23-5-2019 MANA POOLS, ZIMBABWE - AFRICAN YELLOW PANSY BUTTERFLY (Junonia hierta ssp. cebrene)


The African Yellow Pansy (\(Junonia\) \(hierta\)) is a butterfly with a bright yellow upperside and black markings, found in open habitats across Africa, Arabia, and the Indian subcontinent. It has a low, fast flight and feeds on a variety of herbs as a larva, while adults extract nutrients from mud, rotting fruit, and animal dung. It is also known for being very common and is not considered endangered globally or in South Africa. 

Key facts Scientific Name: Junonia hiertaFamily: Nymphalidae (Brush-footed Butterflies)Appearance:Males: Bright yellow upperside with black markings and sometimes a purple or blue spot.Females: Similar colors but duller and often with different markings, including a black spot on the hindwing.

23-5-2019 MANA POOLS, ZIMBABWE - WHITE BROWED SPARROW WEAVER (Plocepasser mahili)


The white-browed sparrow-weaver (Plocepasser mahali) is a predominantly brown, sparrow-sized bird found throughout central and north-central southern Africa. It is found in groups of two to eleven individuals consisting of one breeding pair and other non-reproductive individuals.

The white-browed sparrow-weaver is found in greatest numbers in north-central southern Africa. While this species most densely populates dry regions with woodland or wooded grassland at northern South Africa, its range includes Botswana, northern and central Namibia, and western Zimbabwe. It is seen very often in South Luangwa National Park, Zambia and southern Malawi. Populations may be found as far north as Ethiopia. Populations are sedentary.

This species nests in colonies along thornveld and scrubby, dry riverbanks.

23-5-2019 MANA POOLS, ZIMBABWE - TAWNY EAGLE (Aquila rapax)


The Tawny Eagle (Aquila rapax) is a large bird of prey, belonging to the family Accipitridae. It is characterized by heavily feathered legs, indicative of its membership in the subfamily Aquilinae, or booted eagles. Exhibiting a polymorphic plumage, the Tawny Eagle's coloration ranges from dark grey-brown to rufous-tawny, with a strong and bold bill, well-proportioned frame, and fierce countenance. This eagle is known for its opportunistic feeding habits, engaging in both active predation and scavenging.

The Tawny Eagle can be identified by its long neck, large bill without a deep gape, and moderately long wings with pronounced "fingers." Its tail is shortish and square-ended, resembling that of a vulture. Adults may have variably colored eyes from yellow to pale brown, with a yellow cere and feet at all ages. The species is polymorphic, with individuals varying in plumage from dark brown to rufous and buffish-yellow.


Tawny Eagles favor open dry habitats such as semideserts, deserts steppes, or savanna plains. They are seldom found in areas completely devoid of trees, as they require perches for hunting and nesting.

The Tawny Eagle has a discontinuous breeding range across much of the African continent and the Indian subcontinent, with rare residency in the southern Middle East.

The Tawny Eagle is largely sedentary and non-migratory, though it may exhibit nomadic tendencies in response to environmental conditions. It spends much of its day perched, taking flight intermittently to hunt or scavenge.

Generally silent, the Tawny Eagle may occasionally vocalize with a harsh, hollow-sounding bark. Males are more vocal, especially during displays of courtship.


Tawny Eagles are resident breeders, laying one to three eggs in a stick nest typically located in the crown of a tree. They often pair for life and are territorial.

The Tawny Eagle can be confused with the Steppe Eagle, but differs in size, gape, and plumage. It also shares its range with various other booted eagles, but can be distinguished by its unique tail shape, bill size, and flight profile.

The Tawny Eagle has a highly variable diet, including live prey such as small to medium-sized mammals, birds, and reptiles, as well as carrion. It is also known for kleptoparasitism, stealing food from other raptors.

The Tawny Eagle is currently listed as Vulnerable on the IUCN Red List. Its population has declined significantly due to habitat loss, persecution, and other anthropogenic factors.

23-5-2019 MANA POOLS, ZIMBABWE - SPOTTED BUSH SNAKE (Philothamnus semivariegatus)


Philothamnus semivariegatus, commonly known as the spotted bush snake is a species of non-venomous colubrid snake, endemic to Africa.

P. semivariegatus is distributed from South Africa northward to Sudan, Uganda and from Guinea eastward to Tanzania and sited at Nigeria.

The colour is bright green with black speckles. Average snout to vent length (SVL) is 60–90 cm (24–35 in).


Spotted bush snakes are mostly found in trees in bush and forest areas, where they hunt lizards and treefrogs. They are also known to devour chameleons and dwarfs. They are excellent climbers and swimmers, have very good eyesight, and are highly alert snakes. They are not territorial, and will roam great distances in search for food. Spotted bush snakes are very common and completely harmless. They are well camouflaged, naturally very nervous, and quick to escape from any potential threat. As such, suburban sightings are rare.


They can be very difficult to keep in captivity, being very nervous and reluctant to feed on anything but sympatric gecko species, but they are occasionally kept and bred successfully.

Females can lay between 3 and 12 elongate eggs every summer, and each hatchling is about 25 cm (9.8 in) in total length (including tail).

23-5-2019 MANA POOLS, ZIMBABWE - AFRICAN SAVANNA ELEPHANT (Loxodonta Africana)


Mana Pools is a national park in Zimbabwe famous for its large elephant population, and it is one of the few places where you can observe elephants on foot. A unique behavior exhibited by some bull elephants here is standing on their hind legs to reach food in trees, a skill learned during past droughts. Some of these elephants, such as the famous bull Boswell, are well-known and have become iconic figures.  
This video shows the behavior of elephants in Mana Pools, including standing on their hind legs to reach food:


Iconic behavior: Bull elephants at Mana Pools have developed the habit of standing on their hind legs to eat from trees, a behavior that allows them to access food high up on branches, especially during the dry season. 

Famous elephants: Elephants like Boswell and Tusker are well-known for this behavior and have become something of celebrities, with Boswell even being tracked by rangers. 

Unique experience: Mana Pools is a UNESCO World Heritage Site and offers a remote safari experience where you can walk among the wildlife, providing very close and intimate encounters with elephants and other animals. 

Elephant population: The park is home to one of the largest concentrations of elephants in the country, with more than 12,000 elephants inhabiting the area. 

Ecological impact: The presence of these large elephant herds has significantly altered the landscape, with their feeding habits shaping the environment. 


The sanctuary, one of the only two pockets of nyala in the country, is also home to 16 000 buffalo and more than 12 000 elephant - Zimbabwe's largest concentration after Hwange. Many female elephants in the region do not have tusks and are much more aggressive than those with tusks.


The African bush elephant (Loxodonta africana), also known as the African savanna elephant, is a species of elephant native to sub-Saharan Africa. It is one of three extant elephant species and, along with the African forest elephant, one of two extant species of African elephant. It is the largest living terrestrial animal, with fully grown bulls reaching an average shoulder height of 3.04–3.36 metres (10.0–11.0 ft) and a body mass of 5.2–6.9 tonnes (5.7–7.6 short tons); the largest recorded specimen had a shoulder height of 3.96 metres (13.0 ft) and an estimated body mass of 10.4 tonnes (11.5 short tons). The African bush elephant is characterised by its long prehensile trunk with two finger-like processes; a convex back; large ears which help reduce body heat; and sturdy tusks that are noticeably curved. The skin is grey with scanty hairs, and bending cracks which support thermoregulation by retaining water.


The African bush elephant inhabits a variety of habitats such as forests, grasslands, woodlands, wetlands and agricultural land. It is a mixed herbivore feeding mostly on grasses, creepers, herbs, leaves, and bark. The average adult consumes about 150 kg (330 lb) of vegetation and 230 L (51 imp gal; 61 US gal) of water each day. A social animal, the African bush elephant often travels in herds composed of cows and their offspring. Adult bulls usually live alone or in small bachelor groups. During the mating season, males go through a process called musth, a period of high testosterone levels and heightened aggression. For females, the menstrual cycle lasts three to four months, and gestation around 22 months, the longest of any mammal.


Since 2021, the African bush elephant has been listed as Endangered on the IUCN Red List. It is threatened foremost by habitat destruction, and in parts of its range also by poaching for meat and ivory. Between 2003 and 2015, the illegal killing of 14,606 African bush elephants was reported by rangers across 29 range countries. Chad is a major transit country for smuggling of ivory in West Africa. This trend was curtailed by raising penalties for poaching and improving law enforcement. Poaching of the elephant has dated back to the 1970s and 80s, which were considered the largest killings in history. In human culture, elephants have been extensively featured in literature, folklore and media, and are most valued for their large tusks in many places.


The African bush elephant is the largest and heaviest living land animal. Under optimal conditions where individuals are capable of reaching full growth potential, fully grown mature males are about 3.20 m (10.5 ft) tall at the shoulder and weigh 6.0 t (6.6 short tons) on average (with 90% of fully grown males under optimal conditions being between 3.04–3.36 m (10.0–11.0 ft) and 5.2–6.9 t (5.7–7.6 short tons)). Mature fully grown females are smaller at about 2.60 m (8 ft 6 in) tall at the shoulder and 3.0 t (3.3 short tons) in weight on average under optimal growth conditions (with 90% of fully grown females ranging between 2.47–2.73 m (8 ft 1 in – 8 ft 11 in) and 2.6–3.5 t (2.9–3.9 short tons) in optimal conditions).[17][18][19][20] The maximum recorded shoulder height of an adult bull is 3.96 m (13.0 ft), with this individual having an estimated weight of 10.4 t (11.5 short tons). Another individual with a similar weight of more than 10 t (9.8 long tons; 11 short tons) was found in Kenya in 2025, making it one of the largest elephants ever recorded. Elephants attain their maximum stature when they complete the fusion of long-bone epiphyses, occurring in males around the age of 40 and females around 25 years of age.


Both sexes have large, curved, maxillary incisors known as tusks that continue growing throughout their lives. In the wild, a large percentage of elephants experience a tusk fracture, although this is more prevalent in captivity. A tusk fracture of any sort usually results in serious infections, as the pulp is exposed to the elements. The tusks erupt when they are 1–3 years old. Tusks grow from deciduous teeth known as tushes that develop in the upper jaw and consist of a crown, root and pulpal cavity, which are completely formed soon after birth. Tushes reach a length of 5 cm (2.0 in). They are composed of dentin and coated with a thin layer of cementum. Their tips bear a conical layer of enamel that is usually worn off when the elephant is five years old. Tusks of bulls grow faster than tusks of cows. Mean weight of tusks at the age of 60 years is 109 kg (240 lb) in bulls and 17.7 kg (39 lb) in cows. The longest known tusk of an African bush elephant measured 3.51 m (11.5 ft) and weighed 117 kg (258 lb).


The African bush elephant occurs in sub-Saharan Africa which includes Uganda, Kenya, Tanzania, Botswana, Zimbabwe, Namibia, Zambia, Angola, Malawi, Mali, Rwanda, Mozambique and South Africa. It moves between a variety of habitats, including subtropical and temperate forests, dry and seasonally flooded grasslands, woodlands, wetlands, and agricultural land from sea level to mountain slopes. In Mali and Namibia, it also inhabits desert and semi-desert areas.


Populations of African bush elephants are increasing in some areas such as the Kruger National Park, where an annual growth of 4.2% was recorded between 2003 and 2015. There are estimated to be at least 17,000 elephants in the park's vicinity, as of 2015–the most of any area in South Africa. The increase in population occurred after the discontinuation of culling in the mid-1990s. This large elephant population is considered a problem to both the environment and its creatures. As such, with the use of natural processes, conservationists aim to control the ever-growing population. In other places in southern Africa, the elephant population continues to increase. Botswana in particular hosts more African bush elephants than any other country, at 130,000. In a 2019 study, populations were found to be steady, though the authors also noted an unusual increase in carcasses, possibly due to a new wave of poaching which was uncommon at the time.

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.

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.
