill and contrasting yellow feet.

18-4-2018 CHOBE NAT PARK, BOTSWANA - MARTIAL EAGLE (Polemaetus bellicosus)

The Martial Eagle (Polemaetus bellicosus), a formidable raptor, reigns over the sub-Saharan skies. This solitary species, the sole member of its genus, is distinguished by its impressive size and power. With feathered tarsi characteristic of the booted eagle subfamily, it is one of the largest of its kind. The Martial Eagle is an apex predator, soaring high to stoop upon a diverse array of prey, from mammals to reptiles.

Adult Martial Eagles exhibit a dark brown plumage on their upperparts, head, and upper chest, with occasional lighter feather edges. Their underparts are white, marked with sparse blackish-brown spots. In flight, their long broad wings and short tail give them a distinctive silhouette. Juveniles are paler with a greyish mottled appearance and take up to seven years to acquire their adult plumage.

The Martial Eagle favors wooded belts within open savanna landscapes, avoiding dense forests and arid deserts. It is often found perched in an upright position in large trees, surveying its territory.

This eagle's range spans across sub-Saharan Africa, with higher densities in southern and parts of east Africa. It is more sporadic in west Africa, with notable populations in protected areas such as South Africa's Kruger National Park.

Martial Eagles spend a significant portion of their day aloft, soaring at great heights. They are solitary outside of the breeding season and exhibit a preference for less disturbed areas, likely due to the abundance of prey and aversion to human activity.

The Martial Eagle is not a frequent vocalizer, but it does emit a low mellow whistle as a contact call and a louder, trilling call during territorial displays.

Breeding occurs at various times across their range, with nests built high in large trees. They lay usually one egg, with the female performing most of the incubation. Fledglings remain dependent on their parents for several months post-fledging.

The Black-chested Snake Eagle may be confused with the Martial Eagle but is significantly smaller with different coloring and flight patterns. Juvenile Martial Eagles may be mistaken for juvenile Crowned Eagles but differ in wing and tail proportions.

Martial Eagles are opportunistic predators, with a diet comprising mammals, birds, and reptiles. They are known for hunting from a high soar, using their keen eyesight to spot prey from several kilometers away.

The Martial Eagle is currently classified as Endangered by the IUCN, with populations declining due to factors such as persecution, habitat destruction, and collisions with power lines. Conservation efforts focus on education and the expansion of protected areas.

18-4-2018 CHOBE NAT PARK, BOTSWANA - LITTLE BEE-EATER (Merops pasillas)

The little bee-eater (Merops pusillus) is a bird species in the bee-eater family, Meropidae. They are found in Sub-Saharan Africa. They should not be confused with the little green bee-eater (Merops orientalis). Migration is limited to seasonal movements depending on rainfall patterns.

Members of this species, like other bee-eaters, are rich and brightly-coloured slender birds. They have green upper parts, yellow throats, black gorgets, and rich brown upper breasts fading to buffish ochre on the belly. Their wings are green and brown. Their beaks and legs are black. They reach a length of 15–17 cm, which makes them the smallest African bee-eater. Sexes are alike. Often silent, their call is a soft "seep".

These are abundant and tame birds, familiar throughout their range. There have been estimated to be between 60-80 million little bee-eaters. They breed in open country with bushes, preferably near water. Just as the name suggests, bee-eaters predominantly eat insects, especially bees, wasps and hornets, who are caught in the air by sorties from an open perch. This species often hunts from low perches, maybe only a metre or less high. Before eating their meal, a bee-eater removes the stinger by repeatedly hitting the insect on a hard surface.

18-4-2018 CHOBE NAT PARK, BOTSWANA - GREEN WOOD HOOPOE (Phoeniculus purpureus)

The green wood hoopoe, Phoeniculus purpureus, is a striking bird native to the African continent. It is a large species, reaching up to 44 cm in length, and is adorned with a lustrous metallic dark green plumage. The bird's back is a resplendent purple, and it boasts a remarkably long, diamond-shaped tail of the same hue. Its wings are marked with distinctive white patterns, and the tail edges are decorated with white chevrons, making it a sight to behold.

Upon sighting, one can identify the green wood hoopoe by its long, thin, and curved red bill, which is a prominent feature against its dark plumage. Both sexes appear similar, though the immature birds can be distinguished by their black bills. The white markings on the wings and tail are key identifiers for this species.

The green wood hoopoe is a common resident of sub-Saharan Africa's forests, woodlands, and even suburban gardens, where it can be seen foraging and socializing in groups.

This bird has a wide range across sub-Saharan Africa, with its presence noted from Senegal to South Africa. It is divided into six recognized subspecies, each occupying different geographical regions within the continent.

The green wood hoopoe is known for its social nature, often found in flocks that can number up to a dozen individuals. Only one pair within these groups breeds, while the others assist in communal activities. Its behavior is characterized by its loud and distinctive kuk-uk-uk-uk-uk call, which can be heard echoing through its habitat.

17-4-2018 CHOBE NAT PARK, BOTSWANA - GREATER BLUE EARED STARLING (Lamprotornis chalybaeus)

The greater blue-eared starling, or Lamprotornis chalybaeus, is a striking bird adorned in glossy blue-green plumage with a purple-blue belly and a distinctive blue ear patch. This bird measures approximately 22 cm in length and sports a short tail. The iris of this species is a vivid yellow or orange, adding to its captivating appearance. Both sexes exhibit similar coloration, though juveniles can be distinguished by their duller feathers and blackish-brown underparts.

When identifying the greater blue-eared starling, look for its glossy blue-green upperparts and purple-blue belly. The blue ear patch is a key feature, along with its bright yellow or orange iris. Juveniles are less lustrous and have darker underparts. This species can be confused with the lesser blue-eared starling, but the latter's blue belly does not extend forward of the legs.

The greater blue-eared starling is commonly found in open woodland environments, where it thrives and breeds.

This bird has a broad range across the African continent, from Senegal in the west, stretching east to Ethiopia, and then southward through eastern Africa to northeastern South Africa and Angola. It is known to undertake seasonal migrations within this range.

The greater blue-eared starling is a highly social bird, often seen in large flocks that may include other starling species. It is also known to roost communally in reedbeds, thorn bushes, or acacia trees, sometimes sharing these spaces with other birds.

The vocal repertoire of the greater blue-eared starling includes a variety of musical and grating calls. A commonly heard call is a nasal "squee-ar," which is quite distinctive.

Breeding pairs of greater blue-eared starlings make their nests in tree holes, which can be naturally occurring or previously excavated by woodpeckers or barbets. They are also known to utilize the large stick nests of the sacred ibis or Abdim's stork. Their nests typically contain three to five greenish-blue eggs adorned with brown or purple spots. These eggs hatch after about 13–14 days, and the fledglings leave the nest approximately 23 days post-hatching. The species is occasionally parasitized by the great spotted cuckoo and, less frequently, by the greater honeyguide.

An omnivorous bird, the greater blue-eared starling's diet is predominantly insectivorous, foraging mainly on the ground for a variety of invertebrates. It also consumes seeds and berries, with a particular fondness for figs. Additionally, these starlings are known to perch on livestock, picking off insects disturbed by the animals and sometimes removing ectoparasites.

The IUCN Red List classifies the greater blue-eared starling as Least Concern, indicating that the species does not currently face any significant threats to its survival.

17-4-2018 CHOBE NAT PARK, BOTSWANA - COPPERY TAILED COUCAL (Centropus cupreicaudus)

It boasts a distinctive curved beak and a long, broad tail that is characteristic of its species. The adult's plumage is a study in contrasts, with a glossy black head and upperparts, and a contrasting white or cream underbelly. The rump glistens with a coppery sheen, while the tail is a dark brownish-black. In contrast, the immature birds display pale streaks on their heads and barred flight feathers, hinting at their youth.

When identifying the Coppery-tailed Coucal, look for its sizeable curved beak and the long tail. The adult's black and white plumage with a coppery rump is distinctive, while the immature bird can be recognized by the streaks on its head and the barring on its flight feathers. Males are marginally smaller than females, a subtle difference that may aid in identification.

This species is most commonly found in the swamplands and dense vegetation that flourish near rivers. It also inhabits inundated floodplains and areas adjacent to seasonal lakes, thriving in these wetland environments.

The Coppery-tailed Coucal's range extends across south-central Africa, from Angola in the west to southwestern Tanzania, and includes northern Botswana and the Caprivi Strip in Namibia. Its territory spans an impressive 1,750,000 square kilometers.

17-4-2018 CHOBE NAT PARK, 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.

17-4-2018 CHOBE NAT PARK, BOTSWANA - EAST AFRICAN HARRIER HAWK (Polyboroides typus ssp. typus)

The East African Harrier Hawk, also known as the African Harrier-Hawk, is a fascinating raptor with several unique features. It's known for its double-jointed legs that allow it to reach into tight spaces like tree cavities and rock crevices to find prey. They are also opportunistic feeders, adapting their diet to include a variety of foods, from small vertebrates to fruits. Additionally, they are skilled nest robbers, often raiding nests of other birds for eggs and chicks. 

They have Double-Jointed Legs:

This unique adaptation allows them to maneuver their legs in ways that other raptors cannot, making them excellent at extracting prey from difficult-to-reach places. 

Omnivorous Diet:

While they are known for raiding nests, they also consume a variety of other foods, including rodents, bats, birds, insects, and even fruits. 

Solitary Hunters:

They are generally solitary birds, but they do engage in courtship displays, sometimes soaring high in the sky and vocalizing, according to Birda. 

They can be found in a variety of habitats across sub-Saharan Africa, including woodlands, forests, and even near human settlements. 

17-4-2018 CHOBE NAT PARK, BOTSWANA - AFRICAN BUSH ELEPHANT (Loxodonta africana)

The African bush elephant (Loxodonta africana) is one of two living African elephant species. It is the largest living terrestrial animal and is distributed across 37 African countries. Since 2021, it 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.

The African bush elephant has grey skin with scanty hairs. Its large ears cover the whole shoulder and can grow as large as 2 m × 1.5 m (6 ft 7 in × 4 ft 11 in). Its large ears help to reduce body heat; flapping them creates air currents and exposes large blood vessels on the inner sides to increase heat loss during hot weather. The African bush elephant's ears are pointed and triangular-shaped. Its occipital plane slopes forward. Its back is shaped markedly concave. Its sturdy tusks are curved out and point forward. The trunk is a prehensile extension of the upper lip and nose. Short tactile hair grows on the trunk, which has two finger-like processes on the tip. This highly sensitive organ is innervated primarily by the trigeminal nerve and is thought to be manipulated by about 40,000-60,000 muscles. Because of this muscular structure, the trunk is so strong that elephants can use it for lifting about 3% of their own body weight. They use it for smelling, touching, feeding, drinking, dusting, sound production, loading, defending, and attacking. Both sexes have tusks, which erupt when they are 1-3 years old and grow throughout life. Tusks grow from deciduous teeth known as tushes that develop in the upper jaw and consist of a crown, root, and pulpal cavity, which are completely formed soon after birth. Tushes reach a length of 5 cm (2.0 in). The tusks of males grow faster than the tusks of females.

African bush elephants occur in Sub-Saharan Africa including Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, and Angola. They move between a variety of habitats, including forests, dry and seasonally flooded grasslands, woodlands, shrubland, and wetlands to mountain slopes. In Mali and Namibia, they also inhabit desert and semi-desert areas.

Savanna elephants live in a rather complex social hierarchy. These animals gather into family units, consisting of about 10 females and their offspring. Reaching maturity, male calves usually leave the family unit, forming bachelor herds or living solitarily. As a general rule, males socialize with these family groups only when mating. Meanwhile, several family herds may gather together, making up a 'clan'. Each clan is dominated by a female matriarch and can consist of as many as several hundred elephants. African bush elephants are very careful and protective animals. Allomothering is a common practice in this species: females can raise calves of other females of their herd. They protect and care for the calves of the herd, while all adults are sleeping. If a calf strays too far, these allomothers are responsible for retrieving the baby. These active animals are constantly on the move. These elephants forage during the daytime hours, wandering the home range of their herd. Savanna elephants freely communicate with conspecifics both verbally and non-verbally.

They use it for smelling, touching, feeding, drinking, dusting, sound production, loading, defending, and attacking. Both sexes have tusks, which erupt when they are 1-3 years old and grow throughout life. Tusks grow from deciduous teeth known as tushes that develop in the upper jaw and consist of a crown, root, and pulpal cavity, which are completely formed soon after birth. Tushes reach a length of 5 cm (2.0 in). The tusks of males grow faster than the tusks of females.

The White-crowned Lapwing, also known as the White-headed Lapwing, White-headed Plover, or White-crowned Plover, is a medium-sized wader that presents a striking appearance. Its upper body is adorned with a brown back, while the wings and tail exhibit a bold black and white pattern. The underparts are a clean white. The head is particularly distinctive with a grey base, a brilliant white crown, and a white foreneck. Adding to its unique visage are the yellow eyering, facial wattles, and legs. Both sexes and juveniles share a similar plumage, making them indistinguishable in the field.

When attempting to identify the White-crowned Lapwing, look for the unmistakable combination of its white crown, grey head, and the contrasting black and white patterns on its wings and tail. The yellow eyering and wattles are also key features that aid in its identification.

This species is typically found in tropical Africa, favoring habitats near large rivers. It thrives in areas where sand or shingle is exposed, providing suitable breeding grounds.

The White-crowned Lapwing is a resident bird throughout tropical Africa, maintaining a presence year-round near its preferred riverine environments.

The White-crowned Lapwing is known for its breeding behavior, where it lays 2-3 eggs in a ground scrape near rivers. It is fiercely protective of its nest and young, defending them with vigor against any potential threats, regardless of size. Outside of breeding season, it is common to see these birds feeding in small flocks, where they forage for insects and other small invertebrates.

17-4-2018 CHOBE RIVER, BOTSWANA - WATER THICK NEE (Barhinus Vermiculatus)

The Water Thick-knee, also known as the Water Dikkop (Burhinus vermiculatus), presents a striking figure with its 38 to 41 cm (15–16 in) stature and a weight range of 293–320 g (10.3–11.3 oz). This bird is characterized by a robust bill, black with a hint of yellow at the base, broad and blunt wings, and a rather short tail.

When identifying the Water Thick-knee, look for its heavy bill with a yellow base, which is quite distinctive. The wings are broad and blunt, which can be observed when the bird stretches them. The tail is short, which is noticeable when the bird is in flight or when it fans its tail feathers.

The Water Thick-knee is typically found along the edges of lakes, estuaries, and rivers. It also frequents mangroves and some sheltered beaches, often requiring nearby bushes or woodlands for shelter. Its habitat range extends from sea level up to 1,800 m (5,900 ft).

This species enjoys a widespread distribution across sub-Saharan Africa, with sightings reported in countries such as Angola, Botswana, Burkina Faso, and many others, all the way to South Africa.

The Water Thick-knee is a nocturnal terrestrial feeder, often venturing up to 1 km (0.62 mi) away from water to forage. It is known for its unique nesting behavior, often laying its eggs adjacent to or directly on top of Nile crocodile nests, engaging in a symbiotic mutualism with the crocodiles.

The Water Thick-knee is known to be vocal, especially when acting as a sentry for its nest or the crocodile nests it shares. Its calls are used to alert the crocodile of potential threats.

Breeding typically occurs in the dry season or early rainy season. The Water Thick-knee is monogamous, with both parents diligently guarding the nest and brooding the eggs. The nest is a simple scrape in the ground, and the clutch consists of two sandy-yellow eggs. Incubation lasts for 22-25 days, with both parents sharing the responsibility of feeding the young.

The Water Thick-knee can easily be confused with the Spotted Thich-knee.

The diet of the Water Thick-knee includes insects, crustaceans, and mollusks, which it forages for during the night.

The Water Thick-knee is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of population decline.

17-4-2018 CHOBE RIVER, BOTSWANA - SQUACCO HERON (Ardeola ralloides)

The Squacco Heron is a tawny buff brown heron with a streaked head and back, and in breeding a black and white mane.

Adult: The adult nonbreeding Squacco Heron has a head that is finely streaked in black, brown, and grey, forming a modest crown but no elongated plumes in nonbreeding season. The relatively large and powerful bill is pale green yellow with a black tip and top. The lores are dull yellow green. The irises are yellow. The hind neck, like the head, is finely streaked in black, brown and grey. The upperparts are buff brown with slight tawny tinge. The wings are white and are mostly concealed at rest by the back plumes. The plumes are shorter than in the breeding season. The rump and tail are white. Foreneck and breast are bright buff coarsely streaked in dark brown. The remaining underparts are white. The relatively short legs and the feet are dull yellow green.

In breeding plumage, the upper parts become brighter and deeper. The crown is a mane of yellow buff or straw-colored feathers. The crown feathers are slightly elongated (1-5 cm) and are bordered with black. Several very elongated feathers (13-14 cm long) occur on the back of the crown. These are white bordered with black, and extend over the upper back. The lores are green or blue. The lower neck and back plumes are golden to cinnamon buff. The foreneck and breast are red gold. During courtship, the bill becomes bright blue except for the dark to black tip. The lores turn briefly blue before reverting via emerald to yellow green. The irises in courtship are richer yellow. The back is pink brown, with longest back feathers being golden and drooping over the wings. The legs are bright red in courtship, fading to pink after pairing. The other soft parts colors return to normal after the eggs are laid.

Variation: The sexes are alike. Geographic variation is not recognized taxonomically. South and central African birds were once considered recognized as the subspecies paludivaga.

17-4-2018 CHOBE RIVER, BOTSWANA - AFRICAN PIED KINGFISHER (Ceryle rudis ssp rudis)

The pied kingfisher (Ceryle rudis) is a striking water kingfisher, known for its black and white plumage and distinctive crest. It is a medium-sized bird, approximately 25 cm in length, with a white face featuring a black mask and a white supercilium.
