19-4-2018 CHOBE NATIONAL PARK, BOTSWANA - WHITE HEADED VULTURE (Trigonoceps occipitalis)

The White-headed Vulture, Trigonoceps occipitalis, presents a striking figure in the African skies. This medium-sized vulture, measuring 72–85 centimeters in length with a wingspan of 207–230 centimeters, is notable for its distinctive plumage. The females, slightly larger than the males, weigh an average of 4.7 kilograms, while the males tip the scales at less than 4 kilograms. The species exhibits reversed sexual dimorphism, a unique trait among its African counterparts.

This vulture is easily recognized by its contrasting black and white plumage. A white crest adorns its head, and the featherless regions of its face are a pale hue. Its beak is tinged pink, and the dark brown upper parts complement the black tail feathers. From below, the white feathers on its lower parts and legs are unmistakable. Each individual can be identified by a unique pattern in their median wing coverts.

The White-headed Vulture is adapted to mixed, dry woodlands at lower altitudes, avoiding human settlements. It thrives in thorny Acacia-dominated landscapes and can be found at elevations up to 4,000 meters in Ethiopia and around 3,000 meters in Kenya.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - AFRICAN SACRED IBIS (Threskiornis aethiopicus ssp. aethiopicus)

The African sacred ibis (Threskiornis aethiopicus) is a striking wading bird from the family Threskiornithidae. It is characterized by its all-white plumage, save for the dark plumes on its rump. The adult bird measures approximately 68 cm (27 in) in length, with a wingspan ranging from 112 to 124 cm (44 to 49 in), and weighs between 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females. The species is distinguished by its bald head and neck, thick curved bill, and black legs. In flight, the white wings reveal a contrasting black rear border. The eyes are brown, encircled by a dark red orbital ring.

When identifying the African sacred ibis, look for the combination of its white body, black head, neck, and bill. Juveniles can be recognized by their less pristine white plumage, smaller bill, and some feathering on the neck. The presence of greenish-brown scapulars and more black on the primary coverts also helps to distinguish younger birds.

This ibis favors marshy wetlands and mud flats, both inland and along the coast. It is often found nesting in trees near water and is known to frequent very shallow wetlands, wet pastures with soft soil, cultivation areas, and rubbish dumps.

The African sacred ibis is indigenous to Sub-Saharan Africa and parts of the Middle East, including small regions of Iraq, Iran, and Kuwait. The species has migratory populations that move with the rains, with some South African birds traveling as far north as Zambia, while those north of the equator migrate in the opposite direction.

The species has been introduced to various parts of Europe, including Italy, France, and the Netherlands, as well as to Florida, Taiwan, and the United Arab Emirates. In Europe, it is considered an invasive species.

The African sacred ibis is a social bird, often seen in flocks. It is predominantly silent, but can occasionally emit puppy-like yelping sounds. The species is known for its predatory feeding habits, which occur mainly during the day.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - RED BACKED SHRIKE (Lanius collurio)

The red-backed shrike (Lanius collurio) is a carnivorous passerine bird and member of the shrike family, Laniidae. Its breeding range stretches from Western Europe east to central Russia. It is migratory and winters in the eastern areas of tropical Africa and southern Africa.

20-4-2018 OKAVANGO DELTA, BOTSWANA - VERVET MONKEY (Chlorocebus pygerythrus)

The Vervet monkey (Chlorocebus pygerythrus) is an Old World monkey native to Africa. The term "vervet" is also used to refer to all the members of the genus Chlorocebus. These adorable monkeys live in social groups and involve their communication and alarm calls, specifically in regard to kin and group recognition, and particular predator sightings.

The Vervet monkey is of medium to large size and has a black-tipped tail which is often longer than its body. Its fur is olive or gray, lighter on the underside. Its hands and feet are black, as are its ears and face. Its face has a white band above it, framed with white cheek tufts. Its arms and legs are long, about the same length as each other, to enable the monkey to walk with ease on all fours while on the ground, and this actually makes it quite speedy when running. The males tend to be bigger than the females.

Vervet monkeys live south of the Sahara and across Eastern Africa. They are also found in western and southern Africa from Ghana to Uganda. They inhabit savanna, forests, and woodlands that tend to be near water; their favorite spot is acacia forests lining rivers and lakes.

Vervets are arboreal monkeys, spending most of their time in the trees where they feel safe. Although these monkeys do venture to the ground looking for food and water, they rarely go far from the trees, which serve as protection from predators. These animals are diurnal and spend their days foraging, and then rest at night. They are very sociable animals, forming troops of between 10 and 50. The troops are made up of adult females with their young, while males wander between different troops both to socialize and mate. Females remain in their groups throughout life. Separate dominance hierarchies are found for each sex. Male hierarchies are determined by age, tenure in the group, fighting abilities, and allies, while female hierarchies are dependent on maternal social status. A large proportion of interactions occurs between individuals that are similarly ranked and closely related. Vervet monkeys have four confirmed predators: leopards, eagles, pythons, and baboons. The sighting of each predator elicits an acoustically distinct alarm call. As infants, vervets learn to make a variety of calls from observation alone, without explicit tutelage. Vervet monkeys are thought to have up to 30 different alarm calls. In the wild, they have been seen giving a different call when seeing a human being approaching. Mothers can recognize their offspring by a scream alone.

Vervet monkeys are omnivorous and consume plant matter as well as other animals. Young shoots and leaves comprise most of their diet, as well as tree bark, fruits and flowers, and fruits from the surrounding trees. On the ground, they forage for roots, bulbs, grasses, and seeds, and sometimes supplement their diet with, eggs, rodents, insects, birds, and various small animals.

Vervet monkeys are polygynous, with females typically having few mates during their lifetime, while some males will have numerous mates. From about five years old they are able to reproduce. The mating season is between April and June. The gestation period is about five and a half months, and a single infant is born, whereupon it is cleaned by the mother. The baby clings to the mother’s stomach for about the first week. Vervet monkey babies soon develop strong social connections with other monkeys and begin to interact and play with them by as young as a month old. They suckle until nearly 4 months of age when they begin eating softer vegetation but are not weaned fully until about a year old.

20-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LION (FEMALE) (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.

The lion is a generalist hypercarnivore and is considered to be both an apex and keystone predator due to its wide prey spectrum. Its prey consists mainly of medium-sized to large ungulates, particularly blue wildebeest, plains zebra, African buffalo, gemsbok and giraffe. It also frequently takes common warthog despite it being much smaller. In India, chital and sambar deer are the most common wild prey, while livestock contributes significantly to lion kills outside protected areas. It usually avoids fully grown adult elephants, rhinoceros and hippopotamus and small prey like dik-dik, hyraxes, hares and monkeys. Unusual prey include porcupines and small reptiles. Lions kill other predators but seldom consume them.

21-4-2018 OKAVANGO DELTA, BOTSWANA - RED BILLED BUFFALO WEAVER (Bubalornis niger)

The Red-billed Buffalo Weaver (Bubalornis niger) is a robust bird, the largest within the Ploceidae family, with males averaging a body mass of 82.1 grams and females slightly lighter at 70.7 grams. The species exhibits a modest sexual dimorphism; males are adorned with dark chocolate brown plumage, accented with white flecks on the wing edges and tips, and a distinctive red bill. Females share the same rich brown coloration but lack the white wing markings and feature broad white hems on their chin and throat feathers. Juveniles present a paler brown hue as they mature.

To identify the Red-billed Buffalo Weaver, look for its red bill, which sets it apart from its cousin, the White-billed Buffalo Weaver. The male's red bill contrasts with his dark plumage and reddish-brown feet, while the female's lighter brown legs and white throat markings are key distinguishing features.

This species thrives in the dry savannas and sparse woodlands, often in areas influenced by human activity and grazing livestock.

The Red-billed Buffalo Weaver is found across eastern and southern Africa, where it has adapted well to environments altered by humans.

These birds are social, living in colonies, and can be seen in small family units or large flocks. Males are polygamous, with a hierarchy where dominant males control more nest chambers and females. Aggressive displays and loud calls are used for defense, while some males may cooperate in nest building and chick rearing.

The Red-billed Buffalo Weaver's vocalizations are part of its social behavior, used by males to assert dominance and defend their territory.

Breeding takes place in colonies within large, communal nests made of thorny twigs, divided into lodges with multiple chambers. Females, sometimes with male assistance, construct smaller nests within these chambers using grass, leaves, and roots. The breeding season peaks from December to March, with females laying 2 to 4 eggs and incubating them for about 14 days. Chicks fledge after 20 to 23 days.

30-4-2018 MONTE CORONA, VALENCIA - WAVE MOTH (Idaea cervantaria)

Idaea cervantaria is a species of insects with 1239 observations

Wingspan 1.4 to 2.2 cm. Straw-like in appearance, with yellowish wings with scattered dark, brown or grayish scales. On each wing it has a wavy line with small pointed dots, pointing backwards. Sometimes these details are not noticeable. Between these lines and the rear edge, it has dark spots that may have a  light wavy stripe. It has a point on each wing but the ones on the front can go unnoticed.

There are other similar species that are impossible to distinguish externally, so for correct and secure identification it is necessary to resort to genital analysis. Several of them have been found in the province of Malaga, although I. cervantaria is currently the most common and the only one that has been observed in urban environments.

In the province of Malaga, individuals determined by genital analysis were found in January, February and May, while those suspected of being so can be found in all months of the year.

1.4 to 2.2 cm wingspan. Straw-coloured, with yellowish wings with scattered dark, brown or greyish scales. On each wing it has a wavy line with small pointed spots, pointing backwards. Sometimes these details are barely noticeable. Between these lines and the rear edge, it has dark spots that may have a  light wavy stripe. It has a spot on each wing but those on the front wings may go unnoticed.

There are other similar species that are impossible to distinguish externally, so for a correct and safe identification, genital analysis must be used. Several of them have been found in the province of Malaga, although I. cervantaria is currently the most common and the only one that has been observed in urban environments.

The caterpillars feed on dry leaves of herbaceous plants and in captivity on petals of different Asteraceae and sea alder (Lobularia maritima), the latter common in our province, especially in sunny areas of the limestone mountains, and occasionally used in gardening for the showiness of its inflorescences.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - COMMON IMPALA (FEMALE) (Aepyceros melampus ssp. melampus)

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.

Impalas are distributed throughout the northeastern part of South Africa, Angola, southern Rwanda, Uganda, and Kenya. Close proximity to a water source is an important life condition for these animals. Generally, they prefer woodland with little undergrowth as well as low to medium-height grassland.

Impalas have polygynous mating system, where each male mates with a number of females. The period of peak breeding activity is March-May. During this period, pregnant females live in isolation to give birth. The gestation period lasts from 194 to 200 days, yielding a single calf, which weighs about 5kgs (11 lbs). After a few days, the calf and the female rejoin the herd. Then, after a while, the calf joins a crèche of other young impalas. They are weaned at 4-5 months old. Male impalas reach reproductive maturity at 1 year of age, while females are ready to breed when they are between 1 and 2 years old. Becoming reproductively mature, they, however, do not rush to establish territories. They typically start mating only at 4 years old.

These antelopes are both diurnal and nocturnal. They are most active just after sunrise and before sunset, socializing and moving with their herd, whereas, during the nighttime hours, impalas usually lie down and ruminate. Female impalas and their offspring gather into herds, containing from 15 to 100 individuals. The home range of each herd covers a territory, varying from 80 to 180 hectares. During the wet season, females become highly territorial, defending home ranges of their herds. On the other hand, young males form bachelor, non-territorial herds of up to 30 individuals. During the dry season, male and female herds can often be seen mixed together. Home ranges of mature breeding males vary from season to season. Thus, during the breeding season, they usually have smaller home ranges, which they fiercely defend. Males use a wide variety of methods to defend their home range, including fighting, tail-raising, chasing, roaring, erect posture as well as forehead marking and forehead rubbing.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - GREY GO AWAY BIRD (Corythaixoides concolor)

The grey go-away-bird, also known as the grey lourie, grey loerie, or kwêvoël, is a distinctive bird of the southern Afrotropics. With a smoky-grey plumage, a long tail, and a wispy crest that can be raised in excitement, this bird is a sight to behold. The strong, decurved beak is black, contrasting with the pink gape and tongue, and the plumage varies slightly in shade across different parts of the body.

Adults of both sexes are similar in appearance, measuring 47–51 cm from bill to tail tip and weighing between 200 to 300 grams. The crest, reaching 6 to 7 cm in length, is a key feature for identification. The darkest grey can be found on the chin and throat, while the area around the eyes and belly is paler. The breast plumage may have a slight olive wash, reminiscent of its relative, the bare-faced go-away-bird.

The grey go-away-bird is found in arid to moist, open savanna woodlands, particularly where Acacia trees abound. It is also a common sight in miombo woodlands, along watercourses, dry riparian forests, and in Acacia woodlands on alluvium. These birds are also comfortable in human-altered landscapes such as farms, gardens, and parks.

This species is native to a range of southern African countries, including Angola, the Democratic Republic of the Congo, Zambia, Tanzania, Malawi, Mozambique, Namibia, Botswana, Zimbabwe, South Africa, and Eswatini.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - FORK TAILED DRONGO (Dicrurus adsimilis)

The fork-tailed drongo, also known as the common drongo or African drongo, is a member of the Dicruridae family. It is a small bird with a distinctive fork-shaped tail, red-brownish eyes, and an entirely black plumage that exhibits a blue-green iridescence in certain lights. Both sexes are similar in appearance, with the underside of the bird being uniformly black, contrasting with the glossy black-blue upper body.

When identifying the fork-tailed drongo, look for its robust black beak, red eyes, and the deeply forked black tail. Juveniles can be distinguished by their dark brown tone, less pronounced tail fork, and lack of glossy shine on the lower body. During flight, the darker remiges of the D. a. adsimilis subspecies are particularly noticeable.

The fork-tailed drongo inhabits wooded habitats, including woodlands and savannas, and is tolerant of arid climates. It can be found at elevations up to 2200 meters.

This species is widespread across Africa south of the Sahara, with four recognized subspecies varying in range and physical characteristics. It was once thought to range into Asia, but the Asian species is now classified as the black drongo (D. macrocercus).

The fork-tailed drongo is known for its aggressive and fearless nature, often attacking larger animals to protect its nest. It is also a skilled kleptoparasite, using deceptive mimicry of other birds' alarm calls to steal food. These birds are solitary hunters and spend a significant portion of their day feeding.

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.

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. During the breeding season, it adorns itself with elegant long plumes that grace its crown and nape, adding to its mystique.

To identify the black heron, look for its distinctive black coloration and yellow feet. The bird stands between 42.5 to 66 cm tall and weighs approximately 0.27 to 0.39 kg. The breeding plumage, with its extended plumes on the head and neck, is particularly noteworthy.

The black heron is partial to shallow open waters, where it can be found along the edges of freshwater lakes and ponds. Its habitat also extends to marshes, riverbanks, rice fields, and seasonally flooded grasslands. In coastal regions, it frequents tidal rivers, creeks, alkaline lakes, and tidal flats.

This species is patchily distributed throughout Sub-Saharan Africa, from Senegal and Sudan down to South Africa, with a strong presence on the eastern half of the continent and in Madagascar. There have been occasional sightings in Greece and Italy.

The black heron is renowned for its unique hunting method known as canopy feeding, where it creates a shade with its wings to lure fish—a behavior that has captivated audiences in documentaries. It can feed solitarily or in groups, sometimes amassing in numbers up to 200. These herons are diurnal feeders with a preference for dusk and roost communally at night. Coastal flocks are known to roost at high tide.

Adept at fishing, the black heron's diet primarily consists of small fish, but it will also consume aquatic insects, crustaceans, and amphibians to satisfy its nutritional needs.

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.
