22-4-2018 OKAVANGO DELTA, BOTSWANA - FLOWER OF AN HOUR (Hibiscus trionum)

Hibiscus trionum, commonly called flower-of-an-hour, bladder hibiscus, bladder ketmia, bladder weed, puarangi and venice mallow, is an annual plant native to the Old World tropics and subtropics. It has spread throughout southern Europe both as a weed and cultivated as a garden plant. It has been introduced to the United States as an ornamental where it has become naturalized as a weed of cropland and vacant land, particularly on disturbed ground.

The plant grows to a height of 20–50 centimetres (8–20 in), sometimes exceeding 80 cm (30 in), and has white or yellow flowers with a purple centre. In the deeply pigmented centre of the flower, the surface features striations, which have been the subject of controversy about whether they act as a diffraction grating, creating iridescence.

The pollinated but unripe seedpods look like oriental paper lanterns, less than 25 mm (1 in) across, pale green with purple highlights.

The flowers of Hibiscus trionum can set seed via both outcrossing and self-pollination. During the first few hours after anthesis, the style and stigma are erect and receptive to receive pollen from other plants. In the absence of pollen donation, the style bends and makes contact with the anthers of the same flower, inducing self-pollination. Although outcrossing plants seem to perform better than self-pollinating plants, this form of reproductive assurance might have contributed to the success of H. trionum plants in several environments.

20-4-2018 OKAVANGO DELTA, BOTSWANA - ZAMBESI CRESTED BARBET (Trachyphonus vaillantii ssp. nobilis)

The crested barbet, Trachyphonus vaillantii, is a small, vibrantly colored bird, easily recognized by its thick bill and speckled plumage. Its face is a mosaic of yellow and red, adorned with a modest black crest. The belly mirrors the face with yellow and red speckles, while the wings are black with white dots. A striking black band encircles its neck. The bird's overall yellow hue, peppered with black and white feathers and red at the body's end, provides excellent camouflage in its natural bush habitat. The crested barbet's call is a distinctive trill.

When identifying the crested barbet, look for its unique coloration and markings. The combination of a yellow and red speckled face, a small black crest, and a broad black neck band are key features. The bird's trilling call can also serve as an auditory clue to its presence.

The crested barbet thrives in a variety of environments, including forests, savannahs, suburban gardens, woodland thickets, and areas near watercourses.

This species is widely distributed across sub-Saharan Africa, with sightings confirmed in Angola, Botswana, Burundi, the Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe.

21-4-2018 NXEBEGA LODGE OKAVANGA DELTA, BOTSWANA - AFRICAN LEOPARD (JUVENILE) COURTESY MRS VALERIE FISHER

The African Leopard is widely distributed across Africa, but the population of this sub-species is decreasing and it has been classified as Vulnerable by IUCN’s Red List.

Like most felines, African Leopard are incredibly athletic predators and they can run up to 58 miles per hour and leap an impressive 6 metres forward through the air.

The coat of the African Leopard is covered with rosette-shaped markings. The rosettes on the leopards coat do not contain spots, unlike those of their new world relative the Jaguar. The average lifespan of African Leopard is 10 to 12 years in the wild.

African Leopard have suffered from habitat loss and fragmentation, increased illegal wildlife trade, decline in prey and poorly managed trophy hunting.

Prey species are increasingly under threat from an unsustainable bushmeat trade across large parts of Africa’s savannas. Leopards are also killed illegally for their widely sought-after skins and other body parts used for ceremonial purposes.

African Leopard have limited levels of ecological resilience to human-caused habitat fragmentation, and as a result are more restricted to conservation areas – future decline is anticipated unless conservation efforts are undertaken.

African leopards inhabited a wide range of habitats within Africa, from mountainous forests to grasslands and savannahs, excluding only extremely sandy deserts. They used to live in most of sub-Saharan Africa, occupying both rainforest and arid desert habitats. African leopards successfully adapted to altered natural habitats and settled environments in the absence of intense persecution and they have often been seen close to major cities. But already in the 1980s, they have become rare throughout much of West Africa. Now, African leopards remain patchily distributed within historical limits. During surveys in 2013, they were recorded in Gbarpolu County and Bong County in the Upper Guinean forests of Liberia. They are rare in North Africa. A relict population persists in the Atlas Mountains of Morocco, in forest and mountain steppe, where the climate is temperate to cold. In 2016, an African leopard was recorded for the first time in a semi-arid area of Yechilay in northern Ethiopia.

19-4-2018 NXEBEGA LODGE OKAVANGA DELTA, BOTSWANA - MAGPIE SHRIKE (Urolestes melanoleucus) COURTESY OF MRS VALERIE FISHER

The Magpie Shrike, also known as the African Long-tailed Shrike, is a striking bird belonging to the family Laniidae. It is characterized by its elongated tail and contrasting black and white plumage, reminiscent of the European magpie, though they are not closely related.

This species can be identified by its long tail, which is almost the length of its body, and its black and white coloration. The bird's back is predominantly black, with white underparts and a white patch on the wing. The head is black with a white belly and flanks, and the eyes are keen and alert.

The Magpie Shrike is native to the grasslands of eastern and southeastern Africa. It thrives in dry savannah, moist savannah, and subtropical or tropical dry shrubland, preferring open areas with scattered acacia trees, close-grazed turf, and bare ground.

This bird is found across a range of African countries, including Angola, Botswana, Eswatini, Kenya, Mozambique, Namibia, South Africa, Tanzania, Zambia, and Zimbabwe. It is common in places within this range.

The Magpie Shrike is a gregarious and social bird, often found in noisy groups of about a dozen. These groups occupy a home range of several tens of hectares. During the breeding season, they display a variety of behaviors such as bowing, tail flicking, wing raising, and whistling to communicate and establish bonds.

19-4-2018 NXEBEGA LODGE OKAVANGA DELTA, BOTSWANA - SOUTHERN GREY HEADED KINGFISHER (Halcyon leucocephala ssp pallidiventris) COURTESY OF MRS VALERIE FISHER

The Southern Grey-headed Kingfisher, Halcyon leucocephala ssp pallidiventris, presents a striking figure with its pale grey head, black mantle, and a vivid blue rump. Its wings and tail share this blue brilliance, while the chestnut underparts add a warm contrast. The beak, long and sharp, is a notable red. This bird averages 21 cm in length, a size that allows it to maneuver with agility in its preferred habitats.

When identifying the Southern Grey-headed Kingfisher, look for the combination of its grey head and chestnut belly, which distinguishes it from similar species. The subspecies H. l. pallidiventris has a darker grey head and paler chestnut underparts. The bird's bright blue rump, wings, and tail are also key identification features.

This kingfisher favors woodlands, scrub, and cultivated areas, and can be found at altitudes up to 2,200 meters. It is often seen near water, though it does not rely on aquatic environments.

.

The species is widely distributed across tropical and semi-tropical regions of Africa and the Arabian Peninsula, from the Cape Verde Islands and Mauritania to Ethiopia, Somalia, southern Arabia, and southward to South Africa.

.

The Grey-headed Kingfisher is typically solitary or found in pairs. It is known for perching motionless on a branch for extended periods, keenly observing the ground for insects or small lizards before striking. It is protective of its nesting sites, often dive-bombing potential threats such as monitor lizards.

.

The song of the Grey-headed Kingfisher is a series of notes that ascend, descend, and then ascend again, growing increasingly strident. Its warning call is a sharp "tchk, tchk, tchk, tchk."

This kingfisher nests in holes within steep riverbanks and exhibits aggressive behavior in defending its nest.

The Grey-headed Kingfisher may be confused with the Brown-hooded Kingfisher due to its similar size and coloration, but the latter has a red and black bill. It also resembles the Woodland Kingfisher, which lacks the chestnut belly and has more extensive cyan feathers on the back.

It primarily feeds on insects and small lizards, which it hunts by watching from a perch before diving down to capture its prey.

The Grey-headed Kingfisher is currently listed as Least Concern on the IUCN Red List, indicating that it is not at immediate risk of widespread decline.

9-5-2018 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (JUVENILE) (Himantopus himantopus)

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.

Black-winged Stilts are often seen foraging in shallow waters, gracefully picking insects and crustaceans from the surface. They are known to nest in small groups, sometimes alongside avocets, and exhibit a variety of courtship behaviors, including intricate displays and duets.

The flight call of the Black-winged Stilt is a sharp and clear kleek, typically heard during its aerial maneuvers.

Nests are simple bare spots on the ground near water. These birds are communal nesters and may breed in loose colonies. They have been known to breed as far north as Britain, with recent successful breeding events recorded in Southern and Northern England.

The Black-winged Stilt can be confused with other stilt species, such as the Black-necked Stilt (H. mexicanus) in the Americas, the White-backed Stilt (H. melanurus), and the Pied Stilt (H. leucocephalus) in Australasia and New Zealand.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

9-5-2018 RACO DE OLLA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)

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.

Their diet consists mainly of insects and crustaceans, which they deftly pick from the water's surface or from wet sand.

The IUCN lists the Black-winged Stilt as Least Concern, indicating a stable global population. However, they are protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds, highlighting the importance of international cooperation in their conservation.

9-5-2018 RACO DE OLLA, VALENCIA - PIED AVOCET (Recurvirostra avosetta)

The pied avocet (Recurvirostra avosetta) is a large black and white wader in the avocet and stilt family, Recurvirostridae. They breed in temperate Europe and across the Palearctic to Central Asia then on to the Russian Far East. It is a migratory species and most winter in Africa or southern Asia. Some remain to winter in the mildest parts of their range, for example in southern Spain and southern England. The pied avocet is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.

The pied avocet was one of the many bird species originally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae, where it was given the binomial name of Recurvirostra avosetta. This species gets its English and scientific names from the Venetian word avosetta. It appeared first in Ulisse Aldrovandi's Ornithologia (1603). While the name may refer to black and white outfits once worn by European advocates or lawyers, the actual etymology is uncertain. Other common names include black-capped avocet, Eurasian avocet or just avocet.

It is one of four species of avocet that make up the genus Recurvirostra. The genus name is from Latin recurvus, "curved backwards" and rostrum, "bill". A 2004 study combining genetics and morphology showed that it was the most divergent species in the genus.

The pied avocet is a striking white wader with bold black markings. Adults have white plumage except for a black cap and black patches in the wings and on the back. They have long, upturned bills and long, bluish legs. It is approximately 16.5–17.75 in (41.9–45.1 cm) in length of which the bill is approximately 2.95–3.35 in (7.5–8.5 cm) and the legs are approximately 3–4 in (7.6–10.2 cm). Its wingspan is approximately 30–31.5 in (76–80 cm). Males and females look alike. The juvenile resembles the adult but with more greyish and sepia tones.

The call of the avocet is a far-carrying, liquid, melodious kluit kluit.

These birds forage in shallow brackish water or on mud flats, often scything their bills from side to side in water (a feeding technique that is unique to the avocets). They mainly eat crustaceans and insects.

Their breeding habitat is shallow lakes with brackish water and exposed bare mud. They nest on open ground, often in small groups, sometimes with other waders. Three to five eggs are laid in a lined scrape or on a mound of vegetation.

9-5-2018 RACO DE OLLA, VALENCIA - COMMON SANDPIPER (Actitis hypoleucos)

The Common Sandpiper, Actitis hypoleucos, is a small wader of the Palearctic region, easily recognized by its greyish-brown upperparts and pristine white underparts. Adults typically measure between 18-20 cm in length, with a wingspan of 32-35 cm. They possess short, dark-yellowish legs and feet, and a bill that is pale at the base with a dark tip.

In the field, look for the Common Sandpiper's distinctive stiff-winged flight pattern, just above the water's surface. During the non-breeding season, they appear duller and exhibit more noticeable barring on the wings, which is most visible at close range. Juveniles display heavier barring above and buff edges to their wing feathers. The species can be differentiated from the similar Spotted Sandpiper by its darker legs and feet and the crisper wing pattern, especially in flight.

These birds are often found near freshwater sources, where they nest on the ground in close proximity to the water's edge.

The Common Sandpiper breeds across much of temperate and subtropical Europe and Asia. It is a migratory bird, wintering in Africa, southern Asia, and Australia. During migration, large numbers may congregate in stop-over locations such as Palau in Micronesia.

Common Sandpipers are typically solitary or found in small groups. They may form larger flocks during migration or at breeding season roosts but seldom join multispecies flocks.

When breeding, these birds nest on the ground near freshwater. A notable behavior is the young's ability to cling to a parent's body, being flown to safety when threatened.

The Spotted Sandpiper (A. macularia) is the most similar species, especially in non-breeding plumage. However, the Common Sandpiper's darker legs and more defined wing pattern in flight help distinguish it.

The Common Sandpiper forages by sight, picking up small food items such as insects, crustaceans, and other invertebrates from the ground or shallow water. It is also known to catch insects in flight.

The species is widespread and common, thus classified as Least Concern on the IUCN Red List. However, it is considered vulnerable in some Australian states. The Common Sandpiper is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA).

9-5-2018 RACO DE OLLA, VALENCIA - COMMON SHELDUCK (MALE) (Tadorna tadorna)

The common shelduck, Tadorna tadorna, is a waterfowl species that graces the Euro-Siberian region with its presence. It is a medium-sized bird, akin to a small, short-necked goose, and is quite the sight with its white plumage contrasted by chestnut patches and a black underbelly. The head and neck are a dark, iridescent green, and the bill is a reddish-pink, with the male sporting a conspicuous knob on the forehead during the breeding season. Pink feet complete the ensemble, making this bird a striking figure in its habitat.

To identify the common shelduck, look for the distinctive reddish-pink bill and pink feet. The male, especially in breeding plumage, has a bright red bill with a prominent knob. The female is slightly smaller and has white facial markings. Both sexes have a white body with chestnut patches, a black belly, and a dark green head and neck. In flight, the green and chestnut secondary feathers become visible, contrasting with the predominantly white underwings.

The common shelduck is found in a variety of wetland habitats, including temperate lakes and rivers, as well as estuaries and tidal mudflats in winter. It has a particular fondness for salt marshes and estuaries and is known to breed in rabbit burrows, tree holes, and even haystacks.

This species is widespread across temperate Eurasia. It breeds in temperate regions and migrates to subtropical areas for wintering. Some populations remain resident in the westernmost parts of Europe, while others undertake movements to moulting grounds like the Wadden Sea.

The common shelduck is a sociable bird, often seen in large moulting flocks that can number up to 100,000 individuals. It is known for leaving its young in crèches supervised by a few adults. The species is also covered by the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), highlighting its ecological importance.

The vocalization of the common shelduck is a loud, unmistakable honk, which can be heard over considerable distances.

During the breeding season, the male's bill becomes particularly vibrant, and the species is known to nest in a variety of locations, from rabbit burrows to tree holes.

While the common shelduck is quite distinctive, it could potentially be confused with other shelduck species. However, its unique coloration and size generally make it easy to distinguish.

The common shelduck feeds on a variety of items, including mollusks and small aquatic creatures, which it often forages for in the mudflats during low tide.

The IUCN Red List classifies the common shelduck as Least Concern, indicating that, currently, there are no immediate threats to its population numbers on a global scale.

9-5-2018 DEVESA, VALENCIA - BLACK TAILED GODWIT (limosa limosa)

The black-tailed godwit (Limosa limosa) is a large, long-legged, long-billed shorebird first described by Carl Linnaeus in 1758. It is a member of the godwit genus, Limosa. There are four subspecies, all with orange head, neck and chest in breeding plumage and dull grey-brown winter coloration, and distinctive black and white wingbar at all times.

Its breeding range stretches from Iceland through Europe and areas of central Asia. Black-tailed godwits spend (the northern hemisphere) winter in areas as diverse as the Indian subcontinent, Australia, New Zealand, western Europe and west Africa. The species breeds in fens, lake edges, damp meadows, moorlands and bogs and uses estuaries, swamps and floods in (the northern hemisphere) winter; it is more likely to be found inland and on freshwater than the similar bar-tailed godwit. The world population is estimated to be 634,000 to 805,000 birds and is classified as Near Threatened. The black-tailed godwit is the national bird of the Netherlands.

The black-tailed godwit was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax limosa. It is now placed with three other godwits in the genus Limosa that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The name Limosa is from Latin and means "muddy", from limus, "mud". The English name "godwit" was first recorded in about 1416–17 and is believed to imitate the bird's call.

Four subspecies are recognised:

L. l. islandica – Brehm, 1831: the Icelandic black-tailed godwit, which breeds mostly in Iceland, but also on the Faeroe Islands, the Shetland and the Lofoten Islands. It has a shorter bill, shorter legs and more rufous coloration extending onto the belly, compared to limosa.

L. l. limosa – (Linnaeus, 1758): the European black-tailed godwit, which breeds from western and central Europe to central Asia and Asiatic Russia, as far east as the Yenisei River. Its head, neck and chest are pale orange.

L. l. melanuroides – Gould, 1846: the Asian black-tailed godwit, which breeds in Mongolia, northern China, Siberia and Far Eastern Russia. Its plumage is similar to islandica, but the bird is distinctly smaller.

L. l. bohaii – Zhu, Piersma, Verkuil & Conklin, 2020:[10] assumed to breed in Russian Far East; non-breeding in northeast China, Hong Kong, Vietnam, Peninsular Malaysia

The black-tailed godwit is a large wader with long bill (7.5 to 12 cm (3.0 to 4.7 in) long), neck and legs. During the breeding season, the bill has a yellowish or orange-pink base and dark tip; the base is pink in winter. The legs are dark grey, brown or black. The sexes are similar, but in breeding plumage, they can be separated by the male's brighter, more extensive orange breast, neck and head. In winter, adult black-tailed godwits have a uniform brown-grey breast and upperparts (in contrast to the bar-tailed godwit's streaked back). Juveniles have a pale orange wash to the neck and breast.

In flight, its bold black and white wings and white rump can be seen readily. When on the ground it can be difficult to separate from the similar bar-tailed Godwit, but the black-tailed godwit's longer, straighter bill and longer legs are diagnostic. Black-tailed godwits are similar in body size and shape to bar-taileds, but stand taller.

It measures 42 cm (17 in) from bill to tail with a wingspan of 70–82 cm (28–32 in). Males weight around 280 g (9.9 oz) and females 340 g (12 oz).[12] The female is around 5% larger than the male,[8] with a bill 12–15% longer.

The most common call is a strident weeka weeka weeka.

A study of black-tailed godwits in the Netherlands found a mortality rate of 37.6% in the first year of life, 32% in the second year, and 36.9% thereafter.

Black-tailed godwits have a discontinuous breeding range stretching from Iceland to the far east of Russia. Their breeding habitat is river valley fens, floods at the edges of large lakes, damp steppes, raised bogs and moorlands. An important proportion of the European population now uses secondary habitats: lowland wet grasslands, coastal grazing marshes, pastures, wet areas near fishponds or sewage works, and saline lagoons. Breeding can also take place in sugar beet, potato and rye fields in the Netherlands and Germany.

In spring, black-tailed godwits feed largely in grasslands, moving to muddy estuaries after breeding and for winter. On African wintering grounds, swamps, floods and irrigated paddy fields can attract flocks of birds. In India, inland pools, lakes and marshes are used, and occasionally brackish lakes, tidal creeks and estuaries.

Godwits from the Icelandic population winter mainly in the United Kingdom, Ireland, France and the Netherlands, though some fly on to Spain, Portugal and perhaps Morocco. Birds of the limosa subspecies from western Europe fly south to Morocco and then on to Senegal and Guinea-Bissau. Birds from the eastern European populations migrate to Tunisia and Algeria, then on to Mali or Chad. Young birds from the European populations stay on in Africa after their first winter and return to Europe at the age of two years. Asian black-tailed godwits winter in Australia, Taiwan, the Philippines, Indonesia, and Papua New Guinea.

Black-tailed godwits are much more likely to be found on inland wetlands than the more coastal bar-tailed godwit. They migrate in flocks to western Europe, Africa, south Asia and Australia. Although this species occurs in Ireland and Great Britain all year-round, they are not the same birds. The breeding birds depart in autumn, but are replaced in winter by the larger Icelandic race. These birds occasionally appear in the Aleutian Islands and, rarely, on the Atlantic coast of North America.

Black-tailed godwits are mostly monogamous; although it was not recorded in a four-year study of 50–60 pairs, bigamy was considered "probably frequent". A study of the Icelandic population showed that despite spending winter apart, pairs are reunited on their breeding grounds within an average of three days of each other. If one partner does not arrive on time, 'divorce' occurs. They nest in loose colonies. Unpaired males defend a temporary territory and perform display flights to attract a mate. Several nest scrapes are made away from the courtship territory, and are defended from other godwits. Once eggs are laid, an area of 30–50 m (98–164 ft) around the nest is defended. The nest is a shallow scrape on the ground, usually in short vegetation. The eggs may be hidden with vegetation by the incubating parent.

The single brood of three to six eggs, coloured olive-green to dark brown, measure 55 mm × 37 mm (2.2 in × 1.5 in) and weigh 39 g (1.4 oz) each (of which 6% is shell). Incubation lasts 22–24 days and is performed by both parents. The young are downy and precocial and are brooded while they are small and at night during colder weather. After hatching, they are led away from the nest and may move to habitats such as sewage farms, lake edges, marshes and mudflats. The chicks fledge after 25–30 days.

Black-tailed godwit productivity varies, positively, with spring temperatures. However, during extreme events, such as a volcanic eruption, complete breeding failures can occur.

They mainly eat invertebrates, but also aquatic plants in winter and on migration. In the breeding season, prey includes beetles, flies, grasshoppers, dragonflies, mayflies, caterpillars, annelid worms and molluscs. Occasionally, fish eggs, frogspawn and tadpoles are eaten. In water, the most common feeding method is to probe vigorously, up to 36 times per minute, and often with the head completely submerged. On land, black-tailed godwits probe into soft ground and also pick prey items from the surface.

18-4-2018 CHOBE NAT PARK, BOTSWANA - COMMON IMPALA (MALE) (Aepyceros melampus ssp. melampus) COURTESY OF MRS VALERIE FISHER

The impala (Aepyceros melampus) is a medium-sized antelope that is found in Africa. It was first described to European audiences by German zoologist Hinrich Lichtenstein in 1812. Active mainly during the day, the impala may be gregarious or territorial depending upon the climate and geography. The impala is known for two characteristic leaps that constitute an anti-predator strategy.

Impala is an elegant and magnificent species of antelope. The animal has slender body with the identifying "M"-like marking on the rear. This medium-sized antelope possesses thin, pointed horns with tips, lying far apart from each other. Males of this species are identified by the characteristic "S"-like horns. The elegant limbs of these animals have scent glands behind the ankles. The overall coloration of their fur is red-brown with paler sides. In addition, they have black and white colored areas on their body. Thus, the tail, belly, chin, lips, inside ears as well as the lines above the eyes are colored with white. Meanwhile, black bands cover their thighs, tail, forehead and ear tips.

18-4-2018 CHOBE NAT PARK, BOTSWANA - SOUTHERN GREATER KUDU (FEMALE) (Tragelaphus Strepsiceros) COURTESY OF MRS VALERIE FISHER

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).

18-4-2018 CHOBE NAT PARK, BOTSWANA - COPPERY TAILED COUCAL (Centropus cupreicaudus) COURTESY OF MRS VALERIE FISHER

The Coppery-tailed Coucal, a member of the cuckoo family, is a striking bird approximately 48 cm in length. 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.

A territorial bird, the Coppery-tailed Coucal is most active in the early morning and evening. It forages on land, preying on a diverse diet that includes amphibians, fish, small birds, reptiles, and rodents, as well as invertebrates like grasshoppers, crabs, and snails. Remarkably, it also scavenges for carrion and consumes some plant matter. During the breeding season, it exhibits monogamous behavior, with both parents contributing to nest building and care for the young.

The vocalizations of the Coppery-tailed Coucal are composed of deep, bubbling notes that resonate through its wetland habitats.

Breeding season for this species occurs from January to March. The Coppery-tailed Coucal is believed to be monogamous, with both parents involved in nesting activities. They construct a domed nest out of grasses, reed fragments, and twigs, lining it with leaves. Nesting may begin even before the structure is complete. The clutch typically consists of two to four eggs, which are incubated immediately after the first egg is laid. The eggs hatch at intervals, and both parents are diligent in caring for the young, feeding them on frogs and locusts. The fledglings leave the nest at about seventeen days old, sometimes before they are fully capable of flight.

The Coppery-tailed Coucal can be confused with the Senegal Coucal (Centropus senegalensis), but careful observation of the coppery sheen on the rump and the size of the bird can help distinguish between the two.

The diet of the Coppery-tailed Coucal is varied, including amphibians, fish, small birds, reptiles, rodents, grasshoppers, crabs, snails, and occasionally green plant material. It also displays opportunistic behavior by scavenging for dead fish and other edible detritus.

The Chacma baboon (Papio ursinus) is a member of the Old World monkey family. It is one of the largest of all monkeys. Located primarily in southern Africa, the chacma baboon has a wide variety of social behaviors, including a dominance hierarchy, collective foraging, adoption of young by females, and friendship pairings. In general, the species is not threatened, but hunting, trapping, and accidents kill or remove many baboons from the wild, thereby reducing their numbers and disrupting their social structure.

The Chacma baboon is perhaps the longest species of monkey and it is also one of the heaviest. Adult males can in some instances be about twice as long and three times as heavy as adult females. Perhaps the most distinctive feature of this baboon is its long, downward-sloping face. The Chacma baboon is generally dark brown to gray in color, with a patch of rough hair on the nape of its neck. Unlike the males of northern baboon species (Guinea, hamadryas, and Olive baboons), Chacma males do not have a mane. The three subspecies are differentiated by size and color. The Cape chacma is a large, heavy, dark-brown, and has black feet. The Gray-footed chacma is slightly smaller than the Cape chacma, lighter in color and build, and has gray feet. The Ruacana chacma generally appears to be a smaller, less darkly colored version of the Cape chacma.

15-4-2018 CHOBE RIVER, NAMIBIA - YELLOW BILLED STORK (Mycteria ibis) COURTESY OF MRS VALERIE FISHER

The Yellow-billed Stork, Mycteria ibis, is a striking wader of the African continent. This medium-sized stork, with a height ranging from 90 to 105 cm, is adorned with a predominantly white plumage contrasted by a short black tail with a green and purple sheen. Its namesake yellow bill is slightly curved at the end, distinguishing it from other storks.

During the breeding season, the Yellow-billed Stork's plumage is tinged pink on the upperwings and back, and its legs turn a vivid pink. The male is generally larger with a longer bill compared to the female. Juveniles can be identified by their greyish-brown coloration, dull yellowish bill, and brown legs.

This species favors wetlands, shallow lakes, and mudflats, typically in water depths of 10-40 cm, avoiding heavily forested areas and deep waters unsuitable for their feeding techniques.

The Yellow-billed Stork is found across Eastern Africa, from Senegal and Somalia to South Africa, and in parts of Madagascar. It exhibits local migratory movements influenced by rainfall patterns.

These storks are known for their high-stepped stalking gait and impressive flight aerobatics. They are generally non-vocal but may emit hissing screams during social displays in the breeding season.

The species is mostly silent, but during the breeding season, it engages in bill clattering and a distinctive "woofing" wing beat. Nestlings produce a loud, monotonous braying call to solicit food from adults.

Breeding is triggered by heavy rainfall and subsequent flooding, which increases prey availability. Courtship involves a series of displays and rituals leading to pair formation. Both parents share incubation duties, and hatching is asynchronous, leading to size disparities among chicks.

The Yellow-billed Stork can be confused with other storks, but its yellow bill and breeding plumage are distinctive.

The diet consists mainly of small fish, crustaceans, and other aquatic organisms. They feed by touch, using a snap-bill reflex to capture prey and a foot-stirring technique to flush out hidden prey.

The Yellow-billed Stork is classified as Least Concern due to its large range and population size, despite local threats such as habitat reduction and poaching.

15-4-2018 CHOBE RIVER, NAMIBIA - SOUTHERN GREATER KUDU (Tragelaphus Strepsiceros) COURTESY OF MRS VALERIE FISHER

The Greater kudu (Tragelaphus strepsiceros) is a woodland antelope found in Africa. Despite occupying such widespread territory, Greater kudus are sparsely populated in most areas due to declining habitat, deforestation, and poaching.

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 is usually darker in color than the rest of the body and exhibits a small white v-shaped mark that runs between the eyes. Bulls tend to be much larger than cows, and vocalize much more; they also have beards running along their throats and large horns with two and a half twists.

The range of 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 they occur are the Central African Republic, Chad, the Democratic Republic of the Congo, Djibouti, Malawi, Mozambique, Somalia, Swaziland, and Uganda. These antelopes live in mixed scrub woodlands 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.

15-4-2018 CHOBE RIVER, NAMIBIA - AFRICAN STONECHAT (Saxicola torquatus) COURTESY OF MRS VALERIE FISHER

The males have a black head, a white half-collar, a black back, a white rump, and a black tail; the wings are black with a large white patch on the top side of the inner wing. The upper breast is usually dark orange-red, with a sharp or gradual transition to white or pale orange on the lower breast and belly depending on subspecies. In a few, black replaces the orange breast feathers in part or entirely.

Females have brown rather than black above and on the head with an indistinct paler eyebrow line, chestnut-buff rather than orange below, and less white on the wings. Both sexes' plumage is somewhat duller and streakier outside the breeding season.

It has a scattered distribution across much of sub-Saharan Africa, occurring locally as far north as Senegal and Ethiopia. Outlying populations are found the mountains of southwest Arabia and on Madagascar and Grande Comore. It is non-migratory, moving only locally if at all. As a result, it has developed much regional variation, being divided into 13 subspecies.

15-4-2018 CHOBE RIVER, NAMIBIA - WOODLAND KINGFISHER (Burhinus vermiculatus) COURTESY OF MRS VALERIE FISHER

The Woodland Kingfisher, Halcyon senegalensis, presents a striking figure with its vivid blue plumage. This medium-sized kingfisher measures approximately 23 cm in length, with adults showcasing a bright blue back, wing panel, and tail. Its head, neck, and underparts are a pristine white, contrasted by black shoulders. The flight is characterized by rapid and direct movements. A notable feature is the large bill, with a red upper mandible and a black lower mandible, while the legs and feet are a dark grey hue.

When identifying the Woodland Kingfisher, look for the dark lores that create a distinct stripe through the eye, a feature that distinguishes it from the similar Mangrove Kingfisher, whose stripe does not extend through the eye. The underwing, primaries, and secondaries are black with white underwing coverts, and the inner webs of the base of the flight feathers are white, forming an indistinct white wingbar. The breast is white, and the sexes appear similar, though juveniles are less vibrant and possess a brown bill.
