This sparrow favors savanna and woodland areas, where it can be seen flitting about in search of sustenance or engaging in social activities with its kin.

The Southern grey-headed sparrow is found across a swath of the African continent, from Angola and Zambia, stretching southwards into South Africa. Here, it has been expanding its range, becoming a more familiar sight in suitable habitats.

In its natural environment, the Southern grey-headed sparrow exhibits typical sparrow behaviors such as social flocking and active foraging. It is also known to be kept as a caged bird, much like its relative, the white-rumped seedeater.

BirdLife International has assessed the Southern grey-headed sparrow as being of Least Concern. This status indicates that, currently, there are no immediate threats to the population levels of this species, allowing bird enthusiasts to breathe a sigh of relief for the time being.

The Southern grey-headed sparrow, with its unassuming appearance and adaptable nature, continues to thrive in the African wilderness, much to the delight of birdwatchers and ornithologists alike.

14-4-2018 CHOBE RIVER, NAMIBIA - NILE CROCODILE (Crocodylus niloticus)

The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. It is widely distributed in sub-Saharan Africa, occurring mostly in the eastern, southern, and central regions of the continent, and lives in different types of aquatic environments such as lakes, rivers, swamps and marshlands. It occasionally inhabits deltas, brackish lakes and rarely also saltwater. Its range once stretched from the Nile Delta throughout the Nile River. Lake Turkana in Kenya has one of the largest undisturbed Nile crocodile populations.

Generally, the adult male Nile crocodile is between 3.5 and 5 m (11 ft 6 in and 16 ft 5 in) in length and weighs 225 to 750 kg (496 to 1,653 lb).[5][6] However, specimens exceeding 6.1 m (20 ft) in length and 1,000 kg (2,200 lb) in weight have been recorded. It is the largest predator in Africa, and may be considered the second-largest extant reptile in the world, after the saltwater crocodile (Crocodylus porosus).[8][9] Size is sexually dimorphic, with females usually about 30% smaller than males. The crocodile has thick, scaly, heavily armoured skin.

Nile crocodiles are opportunistic apex predators; a very aggressive crocodile, they are capable of taking almost any animal within their range. They are generalists, taking a variety of prey, with a diet consisting mostly of different species of fish, reptiles, birds, and mammals. As ambush predators, they can wait for hours, days, and even weeks for the suitable moment to attack. They are agile predators and wait for the opportunity for a prey item to come well within attack range. Even swift prey are not immune to attack. Like other crocodiles, Nile crocodiles have a powerful bite that is unique among all animals, and sharp, conical teeth that sink into flesh, allowing a grip that is almost impossible to loosen. They can apply high force for extended periods of time, a great advantage for holding down large prey underwater to drown.

Nile crocodiles are relatively social. They share basking spots and large food sources, such as schools of fish and big carcasses. Their strict hierarchy is determined by size. Large, old males are at the top of this hierarchy and have first access to food and the best basking spots. Crocodiles tend to respect this order; when it is infringed, the results are often violent and sometimes fatal. Like most other reptiles, Nile crocodiles lay eggs; these are guarded by the females but also males, making the Nile crocodiles one of few reptile species whose males contribute to parental care. The hatchlings are also protected for a period of time, but hunt by themselves and are not fed by the parents.

The Nile crocodile is one of the most dangerous species of crocodile and is responsible for hundreds of human deaths every year. It is common and is not endangered, despite some regional declines or extirpations in the Maghreb.

15-4-2018 CHOBE RIVER, BOTSWANA - WHITE HEADED LAPWING (Vanellus albiceps)

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

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

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

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

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

A diet primarily composed of insects and small invertebrates sustains the White-crowned Lapwing. It often feeds in small groups, especially when not engaged in breeding activities.

The White-crowned Lapwing is currently classified as Least Concern by the IUCN. It is also a species protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), ensuring international efforts are made to safeguard its future.

15-4-2018 CHOBE RIVER, NAMIBIA - AFRICAN PIED KINGFISHER (Ceryle rudis ssp rudis)

The pied kingfisher (Ceryle rudis) is a striking water kingfisher, known for its black and white plumage and distinctive crest. It is a medium-sized bird, approximately 25 cm in length, with a white face featuring a black mask and a white supercilium. The male is characterized by a double band across the breast, while the female sports a single, often broken, breast band.

When identifying the pied kingfisher, look for its unique black and white barred pattern and prominent crest. The male's double breast band and the female's single broken band are key differentiators between the sexes. The subspecies vary slightly in size and coloration, with some having larger bills or reduced white in their plumage.

This kingfisher is commonly found perched along the edges of clear lakes and rivers, where it can easily spot and dive for fish.

The pied kingfisher is widely distributed across sub-Saharan Africa and southern Asia, from Turkey to India and China. It is a resident species, with most populations not engaging in long migrations.

The pied kingfisher is often seen bobbing its head and flicking its tail while perched. It is a sociable bird, known to form large roosts at night. Its flight is direct and rapid, sometimes reaching speeds close to 50 km/h.

This species is quite vocal, emitting sharp "chirruk chirruk" notes that contribute to its presence being easily detected.

Breeding season for the pied kingfisher typically occurs from February to April in India. They nest in holes excavated in vertical mud banks above water. The nests are tunnel-like, leading to a chamber where a clutch of three to six white eggs is laid. Cooperative breeding is observed in this species, with non-breeding offspring from previous broods assisting in raising the young.

The pied kingfisher can be confused with other black and white kingfishers, but its size, habitat preference, and behavior make it distinctive.

Primarily piscivorous, the pied kingfisher feeds on fish, crustaceans, and large aquatic insects. It employs a unique hunting technique of hovering over water before diving headfirst to catch prey. It is capable of consuming its catch mid-flight, allowing it to hunt over large bodies of water.

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

15-4-2018 CHOBE RIVER, BOTSWANA - WATER THICK NEE (Barhinus Vermiculatus)

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

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

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

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

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

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)

With its yellow feet, which are used to flush prey when feeding in shallow water, the Little Egret is a distinctive member of the heron family. Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland.

Little Egrets first bred in Britain in 1996 and since then have successfully colonised much of southern Britain and Ireland. Most of the breeding colonies have been established within existing Grey Heron colonies, the two species nesting alongside one another.

The winter distribution is also currently restricted to the southern half of Britain & Ireland, despite the fact that young birds are known to move some distance from their natal site.

The little egret, a captivating member of the heron family, Ardeidae, has long enchanted observers with its elegant appearance. Boasting a slender body, pristine white plumage, and long black legs, this bird is the epitome of grace and poise. Found throughout Europe, Africa, Asia, and even as far as Australia, the little egret has a wide distribution, allowing it to grace numerous landscapes and ecosystems with its beauty.

While the little egret itself may not feature prominently in folklore or myths, it is worth noting that its close relatives, the herons and egrets, do have cultural significance in various parts of the world. For instance, in Japanese folklore, the white heron is a revered figure that is often associated with purity, elegance, and transformation. These transformed herons, known as “sagi musume,” are believed to have the ability to take on the form of beautiful women, and are depicted in various forms of traditional Japanese art and theater. This cultural association highlights the admiration and respect for the little egret’s larger family of birds and the captivating charm they possess.

Little egrets favor wetland environments such as marshes, swamps, rivers, lakes, and coastal areas. Their adaptability allows them to thrive in various climates, from temperate to tropical regions. In some parts of the world, these birds are migratory, while in other regions, they maintain a more sedentary lifestyle.

An anecdote that illustrates the adaptability of the little egret can be found in the United Kingdom. Once a rare visitor, this bird has expanded its range and now breeds regularly across southern England, delighting local birdwatchers with its elegant presence.

The little egret’s diet primarily consists of fish, crustaceans, and aquatic insects. They employ various feeding techniques, such as:

Walking through shallow water and using their yellow feet to stir up prey

Employing a “stand and wait” strategy to ambush prey

As opportunistic feeders, little egrets are known to adapt their diet based on available food sources. In one fascinating instance, a little egret was observed using a piece of bread as bait to catch fish in an urban park, demonstrating their intelligence and resourcefulness.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)

Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings, while females are yellow and brown. Both sexes have red eyes.

Trithemis annulata is found in most of Africa and also in France, Cyprus, Greece, India, Iran, Iraq, Israel, Italy, Jordan, Kuwait, Lebanon, Mauritius, Oman, Portugal, Qatar, Réunion, Syria, Turkey, United Arab Emirates, and Yemen. It was also recorded in the Maltese islands in 2005 and found breeding there in 2007 With the advent of global warming, it is increasing its range northwards in Europe and in the late 1990s advanced from southern Spain and southern Italy into France, and from Greece and Turkey into Central Europe. One such place where it has become established is the floodplain of the River Ebro in northeastern Spain.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - EPAULET SKIMMER DRAGONFLY (MALE) (Orthetrum chrysostigma)

Orthetrum chrysostigma, the epaulet skimmer, is a species of dragonfly in the family Libellulidae. It is found in Algeria, Angola, Benin, Botswana, Burkina Faso, Cameroon, Central African Republic, Chad, the Democratic Republic of the Congo, Ivory Coast, Egypt, Equatorial Guinea, Ethiopia, Gambia, Ghana, Guinea, Kenya, Liberia, Libya, Malawi, Mali, Mauritania, Morocco, Mozambique, Namibia, Niger, Nigeria, Senegal, Sierra Leone, Somalia, South Africa, Sudan, Tanzania, Togo, Uganda, Zambia, Zimbabwe, and possibly Burundi as well as Canary Islands, Israel, and Portugal.

Its natural habitats are subtropical or tropical moist lowland forests, dry savanna, moist savanna, subtropical or tropical dry shrubland, subtropical or tropical moist shrubland, rivers, intermittent rivers, shrub-dominated wetlands, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, and freshwater springs. The adults prey on various flying insects. The bodies of adult males are blue, and those of young and females are yellow and brown.

Very widespread and occurs virtually throughout Africa, including North Africa. It also occurs in parts of Southern Europe and the Middle East. In South Africa it occurs virtually throughout, but is scarce in the dry central regions.

The Epaulet Skimmer is a southern European and African dragonfly. A little similar to the Keeled Skimmer of the UK, it has a narrow elongated body with central raised "keel". Above is the attractive pale blue male with turquoise eyes, but the "epaulet" marking on the thorax that gives it its name is not often clear and darkens with age.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - WAVYLEAF MULLEIN (Verbascum sinuatum)

Verbascum sinuatum, commonly known as the scallop-leaved mullein, the wavyleaf mullein, or Candela regia, is a species of perennial herbaceous plants in the genus Verbascum (mullein), growing in heavy soils in Central Asia and the Mediterranean region. It grows to 1.2–1.5 m (3.9–4.9 ft). The plant has an erect inflorescence stem, and is entirely covered with stellate hairs (trichomes) which are not pleasant to the touch.

In the winter, a rosette of broad-leaves grows at the base of the Scallop-leaved mullein and spreads itself on the ground (length 30–50 cm). In the spring, a leafless stalk grows from the base of the plant, splitting into many diagonal stems that can grow as much as 50 to 100 cm. in length, on which the flowers are located. The plant bears simple, emarginate leaves, and has a yellow lamp-shaped flower (hence its name Candela) of 5 petals, blossoming mostly in late May to August, although sometimes as late as October.

The plant's leaves are alternate, rosette, entire, dentate or serrate.

The plant has a broad Irano-Turanian distribution, as well as a broad Mediterranean distribution (stretching from the Mediterranean coastal regions to West and South Iran). The plant is native to Israel, where it grows in the Golan, the Hermon, the coastline of the Mediterranean Sea, Gilboa, Carmel, Samarian Mountains, Judean Mountains, the Jordan Valley, the Sharon valley, Shephelah, Northern Negev, and Eilat Mountains, and the Arabah, typically found in waste habitats, along waysides, and in open chaparrals (shrublands) and phrygana.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - VIOLET DROPWING DRAGONFLY (MALE) (Trithemis annulata)

Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch. Males of this species are violet-red with red veins in the wings, while females are yellow and brown. Both sexes have red eyes.

Trithemis annulata is a robust medium-sized species with a wingspan of 60 mm (2.4 in). The mature male has a dark red head and a yellow labium with a brown central spot. The eyes are red with white spots on the rear edge, and the frons is dark metallic purplish-red. The prothorax is violet with slightly darker longitudinal stripes. The membranous wings have distinctive red veins, the pterostigma is orange-brown, and there is a large orange-brown splash at the base of the hind wings. The abdomen is fairly broad and is pinkish-violet, with purple markings on the top of each segment and blackish markings on the terminal three segments. Females are a similar size to males, but the thorax is brownish, and the abdomen is yellow with dark brown markings. The wings of females lack the red veins of males but have similar orange-brown patches. It is very similar in appearance to the red-veined dropwing (Trithemis arteriosa), but that species has a more slender abdomen and a wedge-shaped black area on either side of the tip of the abdomen.

Trithemis annulata is found in most of Africa and also in France, Cyprus, Greece, India, Iran, Iraq, Israel, Italy, Jordan, Kuwait, Lebanon, Mauritius, Oman, Portugal, Qatar, Réunion, Syria, Turkey, United Arab Emirates, and Yemen. It was also recorded in the Maltese islands in 2005 and found breeding there in 2007 With the advent of global warming, it is increasing its range northwards in Europe and in the late 1990s advanced from southern Spain and southern Italy into France, and from Greece and Turkey into Central Europe. One such place where it has become established is the floodplain of the River Ebro in northeastern Spain.

Trithemis annulata is an adaptable species, and the adults can tolerate a range of habitats, including semi-arid rangeland. They can be seen flying near sluggish rivers, in marshes, and also beside still-water ponds. They are sometimes seen in brackish water habitats, although it is unclear whether they actually breed in salty water. The larvae develop rapidly, so these dragonflies can make use of temporary water bodies for breeding. Males are often seen perching on the twigs of waterside shrubs and on rocks in the sunshine, but in the evening or when the sun is obscured, they move into trees.

The female T. annulata is thought to deposit her eggs by flying over the surface and dipping the tip of her abdomen in the water. The larvae develop in water where they are aggressive predators. The adults are also predators, using their excellent eyesight to detect prey and their legs to hold and carry their victims.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - VIOLET DROPWING DRAGONFLY (FEMALE) (Trithemis annulata)

Trithemis annulata, commonly known as the violet dropwing, violet-marked darter, purple-blushed darter, or plum-coloured dropwing, is a species of dragonfly in the family Libellulidae. It is found in most of Africa, the Middle East, the Arabian Peninsula, and southern Europe. These dragonflies are called dropwings because of their habit of immediately lowering their wings after landing on a perch.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - SCARLET DARTER DRAGONFLY (FEMALE) (Crocothemis erythraea)

The scarlet dragonfly (Crocothemis erythraea) is a species of dragonfly in the family Libellulidae. Its common names include broad scarlet, common scarlet-darter, and scarlet darter.

The scarlet dragonfly is a common species in southern Europe and throughout Africa. It also occurs across western Asia as far as southern China. It is a very rare vagrant in Britain. Its first record in the country was at Hayle Kimbro Pool, The Lizard, Cornwall, on 7 August 1995. Since then there have been a few further records at scattered locations throughout Britain.

A wide range of both running and standing waters, except those that are shaded. Adults may be found some distance from water in habitats ranging from desert to open woodland; absent from dense forest.

Crocothemis erythraea can reach a length of 33–44 millimetres (1.3–1.7 in). These dragonflies haves a flattened and rather broad abdomen. The adult male scarlet dragonfly has a bright scarlet red, widened abdomen, with small amber patches at the bases of the hindwings. Also the veins on the leading edges of the wings are red. Females and immatures are yellow-brown and have a conspicuous pale stripe along the top of the thorax.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - GREAT WILLOWHERB (Epilobium hirsutum)

Epilobium hirsutum is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie.

It is a tall, perennial plant, reaching up to 2 metres in height. The robust stems are profusely hairy with soft spreading hairs. The hairy leaves are 2–12 cm long and 0.5–3.5 cm wide. They are long and thin and are widest below the middle. They have sharply toothed edges and no stalk. The large flowers have four notched petals. These are purple-pink and are usually 10–16 mm long.  The stigma is white and has four lobes. The sepals are green.

The native range of the species includes North Africa, most of Europe up to southern Sweden, and parts of Asia. It is absent from much of Scandinavia and north-west Scotland. It has been introduced to North America and Australia. It typically grows in wet or damp habitats without dense tree-cover up to 2,500 metres above sea-level. Common habitats include marshland, ditches and the banks of rivers and streams. It flowers from June to September, with a peak in July and August. The flowers are visited by many types of insects, and can be characterized by a generalized pollination syndrome. A number of insects feed on the leaves including the elephant hawkmoth, Deilephila elpenor.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - CONTINENTAL STRIPED SHIELD BUG (Graphosoma italicum ssp italicum)

Graphosoma italicum is a species of shield bug in the family Pentatomidae. It is also known as the striped bug (or Italian striped bug) and minstrel bug.

G. italicum can reach a length of 8–12 mm (0.31–0.47 in). The body is almost round, with a large shield. The basic color of the upperside of the body is red, with wide black longitudinal stripes. The pronotum has six black bands. The antennae are black. Also the sides of the abdominal segments (connexivum) are red with many small black spots. The legs are mostly black, which distinguishes it from its relative, G. lineatum.

G. italicum is distributed across the Western Palearctic and occurs in the entire Mediterranean area, with the northern limit of distribution fluctuating strongly. In recent decades, the northern border in western and central Europe has expanded strongly to the north, so that the species now occurs as far as the North Sea and Baltic Sea (Jutland and southern Finland). In Germany, the type occurs everywhere with exception of the northwest and is not rare regionally. In Austria, it is widespread, but only locally frequent. The insects populate open to half-shady areas in dry to more humid habitats. The subspecies G. i. sardiniensis occurs only in Sardinia.

5-8-2018 VILLALONGA RESERVOIR, VALENCIA - CHICORY (Cichorium intybus)

Common chicory (Cichorium intybus) is a somewhat woody, perennial herbaceous plant of the family Asteraceae, usually with bright blue flowers, rarely white or pink. Native to Europe, it has been introduced to the Americas and Australia.

Many varieties are cultivated for salad leaves, chicons (blanched buds), or roots (var. sativum), which are baked, ground, and used as a coffee substitute and food additive. In the 21st century, inulin, an extract from chicory root, has been used in food manufacturing as a sweetener and source of dietary fiber. Chicory is also grown as a forage crop for livestock.

When flowering, chicory has a tough, grooved, and more or less hairy stem. It can grow to 1.5 metres (5 feet) tall. The leaves are stalked, lanceolate and unlobed; they range from 7.5–32 centimetres (3–12+1⁄2 inches) in length (smallest near the top) and 2–8 cm (3⁄4–3+1⁄4 in) wide.[5] The flower heads are 3–5 cm (1+1⁄4–2 in) wide, and usually light blue or lavender; it has also rarely been described as white or pink. Of the two rows of involucral bracts, the inner is longer and erect, the outer is shorter and spreading. It flowers from March until October. The seed has small scales at the tip.

5-8-2018 POTRIES RIO SERPIS, VALENCIA - JERUSALEM ARTICHOKE (Helianthus tuberosus)

The Jerusalem artichoke (Helianthus tuberosus), also called sunroot, sunchoke, wild sunflower, topinambur, or earth apple, is a species of sunflower native to central North America. It is cultivated widely across the temperate zone for its tuber, which is used as a root vegetable.

Helianthus tuberosus is a herbaceous perennial plant growing to 1.5–3 m (4 ft 11 in – 9 ft 10 in) tall with opposite leaves on the lower part of the stem but alternate towards the top. The leaves have a rough, hairy texture. Larger leaves on the lower stem are broad ovoid-acute and can be up to 30 cm (12 in) long. Leaves higher on the stem are smaller and narrower.

The flowers are yellow and produced in capitate flowerheads, which are 5–10 cm (2–4 in) in diameter, with 10–20 ray florets and 60 or more small disc florets. The flowers are briefly fragrant, giving off a light, vanilla-chocolate perfume.

The tubers are often elongated and uneven, typically 7.5–10 cm (3–3+7⁄8 in) long and 3–5 cm (1–2 in) thick, and vaguely resembling a ginger root in appearance, with a crisp and crunchy texture when raw. They vary in color from pale brown to white, red, or purple.

Before the arrival of Europeans, indigenous peoples cultivated H. tuberosus as a food source. The tubers persist for years after being planted, so the species expanded its range from central North America to the eastern and western regions. Early European colonists learned of this and sent tubers back to Europe, where they became a popular crop and naturalized there. It later gradually fell into obscurity in North America, but attempts to market it commercially were successful in the late 1900s and early 2000s.

The tuber contains about 2% protein, no oil, and little starch. It is rich in the carbohydrate inulin (8 to 13%, which is a polymer of the monosaccharide fructose. Tubers stored for any length of time convert their inulin into its component, fructose. Jerusalem artichokes have an underlying sweet taste because of the fructose, which is about one and a half times as sweet as sucrose.

It has also been reported as a folk remedy for diabetes: since inulin is not assimilated in the intestine, it does not cause a glycemic spike as potatoes would. Temperature variances have been shown to affect the amount of inulin the Jerusalem artichoke can produce. It makes less inulin in a colder region than when it is in a warmer region.

Originating in North America, the Jerusalem artichoke can now be found in several countries in North and South America, Europe, Asia, and Australia. In Central Europe it is one of the most expanding invasive plant species. It can grow in many geo-climatic regions and different types of soils. However, Jerusalem artichoke prefers moist habitats and seems to be less tolerant of dry conditions.

Because of its ecological and biological attributes, the Jerusalem artichoke is highly competitive with other plant species. For instance, the carbohydrates in the tubers serve as an energy source for rapid growth in spring. The plant expands rapidly and creates shading, which has a suppressing effect on neighbouring plants. Therefore, the risk of outcompeting and repressing the growth of native plants is increased.

14-4-2018 CHOBE RIVER, NAMIBIA - SOUTHERN RED BISHOP (Euplectes orix)

The southern red bishop or red bishop (Euplectes orix) is a small passerine bird belonging to the bishop and widowbird genus Euplectes in the weaver family, the Ploceidae. It is common in wetlands and grassland in Africa south of the Equator. North of the Equator, it is replaced by the northern red bishop or orange bishop (E. franciscanus) which was formerly regarded as a subspecies of this species.

It occurs from South Africa north to Angola, southern and eastern parts of the Democratic Republic of Congo, northern Zambia southern Uganda north-east Nigeria and south-west Kenya. It is largely absent from the Namib Desert and Kalahari.

In the breeding season it is found near water among grass, reeds, sedges or crops such as sugar cane. Outside the breeding season it will venture into drier grassland and savanna habitats.

4-8-2018 MONTE CORONA, VALENCIA - GLOSSY ABELIA (Linnaea × grandiflora)

Abelia × grandiflora is a hybrid species of flowering plant in the honeysuckle family Caprifoliaceae, raised by hybridising A. chinensis with A. uniflora.

It is a deciduous or semi-evergreen multistemmed shrub with rounded, spreading, or gracefully arching branches to 1 to 1.8 m (3.3 to 5.9 ft) tall. The leaves are ovate, glossy, dark green, and 2–6 cm (0.8–2.4 in) long. The fragrant flowers are produced in clusters, white, tinged pink, bell-shaped, to 2 cm long.[2] Unlike most flowering shrubs in cultivation, the species blooms from late summer to well into the autumn.

The Latin specific epithet grandiflora means "abundant flowers". [note, a review of Harrison, Lorraine (2012). RHS Latin for Gardeners reveals it actually says "with large flowers". New Latin, from Latin grandis great + flor-, flos flower, and the Oxford English Dictionary says "Bearing large flowers". However these flowers are not large, but they are abundant, so further research is warranted. "Abelia", the common name and genus name, honors Clarke Abel, physician and naturalist who collected seeds and plants on a British expedition to China in 1817.

4-8-2018 MONTE CORONA, VALENCIA - BE STILL TREE (Cascabela thevetia)

Cascabela thevetia (synonym Thevetia peruviana) is a poisonous plant native throughout Mexico and in Central America, and cultivated widely as an ornamental. It is a relative of Nerium oleander, giving it a common name yellow oleander.

'Cascabel', 'cascavel' or 'cascabela' is Spanish for a small bell, a snake's rattle or a rattlesnake itself. The allusion may also be to the plant's toxicity comparable to the venom of a rattlesnake. The latin specific name thevetia commemorates André de Thevet (1516-1590), a French Franciscan priest and explorer, who explored Brazil and Guiana (where the plant is known as chapéu-de-napoleão, ie, Napoleon's hat).

Cascabela thevetia is an evergreen tropical shrub or small tree. Its leaves are willow-like, linear-lanceolate, and glossy green in color. They are covered in waxy coating to reduce water loss (typical of oleanders). Its stem is green turning silver/gray as it ages. Flowers bloom from summer to fall. The long funnel-shaped sometimes-fragrant yellow (less commonly apricot, sometimes white) flowers are in few-flowered terminal clusters.[5] Its fruit is deep red-black in color encasing a large seed that bears some resemblance to a 'Chinese lucky nut.'[clarification needed]

Cascabela thevetia is effectively drought resistant and tolerant to high temperatures, hence found in various semi-arid regions of India.[citation needed]

Its bright yellow flowers are used for religious purposes in India, worshipping by Hindu devotees.[citation needed]

All parts of the C. thevetia plant are toxic to most vertebrates as they contain cardiac glycosides. Many cases of intentional and accidental poisoning of humans are known.

The main toxins are the cardenolides called thevetin A and thevetin B; others include peruvoside, neriifolin, thevetoxin and ruvoside. These cardenolides are not destroyed by drying or heating and are very similar to digoxin from Digitalis purpurea. They produce gastric upset and cardiotoxic effects. Antidotes include atropine and digoxin immune fabs (antibodies) and treatment may include oral administration of activated charcoal. Ovine polyclonal anti-digitoxin Fab fragment antibody (DigiTAb; Therapeutic Antibodies Inc.) can be used to treat T. peruviana poisoning, but for many countries the cost is prohibitive.

A few bird species are however known to feed on them without any ill effects. These include the sunbirds, Asian koel, red-whiskered bulbul, white-browed bulbul, red-vented bulbul, brahminy myna, common myna and common grey hornbill.

In South India and in Sri Lanka swallowing the seeds of Thevetia peruviana[19] (Kaneru කණේරු (Sinhala), Manjal arali (Tamil)) is one of the preferred methods for suicides in villages where they are grown in abundance.

Extracts from C. thevetia are reported to possess antispermatogenic activity in rats.

In 2023, the US Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) reported on weight loss supplements substituting Crataegus mexicana and Aleurites moluccanus for C. thevetia, following multiple hospitalizations.

Cascabela thevetia is cultivated as an ornamental plant, and planted as large flowering shrub or small ornamental tree standards in gardens and parks in temperate climates. In frost prone areas it is container plant, in the winter season brought inside a greenhouse or as a house plant. It tolerates most soils and is drought tolerant.

The plant's toxins have been tested in experiments for uses in biological pest control. T. peruviana seed oil was used to make a 'paint' with antifungal, antibacterial and anti-termite properties.

15-4-2018 CHOBE RIVER, BOTSWANA - BARN SWALLOW (Hirundo rustica)

The barn swallow (Hirundo rustica) is a migratory passerine bird, recognized as the most widespread species of swallow in the world. It is a distinctive bird with blue upperparts and a long, deeply forked tail, known for its graceful flight and agile maneuvers. The adult male of the nominate subspecies is 17–19 cm in length, including elongated outer tail feathers, and has a wingspan of 32–34.5 cm. It is adorned with a rufous forehead, chin, and throat, which are set apart from the off-white underparts by a broad dark blue breast band. The outer tail feathers are elongated, contributing to the iconic "swallow tail."

The barn swallow can be identified by its steel blue upperparts, a rufous face, and a dark blue breast band that separates the rufous from the off-white underparts. The deeply forked tail is a key characteristic, with a line of white spots across the upper tail's outer end. Females resemble males but have shorter tail streamers and less glossy blue coloring. Juveniles are browner with paler rufous faces and whiter underparts, lacking the adult's long tail streamers.

15-4-2018 CHOBE NATIONAL PARK, 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.

The lilac-breasted roller (Coracias caudatus) is an African bird of the roller family, Coraciidae. It is widely distributed in Southern and Eastern Africa, and is a vagrant to the southern Arabian Peninsula.[1] It prefers open woodland and savanna, and it is for the most part absent from treeless places. Usually found alone or in pairs, it perches at the tops of trees, poles or other high vantage points from where it can spot insects, amphibians and small birds moving about on the ground.

Nesting takes place in a natural hole in a tree where a clutch of 2–4 eggs are laid, and incubated by both parents, who are extremely aggressive in defence of their nest, taking on raptors and other birds. During the breeding season the male will rise to a fair height (69 to 144 metres), descending in swoops and dives, while uttering harsh, discordant cries. The sexes do not differ in coloration, and juveniles lack the long tail streamers of adults.

Alternative names for the lilac-breasted roller include the fork-tailed roller, lilac-throated roller (also used for a subspecies of purple roller) and Mosilikatze's roller.

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.

The call is a harsh, sawing "rak rak rak," typically delivered in flight. The bird often perches to vocalize.

The lilac-breasted roller is likely monogamous, nesting solitarily. Both sexes incubate the clutch of 2–4 eggs. The nest is located in a natural hole in a tree or termite mound, and the young are altricial, becoming fully feathered after 19 days.

Their diet consists of arthropods and small vertebrates, including insects, spiders, scorpions, and small birds. They hunt from perches, swooping down to catch prey on the ground or in the air.

The IUCN lists the lilac-breasted roller as Least Concern, with a stable population size and a large range.
