29-3-2015 KERALA, INDIA - VELVET FRONTED NUTHATCH (Sitta frontalis)

The velvet-fronted nuthatch has the typical nuthatch shape, short tail and powerful bill and feet. It is 12.5 cm long. It is violet-blue above, with lavender cheeks, beige underparts, yellow eyes, and a whitish throat. The iris is distinctly pale and yellow. The bill is red, and there is a black patch on the forehead and lores which is well developed in adults and less so in younger birds. Young birds have a dark beak and dark tips to the undertail coverts. Adult males can be told apart by the black superciliary stripe that runs above the eye and over the head, towards the nape.

Females lack the supercilium and have a warmer underpart colour. Juveniles are duller versions of the adult lacking the black frontal band. There populations differ in shade and size and the distribution of white on the throat.

The velvet-fronted nuthatch is a resident breeder of all types of forests from deciduous to evergreen forest. In the Sunderbans, they are found in Sonneratia mangrove forests. They also live within secondary forest and make use of the shade trees in south Indian coffee plantations.

Like other nuthatches they have strongly curved claws that allow them to climb down vertical tree trunks, unlike species such as woodpeckers that only work their way upwards. It moves jerkily up and down or around tree branches and trunks. It is an active feeder on insects and spiders, gleaned on the bark of the trunk and branches, and may be found in mixed feeding flocks with other passerines. The insects they disturb are sometimes taken by the racket-tailed drongo in Sri Lanka.

28-12-2015 MEKONG DELTA, VIETNAM - BRONZE WINGED JACANA (Metopidius indicus)

The bronze-winged jacana (Metopidius indicus ) is a wader in the family Jacanidae. It is found across South and Southeast Asia and is the sole species in the genus Metopidius. Like other jacanas it forages on lilies and other floating aquatic vegetation, the long feet spreading out its weight and preventing sinking. The sexes are alike but females are slightly larger and are polyandrous, maintaining a harem of males during the breeding season in the monsoon rains. Males maintain territories, with one male in the harem chosen to incubate the eggs and take care of the young. When threatened, young chicks may be carried to safety by the male under his wings.

Bronze-winged jacanas are rail-like, large, short tailed birds that appear dark at a distance except for the supercilium. They are 29 cm (11 in) in length. The sexes are similar but the females are slightly larger than the males. The wings are bronzy brown with a green sheen and have a reduced tubercular carpal spur. The head, neck and breast are black and contrast with the broad white supercilium that runs from over the eye to the back of the neck. The lower back and tail coverts are chestnut. The tail is stubby and reddish brown with black terminal band. The greenish yellow bill has a red-base to the upper mandible. A lappet or frontal shield extends up over the forehead and is reddish purple. The legs are greenish. The toes are long and the straight and the elongated nail on the hind toe is longer than the toe. Downy chicks are light brown with a dark stripe running down the nape. Young birds have brown upperparts, a rufous crown, white underparts, a buff foreneck, an undeveloped frontal shield, and may have a dull supercilium. Adults can be confused at a distance with the common moorhen (which is found in similar habitat) and with the watercock and while young can appear similar to the young of the pheasant-tailed jacana, they lack the black necklace seen in that species.

12-9-2018 ALBUFERA, VALENCIA - MALLARD (FEMALE) (Anas platyrhynchos)

The mallard (/ˈmælɑːrd, ˈmælərd/) or wild duck (Anas platyrhynchos) is a dabbling duck that breeds throughout the temperate and subtropical Americas, Eurasia, and North Africa. It has been introduced to New Zealand, Australia, Peru, Brazil, Uruguay, Argentina, Chile, Colombia, the Falkland Islands, and South Africa. This duck belongs to the subfamily Anatinae of the waterfowl family Anatidae. Males have green heads, while the females (hens or ducks) have mainly brown-speckled plumage. Both sexes have an area of white-bordered black or iridescent purple or blue feathers called a speculum on their wings; males especially tend to have blue speculum feathers. The mallard is 50–65 cm (20–26 in) long, of which the body makes up around two-thirds the length. The wingspan is 81–98 cm (32–39 in) and the bill is 4.4 to 6.1 cm (1.7 to 2.4 in) long.

It is often slightly heavier than most other dabbling ducks, weighing 0.7–1.6 kg (1.5–3.5 lb). Mallards live in wetlands, eat water plants and small animals, and are social animals preferring to congregate in groups or flocks of varying sizes.

The female lays 8 to 13 creamy white to greenish-buff spotless eggs, on alternate days. Incubation takes 27 to 28 days and fledging takes 50 to 60 days. The ducklings are precocial and fully capable of swimming as soon as they hatch.

The mallard is considered to be a species of least concern by the International Union for Conservation of Nature (IUCN). Unlike many waterfowl, mallards are considered an invasive species in some regions. It is a very adaptable species, being able to live and even thrive in urban areas which may have supported more localised, sensitive species of waterfowl before development. The non-migratory mallard interbreeds with indigenous wild ducks of closely related species through genetic pollution by producing fertile offspring. Complete hybridisation of various species of wild duck gene pools could result in the extinction of many indigenous waterfowl. This species is the main ancestor of most breeds of domestic duck, and its naturally evolved wild gene pool has been genetically polluted by the domestic and feral mallard populations.

12-9-2018 ALBUFERA, VALENCIA - LESSER BLACK BACKED GULL (Larus fuscus)

24-11-2016 INLE LAKE, MYANMAR - BLUE THROATED BARBET (Psilopogon asiaticus)

The blue-throated barbet (Psilopogon asiaticus ) is an Asian barbet native to the foothills of the Himalayas and Southeast Asia. It inhabits lowland and montane forests at elevations of 200–2,000 m (660–6,560 ft).It has bright green, blue and red plumage. The barbets get their name from the bristles which fringe their heavy bills; this species eats fruits and insects.

A common inhabitant of lowland and foothill tropical forests, where it sings brightly but often unseen from the canopy; listen for its repeated 3- or 4-syllabled ‘took-o-rrook!’ Tends to be more common in edge areas and degraded forests than other barbets. Bright green with a blue throat, a red-and-yellow crown, and a heavy, pale-based bill. Birds at the northern and western parts of this species’ range have a black brow, while southern birds don’t.

12-9-2018 ALBUFERA, VALENCIA - RED SWAMP CRAYFISH (Procambarus clarkii)

Procambarus clarkii, known variously as the red swamp crayfish, Louisiana crawfish or mudbug, is a species of cambarid crayfish native to freshwater bodies of northern Mexico, and southern and southeastern United States, but also introduced elsewhere (both in North America and other continents), where it is often an invasive pest.

P. clarkii is typically dark red, with long claws and head, small or no spines on the sides of its carapace just below the head, and rows of bright red bumps on the front and side of the first leg.

The native range of P. clarkii is from northern Mexico and far southeastern New Mexico, through the Gulf States to the Florida Panhandle, as well as inland north through the Mississippi Basin to southern Illinois. It has also been introduced, sometimes deliberately, outside its natural range to countries in Asia, Africa, Europe and elsewhere in the Americas. In northern Europe, the populations are self-maintaining but not expanding, while in southern Europe, P. clarkii is multiplying and actively colonizing new territories at the expense of the native crayfish, Astacus astacus and Austropotamobius spp. Individuals are reported to be able to cross many miles of relatively dry ground, especially in wet seasons, although the aquarium trade and anglers may have hastened the spread in some areas (anglers using P. clarkii as fishing bait are thought to have introduced it to the state of Washington). Attempts have also been made to use P. clarkii as a biological control organism, to reduce levels of the snails involved in the lifecycle of schistosomiasis, leading to the dispersal of P. clarkii in, for instance, Kenya.

In Europe, P. clarkii is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.

P. clarkii is most commonly found in warm freshwater bodies such as slow-flowing rivers, marshes, reservoirs, irrigation systems and rice paddies. It is considered to be the most ecologically plastic species in the order Decapoda and is able to grow quickly even in only seasonally present water, being able to tolerate dry spells of up to four months. P. clarkii grows quickly, and is capable of reaching weights over 50 g (1.8 oz) and sizes of 5.5–12 cm (2.2–4.7 in) long. It is also able to tolerate slightly saline water, which is unusual for a crayfish. Additionally, P. clarkii are physiologically capable of tolerating relatively low dissolved oxygen concentrations. The average lifetime of P. clarkii is five years, although some individuals are known to have reached ages (in nature) of over six years.

The burrowing activities of P. clarkii can lead to damage to existing water courses and to crops, particularly rice, and its feeding can disrupt native ecosystems. It may outcompete the native crayfish species and is a vector for the crayfish plague fungus Aphanomyces astaci, for crayfish virus vibriosis and for a number of parasitic worms on vertebrates. Their burrowing activities may also be a threat to civil infrastructure such as storm ponds and levees.

In 2007, troglomorphic specimens of P. clarkii were found in central Portugal in the karst springs of the Rio Anços in the Sicó massif and of the Alviela River in the Estremenho massiff. In 2011, another cave-dwelling population was discovered in caves in the San Giuliano Terme municipality in the Province of Pisa in Italy. Both localities consist of karst landscapes with extensive cave formations. The Portuguese population is entirely depigmented, although pigmented specimens are present in nearby surface streams; the deepest recorded specimen was a male recovered at a depth of 240 metres (790 ft). 53% of Italian specimens displayed a blue-white coloration. The greater presence of pigmented individuals suggests either a more recent entrance, an external source of carotenoids, or movement between surface and underground waters. Collectively, these potations make up the first recorded instances of troglodytic crayfish in Europe. The invasive crayfish have the potential to pose an environmental threat to native stygobitic fauna, due to the crayfish's recorded ability to prey on diverse sources of food and the highly restricted ranges of native cave fauna.

Harvests of P. clarkii for food account for a large majority of the crayfish produced in the United States and elsewhere. Crayfish farming began in Louisiana in the 18th century, taking place in rice fields in a concurrent or alternate culture system. The concurrent polyculture of rice and crayfish combination makes good use of land, resources, equipment and infrastructure already being used for rice production.

However, crayfish production has decreased in recent years due to an increase of imports from China, which is now the world's leading producer of farmed crayfish using a rice-based system. A number of species of crustaceans were introduced to China to create markets for aquaculture and because they are better adapted to growing in a rice field than native fish species. Rice-fish farming originated in China and is once again growing as the yields from Green Revolution practices used to grow rice are no longer increasing, and resources such as land and water are becoming more limited. Crayfish are also cultivated as animal feed for poultry farms, fish farms and Chinese edible frog farms, or used to add into organic fertilizers.

P. clarkii has also been introduced elsewhere for cultivation, such as Spain, where its success is attributable to its ability to colonize disturbed habitats that would be unsuitable for the native crayfish (Astacus astacus). P. clarkii is also marketed by biological supply companies for teaching and research. P. clarkii also exhibits different colour morphs, including white, blue and orange, which are commonly sold in pet stores.

The introduction of P. clarkii has also resulted in economic losses in some regions. In the Baixo Mondego region of Portugal, it caused a decrease in 6.3% of profits in rice fields. However, this was on a wet-seeded field. All negative effects of crayfish can be avoided if adult crayfish are separated from the seed and seedlings.

8-4-2018 THORNYBUSH LODGE, SOUTH AFRICA - VERVET MONKEY (Chlorocebus pygerythrus)

5-4-2018 PHINDA FOREST LODGE, SOUTH AFRICA - NYALA (FEMALE) (Tragelaphus angusii)

The nyala (Tragelaphus angasii) is a spiral-horned antelope native to southern Africa. It was first described in 1849 by George French Angas. They are very shy cautious creatures. They inhabit thickets within dense and dry savanna woodlands and forage during the daylight hours. The main predators of the nyala are lion, leopard, and Cape hunting dog, while baboons and raptorial birds prey on juveniles.

The coat of the nyala is rusty or rufous brown in females and juveniles. It grows a dark brown or slate grey in adult males, often with a bluish tinge. Females and young males have ten or more white vertical stripes on their sides. Other markings are visible on the face, throat, flanks, and thighs. Stripes are very reduced or absent in older males. Both males and females have a white chevron between their eyes and a bushy tail white underside. Both sexes have a dorsal crest of hair running right from the back of the head to the end of the tail. Males have another line of hair along the midline of their chest and belly. Only the males have horns. Horns are 60-83 cm (24-33 in) long and yellow-tipped. There are one or two twists. The spoor is similar to that of the bushbuck, but larger. It is 5-6 cm (2-2.4 in) long. The nyala has hairy glands on its feet, which leave their scent wherever it walks.

Nyala are found across southeast Africa from the Lower Shire Valley in Malawi through Mozambique and Zimbabwe to eastern South Africa and Swaziland. They inhabit dense lowland woodlands, thickets, and lush green river country. They choose places with good quality grasslands as well as the provision of fresh water.

22-4-2018 OKAVANGO DELTA, BOTSWANA - VERREAUX'S EAGLE OWL (Bubo lacteus)

The Verreaux's eagle-owl (Ketupa lactea), also known as the milky eagle owl or giant eagle owl, is a formidable presence in the avian world. As the largest owl found in Africa and the most massive in the tropics, it commands attention with its impressive stature. This species can reach up to 66 cm (26 in) in total length, with females typically out-sizing males. Its plumage is primarily a soft grey, with fine brownish vermiculations on the underside and more solid light brown with white spots on the shoulder. The facial disc is paler, often whitish, with stark black borders. However, its most distinctive feature is the bright pink eyelids, unique among owl species.

When observing Verreaux's eagle-owl, look for its large size, grey plumage, and the striking pink eyelids that are visible when the bird is at rest. The ear tufts are relatively small and may not be noticeable at a distance. The eyes are a deep brown, contrasting with the paler facial disc. In flight, its large wingspan is evident, which can reach nearly 164 cm (5 ft 5 in) in females.

Verreaux's eagle-owl favors dry, wooded savanna environments, often bordering semi-arid regions. It can also be found in riverine forests adjacent to savannas and in small, semi-open woodlands. This species is adaptable to various elevations, from sea level to mountainous areas up to 3,000 m (9,800 ft), though it is generally scarce in rocky terrains.

This eagle-owl is widespread across sub-Saharan Africa, with the highest densities in eastern and southern Africa. It is less common in the dense rainforests of west and central Africa, with a sporadic presence in transitional zones between the Sahara and rainforests.

Nocturnal by nature, Verreaux's eagle-owls spend their days roosting in trees, often on large horizontal branches. They are known to roost lightly, awakening quickly to defend themselves if necessary. Family groups, including offspring from previous years, may roost and preen together. Each pair defends a large territory, which can be up to 7,000 ha (17,000 acres) in size.

The call of the Verreaux's eagle-owl is the deepest among owls, with the male's song resembling a series of deep "gwok" sounds. The female's call is similar but higher-pitched. Their vocalizations can carry for considerable distances, facilitating communication between mates and territorial defense.

Verreaux's eagle-owls are monogamous and likely mate for life. They typically use large stick nests built by other birds, often on top of hamerkop nests or those constructed by large raptors. The female usually lays two white eggs, with the older chick often outcompeting the younger for food. Fledglings leave the nest before they can fly competently and remain dependent on their parents for several months.

Verreaux's eagle-owl is an opportunistic predator with a diet that includes mammals, birds, reptiles, amphibians, and insects. It is known to be the only routine predator of hedgehogs in Africa, skillfully removing their prickly skins before consumption.

The IUCN lists Verreaux's eagle-owl as Least Concern due to its wide range and adaptability to habitat alterations. However, it occurs at low densities, and regional declines have been reported due to habitat destruction, persecution, and the effects of pesticides.

4-4-2018 PHINDA GAME RESERVE, SOUTH AFRICA - COMMON IMPALA (FEMALE) (Aepyceros melampus ssp. melampus)

The impala or rooibok (Aepyceros melampus, lit. 'black-footed high-horn' in Ancient Greek) is a medium-sized antelope found in eastern and southern Africa. The only extant member of the genus Aepyceros, and tribe Aepycerotini, it was first described to Europeans by German zoologist Hinrich Lichtenstein in 1812. Two subspecies are recognised—the grassland-dwelling common impala (sometimes referred to as the Kenyan impala), and the larger and darker black-faced impala, which lives in slightly more arid, scrubland environments. The impala reaches 70–92 cm (28–36 in) at the shoulder and weighs 40–76 kg (88–168 lb). It features a glossy, reddish brown coat. The male's slender, lyre-shaped horns are 45–92 cm (18–36 in) long.

15-4-2018 CHOBE NATIONAL PARK, SOUTH AFRICA - GARDEN INSPECTOR (Precis archesia)

Precis archesia, the garden inspector or garden commodore, is a species of butterfly in the Nymphalidae family, native to Subsaharan Africa.

The Garden Commodore, or Garden Inspector, is a familiar butterfly occurring year round in South Africa, having quite distinctly marked dry season (April to August) and wet season (September to March) variations that could easily be taken to be altogether different species. Females are bigger than the males and at 6cm their wingspan is at least 1cm wider than that of the males. With their wings closed Garden Commodores, especially the dry season form, resemble dead leaves.

As their name suggests, the Garden Inspector is commonly seen in well planted gardens, but their natural habitat is rocky, grass- and savanna-covered hills. They are fast flyers and often land in the open, on bare ground, rocks or pathways. In South Africa they are found from the Eastern Cape, through Kwazulu-Natal into the Lowveld and Bushveld regions of the country.

20-4-2018 OKAVANGO DELTA, BOTSWANA - AFRICAN LION (FEMALE) (Panthera leo)

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.

20-4-2018 OKAVANGO DELTA, BOTSWANA - SOUTHERN AFRICAN GIRAFFE (Giraffa giraffa ssp. giraffa)

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

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

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

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

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

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

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

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

22-4-2018 OKAVANGO DELTA, BOTSWANA - BATELEUR EAGLE (Terathopius ecaudatus)

The Bateleur (Terathopius ecaudatus) is a medium-sized eagle known for its striking appearance and unique flight characteristics. It is the sole member of the genus Terathopius and is closely related to snake eagles. Adults are predominantly black with chestnut on the mantle, rump, and tail, and have distinctive red facial skin and feet. Juveniles are drab brown with paler scaling. The species is characterized by a very large head, small bill, large feet, short legs, long wings, and an exceptionally short tail, which is even shorter in adults.

Bateleurs are generally silent but may emit a loud, raucous "schaaaa-aw" when excited or during courtship. They also produce resonant barking calls and softer calls near the nest.

Bateleurs build small but sturdy stick nests in large trees and lay a single egg. They may take up to 7 to 8 years to reach full maturity. The species is known for its elaborate courtship displays.

Juvenile Bateleurs could be confused with brown snake eagles due to their similar size and proportions, but the latter have yellow eyes and longer legs.

Bateleurs have a generalist diet that includes carrion and a wide range of live prey, such as mammals, birds, and reptiles. They forage from flight, often descending in tight spirals to investigate potential food.

The Bateleur is classified as Endangered by the IUCN due to pronounced population declines caused by habitat destruction, pesticide usage, and persecution. The species is mostly confined to protected areas today.
