18-7-2019 OLIVA MARJAL, VALENCIA - PURPLE LOOSESTRIFE (Lythrum salicaria)

Lythrum salicaria or purple-loosestrife is a flowering plant belonging to the family Lythraceae. It should not be confused with other plants sharing the name loosestrife that are members of the genus Lysimachia in the family Primulaceae. This herbaceous perennial plant is native to temperate regions of Europe, Asia, northern Africa, and eastern Australia.

Lythrum salicaria can grow 1–2 m (3 ft 3 in – 6 ft 7 in) tall, forming extensive clonal colonies, with numerous erect stems growing from a single woody root mass. The stems are reddish-purple and square in cross-section. The leaves are lanceolate, 3–10 centimetres (1–4 in) long and 5–15 millimetres (3⁄16–9⁄16 in) broad, downy and sessile, and arranged opposite or in whorls of three.

The flowers are reddish purple, 10–20 millimetres (1⁄2–3⁄4 in) in diameter, with six petals (occasionally five) and 12 stamens, and are clustered tightly in verticillasters in the axils of bracts or leaves. There are three different flower types, with the stamens and style of different lengths, short, medium or long; each flower type can only be pollinated by one of the other types, not the same type, thus ensuring cross-pollination between different plants. For instance, if the pistil is medium length, then the stamens will be long and short, but not medium. The flowers are visited by many types of insects, and can be characterised by a generalised pollination syndrome.

The fruit is a small 3–4 millimetres (1⁄8–5⁄32 in) capsule containing numerous minute seeds. Flowering lasts throughout the summer. When the seeds are mature, the leaves often turn bright red through dehydration in early autumn; the red autumn colour may last for almost two weeks. The dead stalks from previous growing seasons are brown.

18-7-2019 OLIVA MARJAL, VALENCIA - 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.

The barn swallow favors open country with low vegetation, such as pastures, meadows, and farmland, often near water. It avoids heavily wooded or steep areas and densely built-up locations. The species typically nests in man-made structures like barns and stables, or under bridges and wharves.

This bird has a vast global range, breeding across the Northern Hemisphere and wintering in much of the Southern Hemisphere. Its distribution spans Europe, Asia, Africa, and the Americas.

Barn swallows are semi-colonial and may settle in groups. They exhibit site fidelity, often returning to the same location annually for breeding. The species is known for its aerial insectivory, catching insects in flight with remarkable agility.

The barn swallow communicates with a variety of calls, including a "witt or witt-witt" and a loud "splee-plink" when excited or deterring intruders. Alarm calls include a sharp "siflitt" for terrestrial predators and a "flitt-flitt" for avian predators. The male's song, used for territory defense and mate attraction, consists of a twittering warble followed by a series of musical notes.

Barn swallows are monogamous and often mate for life, with the male arriving first at the breeding grounds to select a nest site. They build cup-shaped mud nests lined with soft materials, frequently in colonies where each pair defends a territory. The female typically lays two to seven spotted white eggs, with the clutch size varying by latitude.

The barn swallow can be confused with other Hirundo species and the welcome swallow in overlapping ranges. However, its red face and blue breast band distinguish it from African species, and it differs from the welcome swallow by its deeply forked tail and white tail spots.

The diet consists mainly of flying insects, which the barn swallow captures in open areas or follows animals and humans to catch disturbed prey. It may also pick insects from water surfaces, walls, and plants. The species drinks and bathes by skimming over water bodies.

The barn swallow is classified as Least Concern by the IUCN, with an extensive range and large global population. While not endangered, local declines may occur due to specific threats, such as habitat loss or pesticide use. However, the species has benefited from human expansion and the availability of nesting sites.

18-7-2019 OLIVA MARJAL, VALENCIA - RED EARED SLIDER TERRAPIN (Trachemys scripta ssp. elegans)

The red-eared slider or red-eared terrapin (Trachemys scripta elegans) is a subspecies of the pond slider (Trachemys scripta), a semiaquatic turtle belonging to the family Emydidae. It is the most popular pet turtle in the United States, is also popular as a pet across the rest of the world, and is the most invasive turtle. It is the most commonly traded turtle in the world.

The red-eared slider is native from the Midwestern United States to northern Mexico, but has become established in other places because of pet releases, and has become invasive in many areas where it outcompetes native species. The red-eared slider is included in the list of the world's 100 most invasive species.

18-7-2019 OLIVA MARJAL, VALENCIA - SPECKLED WOOD BUTTERFLY (Pararge aegeria)

The speckled wood (Pararge aegeria) is a butterfly found in and on the borders of woodland areas throughout much of the Palearctic realm. The species is subdivided into multiple subspecies, including Pararge aegeria aegeria, Pararge aegeria tircis, Pararge aegeria oblita, and Pararge aegeria insula. The color of this butterfly varies between subspecies. The existence of these subspecies is due to variation in morphology down a gradient corresponding to a geographic cline.

The background of the wings ranges from brown to orange, and the spots are either pale yellow, white, cream, or a tawny orange. The speckled wood feeds on a variety of grass species. The males of this species exhibit two types of mate locating behaviors: territorial defense and patrolling. The proportion of males exhibiting these two strategies changes based on ecological conditions. The monandrous female must choose which type of male can help her reproduce successfully. Her decision is heavily influenced by environmental conditions.

The average wingspan of both males and females is 5.1 cm (2 in), although males tend to be slightly smaller than females. Furthermore, males possess a row of grayish-brown scent scales on their forewings that is absent in the females. Females have brighter and more distinct markings than males. The subspecies P. a. tircis is brown with pale yellow or cream spots and darker upperwing eyespots. The subspecies P. a. aegeria has a more orange background and the hindwing underside eyespots are reddish brown rather than black or dark gray. 

The two forms gradually intergrade into each other. Subspecies P. a. oblita is a darker brown, often approaching black with white rather than cream spots. The underside of its hindwings has a marginal pale purple band and a row of conspicuous white spots. The spots of subspecies P. a. insula are a tawny orange rather than a cream color. The underside of the forewings has patches of pale orange, and the underside of the hindwing has a purple-tinged band. Although there is considerable variation with each subspecies, identification of the different subspecies is manageable.

19-7-2019 MONTE CORONA, VALENCIA - CRICKET BAT ORBWEAVER (Mangora acalypha)

Mangora acalypha, also known by its common name cricket-bat orbweaver,is a species of spider in the family Araneidae, found throughout the Palearctic realm. This species was originally described by Charles Athanase Walckenaer in 1802 as Aranea acalypha.

Habitat

Mangora acalypha is common in meadows, forests and gardens.

The Cricket-bat Orbweaver is a species of spider, scientifically known as Mangora acalypha, named for the black, cricket-bat-shaped markings on its abdomen. It is a common spider in the Palearctic region, inhabiting meadows, forests, and gardens, where it constructs typical orb-shaped webs to catch flying insects. This spider is not considered medically significant to humans, as it directs its venom toward its prey. 

Key characteristics

Scientific Name: Mangora acalypha

Common Names: Cricket-bat Orbweaver, Cricket-bat Spider, Streifenkreuzspinne (in German)

Family: Araneidae (orb-weavers)

Appearance: Known for a black marking on its abdomen that resembles a cricket bat.

Habitat: Meadows, forests, and gardens, and is becoming more common in gardens.

Behavior: Builds typical orb webs to catch flying insects like flies, mosquitos, and moths.

Venom: Not considered dangerous to humans, as its venom is primarily used to subdue prey.

23-5-2019 MANA POOLS, ZIMBABWE - SOUTHERN RED BILLED HORNBILL (Tockus rufirostris)

The southern red-billed hornbill (Tockus rufirostris) is a species of hornbill in the family Bucerotidae, which is native to the savannas and dryer bushlands of southern Africa. It is replaced by a near-relative, the Damara red-billed hornbill, in the arid woodlands of western Namibia. All five red-billed hornbills were formerly considered conspecific.

The sexes are similar, but males are larger and heavier. Males also have somewhat longer bills, with the lower mandible coloured black to a variable extent. It is distinguishable from other red-billed hornbills by the combination of yellow iris and pale orbital skin (pink to greyish), and the ample blackish plumage streaking from the ear coverts to the side of the neck. The throat is white, and the wing coverts clearly spotted.

The call consists of an accelerating series notes, kuk kuk kuk ... which ends in a crescendo of double notes, kuk-we kuk-we. Unlike other red-billed hornbills, Southern red-billed hornbills do not raise their wings in display.

It is found from Malawi and Zambia to southern Angola, northeastern Namibia, Botswana, Zimbabwe, eastern Eswatini and northern South Africa (Transvaal and northern KZN province). It occurs in the upper Zambezi valley of Mozambique, but is mostly absent from the eastern lowlands.

16-7-2019 MONTE CORONA, VALENCIA - GREAT TIT (Parus major)

The great tit (Parus major) is a small passerine bird, easily recognized by its black head and neck, striking white cheeks, olive upperparts, and vibrant yellow underparts. This bird is the most widespread species in the genus Parus, found across Europe, the Middle East, Central Asia, and parts of North Africa.

Males are characterized by their bright plumage, with a black bib that extends down the belly, bordered by a lemon-yellow breast. Females and juveniles are similar but have duller coloration. The black line down the belly is also narrower and sometimes broken in these birds.

Great tits favor a variety of woodland habitats, including deciduous and mixed forests, forest edges, and even urban parks and gardens. They are also found in riverine woodlands and, in some regions, boreal taiga.

17-7-2019 BONAIRE, VALENCIA - EUROPEAN BEE-EATER (Merops apiaster)

The European bee-eater, Merops apiaster, is a bird of arresting beauty and grace. Its plumage is a kaleidoscope of warm hues, with brown and yellow adorning its upper parts, while the wings boast a vibrant green. The beak, a stark black, contrasts sharply with the bird's colorful attire. This slender avian can reach a length of 27–29 cm, including the elongated central tail feathers that add to its elegance. Both sexes are similar in appearance, though the female may sport greener shoulder feathers compared to the male's gold.

When identifying the European bee-eater, look for its distinctive coloration and sleek profile. The non-breeding plumage is more subdued, with a blue-green back and the absence of elongated central tail feathers. Juveniles resemble non-breeding adults but exhibit less variation in feather colors. During the moulting period, adults transition to breeding plumage, which is completed before their winter migration to Africa.

These birds favor open country in warmer climates, often found in proximity to sandy banks and river shores where they can nest and forage with ease.

The European bee-eater breeds across southern and central Europe, parts of northern and southern Africa, and western Asia. While the southern African population remains resident year-round, others migrate to tropical Africa for the winter. Occasionally, they are seen north of their typical range, with sporadic breeding in northern Europe.

Gregarious by nature, European bee-eaters nest colonially in sandy banks, with communal tendencies extending to feeding and roosting. Courtship involves the male presenting the female with large prey items, a gesture of both affection and sustenance.

The call of the European bee-eater is a melodious and liquid "prreee" or "prruup," a sound as mellow as the bird's demeanor.

Breeding season sees these birds tunneling into sandy banks to lay their spherical white eggs, with both parents sharing the duties of incubation and care. The eggs hatch after about three weeks, and the young are raised with communal diligence.

While the European bee-eater is distinctive, it may be confused with other bee-eater species. However, its unique coloration and tail feathers generally set it apart.

True to their name, European bee-eaters feast primarily on bees, wasps, and hornets. They exhibit remarkable skill in catching these insects mid-flight and have a unique method of removing the sting before consumption. Their diet is predominantly composed of Hymenoptera, particularly the European honey bee.

The IUCN lists the European bee-eater as Least Concern, indicating a stable population without immediate threats to its survival. However, their interactions with bee populations and apiaries are of interest to conservationists and apiculturists alike.

17-7-2019 ALBUFERA, VALENCIA - WHISKERED TERN (JUVENILE) (Chlidonias niger)

The Whiskered Tern, Chlidonias hybrida, is a member of the tern family Laridae, exhibiting a swallow-like appearance, as suggested by its genus name derived from the Ancient Greek khelidonios. This species is the largest of the marsh terns, showcasing a blend of features from both the white Sterna terns and the black tern.

Adult Whiskered Terns in summer plumage are characterized by their robust bill, measuring 29–34 mm in males and 25–27 mm in females, with a pronounced gonys. They possess a black cap and a short, forked-looking tail. The cheeks are white, and the legs and bill are a vibrant red. Juveniles display a white-flecked crown and a more uniformly blackish hindcrown, while the winter adult has a similar pattern with additional white flecking. The black ear-coverts create a C-shaped band when viewed from above. Throughout the year, the rump maintains a pale grey hue. The call of the Whiskered Tern is a distinctive "krekk."

Whiskered Terns breed in colonies on inland marshes, often in the company of black-headed gulls, which offer a degree of protection.

The Whiskered Tern has several geographical races, varying mainly in size and minor plumage details. The Eurasian Whiskered Tern (C. h. hybrida) is found in warmer parts of Europe and the Palearctic, while the African Whiskered Tern (C. h. delalandii) resides in east and south Africa, and the Australasian Whiskered Tern (C. h. javanicus) ranges from Java to Australia. The tropical forms are resident, but European and Asian birds migrate south to Africa and the Indian Subcontinent for wintering.

European and Asian Whiskered Terns are migratory, traveling south during the winter months. A tagged individual was observed in April 2021 at the Manakudi Bird Sanctuary in Tamil Nadu, India.

The Whiskered Tern is known for its characteristic "krekk" call.

This species breeds in colonies on inland marshes, sometimes amongst black-headed gulls.

The diet of the Whiskered Tern includes small fish, amphibians, insects, and crustaceans.

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

17-7-2019 ALBUFERA, VALENCIA - EUROPEAN TURTLE DOVE (Sternula albifrons)

It is a bird of open rather than dense woodlands, and frequently feeds on the ground. It will occasionally nest in large gardens, but is usually extremely timid, probably due to the heavy hunting pressure it faces during migration. The flight is often described as arrowy, but is not remarkably swift.

The nuptial flight, high and circling, is like that of the common wood pigeon, but the undulations are less decided; it is accompanied by the whip-crack of the downward flicked wings. The arrival in spring is heralded by its cooing or purring song, a rather deep, vibrating "turrr, turrr".

17-7-2019 ALBUFERA, VALENCIA - NOMAD DRAGONFLY (FEMALE) (Sympetrum fonscolombii)

The red-veined darter or nomad (Sympetrum fonscolombii) is a dragonfly of the genus Sympetrum.

Sympetrum fonscolombii was named under the protonym Libellula fonscolombii by the Belgian entomologist Edmond de Sélys Longchamps, in 1840, in honor of the French entomologist Étienne of Fonscolombe (hence the species name). Its name is sometimes spelt fonscolombei instead of fonscolombii but Askew (2004) gives the latter as the correct spelling.

Sympetrum fonscolombii can reach a body length of 38–40 millimetres (1.5–1.6 in). This species is similar to other Sympetrum species but a good view with binoculars should give a positive identification, especially with a male.

Males have a red abdomen, redder than many other Sympetrum species. The frons and the thorax are red-brown. The eyes are brown above and blue/grey below. The wings have red veins and the wing bases of the hind-wings are yellow. The pterostigma is pale yellow with a border of black veins.

Female are similar but the abdomen is ochre yellow, not red, with two black lines along each side. The wings have yellow veins at the costa, leading edge and base, not red veins as found in the males. The legs of both sexes are mostly black with some yellow.

Immature males are like females but often with more red and a single line along each side of the abdomen.

17-7-2019 ALBUFERA, VALENCIA - BLACK WINGED STILT (Himantopus himantopus)

The Black-winged Stilt has a wide range, extending across Europe, Asia, and Africa. Some populations migrate to coastal regions in winter, while others in milder climates may remain resident or engage in short-range movements.

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

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

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

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

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

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

17-7-2019 ALBUFERA, VALENCIA - GULL BILLED TERN (JUVENILE) (Gelochelidon nilotica)

The Gull-billed Tern, Gelochelidon nilotica, is a robust bird, akin in stature to the Sandwich Tern. It boasts a stout, gull-like bill, broad wings, and lengthy legs. In its summer plumage, the adult displays grey upperparts, stark white underparts, a jet-black cap, and matching black bill and legs. The species measures 33–42 cm in length with a wingspan of 76–91 cm, and weighs between 150–292 g.

In its non-breeding attire, the Gull-billed Tern loses its black cap, revealing a dark eye patch reminiscent of a Forster's Tern or a Mediterranean Gull. Juveniles bear a paler mask and resemble winter adults. The juvenile Sandwich Tern, with its shorter bill, is often mistaken for the Gull-billed Tern in regions where the latter is scarce.

The Gull-billed Tern is found in a variety of habitats, including lakes, marshes, and coastal regions such as bays and earthen levees. In Eurasia, it is commonly seen in freshwater areas, whereas in North America, it is almost exclusively associated with saltwater coastal environments.

This species enjoys a wide distribution, breeding in southern Europe, temperate and eastern Asia, North America's coasts, and eastern South America. It exhibits post-breeding dispersal, with northern populations migrating to winter in Africa, the Caribbean, northern South America, southern Asia, and New Zealand.

17-7-2019 ALBUFERA, VALENCIA - STRETCH SPIDER (Genus Tetragnatha)

Tetragnatha is a genus of long-jawed orb-weavers found all over the world. It was first described by Pierre André Latreille in 1804, and contains hundreds of species. Most occur in the tropics and subtropics, and many can run over water. They are commonly called stretch spiders in reference to their elongated body form and their ability to hide on blades of grass or similar elongated substrates by stretching their front legs forward and the others behind them.

Species in this genus are found worldwide, including Greenland.

Tetragnatha species occupy the tall herb and tree layer. They construct orb webs, usually in vegetation near or above streams and ponds. Several studies have reported that they build their webs near slow-flowing streams in sunlit areas. Without access to a humid habitat, these spiders suffer from dehydration. The webs are short-lived, being taken down and digested daily or even more frequently. Webs are usually horizontally inclined and consist of an open hub with 30 to 40 viscid spirals. The spider hangs underneath the central hub of the web with its long front legs directed forward.

These spiders are capable of walking over water surfaces at a very fast pace, with legs I and II moving alternately in a diagonal rhythm while legs III and IV are dragged behind. When at rest on vegetation, the body is pressed against the substrate with the long front legs stretched forward.

One of the biggest and most common species is T. extensa, which has a holarctic distribution. It can be found near lakes, river banks or swamps. Large numbers of individuals can often be found in reeds, tall grass, and around minor trees and shrubs.

23-5-2019 MANA POOLS, ZIMBABWE - CAPE WILD DOG (Lycaon pictus ssp. pictus)

The African wild dog (Lycaon pictus), also called painted dog and Cape hunting dog, is a wild canine native to sub-Saharan Africa. It is the largest wild canine in Africa, and the only extant member of the genus Lycaon, which is distinguished from Canis by dentition highly specialised for a hypercarnivorous diet and by a lack of dewclaws.

It is estimated that there are around 6,600 adults (including 1,400 mature individuals) living in 39 subpopulations, all threatened by habitat fragmentation, human persecution and outbreaks of disease. As the largest subpopulation probably consists of fewer than 250 individuals, the African wild dog has been listed as endangered on the IUCN Red List since 1990.

The African wild dog is a specialized hunter of terrestrial ungulates, mostly hunting at dawn and dusk, but also displays diurnal activity. It captures its prey by using stamina and cooperative hunting to exhaust them. Its natural competitors are lions and spotted hyenas: the former will kill the dogs where possible whilst the latter are frequent kleptoparasites. Like other canids, the African wild dog regurgitates food for its young but also extends this action to adults as a central part of the pack's social unit. The young have the privilege of feeding first on carcasses.

The African wild dog has been revered in several hunter-gatherer societies, particularly those of the San people and Prehistoric Egypt.

The African wild dog occurs foremost in Southern and East Africa. It is rare in North Africa and mostly absent in West Africa, with the only potentially viable population occurring in Senegal's Niokolo-Koba National Park. It is occasionally sighted in other parts of Senegal, Guinea and Mali. Its distribution is patchy in East Africa. It inhabits mostly savannas and arid zones, generally avoiding forested areas. This preference is likely linked to its hunting habits, which require open areas that do not obstruct vision or impede pursuit. It travels through scrubland, woodland and montane areas in pursuit of prey. A forest-dwelling population has been identified in the Harenna Forest, a wet montane forest up to an elevation of 2,400 m (7,900 ft) in the Bale Mountains of Ethiopia. At least one record exists of a pack being sighted on the summit of Mount Kilimanjaro.[26] In Zimbabwe, it has been recorded at the elevation of 1,800 m (5,900 ft).[9] In Ethiopia, several packs were sighted at elevations of 1,900 to 2,800 m (6,200 to 9,200 ft), and a dead individual was found in June 1995 at 4,050 m (13,290 ft) on the Sanetti Plateau. A stable population comprising more than 370 individuals is present in Kruger National Park.

The African wild dog have strong social bonds, stronger than those of sympatric lions and spotted hyenas; thus, solitary living and hunting are extremely rare in the species. It lives in permanent packs consisting of two to 27 adults and yearling pups. The typical pack size in the Kruger National Park and the Maasai Mara is four or five adults, while packs in Moremi and Selous Game Reserves contain eight or nine. However, larger packs have been observed and temporary aggregations of hundreds of individuals may have gathered in response to the seasonal migration of vast springbok herds in Southern Africa. Males and females have separate dominance hierarchies, with the latter usually being led by the oldest female. Males may be led by the oldest male, but these can be supplanted by younger specimens; thus, some packs may contain elderly male former pack leaders. The dominant pair typically monopolises breeding. The species differs from most other social carnivorans in that males remain in the natal pack, while females disperse (a pattern also found in primates such as gorillas, chimpanzees, and red colobuses). 

Furthermore, males in any given pack tend to outnumber females 3:1. Dispersing females join other packs and evict some of the resident females related to the other pack members, thus preventing inbreeding and allowing the evicted individuals to find new packs of their own and breed. Males rarely disperse, and when they do, they are invariably rejected by other packs already containing males. Although arguably the most social canid, the species lacks the elaborate facial expressions and body language found in the wolf, likely because of the African wild dog's less hierarchical social structure. Furthermore, while elaborate facial expressions are important for wolves in re-establishing bonds after long periods of separation from their family groups, they are not as necessary to African wild dogs, which remain together for much longer periods. The species does have an extensive vocal repertoire consisting of twittering, whining, yelping, squealing, whispering, barking, growling, gurling, rumbling, moaning and hooing.

African wild dog populations in East Africa appear to have no fixed breeding season, whereas those in Southern Africa usually breed during the April–July period. During estrus, the female is closely accompanied by a single male, which keeps other members of the same sex at bay.[26] The estrus period can last as long as 20 days. The copulatory tie characteristic of mating in most canids has been reported to be absent or very brief (less than one minute) in African wild dog, possibly an adaptation to the prevalence of larger predators in its environment. The gestation period lasts 69–73 days, with the interval between each pregnancy being 12–14 months typically. The African wild dog produces more pups than any other canid, with litters containing around six to 16 pups, with an average of 10, thus indicating that a single female can produce enough young to form a new pack every year. Because the amount of food necessary to feed more than two litters would be impossible to acquire by the average pack, breeding is strictly limited to the dominant female, which may kill the pups of subordinates. After giving birth, the mother stays close to the pups in the den, while the rest of the pack hunts. She typically drives away pack members approaching the pups until the latter are old enough to eat solid food at three to four weeks of age. The pups leave the den around the age of three weeks and are suckled outside. The pups are weaned at the age of five weeks, when they are fed regurgitated meat by the other pack members. By seven weeks, the pups begin to take on an adult appearance, with noticeable lengthening in the legs, muzzle, and ears. Once the pups reach the age of eight to 10 weeks, the pack abandons the den and the young follow the adults during hunts. The youngest pack members are permitted to eat first on kills, a privilege which ends once they become yearlings. African wild dogs have an average lifespan of about 10 to 11 years in the wild.

When separated from the pack, an African wild dog becomes depressed and can die as a result of broken heart syndrome.

23-5-2019 MANA POOLS, ZIMBABWE - BUSHVELD HELMETED GUINEA FOWL (Numida meleagris ssp. mitratus)

The helmeted guineafowl (Numida meleagris) is the best known of the guineafowl bird family, Numididae, and the only member of the genus Numida. It is native to Africa, mainly south of the Sahara, and has been widely introduced, as a domesticated species, into the West Indies, North America, Colombia, Brazil, Australia and Europe.

The helmeted guineafowl is a large, 53 to 58 cm (21 to 23 in) bird with a round body and small head. They weigh about 1.3 kg (2.9 lb). The body plumage is gray-black speckled with white. Like other guineafowl, this species has an unfeathered head, which in this species is decorated with a dull yellow or reddish bony knob, and bare skin with red, blue, or black hues. The wings are short and rounded, and the tail is likewise short. Various subspecies are proposed, differences in appearance being mostly a large variation in shape, size, and colour of the casque and facial wattles.

This is a gregarious species, forming flocks outside the breeding season typically of about 25 birds that also roost communally. Guineafowl are particularly well-suited to consuming massive quantities of ticks, which might otherwise spread Lyme disease. These birds are terrestrial, and prone to run rather than fly when alarmed. Like most gallinaceous birds, they have a short-lived, explosive flight and rely on gliding to cover extended distances. Helmeted guineafowl can walk 10 km and more in a day. Their bodies are well-suited for running and they are remarkably successful in maintaining dynamic stability over rough terrain at speed. They make loud harsh calls when disturbed.

23-5-2019 MANA POOLS, ZIMBABWE - EMERALD SPOTTED WOOD DOVE (Turtur chalcospilos)

The emerald-spotted wood dove or emerald-spotted dove (Turtur chalcospilos) is a bird of the family Columbidae, resident across eastern and southern Africa. It is a species of open drier deciduous woodland and second growth. It is absent from evergreen rainforests and semidesert areas.

Calling in woodland during autumn

The emerald-spotted wood dove is a small plump pigeon, typically 20 cm in length. Its back, hindneck, wings, and tail are pale grey-brown, and the folded wings have green metallic patches. There are blackish bands on the lower back and tail. The forehead, crown, and nape are bluish-grey, fading to pinkish-grey on the throat. The underparts are mauve-pink, becoming whiter on the belly.

The bill of this dove is blackish with a red base. The sexes are similar, but the female may be slightly duller than the male. The immature has duller green spots and buff fringes to the feathers. When flying, the black-billed wood dove is told from this species by its bright chestnut underwings.

22-5-2019 MANA POOLS, ZIMBABWE - WIRE TAILED SWALLOW (Hirundo smithii)

The wire-tailed swallow is a small bird with a glossy blue back, white underparts, and a chestnut-colored cap, named for its two long, thin tail feathers. It is a fast, aerial insectivore, often seen flying low over water and building its mud nest on vertical surfaces, including human-made structures like bridges and buildings. This species is widespread across sub-Saharan Africa and southern Asia and has a "least concern" conservation status globally. 

Physical characteristics

Size: Measures approximately 18 cm (7.1 in) long.

Plumage: Features glossy blue upperparts, a chestnut forehead and crown, and clean white underparts.

Tail: Distinguished by two very long, thin, wire-like filaments on its outer tail feathers. Females and juveniles have shorter or no "wires" and a duller cap.

Habitat and behavior

Habitat: Prefers open country, such as grasslands, wetlands, and cultivated areas, particularly near water.

Diet: An aerial insectivore that feeds on flying insects like flies, wasps, and termites.

Flight: A very fast flyer that often swoops low over water. 

Nesting and reproduction

Nest: Builds a neat, half-bowl-shaped nest from mud, which is placed on vertical surfaces. Nests are often found under cliff ledges or on man-made structures like bridges, buildings, and culverts.

Territorial: Nests are typically solitary and territorial, unlike some colonial swallow species.

Eggs and incubation: Lays a clutch of 2-4 eggs in Africa and up to 5 in Asia. The female primarily incubates the eggs.

Parental care: Both parents feed the chicks, with the female providing more food. 

Distribution and conservation

Distribution: Found in sub-Saharan Africa and southern Asia. Some populations are resident, while others migrate seasonally.

Conservation status: Globally listed as "least concern" by the IUCN, although some regional statuses may vary.

Threats: The introduction of man-made nest sites has, in fact, benefited this species. 

23-5-2019 MANA POOLS, ZIMBABWE - COMMON DWARF MONGOOSE (Helogale parvula)

The common dwarf mongoose (Helogale parvula) is a mongoose species native to Angola, northern Botswana, northern Namibia, KwaZulu-Natal in South Africa, Zambia and East Africa. It is part of the genus Helogale, along with the Ethiopian dwarf mongoose.

The common dwarf mongoose has soft fur ranging from yellowish red to very dark brown. It has a large pointed head, small ears, a long tail, short limbs and long claws. With a body length of 16–23 cm (6.3–9.1 in) and a weight of 213–341 g (7.5–12.0 oz), it is Africa's smallest member of the order Carnivora.

The common dwarf mongoose ranges from East to southern Central Africa, from Eritrea and Ethiopia to the provinces of Limpopo and Mpumalanga in the Republic of South Africa. It inhabits primarily dry grassland, open forests and bushland up to an elevation of 2,000 m (6,600 ft). It is especially common in areas with many termite mounds, its favorite sleeping place. It avoids dense forests and deserts.

The main predators of dwarf mongoose are predatory birds such as raptors and marabou storks, reptiles such as snakes and monitor lizards, and other carnivorous mammals such as jackals and larger mongooses.

A mutualistic relationship has evolved between the dwarf mongoose and hornbills, in which hornbills seek out the mongooses in order for the two species to forage together, and to warn each other of nearby birds of prey and other predators.

It is a social animal, with an average group size of twelve individuals,but larger packs can exceed thirty members. Packs are organized around a strict hierarchy, with females holding higher positions than males within each age class. Each pack is structured around a single breeding pair, the breeding female of which holds the highest social position while her mate holds the second highest. Younger members and immigrant individuals do not typically reproduce, but instead care for and feed juveniles. Other females may reproduce during good conditions, but their litters rarely survive to adulthood. The breeding pair of a dwarf mongoose colony is given priority access to food and protection from subordinate members, and rarely has to defend against predators. The breeding male is most often responsible for suppressing reproduction among other colony members by confronting them directly when this is attempted, typically with a low-intensity threat posture, which causes the pair to cease their attempted reproduction and retreat. The female of the pair often grooms the alpha male afterwards as an appeasement behavior.

Dispersal and the funding of new packs are relatively rare, and group splits occur most often when the dominant female dies. Non-breeders occasionally transfer between different packs, typically at their second or third year of age and during the rain season, which can result in their obtaining a shorter "queue" for becoming part of the breeding pair of the new pack.

Dwarf mongooses tend to breed during the wet season, between November and May, where the breeding female may produce up to three litters, containing an average of four pups each after a gestation period of 49 to 53 days. The pups nurse for a period of 45 days, during which they may be nursed by subordinate females. Juveniles begin foraging alongside adults at around six weeks of age, and reach sexual maturity at three years of life. Their maximum lifespan is around 18 years.

The primary diet of the common dwarf mongoose consists of invertebrates, chiefly insects such as beetle larvae, termites, grasshoppers and crickets, alongside spiders and scorpions. Secondary food sources include small vertebrates, eggs, and fruit.
