20-4-2018 OKAVANGO DELTA, BOTSWANA - STRIPED KINGFISHER (Halcyon chelicuti) COURTESY OF MRS VALERIE FISHER


The Striped Kingfisher, known scientifically as Halcyon chelicuti, is a member of the tree kingfisher subfamily. It is a small, robust bird, with a general length ranging from 16 to 18 cm. The upper parts of the adult are predominantly greyish brown, while the lower back, secondary flight feathers, and tail boast a striking metallic blue, which is particularly visible in flight. The underparts are off-white, with varying degrees of buff and brown streaking across the subspecies.

When perched, the Striped Kingfisher may appear rather inconspicuous, but its flight reveals a white patch at the base of the primary flight feathers and a black border along the wing linings. Males can be identified by a black bar at the base of the primaries. The head is streaked dark brown, with a buffy grey or brownish background depending on the sex. A black line runs through the eyes and around the back of the neck, sitting above a white collar. The bill is blackish above and reddish-orange below, with the lower mandible being dull red in juveniles.


The Striped Kingfisher favors woodlands, thorn scrub, dry bush, and open savannas, but it tends to avoid densely forested areas, intensive farmlands, and extreme deserts.

This species is found throughout Sub-Saharan Africa, with two subspecies: H. c. chelicuti occupying most of the range, and H. c. eremogiton residing in the northern desert regions from central Mali to eastern Sudan.


Highly territorial, the Striped Kingfisher defends an area that may encompass up to three hectares and contain around 100 tall trees. It is known to chase away intruders, including other kingfishers, shrikes, doves, and rollers. The bird surveys its territory from a treetop, singing from before dawn until after midday.

The call of the Striped Kingfisher is a high-pitched, piercing "cheer-cherrrrrr" or a far-carrying "KEW, kerrrrrrrrr," with the latter featuring a descending trill. This call is often part of a dusk display involving wing-opening.

19-4-2018 NXABEGA LODGE OKAVANGO DELTA, BOTSWANA - SOUTHERN GREY HEADED KINGFISHER (Halcyon leucocephala ssp pallidiventris) COURTESY OF MRS VALERIE FISHER


The Southern Grey-headed Kingfisher, Halcyon leucocephala, presents a striking figure with its pale grey head, black mantle, and a vivid blue rump. Its wings and tail share this blue brilliance, while the chestnut underparts add a warm contrast. The beak, long and sharp, is a notable red. This bird averages 21 cm in length, a size that allows it to maneuver with agility in its preferred habitats.

When identifying the Grey-headed Kingfisher, look for the combination of its grey head and chestnut belly, which distinguishes it from similar species. The subspecies H. l. pallidiventris has a darker grey head and paler chestnut underparts. The bird's bright blue rump, wings, and tail are also key identification features.

This kingfisher favors woodlands, scrub, and cultivated areas, and can be found at altitudes up to 2,200 meters. It is often seen near water, though it does not rely on aquatic environments.

20-8-2018 MONTE CORONA, VALENCIA - MOORISH GECKO (Tarentola mauritanica)


Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas (in Montevideo, Buenos Aires and California). A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.
The species was first described by Carl Linnaeus in 1758. It is also known as moorish gecko, crocodile gecko, European common gecko, and, regionally, as osga (in Portuguese), salamanquesa (in Spanish) and dragó (in Catalan).

22-8-2018 EL SALER, VALENCIA - DROMEDARY CAMEL (Camelus dromedarius)


Camels have a slow growth rate and reach sexual maturity slower than sheep or goat. The age of sexual maturity varies geographically and depends on the individual, as does the reproductive period. Both sexes might mature by three to five years of age, though successful breeding could take longer. Camels are described as atypical seasonal breeders; they exhibit spermatogenesis throughout the whole year with a reduction in spermatogenesis during the nonbreeding season compared to that in the breeding season (Zayed et al., 1995). The breeding season in Egypt is during spring; the spring months. Mating occurs once a year, and peaks in the rainy season. The mating season lasts three to five months, but may last a year for older animals.


Its range included hot, arid regions of northern Africa, Ethiopia, the Near East, and western and central Asia. The dromedary typically thrives in areas with a long dry season and a short wet season. They are sensitive to cold and humidity, though some breeds can thrive in humid conditions.

22-8-2018 RACO DE OLLA, VALENCIA - LITTLE RINGED PLOVER (Charadrius dubius)


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

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


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

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

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


The call of the Little Ringed Plover is a distinctive sound, contributing to the rich tapestry of bird songs in its habitat.

During the breeding season, these birds exhibit a fascinating mating ritual where the male bird may be observed tapping the cloaca of the female.

While similar in appearance to the larger Ringed Plover, the Little Ringed Plover can be differentiated by its leg colour, head pattern, and the conspicuous yellow eye-ring.

The diet of the Little Ringed Plover consists of insects and worms, which it diligently searches for in muddy areas.

22-8-2018 EL PALMAR, VALENCIA - EUROPEAN SAND MARTIN (Riparia riparia)


The Sand Martin, known as the Bank Swallow in the Americas, is a diminutive and agile bird, a member of the swallow family. Its upper parts are cloaked in a modest brown, while its underparts are a stark white, bisected by a slender brown band across the breast. The bird's bill is a deep black, and its legs are a shade of brown. Juveniles can be distinguished by the rufous fringes on their coverts and the edges of their secondary feathers.

With a length of 12-14 cm and a wingspan of 25-33 cm, the Sand Martin is a small bird that can be readily identified by its brown back, white throat, and the distinctive narrow brown band on its breast. Its flight is characterized by rapid, jerky movements that set it apart from other swallows.

Sand Martins are commonly found near large bodies of water, such as rivers, lakes, or oceans, where they can be seen darting gracefully over the water's surface.


This migratory passerine has a broad summer range that spans Europe, the Mediterranean, and across the Palearctic to the Pacific Ocean. It is also a Holarctic species present in North America. During the winter months, it retreats to the warmer climates of eastern and southern Africa, South America, and the Indian Subcontinent.

Sand Martins are social birds, often nesting in large colonies where hundreds of pairs may reside in close proximity. They are early migrants, arriving at breeding grounds before many other swallows and departing by the end of September. Their flight is a delightful spectacle, with swift and erratic movements as they hunt for insects over water bodies.

The Sand Martin's vocalizations include a continuous twittering song while in flight, which softens to a conversational murmur when perched. They also emit a harsh alarm call in response to potential predators.


These birds exhibit a strong preference for nesting in sandy hills or loess banks, where they excavate tunnels to lay their eggs. The breeding season typically sees them produce two broods, with each clutch consisting of four to five pristine white eggs.

The Sand Martin can be confused with the Banded Martin of sub-Saharan Africa, but the latter is only present in the Sand Martin's wintering grounds.

Their diet primarily consists of small insects, particularly gnats and other flies that have aquatic larval stages.

The Sand Martin is globally recognized as a species of Least Concern by the IUCN, although it is noted that their numbers are decreasing. Some populations are under threat due to habitat loss and are protected under national and local conservation laws. In Canada, for instance, the species is listed as Threatened due to a significant population decline.

22-8-2018 ALBUFERA, VALENCIA - WHISKERED TERN (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.

22-8-2018 ALBUFERA, VALENCIA - SQUACCO HERON (Ardeola ralloides)


The Squacco Heron is a tawny buff brown heron with a streaked head and back, and in breeding a black and white mane.
Adult: The adult nonbreeding Squacco Heron has a head that is finely streaked in black, brown, and grey, forming a modest crown but no elongated plumes in nonbreeding season. The relatively large and powerful bill is pale green yellow with a black tip and top. The lores are dull yellow green. The irises are yellow. The hind neck, like the head, is finely streaked in black, brown and grey. The upperparts are buff brown with slight tawny tinge. The wings are white and are mostly concealed at rest by the back plumes. The plumes are shorter than in the breeding season. The rump and tail are white. Foreneck and breast are bright buff coarsely streaked in dark brown. The remaining underparts are white. The relatively short legs and the feet are dull yellow green.


In breeding plumage, the upper parts become brighter and deeper. The crown is a mane of yellow buff or straw-colored feathers. The crown feathers are slightly elongated (1-5 cm) and are bordered with black. Several very elongated feathers (13-14 cm long) occur on the back of the crown. These are white bordered with black, and extend over the upper back. The lores are green or blue. The lower neck and back plumes are golden to cinnamon buff. The foreneck and breast are red gold. During courtship, the bill becomes bright blue except for the dark to black tip. The lores turn briefly blue before reverting via emerald to yellow green. The irises in courtship are richer yellow. The back is pink brown, with longest back feathers being golden and drooping over the wings. The legs are bright red in courtship, fading to pink after pairing. The other soft parts colors return to normal after the eggs are laid.

Variation: The sexes are alike. Geographic variation is not recognized taxonomically. South and central African birds were once considered recognized as the subspecies paludivaga.

22-8-2018 ALBUFERA, 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.

22-8-2018 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)


Grey Herons are unmistakeable – tall, with long legs, a long beak and grey, black and white feathering. They can stand with their neck stretched out, looking for food, or hunched down with their neck bent over their chest.

The Grey Heron is a distinctive species with grey, black, and white plumage. It is often seen along rivers or lake margins, or standing in flooded fields.

In flight their large size, impressive wingspan, long legs, and folded neck give them an unmistakable silhouette. Largely silent away from colonies, flight is sometimes accompanied by a harsh ‘kraank’ call.

Grey Herons gather to nest in treetop sites called heronries, some of which have been occupied for many decades. These have been monitored in the UK since 1928 through the Heronries Census. Overall the UK's breeding population has increased, with numbers peaking in the early 2000, but with some more recent declines.

16-4-2018 CHOBE NATIONAL PARK, BOTSWANA - AFRICAN LION (Panthera leo) COURTESY OF MRS VALERIE FISHER


The lion (Panthera leo) is a large cat of the genus Panthera, native to Africa and India. It has a muscular, broad-chested body; a short, rounded head; round ears; and a dark, hairy tuft at the tip of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is a social species, forming groups called prides. A lion's pride consists of a few adult males, related females, and cubs. Groups of female lions usually hunt together, preying mostly on medium-sized and large ungulates. The lion is an apex and keystone predator.

The lion inhabits grasslands, savannahs, and shrublands. It is usually more diurnal than other wild cats, but when persecuted, it adapts to being active at night and at twilight. During the Neolithic period, the lion ranged throughout Africa and Eurasia, from Southeast Europe to India, but it has been reduced to fragmented populations in sub-Saharan Africa and one population in western India. It has been listed as Vulnerable on the IUCN Red List since 1996 because populations in African countries have declined by about 43% since the early 1990s. Lion populations are untenable outside designated protected areas. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are the greatest causes for concern.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - BLACK HEADED HERON (Ardea melanocephala) COURTESY OF MRS VALERIE FISHER


The black-headed heron, Ardea melanocephala, is a stately wading bird from the heron family Ardeidae. It stands at an impressive 85 cm in height, with a wingspan stretching to 150 cm. Its plumage is predominantly grey, with a darker shade above and a paler grey below. The bird is named for its striking black head, which contrasts with its grey body. A powerful dusky bill completes its commanding appearance.

When identifying the black-headed heron, look for its large size, nearly matching that of the grey heron. Its black head and neck, along with the grey body, are key distinguishing features. In flight, observe the slow wingbeats and the retracted neck, a common trait among herons. The white underwing coverts are particularly noticeable when the bird is airborne.

This heron is commonly found in a variety of wetland habitats throughout sub-Saharan Africa and Madagascar. It is comfortable in both shallow water and dry grasslands.

The black-headed heron is widespread across much of sub-Saharan Africa and Madagascar. It is mainly a resident species, though some individuals from West Africa may migrate northward during the rainy season.

The black-headed heron exhibits typical heron behavior, often seen feeding in shallow waters or stalking prey in grasslands. It is known to stand motionless, waiting for prey, or to slowly stalk its victim with stealth and precision.

The vocalizations of the black-headed heron include a distinctive loud croaking, often heard during dusk at heronries.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - AFRICAN SAVANNA ELEPHANT (Loxodonta Africana) COURTESY OF MRS VALERIE FISHER


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.

18-4-2018 CHOBE NATIONAL PARK, BOTSWANA - KORI BUSTARD (Ardeotis kori) COURTESY OF MRS VALERIE FISHER


The kori bustard (Ardeotis kori) stands as the largest flying bird native to Africa, a member of the bustard family Otididae. Males are particularly hefty, possibly the heaviest living animal capable of flight. The species exhibits sexual dimorphism, with males significantly outweighing females. Their plumage is cryptically colored, blending into their savanna habitats with a mottled pattern of grey, brown, black, and white.

Adult kori bustards are distinguished by their large size, heavy build, and a distinctive black crest on their heads. Their eyes are ringed with white, and they possess a black collar at the base of the hind-neck that extends onto the sides of the breast. The legs are long and yellowish, and the bill is light greenish horn-colored. Juveniles resemble females but are browner with more spotting on the mantle.

Kori bustards favor open grassy areas with sandy soil, short grass, and occasional trees or bushes for cover. They are found in plains, arid plateaus, grasslands, lightly wooded savannas, and semi-deserts, avoiding densely wooded areas.

This species is widespread across southern Africa, with populations extending from Botswana and Namibia to South Africa, Mozambique, and parts of East Africa, including Ethiopia, Kenya, and Tanzania.


Kori bustards are primarily terrestrial, spending much of their time foraging on foot. They exhibit cautious behavior, often fleeing on foot before resorting to flight. They are known for their slow, deliberate walk and can be solitary or found in groups, especially around abundant food sources.

The kori bustard is generally quiet but can produce a deep, booming mating call, a loud growling bark when alarmed, and a snapping bill sound during close encounters.

Breeding is influenced by rainfall, with males engaging in lek mating, displaying at regular sites to attract females. Females lay eggs on the ground in shallow hollows, often near trees or shrubs, and raise the young without male assistance.


The kori bustard can be confused with other large bustards like Denham's and Ludwig's bustards but can be differentiated by its greyer appearance and lack of white upperwing markings in flight.

An opportunistic omnivore, the kori bustard's diet includes insects, small vertebrates, and plant material. They forage by walking slowly and picking at the ground, often following herds of ungulates to catch prey disturbed by their movement.

The kori bustard is classified as Near Threatened due to habitat destruction, hunting, and collisions with power lines. While they can be locally common in protected areas, their populations are generally scarce outside these regions.

15-4-2018 CHOBE RIVER, NAMIBIA - AFRICAN FISH EAGLE (Haliaeetus vocifer) COURTESY OF MRS VALERIE FISHER


The African fish eagle, or African sea eagle, is a majestic bird of prey that graces the skies of sub-Saharan Africa. It is a symbol of national pride, being the national bird of Malawi, Namibia, Zambia, and Zimbabwe. This raptor is known for its striking appearance, with a mostly brown body contrasted by a snow-white head, breast, and tail. The face is featherless and a vivid yellow, matching the color of its formidable, hooked beak, tipped in black. The African fish eagle's eyes are a deep, dark brown, and its powerful black wings carry it effortlessly over open waters.

Adult African fish eagles are unmistakable with their white heads and chests, brown bodies, and large black wings. Females are larger than males, with wingspans reaching up to 2.4 meters, compared to the 2-meter span of males. Juveniles can be identified by their overall brown plumage and paler eyes. The species exhibits sexual dimorphism, with females being heavier, weighing between 3.2 to 3.6 kilograms, while males weigh between 2.0 to 2.5 kilograms.

These eagles are typically found near freshwater lakes, reservoirs, rivers, and sometimes along coastlines at river mouths or lagoons. They thrive in a variety of habitats, including grasslands, swamps, marshes, tropical rainforests, and even desert-bordering coastlines.

The African fish eagle is indigenous to sub-Saharan Africa, with a presence in most areas south of the Sahara Desert. It is commonly seen in regions like the Orange River, the Okavango Delta, and around Lake Victoria and other large Rift Valley lakes.

15-4-2018 CHOBE RIVER, NAMIBIA - NILE MONITOR (Varanus niloticus) COURTESY OF MRS VALERIE FISHER


The Nile monitor (Varanus niloticus) is a large member of the monitor family (Varanidae) found throughout most of Sub-Saharan Africa and along the Nile, with invasive populations in North America. The population in West African forests and savannahs is sometimes recognized as a separate species, the West African Nile monitor (V. stellatus). It is one of the largest lizards in the world reaching and even surpassing the perentie by size. Other common names include the African small-grain lizard, as well as iguana and various forms derived from it, such as guana, water leguaan or river leguaan (leguan, leguaan, and likkewaan mean monitor lizard in South African English, and can be used interchangeably). A feral population of the lizards, descended from escaped or intentionally released pets, has become established in several locations in Florida.

14-4-2018 CHOBE RIVER, NAMIBIA - SOUTHERN RED BISHOP (Euplectes orix) COURTESY OF MRS VALERIE FISHER


The Southern Red Bishop (Euplectes orix) is a vibrant, small passerine bird, a member of the weaver family Ploceidae. It is known for its striking sexual dimorphism, with breeding males adorned in a fiery red and black plumage, while females and non-breeding males display a more subdued, streaky brown appearance.
Breeding males are unmistakable with their rich red and black coloration. They have a black face, throat, and belly, with the rest of the body a brilliant red, except for the brown wings and tail. Females and non-breeding males are paler and streaked brown, with the females being slightly smaller in size. The species is characterized by a thick conical bill, ideal for seed consumption.

The Southern Red Bishop thrives in wetlands and grasslands within Africa south of the Equator. It has a preference for areas near water, such as reeds and sedges, and can also be found in agricultural landscapes like sugar cane fields.

This species is widely distributed across the southern and eastern regions of Africa, ranging from South Africa to Angola, and extending to parts of the Democratic Republic of Congo, Zambia, Uganda, Nigeria, and Kenya. It avoids arid zones such as the Namib Desert and Kalahari.

The Southern Red Bishop is a sociable bird, often seen in flocks and nesting in colonies. It is polygynous, with males courting multiple females by constructing several nests and performing elaborate display flights. Its diet consists mainly of seeds, supplemented by insects.

20-8-2018 VILLALONGA RESERVOIR, VALENCIA - LITTLE EGRET (Egretta garzetta)


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

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


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

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

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

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


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

The Little Egret can be confused with other white egrets, particularly the Snowy Egret, which shares some of its New World range. However, the Little Egret is larger and has more varied foraging strategies.

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

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

20-8-2018 VILLALONGA RESERVOIR, VALENCIA - GREEN SANDPIPER (Tringa ochropus)


The Green Sandpiper, Tringa ochropus, is a small wader, or shorebird, with a somewhat plump appearance. It boasts a dark greenish-brown back and wings, complemented by a greyish head and breast. The underparts are predominantly white, with the back featuring white spots that vary in extent depending on the season and age of the bird. The legs and short bill are a matching dark green, creating a harmonious color palette for this avian species.

When observing the Green Sandpiper, look for its distinctive flight pattern, which reveals dark wings above and below, punctuated by a striking white rump. This feature is a reliable identifier, setting it apart from its close relative, the slightly smaller Solitary Sandpiper of North America. Additionally, the Green Sandpiper's white-spotted back is most pronounced in breeding adults and less so in winter and juvenile plumage.

The Green Sandpiper is a freshwater aficionado, often found in more confined spaces than other waders, which typically prefer open vistas. It thrives in a variety of freshwater habitats, avoiding the more gregarious nature of some wader congregations.


This bird breeds across subarctic Europe and extends its range east across the Palearctic. It is migratory, seeking winter respite in southern Europe, the Indian Subcontinent, Southeast Asia, and tropical Africa.

The Green Sandpiper is not known for its sociability, as it is rarely seen in large groups. It prefers to forage alone, methodically picking small invertebrate prey from the mud along the edges of ponds and streams.

In flight, the Green Sandpiper emits a characteristic three-note whistle, which can be heard over the quiet waters it frequents.

A unique nester among waders, the Green Sandpiper lays 2 to 4 eggs in the abandoned arboreal nests of other bird species, such as the Fieldfare. The eggs incubate for approximately three weeks before hatching.

The diet of the Green Sandpiper consists of small invertebrates, which it diligently collects from the muddy edges of its freshwater habitat.

The IUCN classifies the Green Sandpiper as Least Concern, indicating a stable global population. It is protected under the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), ensuring concerted efforts for its conservation.

20-8-2018 POTRIES, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)


The Mallard, or wild duck (Anas platyrhynchos), is a familiar and widespread dabbling duck with a presence across temperate and subtropical regions of the Americas, Eurasia, and North Africa. It has also been introduced to parts of the Southern Hemisphere. The male is renowned for its iridescent green head and white collar, while the female sports a brown-speckled plumage. Both sexes boast a speculum—a patch of feathers with iridescent purple or blue hues bordered by white. The Mallard's length ranges from 50 to 65 cm, with a wingspan of 81 to 98 cm, and it typically weighs between 0.7 and 1.6 kg.

Males during the breeding season are unmistakable with their glossy green heads, white collars, and purple-tinged brown breasts. Females are mottled brown with buff cheeks and an eye-stripe. Both sexes have the distinctive speculum on their wings. The male's bill is yellowish-orange tipped with black, while the female's is darker, ranging from black to mottled orange and brown.

Mallards are found in a variety of wetlands, including parks, small ponds, rivers, lakes, and estuaries. They prefer water depths less than 0.9 meters and are drawn to areas with aquatic vegetation.

20-8-2018 MONTE CORONA, VALENCIA - SARDINIAN WARBLER (FEMALE) (Sylvia melanocephala)


The Sardinian warbler, Curruca melanocephala, presents itself as a charming and distinctive bird of the Mediterranean. The males are adorned with a sleek grey back and pristine whitish underparts, crowned with a striking black head, a pure white throat, and captivating red eyes. The females, on the other hand, exhibit a more subdued palette, with brown upperparts and buff underparts, complemented by a subtle grey head.

When attempting to identify the Sardinian warbler, look for the male's black head and red eyes, which contrast with the white throat and grey back. Females can be recognized by their brown and buff coloration with a greyish head. The variability in plumage, including the presence or absence of a reddish hue, can be a helpful clue in distinguishing between subspecies.

This typical warbler favors open landscapes and cultivated areas, where it can find bushes suitable for nesting. Its preference for such environments makes it a familiar sight in the Mediterranean countryside.

The Sardinian warbler is a resident of the southernmost regions of Europe, extending its range into Asia in Turkey and the eastern Mediterranean. While not extensively migratory, some individuals do venture to North Africa for the winter, and the species has been known to appear as a vagrant as far as Great Britain.

20-8-2018 MONTE CORONA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a member of the sparrow family Passeridae. This small bird typically measures around 16 cm (6.3 in) in length and weighs between 24–39.5 g (0.85–1.39 oz). The species exhibits sexual dimorphism, with females and young birds displaying pale brown and grey plumage, while males are characterized by more vibrant black, white, and brown markings.
Males can be identified by their bright black, white, and brown markings, with a distinctive black bib, white cheeks, and a grey crown. Females lack the striking head patterns of males and are predominantly buffish with softer coloration. Juveniles resemble adult females but are generally paler with less defined markings.

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

Native to Europe, the Mediterranean Basin, and much of Asia, the house sparrow has been introduced to various regions worldwide, including parts of Australasia, Africa, and the Americas, making it one of the most widely distributed wild birds.

House sparrows are social birds, often seen in flocks. They exhibit a range of behaviors, including dust or water bathing and communal roosting. Males are known to be territorial around their nesting sites.

11-4-2018 VICTORIA FALLS, ZIMBABWE - HOODED VULTURE (Necrosyrtes monachus) COURTESY OF MRS VALERIE FISHER


The hooded vulture (Necrosyrtes monachus) is a small, scruffy-looking vulture with a distinctive cream-colored hood of downy feathers running from the back of its neck to the crown of its head. It has dark brown plumage, a long thin bill, and a bare crown, face, and fore-neck. The face is typically a light red color, flushing red when agitated. This species is one of the smaller members of the Old World vultures.

Adult hooded vultures are characterized by their pinkish-white head, which can turn red when they are excited, and a grey to black "hood." They have broad wings for soaring and a short tail. Both sexes appear similar, though females may have longer eyelashes. Juveniles resemble adults but are darker with a purplish sheen to their body feathers.

Hooded vultures are found in a variety of habitats, including open grasslands, deserts, wooded savannas, forest edges, and coastal areas. They are often seen around human habitation, waste tips, and abattoirs.

This species has a widespread distribution across sub-Saharan Africa, with populations in southern, East, and West Africa. They are most commonly found in the western region of The Gambia.

Hooded vultures are mostly sedentary, rarely moving more than 200 km from their nesting sites. They are known to follow scavenging African wild dogs and hyenas and are often seen in flocks, especially when foraging at abattoirs or on large carcasses. In southern Africa, they tend to be solitary and secretive.


The hooded vulture is usually silent but may emit a shrill, sibilant whistle during copulation and thin squealing calls at nests and carcasses.

These vultures breed in stick nests in trees, often palms, laying a single egg. They may form loose colonies and are most active during the day. The breeding season coincides with the dry season, and young are dependent on their parents for several months post-fledging.

Hooded vultures are scavengers, feeding primarily on carcasses of dead animals and waste. They also consume insects and are seen in large numbers during termite emergences.

The International Union for Conservation of Nature (IUCN) has rated the hooded vulture as "critically endangered." The species faces threats from poisoning, hunting, habitat loss, and collisions with electricity infrastructure.

Protected under various international agreements, conservation actions for the hooded vulture include systematic monitoring, protection schemes, and efforts to regulate and limit the use of pesticides and poisons in regions where the species occurs.
