20-4-2018 OKAVANGO DELTA, BOTSWANA - RATTLING CISTICOLA (Cisticola chiniana)

The Rattling Cisticola, Cisticola chiniana, is a small, sprightly bird belonging to the Cisticolidae family. It is a bird that is native to the diverse landscapes of Africa, south of the equator, and parts of East Africa.

This species is characterized by its streaked appearance and a distinctive rufous cap. When perched, one may notice its tail is typically held upright, and its flight is undulating, which aids in identification.

The Rattling Cisticola thrives in a variety of savanna and scrubland habitats, from arid to moist and upland regions. It has a particular affinity for environments dominated by thorn trees or shrubs, such as those of the genera Dichrostachys. It is also a common sight in miombo and mopane woodlands, as well as the Mozambican coastal plain.

This bird's range extends across a swath of the African continent, including Angola, Botswana, Burundi, Congo, DRC, Eswatini, Ethiopia, Kenya, Malawi, Mozambique, Namibia, Somalia, South Africa, South Sudan, Tanzania, Uganda, Zambia, and Zimbabwe.

The Rattling Cisticola is particularly conspicuous during the summer months, when it can be seen—or more often heard—delivering its strident calls from prominent perches atop trees or bushes.

Its call is a distinctive and repetitive sound that can be transcribed as "chee-chee chichi-chirrrrr," although there is some variation among individuals.

20-4-2018 OKAVANGO DELTA, BOTSWANA - PLAINS ZEBRA (Equus quagga)

The Plains zebra (Equus quagga, formerly Equus burchellii) is the most common and geographically widespread species of zebra. It is the most recognizable grazing animal on the African continent. Their closest relatives are donkeys and horses. The sparkling coat of zebras reflects more than 70% of incoming heat, which is likely to help them survive under the scorching African sun. Each of these animals has its own unique stripe pattern, which helps identify individuals. Additionally, the striped coat is used as ideal camouflage, allowing zebras to remain unspotted by predators in the grass.

The Plains zebra is dumpy bodied with relatively short legs and a skull with a convex forehead and a somewhat concave nose profile. The neck is thicker in males than in females. The ears are upright and have rounded tips. As with all wild equids, the Plains zebra has an erect mane along the neck and a tuft of hair at the end of the tail. It is boldly striped in black and white and no two individuals look exactly alike. Compared to other species, the Plains zebra has broader stripes. The stripes are vertical on the fore part of the body and tend towards the horizontal on the hindquarters. Northern zebra populations have narrower and more defined striping; southern populations have varied but lesser amounts of striping on the under parts, the legs, and the hindquarters. Southern populations also have brown "shadow" stripes between the black and white coloring. These are absent or poorly expressed in northern zebras. The natal coat of a foal is brown and white and the brown darkens with age.

20-4-2018 OKAVANGO DELTA, 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.

20-4-2018 OKAVANGO DELTA, BOTSWANA - LILAC BREASTED ROLLER (Coracias caudatus)

The lilac-breasted roller (Coracias caudatus) is a member of the roller family, Coraciidae, resplendent in a panoply of pastel hues. This African bird is a sight to behold, with its lilac throat and breast, olive crown to mantle, and cheeks of lilac-rufous. The species is further adorned with long, black tail streamers, which juveniles lack. Unofficially, it is considered the national bird of Kenya.

In the field, the lilac-breasted roller is almost unmistakable. Adults boast a lilac throat that deepens into a darker lilac breast, with an olive crown and mantle. The cheeks and ear coverts are a lilac-rufous. Juveniles and immatures can be identified by their lack of tail streamers and a throat and breast of rufous-tawny with broad diffuse buffy-white streaks. The species is not sexually dimorphic, though males may be slightly larger.

The lilac-breasted roller favors open woodland and savanna, typically avoiding treeless expanses. They are often seen perched high, surveying the landscape for prey.

This species is widely distributed across Southern and Eastern Africa and is a vagrant to the southern Arabian Peninsula. It is most abundant in Kenya and can be found from sea level to elevations of 2,000 meters or more.

Lilac-breasted rollers are usually solitary or found in pairs. They are known for their aggressive defense of their nests against raptors and other birds. During the breeding season, males perform acrobatic flights, swooping and diving while emitting harsh cries.

3-5-2018 PEGO MARJAL, ALICANTE - LITTLE EGRET (Egretta garzetta)

The Little Egret, Egretta garzetta, is a dainty heron adorned in pure white plumage. It is characterized by a slender black beak, long black legs, and, notably in the western race, yellow feet. This elegant bird is a sight to behold with its graceful neck and poised stance.

Adult Little Egrets measure between 55–65 cm in length with a wingspan of 88–106 cm, and weigh 350–550 g. Their plumage is predominantly white, though some may exhibit bluish-grey coloration. Breeding adults boast ornate nape plumes reaching about 150 mm, along with distinctive feathers on the breast and elongated scapulars. The bill and lores are black, with greenish-grey skin at the base of the lower mandible and around the eye, which houses a yellow iris. Legs are black with contrasting yellow feet, though juveniles may have greenish-black legs and duller feet. The subspecies E. g. nigripes is distinguished by yellow skin between the bill and eye, and blackish feet.

The Little Egret frequents a variety of wetland habitats, from the shores of lakes and rivers to marshes and coastal regions. It is often found in open environments, such as mangroves, swamps, mudflats, and sandy beaches, as well as human-altered landscapes like rice fields.

The species has a broad breeding distribution across warm temperate to tropical regions of Asia, Africa, Australia, and Europe. Northern populations are migratory, wintering in Africa and southern Asia, while others remain as permanent residents in warmer areas.

Little Egrets are social yet territorial when feeding. They exhibit a range of foraging behaviors, from active chasing to patient ambush. Their movements are often in response to the presence of other animals, which may stir up prey.

The Little Egret's vocalizations include croaking and bubbling sounds at breeding colonies and a harsh alarm call when disturbed. These calls are similar to those of the Black-crowned Night Heron and the Cattle Egret.

Breeding colonies are often mixed with other water birds. Nests are platforms of sticks located in trees, shrubs, or reed beds. Clutches typically consist of three to five bluish-green eggs, incubated by both parents for about three weeks. The young fledge at approximately six weeks old.

The diet is diverse, including fish, amphibians, small reptiles, mammals, birds, crustaceans, molluscs, insects, spiders, and worms. The Little Egret employs various hunting techniques, both in water and on land, to capture its prey.

The Little Egret is classified as "Least Concern" by the IUCN. Conservation measures in the 20th century have allowed populations to recover in Europe, and the species has been expanding its range. It is now successfully colonizing new areas, including the New World.

3-5-2018 PEGO MARJAL, ALICANTE - 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 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).

3-5-2018 VILLALONGA RESERVOIR, 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.

3-5-2018 PEGO MARJAL, ALICANTE - LITTLE RINGED PLOVER (Charadrius dubius)

The Little Ringed Plover, Charadrius dubius, presents itself as a small and sprightly bird. Its plumage is a subtle blend of grey-brown on the back and wings, while its underparts remain a crisp white. A distinctive black neckband adorns its white breast, complementing the brown cap atop its head. A striking black mask encircles the eyes, set against a white forehead, and is accentuated by a clear yellow eye-ring—a feature unique to this species. Its bill is short and dark, and the legs exhibit a flesh-coloured hue, with all toes connected by webbing.

To distinguish the Little Ringed Plover from its close relatives, one should note the colour of its legs, the pattern on its head, and the presence of the yellow eye-ring. These characteristics set it apart from the larger Ringed Plover, which lacks these specific traits.

The preferred breeding grounds of the Little Ringed Plover are open gravel areas adjacent to freshwater sources. These include gravel pits, river edges, and islands, where vegetation is sparse or non-existent.

This bird boasts a wide range across the Palearctic, extending to northwestern Africa. It is a migratory species, retreating to the warmer climates of Africa during the winter months.

The Little Ringed Plover is known for its foraging habits on muddy terrains, where it primarily relies on sight to locate its prey. It is a ground-nesting bird, with both males and females sharing the responsibility of incubating the eggs.

3-5-2018 PEGO MARJAL, ALICANTE - WOODCHAT SHRIKE (Lanius senator)

The Woodchat Shrike, Lanius senator, is a captivating bird, slightly larger than its cousin, the Red-backed Shrike. The male boasts a distinctive appearance with black and white upper parts and a rich chestnut crown, while the female and juveniles display a more subdued brown and white vermiculated plumage with buff underparts.

To identify the Woodchat Shrike, look for the male's striking black and white upper parts and chestnut crown. The female and young birds are less conspicuous with their vermiculated brown and white upper parts and buff underparts. The western Mediterranean race, L. s. badius, lacks the prominent white wing patches seen in other subspecies.

This species has a preference for open wooded areas with scattered trees, such as orchards, especially where the ground is bare or sandy.

The Woodchat Shrike breeds across southern Europe, the Middle East, and northwest Africa, and migrates to winter in tropical Africa. Its range spans from Portugal to Greece and from Mauritania to Libya, with occasional sightings as far north as Great Britain.

The Woodchat Shrike is known for its perching behaviour, often seen on exposed lookouts from where it swoops down or glides to capture its prey. It is also known to occasionally impale its prey on thorns, a behaviour typical of shrikes.

Breeding occurs from early May to mid-July. Both sexes contribute to nest building, which is typically situated in a tree. The clutch consists of 5-6 eggs, incubated mainly by the female, with fledglings cared for by both parents.

The diet of the Woodchat Shrike is primarily insectivorous, with beetles being a favoured choice. It employs a sit-and-wait hunting strategy from elevated perches and is known to dismember larger insects.

The Woodchat Shrike is currently classified as Near Threatened due to long-term population declines attributed to habitat loss, pesticide use, climate change, hunting during migration, and other factors. Despite this, it has a large estimated population of 5.9-10 million individuals.

3-5-2018 PEGO MARJAL, ALICANTE - COMMON CHIFFCHAFF (Phylloscopus collybita)

The Common Chiffchaff, Phylloscopus collybita, is a diminutive and sprightly leaf warbler known for its distinctive, onomatopoeic song. This small, migratory passerine is characterized by its greenish-brown upperparts and off-white underparts, with a weight ranging from 6 to 8 grams and a length of 10-12 centimeters.

In the field, look for the Common Chiffchaff's short whitish supercilium, fine dark bill, and dark legs. Its primary projection is short, and the plumage may appear duller and browner as it wears. Juveniles are browner above with yellow-white underparts, but they soon acquire brighter plumage after their first moult.

The Common Chiffchaff breeds in open woodlands with a mix of taller trees and ground cover across northern and temperate Europe, Asia, and parts of north Africa. It prefers woodland with trees at least 5 meters high and an undergrowth of grasses and nettles.

This species has a vast breeding range, extending from Europe to eastern Siberia and northward to about 70 N. It winters in southern and western Europe, southern Asia, and north Africa. The Common Chiffchaff is one of the earliest spring migrants to return to its breeding grounds and one of the last to depart in autumn.

1-5-2018 MONTE CORONA, VALENCIA - HOUSE SPARROW (MALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.

Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

The house sparrow is highly adaptable and can thrive in both urban and rural environments. It is commonly found in close association with human habitation and avoids dense forests, grasslands, polar regions, and deserts far from human development.

22-4-2018 OKAVANGO DELTA, BOTSWANA - GREATER KUDU (FEMALE) (Tragelaphus Strepsiceros)

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.

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.

Greater kudus are social animals that live in groups within their home areas. Females usually form small groups of 6-10 with their offspring, but sometimes they can form a herd of up to 20 individuals. Male kudus may form small bachelor groups, but they are more commonly found as solitary and widely dispersed individuals. Solitary males will join the group of females and calves only during the mating season. Home ranges of maternal herds can overlap with other maternal herds while home ranges of adult males generally encompass the ranges of two or three female groups. Greater kudus may be active throughout the 24-hour day. During the day, they normally cease to be active and instead seek cover under woodland, especially during hot days. They feed and drink in the early morning and late afternoon, acquiring water from waterholes or roots and bulbs that have high water content. When a herd is threatened by predators, an adult (usually female) will issue a bark to alert the rest of the herd. Greater kudus communicate using many other vocalizations, including low grunts, clucks, humming, and gasping.

20-4-2018 OKAVANGO DELTA, BOTSWANA - HIPPOPOTAMUS (Hippopotamus amphibius)

The hippopotamus (Hippopotamus amphibius) (/ˌhɪpəˈpɒtəməs/; pl.: hippopotamuses; often shortened to hippo (pl.: hippos), further qualified as the common hippopotamus, Nile hippopotamus and river hippopotamus, is a large semiaquatic mammal native to sub-Saharan Africa. It is one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus (Choeropsis liberiensis or Hexaprotodon liberiensis). Its name comes from the ancient Greek for "river horse" (ἱπποπόταμος).

After elephants and rhinoceroses, the hippopotamus is the next largest land mammal. It is also the largest extant land artiodactyl. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamids are cetaceans (whales, dolphins, porpoises, etc.), from which they diverged about 55 million years ago. Hippos are recognisable for their barrel-shaped torsos, wide-opening mouths with large canine tusks, nearly hairless bodies, pillar-like legs, and large size: adults average 1,500 kg (3,300 lb) for bulls (males) and 1,300 kg (2,900 lb) for cows (females).

Hippos inhabit rivers, lakes, and mangrove swamps. Territorial bulls each preside over a stretch of water and a group of five to thirty cows and calves. Mating and birth both occur in the water. During the day, hippos remain cool by staying in water or mud, emerging at dusk to graze on grasses. While hippos rest near each other in the water, grazing is a solitary activity and hippos typically do not display territorial behaviour on land. Hippos are among the most dangerous animals in the world due to their aggressive and unpredictable nature. 

They are threatened by habitat loss and poaching for their meat and ivory (canine teeth).

20-4-2018 OKAVANGO DELTA, BOTSWANA - HAMERKOP (Scopus umbretta)

The hamerkop is mostly silent when alone, but is fairly vocal when in pairs or in groups. The only call it usually makes when alone is a flight-call, a shrill “nyip” or “kek”. In groups, vocalisations include a range of calls including cackles and nasal rattles. One highly social call is the "yip-purr" call. This call is only made in a social context, when at least three birds, but up to 20 are gathered in a flock. Birds start by giving a number of "yip" calls, eventually giving way to purring notes. This call is made with the neck extended and sometimes accompanied by wing flapping, and becomes more vigorous when larger numbers of birds are present.

Another common social behaviour is "false mounting", in which one bird stands on top of another and appears to mount it, but they do not copulate. This behaviour has been noted between both mated pairs and unmated birds, and even between members of the same sex and in reversed mountings, where females mount males. Because of this, the behaviour is thought to be social and not related to the pair bond. Dominant birds may signal to subordinates by opening their bills slightly and erecting their crests, but the species is not very aggressive in general towards others of its species. Birds in groups also engage in social allopreening when in groups. One bird presents its face of back of the head to the other to be preened.

This species normally feeds alone or in pairs, but also feeds in large flocks sometimes. It is a generalist, although amphibians and fish form the larger part of its diet. The diet also includes shrimp, insects, and rodents. The type of food they take seems to vary by location, with clawed frogs and tadpoles being important parts of the diet in East and Southern Africa and small fish being almost the only prey taken in Mali. Because it is willing to take a wide range of food items and also take very small prey, it is not resource-limited and only feeds for part of the day.

The usual method of hunting is to walk in shallow water looking for prey. Prey is located differently depending on circumstances; if the water is clear, it may hunt by sight, but if the water is very muddy, it probes its open bill into water or mud and shuts it. It may shuffle one foot at a time on the bottom or suddenly open its wings to flush prey out of hiding. Prey caught in mud is shaken before swallowing to clean it, or if available, taken to clearer water to do so. The species also feeds while in flight. A bird flies slowly low over the water with legs dangling and head looking down, then dipping feet down and hovering momentarily when prey is sighted. The prey is then snatched with the bill and swallowed in flight. This method of hunting can be very successful, with one birds catching prey on 27 of 33 attempts during one 45-minute session. It is also opportunistic, and feeds on swarming termites when they conduct their nuptial flights, snatching as many as 47 alates (flying termites) in five minutes.

This species has been recorded foraging for insects flushed by grazing cattle and buffalo, in a manner similar cattle egrets, and has been observed fishing off the backs of hippopotamuses.It has also been recorded feeding in association with banded mongooses; when a band of mongooses began hunting frogs in dried mud at the side of a pool of water a pair of hamerkops attended the feeding group, catching frogs that escaped the mongooses.

The strangest aspect of hamerkop behaviour is the huge nest, sometimes more than 1.5 m (4 ft 11 in) across, and strong enough to support a man's weight. When possible, it is built in the fork of a tree, often over water, but if necessary, it is built on a bank, a cliff, a human-built wall or dam, or on the ground. A pair starts by making a platform of sticks held together with mud, then builds walls and a domed roof. A mud-plastered entrance 13–18 cm (5.1–7.1 in) wide in the bottom leads through a tunnel up to 60 cm (24 in) long to a nesting chamber big enough for the parents and young. Nests have been recorded to take between 10 and 14 weeks to build, and one researcher estimated that they would require around 8,000 sticks or bunches of grass to complete. Nesting material may still be added by the pair after the nest has been completed and eggs have been laid. Much of the nesting material added after completion is not sticks, but an odd collection of random items including bones, hide, and human waste.

Pairs of hamerkop are compulsive nest builders, constructing three to five nests per year whether they are breeding or not.[25] Both members of the pair build the nest, and the building of nests may have a function in creating or maintaining the pair bond between them. Barn owls and eagle owls may force them out and take over the nests, but when the owls leave, the pair may reuse the nest. Owls may also use abandoned nests, as may snakes, small mammals such as genets, and various birds, and weaver birds, starlings, and pigeons may attach their nests to the outside. A few reports exist of hamerkops nesting close together, including in Uganda, where 639 nests were seen in an area of 8 km2 (3.1 sq mi); even if each pair had made seven nests, this would mean 80 pairs were nesting in that area. The species is not treated as colonial, as it does not habitually nest close together, but is not thought to be highly territorial, either. Even where pairs have home ranges that are more spread out those home ranges overlap and are the boundaries are poorly defined.

Breeding happens year-round in East Africa, and in the rest of its range, it peaks at different times, with a slight bias towards the dry season. Pairs engage in a breeding display, then copulate on the nest or on the ground nearby. The clutch consists of three to seven eggs which start chalky white, but soon become stained.[10] The eggs measure 44.5 mm × 33.9 mm (1.75 in × 1.33 in) on average, and weight around 27.8 g (0.98 oz), but considerable variation is seen. Egg size varies by season, by the overall size of the clutch, and from bird to bird. Both sexes incubate the eggs, but the female seems to do the most of the work. Incubation takes around 30 days from the first egg being laid to hatching, eggs are laid with intervals of one to three days, and they hatch asynchronously.

Both parents feed the young, often leaving them alone for long times. This habit, which is unusual for wading birds, may be made possible because of the thick nest walls. The young hatch covered with grey down. By 17 days after hatching, their head and crest plumage is developed, and in a month, their body plumage. They first leave the nest around 44 to 50 days after hatching, but continue to use the nest for roosting at night until they are two months old.

It is known in some cultures as the lightning bird, and the Kalahari Bushmen believe or believed that being hit by lightning resulted from trying to rob a hamerkop's nest. They also believe that the inimical god Khauna would not like anyone to kill a hamerkop. According to an old Malagasy belief, anyone who destroys its nest will get leprosy, and a Malagasy poem calls it an "evil bird". Such beliefs have given the bird some protection. A south African name Njaka meaning "rain doctor" is derived from its habit of calling loudly prior to rain.

Scopus, a database of abstracts and citations for scholarly journal articles, received its name in honour of this bird, as did the journal of the East African Natural History Society, Scopus.

20-4-2018 OKAVANGO DELTA, 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.

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.

Crested barbets are typically observed alone or in pairs. They exhibit a preference for foraging on the ground but are also known to vocalize from exposed branches. Their flight is limited and typically consists of short bursts. These birds roost in tree cavities and are highly territorial, often aggressively defending their space against other birds and even larger threats like rats and snakes.

The male crested barbet is renowned for its continuous trill, a call that can persist for extended durations, serving as a vocal beacon within its habitat.

Crested barbets are monogamous and territorial during the breeding season. They nest in tree holes or logs, with territory size varying by habitat. Their breeding season spans from September to December, during which they may lay one to five eggs at daily intervals. Incubation, primarily by the female, lasts between 13 and 17 days starting from the second or third egg. The hatchlings are altricial, being naked and blind at birth, and are fed insects by both parents. After about 31 days, the fledglings leave the nest, and up to five broods may be raised in a single season.

The crested barbet's diet is omnivorous, consisting of insects, other birds' eggs, fruits, and occasionally small mammals like mice.

22-4-2018 OKAVANGO DELTA, BOTSWANA - SOUTHERN AFRICAN GIRAFFE (Giraffa giraffa ssp. giraffa),

The South African giraffe or Cape giraffe (Giraffa giraffa or Giraffa camelopardalis giraffa) is a species or subspecies of giraffe found in South Africa, Namibia, Botswana, Zimbabwe, Eswatini and Mozambique. It has rounded or blotched spots, some with star-like extensions on a light tan background, running down to the hooves.

In 2016, the population was estimated at 31,500 individuals in the wild.

The IUCN currently recognizes only one species of giraffe with nine subspecies. The Cape giraffe, along with the whole species, were first known by the binomen Camelopardalis giraffa as described by German naturalist Johann Christian Daniel von Schreber in his publication Die Säugethiere in Abbildungen nach der Natur mit Beschreibungen (The Mammals Illustrated from Nature with Descriptions) during his travel in the Cape of Good Hope in 1784. Dutch naturalist Pieter Boddaert also described it under the binomial name Giraffa giraffa whilst also identifying the nominate specimen of said species under the ternary name Giraffa camelopardalis giraffa in 1785.

The South African giraffe has dark, somewhat rounded patches "with some fine projections" on a tawny background colour. The spots extend down the legs and get smaller. The median lump of males is less developed.

The South African giraffe is found in northern South Africa, southern Botswana, southern Zimbabwe, and south-western Mozambique. After local extinctions in various places, South African giraffes have been reintroduced in many parts of Southern Africa, including in Eswatini. They are common in both in and outside of protected areas. South African giraffes usually live in savannahs and woodlands where food plants are available. Giraffes are herbivorous. They feed on leaves, flowers, fruits and shoots of woody plants such as Acacia.

South African giraffes live in a fission–fusion society system based on factors such as sex, age, season, and kinship. This allows them to adapt to environmental changes.

At present[when?], the South African giraffe population is estimated at 37,000 individuals, showing an increase of over 150% over the past three decades. The International Union for the Conservation of Nature, the body that administers the world's official endangered species list, announced in 2016 that it was moving the giraffe from a species of Least Concern to Vulnerable status in its Red List of Threatened Species report. That means the animal faces extinction in the wild in the medium-term future if nothing is done to minimize the threats to its life or habitat.

South African giraffes are uncommon in captivity. As of 2010, there are around 45 South African giraffes breeding in zoos. Approximately 12,000 privately owned farms, ranches, and national parks maintain populations of this giraffe.

22-4-2018 OKAVANGO DELTA, BOTSWANA - BLACK COLLARED BARBET ( Lybius corquatus)

The Black-collared Barbet, Lybius torquatus, is a plump and vividly marked bird, native to the diverse landscapes of sub-Saharan Africa. It is easily recognized by its robust size, typically ranging from 20 to 25 centimeters in length, and its large head adorned with a heavy, bristle-fringed bill characteristic of its genus. The species is named for its striking black collar and head, which contrast with the fiery red plumage surrounding its eyes and beak. Notably, the Black-collared Barbet exhibits morphological variability, with some individuals replacing the red head with a black one. Despite this variation, the species is sexually monomorphic, showing no discernible difference between males and females in either morphology or behavior.

When identifying the Black-collared Barbet, look for the distinctive black collar and head, as well as the intense red coloration around the eyes and beak. The bird's larger size sets it apart from other barbets. Its plumage may vary, with some individuals displaying a black head instead of the typical red. Both sexes appear identical, making sex differentiation in the field a challenge.

The Black-collared Barbet thrives in a variety of habitats across sub-Saharan Africa, including woodlands and savannas, where it can be found inspecting trees and utilizing nest holes for roosting.

This species has a wide range across sub-Saharan Africa, from Angola to Kenya, and southward to South Africa, encompassing countries such as Botswana, Burundi, the Democratic Republic of the Congo, Eswatini, Lesotho, Malawi, Mozambique, Namibia, Rwanda, Tanzania, Uganda, Zambia, and Zimbabwe.

The Black-collared Barbet is a gregarious bird, often seen acting in unison with others of its kind to repel intruders. They are known to roost together in groups, sometimes numbering up to 15 individuals in a single nest hole. Their flight is characterized by a direct path and a loud whirring of wings.

The vocal repertoire of the Black-collared Barbet is dominated by its antiphonal duets, often described as "too-puddly" or "too-doodle" calls. These duets are synchronized, with one bird singing a note followed by its partner, creating a seamless auditory experience. The birds engage in a greeting ceremony that includes wing-flicking and bowing to each other. In addition to its duets, the barbet produces a variety of calls, including a snarling warning and a loud buzzing.

The breeding season for the Black-collared Barbet occurs from December to February, during which time they may engage in more elaborate wing and flight displays as part of their mating rituals.

20-4-2018 OKAVANGO DELTA, BOTSWANA - BENNETT'S WOODPECKER (Campethera bennettii)

The Bennett's woodpecker, a species of bird in the Picidae family, is a striking figure in the woodlands and bushes of Africa. This bird, approximately 24 cm in length and weighing between 61 to 84 grams, is adorned with a palette of colors that include brown, yellow, white, and pale yellow. The male is particularly distinctive with its red forehead, crown, and nape, while the female sports a black forehead with white spots and brown or blackish-brown ear coverts and throat.

To identify the Bennett's woodpecker, look for the male's vibrant red head and the female's spotted black forehead. Both sexes have red eyes, a grey beak, and legs that are either bluish-green or grey-green. The underparts are pale yellow with dark spots on the breast and flanks. Juveniles have a black forehead and crown with darker upperparts. The subspecies C. b. capricorni is slightly larger with deeper colored underparts and fewer spots.

Bennett's woodpecker favors woodlands and bushes, including miombo, Baikiaea, Acacia, and mopane woodlands, which provide ample foraging opportunities and nesting sites.

This woodpecker has a patchy distribution across Angola, Botswana, Burundi, Democratic Republic of the Congo, Eswatini, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Zambia, and Zimbabwe.

Bennett's woodpecker can be observed singly, in pairs, or in family groups. It is known to forage primarily on the ground, in areas either bare or with short grass, and also within the branches of trees.

The vocal repertoire of this species includes "chuur" notes, a series of "wi-wi-wi-wi," "kee-kee-kee," or "ddrahh, ddrahh, ddray-ay, ddray-ay," and a chattering "wirrit-wirrit."

Breeding season for Bennett's woodpecker spans from August to February. They either excavate new holes or reuse old ones in trees for nesting. A clutch typically consists of three eggs, which are incubated for a period of 15 to 18 days.

The diet of Bennett's woodpecker is predominantly composed of ants and termites, including their eggs, which it skillfully extracts from the ground or tree bark.
