10-12-2016 MONTE CORONA, ADOR - EUROPEAN ROBIN (Erithacus rubecula)


The European robin (Erithacus rubecula) is a small insectivorous passerine bird. The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius ), a thrush, and the Australasian robins of the family Petroicidae.

The male and female European robins are similar in coloration, with an orange breast and face lined with grey, brown upperparts, and a whitish belly. The bill and eyes are black. Juveniles are spotted brown and white in coloration, with patches of orange gradually appearing.

European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.

10-12-2016 ALBUFERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)



The Great cormorant (Phalacrocorax carbo) is a widespread member of the cormorant family of seabirds. Many fishermen see in the Great cormorant a competitor for fish. Because of this, it was hunted nearly to extinction in the past but luckily due to conservation efforts, its numbers increased.

The Great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Males are typically larger and heavier than females. It has a longish tail and yellow throat patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters, the Great cormorant can be distinguished from the Common shag by its larger size, heavier build, thicker bill, lack of a crest, and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the Double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants.


Great cormorants occur throughout Europe, Asia, Australia, Africa, and northeastern coastal North America. They may be both resident and migratory. Throughout the year in some areas, large groups remain within the breeding range. Greta cormorants frequent open marine environments and inland waters. They inhabit sandy or rocky sheltered coasts and estuaries and are rarely seen any distance from the coast. This species breeds on cliffs and inshore islands, among boulders and man-made structures. Birds that nest inland will breed on trees, bushes, and reedbeds, and even on bare ground.


Great cormorants are active during the day and are social birds, usually leaving roosts to forage early in the morning and returning within an hour. Little time each day is spent foraging, although parents with young tend to forage for longer. Much of the day is spent resting and preening near foraging areas or at roosts. Great cormorants generally are not aggressive towards one another, apart from at nest sites, where they exhibit territorial behavior. There may be dominance hierarchies. Outside of the breeding season, they usually gather in mixed-age, mixed-sex groups.

10-12-2016 ALBUFERA, VALENCIA - GREAT EGRET (Ardea alba)


The Great egret (Ardea alba) is a large, widely distributed wading bird. Like all egrets, it is a member of the heron family, Ardeidae, and its close relatieves are pelicans. The Great egret is sometimes confused with the Great white heron of the Caribbean, which is a white morph of the closely related Great blue heron.

This elegant heron is completely white with its magnificent plumage, reminding lace. The bill of the Great egret is sharp, long and yellow in color. The bird has long, black feet and legs. During the breeding season, the bill becomes a bit darker while the legs get lighter. This bird possesses a very long neck, exceeding the length of its body. The bird has a notable kink of its neck, curving the necks into a "S" shape when flying. Male and female egrets generally look similar, though females are a bit smaller than males. Young egrets usually look like non-breeding adults. During the breeding season, these birds grow long, lacy shaped feathers known as "aigrettes”, stretching them in an impressive display.


These birds are widely distributed throughout the world including North and South Americas, Eurasia, Africa, and Australia. In Africa, they can be found only outside the breeding season. Great egrets prefer living near any water body, occurring along streams, lakes, in saltwater and freshwater marshes, muddy areas, and ponds. Just like other heron species, these birds are most frequently found in wetlands and wooded swamps.

Great egrets are diurnal feeders. They can feed both in flocks of their own kind and these of other heron species. At sunset, egrets of surrounding areas usually come together, roosting in colonies. They feed in shallow water, walking slowly and looking for prey. And when the prey is spotted, they abruptly thrust the bill into the water, catching it. They will also steal a great part of their food from smaller heron species. After breeding, these birds usually disperse. Egrets, living in mild climates, remain in their breeding areas throughout the winter while those, breeding in northern regions where water freezes during the winter, have to migrate. As with many bird species, Great egrets become rather aggressive when it comes to feeding, even if there's an abundance of food. Occasionally, even parents can fight for food with their young.

10-12-2016 ALBUFERA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)


The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

10-12-2016 ALBUFERA, VALENCIA - ODOROUS ANTS (Subfamily Dolichoderinae)


Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (Linepithema humile), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.


This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland.

Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by ants of this subfamily when crushed or disturbed.

10-12-2016 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)


The Grey heron (Ardea cinerea) is a large long-legged wading bird of the heron native to Europe and Asia and also parts of Africa. It lives in wetland areas and feeds on various aquatic creatures which it catches after standing stationary beside or in the water.

The plumage of the Grey heron is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have a head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight, and powerful, and is brighter in color in breeding adults. The iris is yellow and the legs are brown and very long.


Grey herons occur in most parts of Europe, Asia, and Africa. Over much of their range, these birds are resident, but populations from the more northerly parts of Europe migrate southwards; some remain in Central and Southern Europe, and others travel on to Africa south of the Sahara Desert. Grey herons can be found anywhere with suitable watery habitats that can supply their food. Although most common in the lowlands, they also occur in mountain tarns, lakes, reservoirs, large and small rivers, marshes, ponds, ditches, flooded areas, coastal lagoons, estuaries, and seashore. They sometimes forage away from water in the pasture, and can even be found in desert areas, hunting for beetles and lizards. 

10-12-2016 ALBUFERA, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)


The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The Сommon starling is a medium-sized bird. It has glossy black plumage with a metallic sheen, which is speckled with white at some times of the year. The legs are pink and the bill is black in winter and yellow in summer. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the color of the irises, rich brown in males, mouse-brown, or grey in females.


Common starlings are native to Eurasia and are found throughout Europe, northern Africa (from Morocco to Egypt), India (mainly in the north but regularly extending further south and extending into the Maldives) Nepal, the Middle East including Syria, Iran, and Iraq and north-western China. Common starlings in the south and west of Europe are mainly resident, although other populations migrate from regions where the winter is harsh. Most birds from northern Europe, Russia, and Ukraine migrate southwestwards or southeastwards. In the autumn, when immigrants are arriving from eastern Europe, many of Britain's common starlings are setting off for Iberia and North Africa. Common starlings prefer urban or suburban areas, reedbeds, grassy areas such as farmland, grazing pastures, playing fields, golf courses, and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

10-12-2016 ALBUFERA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)


The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic including Europe and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. The species also occurs in smaller numbers in northeastern North America, where it was formerly known as the common black-headed gull.

The black-headed gull was previously placed in the genus Larus but in agreement with the NACC and SACC, and based on Pons et al. (Pons, J.-M.., A. Hassanin, and P.-A. Crochet. 2005. "Phylogenetic relationships within the Laridae" (Charadriiformes: Aves) inferred from mitochondrial markers, "Molecular Phylogenetics and Evolution" 37: 686-699) and earlier references, extensive changes to the taxonomy of gulls was undertaken and many species of gull were removed from the genus Larus, including the black-headed gull 


The black-headed gull displays a variety of compelling behaviours and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are an overwintering species, found in a variety of different habitats.

This gull is 37–44 cm (14+1⁄2–17+1⁄2 in) long with a 94–110 cm (37–43+1⁄2 in) wingspan and weighs 190–400 g (6+3⁄4–14+1⁄8 oz).

In flight, the white leading edge to the wing is a good field mark. The summer adult has a chocolate-brown head (not black, although does look black from a distance), pale grey body, black tips to the primary wing feathers, and red bill and legs. The hood is lost in winter, leaving just two dark spots. Immature birds have a mottled pattern of brown spots over most of the body, and a black band on the tail. There is no difference in plumage between the sexes.

It breeds in colonies in large reed beds or marshes, or on islands in lakes, nesting on the ground. Like most gulls, it is highly gregarious in winter, both when feeding or in evening roosts. It is not a pelagic species and is rarely seen at sea far from coasts.


The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal relish. It is a noisy species, especially in colonies, with a familiar "kree-ar" call. Its scientific name means laughing gull.

This species takes two years to reach maturity. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood. Like most gulls, black-headed gulls are long-lived birds, with a maximum age of at least 32.9 years recorded in the wild, in addition to an anecdote now believed of dubious authenticity regarding a 63-year-old bird.
Black-headed gulls can be found over much of Europe. It is also found in across the Palearctic to Japan and east China. Small numbers also breed in northeastern Canada and can be seen in winter in northeast North America as far south as Virginia, often with the similar-looking Bonaparte's Gull and also in some Caribbean islands. Recorded as a very rare transient gull in the Carolina coast.

10-12-2016 ALBUFERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)


Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.


Great cormorants have large populations and are widespread, although surveys are not complete across their range. Being an important fish competitor, in the past, they were almost extinct in Europe. However, in recent years increases have been observed, thanks to intensive protection. But in some countries, expanding conflicts with fish farms and fisheries lead to new persecution. Another threat is that hatchlings may be eaten by raptors before fledging.
Population number

The IUCN Red List reports that the global population of Great cormorants is about 1,400,000-2,100,000 individuals. The European population is estimated at 401,000-512,000 pairs, which equates to 803,000-1,020,000 mature individuals. Overall, currently, Great cormorants are classified as Least Concern (LC) on the IUCN Red List and their numbers today are increasing.

10-12-2016 ALBUFERA, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)



The Cattle egret (Bubulcus ibis) is a cosmopolitan species of heron named for its association with cattle. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western cattle egret and the Eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea.


The Cattle egret is a stocky bird. It has a relatively short, thick neck, a sturdy bill, and a hunched posture. The nonbreeding adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During the breeding season, adults of the nominate western subspecies develop orange-buff plumes on the back, breast, and crown, and the bill, legs, and irises become bright red for a brief period prior to pairing. The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill.


Cattle egrets are native to parts of Asia, Africa, and Europe but they have undergone a rapid expansion in their distribution and successfully colonized much of the rest of the world in the last century. Many populations of Cattle egrets are highly migratory, while others are dispersive, and distinguishing between the two can be difficult. In many areas, populations can be both sedentary and migratory. In the Northern Hemisphere, migration is from cooler climes to warmer areas, but Cattle egrets nesting in Australia migrate to cooler Tasmania and New Zealand in the winter and return in the spring. Migration in western Africa is in response to rainfall, and in South America, migrating birds travel south of their breeding range in the non-breeding season. Populations in southern India appear to show local migrations in response to the monsoons. Cattle egrets inhabit wetlands, dry grassy habitats, semi-arid steppes, floodplains, freshwater swamps, shallow marshes, and mangroves. They are often found in fields, croplands, and pastures with poor drainage. When nesting, Cattle egrets are found in woodlands near lakes or rivers, in swamps, or on small inland or coastal islands.

10-12-2016 ALBUFERA, VALENCIA - GLOSSY IBIS (Plegadis falcinellus)


Sometimes called the more cosmopolitan ibis, the Glossy Ibis, is the most widespread ibis species. It can be found in South, North and Central America, southern Europe, Africa, Asia, and Australia. In the US it primarily lives along the Atlantic coast but can also be found in a variety of inland wetlands.

bises have curved, slender bills that they use to probe into shallow water, mud or grass when foraging. Ibises are gregarious birds that live, travel and breed in flocks. In flight, they form diagonal lines or V-formations. This formation decreases wind resistance for trailing birds.


The glossy ibis is a heron-like bird with a long, curving beak. They breed in parts of southern and southeast Europe and are occasional visitors to the UK. However, in recent decades sightings here have become more common, mirroring an increase in their breeding population in southwest Europe.

Flocks of Glossy Ibises wade in the shallows of eastern marshes, probing for food with their sickle-shaped bills. Widespread in the Old World, the species is found in the New World mainly in the West Indies and along our Atlantic Coast, especially Florida, where it was quite scarce as recently as the 1930s. It may have invaded within the last few centuries, riding the trade winds across from West Africa to the Caribbean.


Withdraws from northern part of breeding range in winter. Migrates in flocks, moving south relatively early. Singles and small flocks sometimes wander far north and inland, especially in spring and summer.

Marshes, rice fields, swamps. Forages in shallow waters, favoring marshes (either fresh or salt), flooded fields, shallow ponds, estuaries. Nests in low stands of willows and other shrubs surrounded by marsh, on ground in spartina marsh, in dense thickets of trees and shrubs on higher ground, sometimes in mangroves.

28-11-2016 JURONG, SINGAPORE - SPOT BILLED PELICAN (Pelecanus philippensis)


The spot-billed pelican (Pelecanus philippensis ) or grey pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.

This species was once used by fishermen in parts of eastern Bengal as decoys for certain fish. These fishermen believed that an oily secretion from the bird attracted certain fish such as Colisa and Anabas.

The propensity of these birds to nest close to human habitations has been noted from the time of T C Jerdon:

Several colonies have since been discovered and while many of these have vanished others have been protected and a few villages with nesting colonies have become popular tourist attractions. Well known villages with colonies include Kokrebellur, Koothankulam and Uppalapadu.

28-11-2016 JURONG, SINGAPORE - SCLATER'S CROWNED PIGEON (Goura sclaterii)


Sclater's crowned pigeon (Goura sclaterii ) is a large, terrestrial pigeon confined to the southern lowland forests of New Guinea. This pigeon was previously considered as conspecific with Scheepmaker's crowned pigeon (Goura scheepmakeri ) with the English name "southern crowned pigeon".

It has a bluish-grey plumage with elaborate blue lacy crests, red iris and very deep maroon breast. Both sexes have a similar appearance. It is 66–73 cm (26–29 in) in length and weighs 2.00–2.24 kg (4.41–4.94 lb).


Being tame and heavily hunted for its meat and plumes, Sclater's crowned pigeon is evaluated as near threatened on the IUCN Red List of Threatened Species. It is listed in Appendix II of CITES.

28-11-2016 JURONG, SINGAPORE - ECLECTUS PARROT (MALE) (Eclectus roratus)


The Papuan eclectus, red-sided eclectus, or New Guinea eclectus (Eclectus polychloros) is a parrot species which is native to New Guinea. Larger than the Moluccan eclectus, the green plumage of the male only has a slight yellow tinge and the tail is tipped with a half-inch yellow band. The central tail feathers are green and lateral ones blue and green. It is widely distributed from Kai Islands and western islands of the West Papua province in the west, across the island of New Guinea to the Trobriands, D'Entrecasteaux Islands, Louisiade Archipelago, Bismarck Archipelago, and Solomon Islands to the east, and south to the northern Cape York Peninsula of Australia. It has also been introduced to the Goram Islands, Indonesia.


The Papuan eclectus nests in tree cavities and breeds from April to September. Two eggs are typically laid.


The Papuan eclectus nests in tree cavities and breeds from April to September. Two eggs are typically laid.

The Papuan eclectus is a popular pet parrot and there is a large avicultural population. Many Papuan eclectus in captivity in Australia are apparently hybrids between subspecies E. p. polychloros and E. p. solomonensis, as Taronga Zoo Sydney had a flock of these two subspecies in a large aviary many years ago. Specimens of the Australian subspecies E. p. macgillivrayi have only recently entered the aviculture market in Australia and are more expensive.


The World Parrot Trust recommends that the Papuan eclectus be kept in an enclosure with a minimum length of 3 metres (9.8 ft). It may live for up to 50 years in captivity.

28-11-2016 JURONG, SINGAPORE - CRESTED PIGEON (Ocyphaps lophotes)


The Crested pigeon (Ocyphaps lophotes) is an Australian species of pigeon. Only two Australian pigeon species possess an erect crest, the Crested pigeon and the spinifex pigeon. The Crested pigeon is sometimes referred to as a Topknot pigeon, a common name shared with the reddish crested Lopholaimus antarcticus of Eastern Australia. Common names for the species, aside from crested or Topknot pigeon, characterize them as a 'bronzewing' or 'dove' that is likewise distinguished by the crest.

Crested pigeons are found throughout mainland Australia except for the far northern tropical areas. They live in lightly wooded grasslands in both rural and urban areas, and can also visit watercourses, homestead gardens, grain farming areas, pastoral areas, sports grounds, and golf courses.

Crested pigeons are highly social birds and often gather in flocks of varying sizes. They are active during the day but prefer to forage in the morning and in the evening. They forage in small to large groups, which also gather to drink at waterholes. The most distinctive behavior of Crested pigeons is the beating and whistling sound their wings make when they take off. This is most likely to draw the attention of predators to birds on the wing, and away from any birds remaining on the ground, and as an alarm call to other pigeons. When the birds land, their tails tilt upwards and the flight patterns are similar to those of the Spotted turtle dove. If startled, Crested pigeons take to the air producing a distinctive whistling 'call'.

28-11-2016 JURONG, SINGAPORE - PERUVIAN PELICAN (Pelecanus thagus)


The Peruvian pelican (Pelecanus thagus ) is a member of the pelican family. It lives on the west coast of South America, breeding in loose colonies from about 33.5° in central Chile to Piura in northern Peru, and occurring as a visitor in southern Chile and Ecuador.


These birds are dark in colour with a white stripe from the top of the bill up to the crown and down the sides of the neck. They have long tufted feathers on the top of their heads. It was previously considered a subspecies of the brown pelican (Pelecanus occidentalis ). The Peruvian pelican is considerably larger, ranging from about 5 to 7 kg (11–15 lb) in weight, 137 to 152 cm (4.5–5.0 ft) in length and with a wingspan of about 228 cm (7.5 ft). Compared to the brown pelican, it also has proportionally longer crest feathers, as well as differences in the colours of the gular pouch, beak, scapulars and greater wing coverts.


The main breeding season occurs from September to March. Clutch size is usually two or three eggs. Eggs are incubated for approximately 4 to 5 weeks, with the rearing period lasting about 3 months.


Its status was first evaluated for the IUCN Red List in 2008, being listed as Near threatened.


This bird feeds on several species of fish. Unlike the brown pelican, it never dives from a great height to catch it food, instead diving from a shallow height or feeding while swimming on the surface. On occasion it may take other food items, such as nestling of imperial shags, young Peruvian diving petrels, gray gulls and cannibalize unrelated chicks of its own species.

28-11-2016 JURONG, SINGAPORE - WHITE CROWNED ROBIN CHAT (Cossypha albicapillus)


The white-crowned robin-chat (Cossypha albicapilla ) is a species of bird in the family Muscicapidae.It is found in Benin, Burkina Faso, Cameroon, Central African Republic, Ivory Coast, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Mali, Niger, Nigeria, Senegal, Sierra Leone, South Sudan, and Togo.Its natural habitats are dry savanna and subtropical or tropical moist shrubland.

The white-crowned robin-chat (Cossypha albicapillus) is a species of bird in the family Muscicapidae. It is found in Benin, Burkina Faso, Cameroon, Central African Republic, Ivory Coast, Ethiopia, Gambia, Ghana, Guinea, Guinea-Bissau, Mali, Niger, Nigeria, Senegal, Sierra Leone, South Sudan, and Togo. Its natural habitats are dry savanna and subtropical or tropical moist shrubland.


It has typically been assumed to be monogamous. However, at least one instance of cooperative breeding and possible multiple paternity has been observed.

A large and colorful robin-chat with a black face mask that continues onto the chin. The color of the crown is pure white in the far western part of the range, and white with black markings elsewhere. A shy bird of dense thickets, gardens, and forest, often along rivers and streams. Similar to Snowy-crowned Robin-Chat, but larger, usually with black markings in the white crown, and with a black rather than orange chin. Usually detected by song, a fast and complex mix of musical whistles.


White-crowned Robin-chat primarily feeds on a diet of insects, with a particular preference for termites and ants. It forages on the ground, flipping over leaves and debris to locate its prey. Its unique adaptation lies in its skilled hunting technique.


White-crowned Robin-chat typically inhabits a variety of wooded environments, ranging from thickets and gallery forests in regions receiving annual rainfall between 300–500 mm, to dry savanna-woodlands. Its preferred habitats also include dense riverine scrubs, overgrown plantations, and gardens with rich, shady undergrowth. White-crowned Robin-chat is adaptable and can be found from sea level up to an altitude of around 950 meters, with the race omoensis occupying woodland thickets in rocky hills, at approximately 1500 meters.

28-11-2016 JURONG, SINGAPORE - VIOLET BACKED STARLING (FEMALE) (Cinnyricinclus leucogaster)


The violet-backed starling (Cinnyricinclus leucogaster), also known as the plum-coloured starling or amethyst starling, is a relatively small species (17 cm) of starling in the family Sturnidae. It is the only member of the genus Cinnyricinclus. This strongly sexually dimorphic species is found widely in the woodlands and savannah forest edges of mainland sub-Saharan Africa. It is rarely seen on the ground, but instead found in trees and other locations away from the ground.

The violet-backed starling is a sexually dimorphic species with adults reaching a length of about 18 cm (7 in). The male has an iridescent violet head and back and pure white underparts. The female has a thrush-like appearance with brown, boldly-streaked upper parts and white, heavily-streaked underparts. Both sexes have yellow irises and black bills and legs.
 
The violet-backed starling is a common bird in Sub-Saharan Africa, occurring in most locations with the exception of the dense rainforest of the Congo Basin, and the more arid parts of southwestern Africa. It is found in open woodland, gallery forests, forest verges and clearings. In the Chyulu Hills of Kenya, it occurs at altitudes up to 2,100 m (6,900 ft).

28-11-2016 JURONG, SINGAPORE - VILLAGE WEAVER (Ploceus cucullatus)


The village weaver (Ploceus cucullatus ), also known as the spotted-backed weaver or black-headed weaver (the latter leading to easy confusion with P. melanocephalus ), is a species of bird in the family Ploceidae found in much of sub-Saharan Africa. It has also been introduced to Portugal as well as to the islands of Hispaniola, Martinique, Puerto Rico, Mauritius and Réunion.

This often abundant species occurs in a wide range of open or semi-open habitats, including woodlands and human habitation, and frequently forms large noisy colonies in towns, villages and hotel grounds. This weaver builds a large coarsely woven nest made of grass and leaf strips with a downward facing entrance which is suspended from a branch in a tree. Two to three eggs are laid. Village weavers are colonial breeders, so many nests may hang from one tree.

Village weavers feed principally on seeds and grain, and can be a crop pest, but it will readily take insects, especially when feeding young, which partially redresses the damage to agriculture. The calls of this bird include harsh buzzes and chattering.


The village weaver is a stocky 15–17 cm bird with a strong conical bill and dark reddish eyes. In the northern part of its range, the breeding male has a black head edged by chestnut (typically most distinct on the nape and chest). Towards the southern part of its range, the amount of black and chestnut diminish, and the breeding males of the southernmost subspecies only have a black face and throat, while the nape and crown are yellow. In all subspecies the breeding male has a black bill, black and yellow upperparts and wings, and yellow underparts.

The non-breeding male has a yellow head with an olive crown, grey upperparts and whitish underparts. The wings remain yellow and black. The adult female has streaked olive upperparts, yellow and black wings, and pale yellow underparts. Young birds are like the female but browner on the back.

The silver pheasant is common in aviculture, and overall also remains common in the wild, however, some of its subspecies are rare and threatened.

Silver pheasants are found on mainland Southeast Asia, and in eastern and southern China. They prefer forest edges with open areas and rarely occur in dense forests.

Silver pheasants are gregarious ground-dwelling birds that are usually seen in small flocks. Silver pheasants are active during the day and prefer to forage in the morning and in the evening. They spend most of their life on the ground and will fly only to escape danger. These birds communicate with the help of loud whistles, high-pitched chirping and during the courtship display, males produce cackles and grunts.
