28-11-2016 JURONG, SINGAPORE - AFRICAN GREY PARROT (Psittacus erithacus)

The grey parrot (Psittacus erithacus ), also known as the Congo grey parrot, Congo African grey parrot or African grey parrot, is an Old World parrot in the family Psittacidae. The Timneh parrot (Psittacus timneh) once was identified as a subspecies of the grey parrot, but has since been elevated to a full species.

The African grey parrot is one of the largest parrots in Africa. It is predominantly grey in color and has darker grey than its body over the head and both wings. The head and body feathers have slight white edges. Its tail feathers are red. The coloration of juveniles is similar to that of adults; however, their eyes are dark grey to black, in comparison to the yellow irises around dark eyes of the adult birds, and their undertail coverts are tinged with grey.

African grey parrots are native to equatorial Africa, including Angola, Cameroon, the Congo, Gabon, Ivory Coast, Ghana, Kenya, and Uganda. They are found inside a range from Kenya to the eastern part of the Ivory Coast. These birds favor dense forests, but can also be found at forest edges, mangrove forest, and in more open vegetation types, such as gallery and savanna forests. They can also visit cultivated areas and even gardens.

They can also visit cultivated areas and even gardens.

African grey parrots are gregarious and very noisy birds especially at night when they gather in large flocks to sleep together in tall trees. During the day, they prefer to spend time in smaller groups and fly long distances to forage. African grey parrots feed mainly in the canopy climbing from one branch to another but may also take clay and mineral soil on the ground. These birds communicate with each other using high-pitched screams and whistles. They also use contact calls, which allow them to interact with their flock mates and communicate information about their location, detection of predators, availability of food, and safety status. In addition, contact calls are used to form strong social bonds with their flock mates.

28-11-2016 JURONG, SINGAPORE - GREATER BLUE EARED STARLING (Lamprotornis chalybaeus)

The greater blue-eared starling or greater blue-eared glossy-starling (Lamprotornis chalybaeus ) is a bird that breeds from Senegal east to Ethiopia and south through eastern Africa to northeastern South Africa and Angola. It is a very common species of open woodland bird, and undertakes some seasonal migration.

The greater blue-eared starling is a 22 cm long, short tailed bird. This starling is glossy blue-green with a purple-blue belly and blue ear patch. Its iris is bright yellow or orange. The sexes are similar, but the juvenile is duller and has blackish brown underparts.

The populations from southern Kenya southwards are smaller than northern birds and are sometimes considered to be a separate subspecies, L. c. sycobius.

The lesser blue-eared starling is similar to this species, but the blue of the belly does not extend forward of the legs.

The greater blue-eared starling has a range of musical or grating calls, but the most familiar is a nasal squee-ar.

Like other starlings, the greater blue-eared starling is an omnivore, taking a wide range of invertebrates seeds and berries, especially figs, but is diet is mainly insects taken from the ground.

It will perch on livestock, feeding on insects disturbed by the animals and occasionally removing ectoparasites.

The greater blue-eared starling nests in holes in trees, either natural or excavated by woodpeckers or barbets. It will also nest inside the large stick nests of the sacred ibis or Abdim's stork. A nest will include three to five eggs, which are usually greenish-blue with brown or purple spots, and hatch in 13–14 days. The chicks leave the nest roughly 23 days after hatching.

This species is parasitised by the great spotted cuckoo and occasionally by the greater honeyguide.

The greater blue-eared starling is highly gregarious and will form large flocks, often with other starlings. Its roosts, in reedbed, thorn bushes, or acacia, may also be shared.

28-11-2016 JURONG, SINGAPORE - RUFOUS CROWNED ROLLER (Coracias naevius)

The name "purple roller" can also refer to the azure dollarbird (Eurystomus azureus) of Indonesia.

The purple roller (Coracias naevius), or rufous-crowned roller, is a medium-sized bird widespread in sub-Saharan Africa. Compared with other rollers its colours are rather dull and its voice harsh and grating.

The purple roller is the largest of the rollers, growing to a length of 35 to 40 cm (14 to 16 in). Adults weigh from 145 to 200 g (5.1 to 7.1 oz) with an average weight of 168 g (5.9 oz). From a distance it appears a dull brownish bird with a white stripe over the eye, a patch of white on the nape and a dark tail. Northern populations tend to have a rufus crown while southern populations have a more olive-green crown. The underparts are purplish-pink streaked with white. The wings are long and rounded while the tail is square-cut. The voice is a rather grating "ka" or "gaa", repeated rapidly and evenly.

Its preferred habitat is dry thornveld where it spends long periods perched at the top of thorn trees or poles, watching for food items such as insects, spiders, scorpions and small lizards on the ground. It rocks to-and-fro about its longitudinal axis during display flights, calling raucously all the while; starting from above the treetops it plummets towards the ground in rolling flight. It is territorial, and during the breeding season will drive off other rollers, small hawks and crows.

This species seems to be an opportunist breeder, possibly linked to rains, as its breeding season varies from place to place. It nests in natural hollows in trees or uses old woodpecker holes, or in cliffs, riverbanks, pipes, or holes in masonry, usually laying three white eggs. The young are fed and incubated by both parents.

28-11-2016 JURONG, SINGAPORE - EMERALD STARLING (Lamprotornis iris)

The emerald starling (Lamprotornis iris ) is also known as the iris glossy starling. It is a small starling with a metallic green crown, upper body, wings and tail. The ear-coverts and underparts are metallic purple. Both sexes are similar. Most taxonomists unite it with many other glossy starlings in Lamprotornis, while others place it in a monotypic genus Coccycolius.

A beautiful and distinctive starling that is mainly iridescent green, with a purple iridescent cheek patch and belly. In poor light, can look black. Also note the dark eye. Found locally in lush savanna and woodland, usually in small groups that often perch up in dead trees. Somewhat similar to some other glossy savanna-dwelling starlings, but smaller than most, and easily separated by the bright green plumage and the dark eye. The vocalizations include nasal and squeaky calls.

One of the smallest species among starlings, the emerald starling is distributed in West Africa. It inhabits lowlands and savanna of Côte d'Ivoire, Guinea and Sierra Leone. The emerald starling feeds on figs, Haronga berries and other fruit, seeds, ants and other small insects. The cup-shaped nest is built in a tree cavity. The male and female cooperate in building the nest from leaves, and both bring food to chicks after they hatch. Females possess a brood patch—a spot on their stomach lacking feathers—that helps them transfer body heat to their eggs.

It was formerly classified as data deficient by the IUCN, as available data was insufficient for judging its conservation status. Studies found that it was relatively widespread and locally common, and in 2015 its IUCN rating was changed to least concern. The emerald starling is caught for the wildlife trade and is locally threatened by mining activities, but overall this is unlikely to cause a major decline in the species.

28-11-2016 JURONG, SINGAPORE - ZEBRA DOVE (Geopelia striata)

The zebra dove (Geopelia striata ), also known as the barred ground dove, or barred dove, is a species of bird of the dove family, Columbidae, native to Southeast Asia. They are small birds with a long tail, predominantly brownish-grey in colour with black-and-white barring. The species is known for its pleasant, soft, staccato cooing calls.

The birds are small and slender with a long, narrow tail. The upperparts are brownish-grey with black-and-white barring. The underparts are pinkish with black bars on the sides of the neck, breast and belly. The face is blue-grey with bare blue skin around the eyes. There are white tips to the tail feathers. Juveniles are duller and paler than the adults. They can also have brown feathers. Zebra doves are 20–23 centimetres in length with a wingspan of 24–26 cm.

Their call is a series of soft, staccato cooing notes. In Thailand and Indonesia, the birds are popular as pets because of their calls and cooing competitions are held to find the bird with the best voice. In Indonesia this bird is called perkutut. In the Philippines they are known as batobatong katigbe ("pebbled katigbe") and kurokutok ; in Malaysia this bird is called merbuk, onomatopoeic to their calls. They are also known as tukmo in Filipino, a name also given to the spotted dove (Spilopelia chinensis ) and other wild doves.

The native range of the species extends from Southern Thailand, Tenasserim, Peninsular Malaysia, and Singapore to the Indonesian islands of Sumatra and Java. It may also be native to Borneo, Bali, Lombok, Sumbawa, and the Philippine islands.

The zebra dove is popular in captivity and many populations have appeared outside its native range due to birds escaping or being deliberately released. It can now be found in central Thailand, Laos, Borneo, Sulawesi, Hawaii (introduced in 1922), Tahiti (1950), New Caledonia, the Seychelles, the Chagos Archipelago (1960), Mauritius (before 1768), Réunion, and Saint Helena.

It inhabits scrub, farmland, and open country in lowland areas and is commonly seen in parks and gardens. Trapping for the cagebird industry has led to them becoming rare in parts of Indonesia but in most parts of its range it is common. Zebra doves are among the most abundant birds in some places such as Hawaii and the Seychelles.

The zebra dove feeds on small grass and weed seeds. They will also eat insects and other small invertebrates. They prefer to forage on bare ground, short grass or on roads, scurrying about with rodent-like movement. Unlike other doves, they forage alone, or in pairs. Their colouration camouflages them wonderfully when on the ground.

In its native range the breeding season is from September to June. The males perform a courtship display where they bow and coo while raising and spreading the tail. Upon selection of a nesting site, the female will place herself there and will make guttural sounds to attract males to help build the nest. The nest is a simple platform of leaves and grass blades. It is built in a bush or tree or sometimes on the ground and sometimes on window ledges. One or two white eggs are laid and are incubated by both parents for 13 to 18 days. The young leave the nest within two weeks and can fly well after three weeks.

28-11-2016 JURONG, SINGAPORE - SPOTTED DOVE (Streptopelia chinensis)

The Spotted dove (Spilopelia chinensis) is a small pigeon that is a common across its native range on the Indian subcontinent and in Southeast Asia. These birds are also called the Mountain dove, Pearl-necked dove, Lace-necked dove, and Spotted turtle-dove.

The ground color of this long and slim dove is rosy buff below shading into grey on the head and belly. There is a half collar on the back and sides of the neck made of black feathers that bifurcate and have white spots at the two tips. The median coverts have brown feathers tipped with rufous spots in the Indian and Sri Lankan subspecies which are divided at the tip by a widening grey shaft streak. The wing feathers are dark brown with grey edges. The center of the abdomen and vent are white. The outer tail feathers are tipped in white and become visible when the bird takes off. The male and the female are similar, but juveniles are duller than adults and do not acquire the neck spots until they are mature.

28-11-2016 JURONG, SINGAPORE - LESSER ORIENTAL CHEVROTAIN (Tragulus kanchil)

The lesser mouse-deer, lesser Malay chevrotain, or kanchil (Tragulus kanchil ) is a species of even-toed ungulate in the family Tragulidae.

The Lesser mouse-deer is the smallest known hoofed mammal that is widely distributed across Southeast Asia. They are generally reddish-brown in color with white underparts. Mouse-deer don't possess horns, but males have enlarged sharp upper canine teeth that protrude from the mouth. Females of this species are usually slightly larger than males.

Lesser mouse-deer are found in Indochina, Burma (Kra Isthmus), Brunei, Cambodia, China (Southern Yunnan), Indonesia (Kalimantan, Sumatra, and many other small islands), Laos, Malaysia (Peninsular Malaysia, Sarawak, and many other small islands), Singapore, Thailand, and Vietnam. They live in tropical moist forests, swamp forests, mangrove forests, and moist savanna and shrubland. They can also be found in cultivated areas.

Lesser mouse-deer are shy and generally solitary animals; however, they may sometimes be seen spending time in pairs. Both the males and females occupy home territories which overlap considerably; however, individuals of the same sex do not share their territories. Lesser mouse-deer are often thought to be nocturnal but in fact, they are typically active in the morning and in the afternoon. During the day, they roam in crown-gap areas with dense undergrowth, and at night, they typically move to higher and drier ridge areas. When sensing danger Lesser mouse-deer "freeze" and remain motionless and when alarmed they may repeatedly and rapidly stamp their hind legs.

The breeding season of Lesser mouse-deer occurs throughout the year. The gestation period lasts around 140-177 days and females may produce 2-3 fawns per year. The newly born fawn is able to stand within 30 minutes after birth, however, it remains hidden in the dense brush until it's weaned. Young Lesser mouse-deer grow very quickly and females become reproductively mature at age of 125 days while males are ready to breed when they are 166 days old.

Lesser mouse-deer are threatened by habitat loss due to urban development and farming, hunting, and predation by feral dogs.

28-11-2016 JURONG, SINGAPORE - RADJAH SHELDUCK (Tadorna radjah)

The radjah shelduck (Radjah radjah ), is a species of shelduck found mostly in New Guinea and Australia, and also on some of the Moluccas. It is known alternatively as the raja shelduck, black-backed shelduck, or in Australia as the Burdekin duck.

Both the male and female of the species are mostly white, with dark wing-tips and a distinctive "collar" of dark feathers. Seen from above in flight the birds have green bands on the tops of their wings. The female has a harsh rattle and the male has a breathy, sore-throat whistle.

The radjah shelduck inhabits the mangrove forests and coastline of New Guinea (West Papua and Papua New Guinea) and Australia, and some of the Moluccas in eastern Indonesia. In Australia, its primary range is coastal tropical northern Australia, from central Queensland through northern Northern Territory (including Kakadu National Park) to the Kimberley in Western Australia. The radjah shelduck is listed as a protected bird in all states of Australia and penalties exist for harming or disturbing them.

The species prefers the brackish waters of mangrove flats and paperbark tree swamps, but will visit freshwater swamps, lagoons, and billabongs further inland during the wet season.

28-11-2016 JURONG, SINGAPORE - PINK NECKED GREEN PIGEON (Treron vernans)

The pink-necked green pigeon (Treron vernans ) is a species of bird of the pigeon and dove family, Columbidae. It is a common species of Southeast Asia, found from Myanmar and Vietnam south through to the major islands of Indonesia and the Philippines (where it is called "punay"). It is a medium-sized pigeon with predominantly green plumage; only the male has the pink neck that gives the species its name. The species lives in a wide range of forested and human-modified habitats and is particularly found in open habitats. Its diet is dominated by fruit, in particular figs. Pairs lay two eggs in a flimsy twig nest in a tree, shrub, or hedge, and work together to incubate the eggs and raise the chicks. The species is thought to be an important disperser of fruit seeds. The species has adapted well to human changes to the environment, and can be found in crowded cities as long as fruiting trees are present. It is not considered to be at risk of extinction.

The pink-necked green pigeon is a medium-sized pigeon, measuring 25 to 30 cm (9.8–11.8 in) in length and weighing around 105–160 g (3.7–5.6 oz). The species has sexually dimorphic plumage. The male has a grey head, pinkish neck and upper breast, and the rest of the breast is orange. The back is olive green and the wings are green with black primaries and yellow edging on the tertiaries which create a yellow bar across the wing in flight. The belly is yellowish with grey flanks, and the tail is grey with a black band at the end, and a chestnut uppertail coverts. The female is smaller overall, has a yellowish belly, throat and face, and greenish crown and back of the neck, although is otherwise similar to the male. The legs are pink or reddish, and the bill is white, pale blue green or grey. Juvenile birds look similar to females but are greyer above.

Pigeons in the genus Treron are unusual in the family for not having cooing calls, instead making whistling and quacking noises, but some cooing notes have been recorded for the pink-necked green pigeon, as the male makes a tri-syballic whistling call ending in a coo. It is also reported to make a rasping krrak krrak... call, but the species is generally held to not be particularly vocal, usually only calling in communal roosts and when it finds food.

The range of the pink-necked green pigeon extends from southern Myanmar, Thailand, Cambodia, and Vietnam south through the Malay Peninsula and across the Greater Sundas (and their surrounding islands), Bali, Lombok, Sumbawa, and as far east as the Moluccas as well as the Philippines. It occupies a variety of habitats, including primary forest, forest edge, secondary forest, and coastal mangroves. It favours more open environments and where it is found in association with denser forest it is typically on the edges. It is also readily found in human dominated environments such as gardens, plantations and farmland. It is more common in lowlands and close to the coast, but can be found up to 300 m (980 ft) in the Philippines, 750 m (2,460 ft) in Borneo and 1,200 m (3,900 ft) in Sulawesi. The species is recorded as non-migratory by the Handbook of the Birds of the World, but other sources have described it as making local movements. A related species, the thick-billed green pigeon, covers vast distances in search of fruit, and it is likely that the pink-necked green pigeon has a similar behaviour.

After the main island of Krakatoa was obliterated in a volcanic eruption in 1883, leaving a handful of smaller islands, the pink-necked pigeon was observed on the first bird survey of these remnants. The survey was conducted in 1908, and at the time the pigeon was the only obligate frugivore (meaning it ate mostly fruit, as opposed to as part of a wider diet or opportunistically) that had established itself on the islands. Within the archipelago it was able to colonise Anak Krakatau, a volcano that emerged from the sea from the caldera in 1927, within 36 years of the new island suffering a large eruption in 1952. The delay between the island settling down and colonisation was likely due to the time taken for figs to become established on the island and begin fruiting. It later became extinct on that island, due to a small population and predation. The species has recently expanded its range, having colonised Flores at some time since 2000.

28-11-2016 JURONG, SINGAPORE - LESSER WHISTLING DUCK (Dendrocygna javanica)

The lesser whistling duck (Dendrocygna javanica ), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.

This chestnut brown duck is confusable only with the fulvous whistling duck (D. bicolor ) but has chestnut upper-tail coverts unlike the creamy white in the latter. The ring around the eye is orange to yellow. When flying straight, their head is held below the level of the body as in other Dendrocygna species. The crown appears dark and the sexes are alike in plumage. They fly slowly but with rapid wing-flapping and usually produce a repetitive wheezy seasick call as they circle overhead. They are very nocturnal and often rest during the day. The outermost primary feather has the inner vane modified. They produce very prominent whistling sound while flying.

They are very nocturnal and often rest during the day. The outermost primary feather has the inner vane modified. They produce very prominent whistling sound while flying. Large numbers are sometimes found in urban wetlands such as in Kolkata and Goa, particularly during winter. In the Alipore Zoological Gardens, captive individuals were introduced in the 1930s and wild birds joined this nucleus subsequently.

With a wide distribution range between 1 and 10 million km², they are considered to have a secure global population of between two and twenty million individuals. They are not threatened by hunting as they are not considered good to eat. Hunters in Assam however have been known to raise the ducklings to serve as live decoy.

Lesser whistling duck are usually gregarious. They feed mainly on plants taken from the water as well as grains from cultivated rice apart from small fish, frogs and invertebrates such as molluscs and worms. They dabble as well as dive in water. They will often waddle on the land and Common mynas have been noted to follow them on grass. Courtship involves the male facing the female and dipping and raising its bill in the water and swimming around the female. They breed during the monsoon or rainy season and may vary locally in relation to the food availability. The nest site may be a tree hole lined with twigs and grass or built in the fork of a large tree, sometimes reusing an old nest of a kite or heron or even on the ground. The clutch varies from 7 to 12 white eggs that are incubated by both the parents. Large clutches of up to 17 have been noted although these may be indications of intraspecific brood parasitism. The eggs hatch after about 22–24 days. More than one brood may be raised in a single season. Young birds may sometimes be carried on the back of the parents.

28-11-2016 JURONG, SINGAPORE - SADDLE BILLED STORK (Ephippiorhynchus senegalensis)

The saddle-billed stork or saddlebill (Ephippiorhynchus senegalensis ) is a large wading bird in the stork family, Ciconiidae. It is a widespread species which is a resident breeder in sub-Saharan Africa from Sudan, Ethiopia and Kenya south to South Africa, and in The Gambia, Senegal, Côte d'Ivoire and Chad in west Africa. It is considered endangered in South Africa.

It is a close relative of the widespread Asian and Australian black-necked stork, the only other member of the genus Ephippiorhynchus.

This is a huge bird that regularly attains a height of 145 to 150 cm (4 ft 9 in to 4 ft 11 in), a length of 142 cm (4 ft 8 in) and a 2.4 to 2.7 m (7 ft 10 in to 8 ft 10 in) wingspan. While heights published have been in the aforementioned narrow range, reportedly adult saddle-billed storks in captivity can attain a height of up to 150 to 180 cm (4 ft 11 in to 5 ft 11 in). The male of the species is larger and heavier than the female, with a range of 5.1–7.52 kg (11.2–16.6 lb), with a mean mass of 6.38 kg (14.1 lb). The female is usually between 5 and 6.84 kg (11.0 and 15.1 lb), with a mean mass of 5.95 kg (13.1 lb). Among the large storks, the saddle-billed broadly overlap in size with the two larger Leptoptilos and the Jabiru stork but possesses a longer, more slender neck and slightly longer legs than the other largest storks, so the saddle-billed is likely to be the tallest extant species of the family. Its extremely long legs measure up to 36.5 cm (14.4 in)) in tarsus length. The long bill measures from 27.3 to 36 cm (10.7 to 14.2 in). The sexes can be readily distinguished by the golden yellow irises of the female and the brown irises and dangling yellow wattles of the male. It is therefore one of the few storks to display sexual dimorphism in colour.

It is spectacularly plumaged; both the female and male appear identical when perched but the female shows much more white in the primaries in flight. The head, neck, back, wings, and tail are iridescent black, with the rest of the body and the primary flight feathers being white. Juveniles are browner grey in plumage. The massive bill is red with a black band and a yellow frontal shield (the "saddle"). The legs and feet are black with pink hocks. On the chest is a bare red patch of skin, whose colour darkens during breeding season.

At the continental scale, saddle-billed storks preferred protected areas that have a higher extent of open water compared to areas without the storks. Some of these trends may, however, be due to a bias in coverage by ornithologists of safer areas such as national parks and protected swamps that afford easier accessibility and comforts.

They are silent except for bill-clattering at the nest. Like most storks, these fly with the neck outstretched, not retracted like a heron; in flight, the large heavy bill is kept drooping somewhat below belly height, giving these birds a very unusual appearance to those who see them for the first time. To experienced birdwatchers on the other hand, this makes them easily recognizable even if seen from a distance. It has been suggested that due to the large size and unusual appearance in flight, this species is the basis for the "big bird" and kongamato cryptids.

28-11-2016 JURONG, SINGAPORE - PAINTED STORK (Mycteria leucocephala)

The painted stork (Mycteria leucocephala ) is a large wader in the stork family. It is found in the wetlands of the plains of tropical Asia south of the Himalayas in the Indian Subcontinent and extending into Southeast Asia. Their distinctive pink tertial feathers of the adults give them their name. They forage in flocks in shallow waters along rivers or lakes. They immerse their half open beaks in water and sweep them from side to side and snap up their prey of small fish that are sensed by touch. As they wade along they also stir the water with their feet to flush hiding fish. They nest colonially in trees, often along with other waterbirds. The only sounds they produce are weak moans or bill clattering at the nest. They are not migratory and only make short distance movements in some parts of their range in response to changes in weather or food availability or for breeding. Like other storks, they are often seen soaring on thermals.

Painted storks are large waders found in the wetlands of the plains of tropical Asia. Their distinctive pink flight feathers of the adults give them their name. These beautifully colored birds have a heavy yellow beak with a down-curved tip that gives them a resemblance to an ibis. Males and females appear alike but the males of a pair are usually larger than the female.

Painted storks are widely distributed over the plains of Asia. They are found south of the Himalayan ranges and are bounded on the west by the Indus River system where they are rare and extend eastwards into Southeast Asia. Painted storks are absent from very dry or desert regions, dense forests, and the higher hill regions. They prefer freshwater wetlands in all seasons, but also use irrigation canals and crop fields, particularly flooded rice fields during the monsoon.

Painted storks are not migratory and only make short-distance movements in some parts of their range in response to changes in weather or food availability or for breeding. These birds are highly gregarious and feed in groups in shallow wetlands, crop fields, and irrigation canals. Painted storks feed mainly on small fish which they sense by touch while slowly sweeping their half-open bill from side to side while it held submerged. They walk slowly and also disturb the water with their feet to flush hiding fish. They forage mainly in the day but may forage late or even at night under exceptional conditions. After they are fed Painted storks may stand still on the shore for long durations. Like other storks, they are mostly silent but clatter their bills at the nest and may make some harsh croaking or low moaning sounds at the nest.

28-11-2016 JURONG, SINGAPORE - RUDDY SHELDUCK (Tadorna ferruginea)

The Ruddy shelduck (Tadorna ferruginea) is a distinctive waterfowl that has a loud honking call. The ruddy shelduck mostly inhabits inland water-bodies and forms a lonf lasting pair bond. In central and eastern Asia, populations of this species are steady or rising, but in Europe, they are generally in decline.

The male Ruddy shelduck has orange-brown body plumage and a paler, orange-brown head and neck, separated from the body by a narrow black collar. The rump, flight feathers, tail-coverts, and tail feathers are black and there are iridescent green speculum feathers on the inner surfaces of the wings. Both upper and lower wing coverts are white, this feature being particularly noticeable in flight but hardly visible when the bird is at rest. The bill is black and the legs are dark grey. The female is similar but has a rather pale, whitish head and neck and lacks the black collar, and in both sexes, the coloring is variable and fades as the feathers age. The birds molt at the end of the breeding season and the male loses the black collar, but a further partial molt between December and April restores it. Juveniles are similar to the female but are a darker shade of brown.

Ruddy shelducks breed from southeast Europe across the Palearctic to Lake Baikal, Mongolia, and western China. There are also very small resident populations of this species in Northwest Africa and Ethiopia. Most populations are migratory, wintering in the Indian subcontinent and breeding in southeastern Europe and central Asia, though there are small resident populations in North Africa. Ruddy shelducks are usually found in open locations on inland bodies of water such as lakes, reservoirs, and rivers. They rarely occur in forested areas but do occur in brackish water and saline lagoons. 

They typically breed in large wetlands and rivers with mud flats and shingle banks, and they are found in large numbers on lakes and reservoirs. They breed in high-altitude lakes and swamps in Jammu and Kashmir. Outside the breeding season, they prefer lowland streams, sluggish rivers, ponds, flooded grassland, marshes, and brackish lagoons.

In Europe, populations of Ruddy shelducks are generally declining as wetlands are drained and the birds are hunted. However, they are less vulnerable than some other waterfowl because they can adapt to new habitats such as reservoirs.

Ruddy shelducks are social birds. They are usually found in pairs or small groups and rarely form large flocks. However, molting and wintering gatherings on chosen lakes or slow rivers can be very large. Ruddy shelducks are active during the night. On land, they graze on the foliage, but when in the water they do not dive; they dabble in the shallows, and at greater depths, they up-end. Ruddy shelducks are very noisy when in flocks. Their call is a series of loud, nasal honking notes. The calls are made both on the ground and in the air, and the sounds are variable according to the circumstances in which they are uttered.

Ruddy shelducks are monogamous a form strong pair bonds that are thought to last for life. The birds arrive at their main breeding grounds in central Asia in March and April. When nesting Ruddy shelducks are very aggressive towards their own kind and towards other species. The female in particular approaches intruders with head lowered and neck outstretched, uttering anger calls. If the intruder stands its ground, the female returns to the male and runs around him, inciting him to attack. He may or may not do so. Courtship ritual includes neck stretching, head dipping, and tail raising. The nesting site is often far away from water in a hole in a tree or ruined building, a crevice in a cliff, among sand dunes, or in an animal burrow. The nest is constructed by the female using feathers and down and some grasses. The female lays 6-12 eggs between late April and early June and incubates them alone while the male stands in attendance nearby. The eggs hatch after about 28 days and both parents care for the young, which fledge in a further 55 days. After breeding the adults moult, losing the power of flight for about a month while they do so. Before molting they move to large water bodies where they can more easily avoid predation while they are flightless. The family may stay together as a group for some time; the autumn migration starts around September and the young may mature in their second year. North African birds usually breed about 5 weeks earlier.

28-11-2016 JURONG, SINGAPORE - NICOBAR PIGEON (Caloenas nicobarica)

The Nicobar pigeon (Caloenas nicobarica) is a large beautiful bird found mainly in South East Asia and Oceania. It is the only living member of the genus Caloenas alongside the extinct Spotted green pigeon and is the closest living relative of the extinct dodo and Rodrigues solitaire.

Nicobar pigeons have developed a bright plumage; their head is grey, like the upper neck plumage, which turns into green and copper hackles. The tail is very short and pure white. The rest of their plumage is metallic green. The cere of the dark bill forms a small blackish knob; the strong legs and feet are dull red. Females are slightly smaller than males; they have a smaller bill knob, shorter hackles, and browner underparts. Immature birds have a black tail and lack almost all iridescence.

Nicobar pigeons are found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Malay Archipelago, to the Solomons and Palau. They inhabit rainforests, dry forests, mangroves, and shrubland.

Nicobar pigeons are highly nomadic and roam in flocks from island to island, usually sleeping on offshore islets where no predators occur; they spend the day in areas with better food availability, not shying away from areas inhabited by humans. Nicobar pigeons are most active at dawn and dusk and prefer to feed singly or in pairs. Although these birds spend most of their time on the forest floor, they are powerful flyers; their flight is quick, with regular beats and an occasional sharp flick of the wings, as is characteristic of pigeons in general. Unlike other pigeons, groups of Nicobar pigeons tend to fly in columns or single file, not in a loose flock. The white tail is prominent in flight when seen from behind and may serve as a sort of "taillight", keeping flocks together when crossing the sea at dawn or dusk. Nicobar pigeons are very vocal birds and in order to communicate with each other, they give a low-pitched repetitive call.

28-11-2016 JURONG, SINGAPORE - MASKED LAPWING (Vanellus miles)

The Masked lapwing (Vanellus miles ) is a large, common, and conspicuous bird. It spends most of its time on the ground and has several distinctive calls. It is common in Australian fields and open land, and is known for its defensive swooping behavior during the nesting season. The species is also known as the Masked plover and often called the Spur-winged plover or just plover in its native range.

The Masked lapwing is the largest representative of the family Charadriidae. It has a conspicuous yellow spur on the carpal joint of each wing. The subspecies from northern Australia and New Guinea (V. m. miles ) have an all-white neck and large yellow wattles with the male having a distinctive mask and larger wattles. The subspecies found in the southern and eastern states of Australia and in New Zealand (V. m. novaehollandiae ), and often locally called the Spur-winged plover, has a black neck-stripe and smaller wattles. (Note that the northern hemisphere Spur-winged plover is a different bird.)

Masked lapwings are native to the northern and eastern parts of Australia, New Zealand, and New Guinea. These birds don’t migrate and prefer to live on the edges of wetlands, and in other moist, open environments. However, they are adaptable and can often be found in surprisingly arid areas, pasturelands, and urban areas.

28-11-2016 JURONG, SINGAPORE - LESSER WHISTLING DUCK (Dendrocygna javanica)

The lesser whistling duck (Dendrocygna javanica ), also known as Indian whistling duck or lesser whistling teal, is a species of whistling duck that breeds in the Indian subcontinent and Southeast Asia. They are nocturnal feeders that during the day may be found in flocks around lakes and wet paddy fields. They can perch on trees and sometimes build their nest in the hollow of a tree. This brown and long-necked duck has broad wings that are visible in flight and produces a loud two-note wheezy call. It has a chestnut rump, differentiating it from its larger relative, the fulvous whistling duck, which has a creamy white rump.

This chestnut brown duck is confusable only with the fulvous whistling duck (D. bicolor ) but has chestnut upper-tail coverts unlike the creamy white in the latter. The ring around the eye is orange to yellow. When flying straight, their head is held below the level of the body as in other Dendrocygna species. The crown appears dark and the sexes are alike in plumage. They fly slowly but with rapid wing-flapping and usually produce a repetitive wheezy seasick call as they circle overhead. They are very nocturnal and often rest during the day. The outermost primary feather has the inner vane modified. They produce very prominent whistling sound while flying.

This is a largely resident species distributed widely across lowland wetlands of the Indian subcontinent and Southeast Asia. The species also occur on islands in the region including the Andamans, Nicobars and Maldives. They sometimes make local movements in response to weather and changes in water availability and the more northern birds winter further south. They are found in freshwater wetlands with good vegetation cover and often rest during the day on the banks or even on the open sea in coastal areas. Downy chicks are black with a white eyebrow and white patches on the back of the head, the wing, lower back and rump. Albino individuals have been seen in the wild.

Large numbers are sometimes found in urban wetlands such as in Kolkata and Goa, particularly during winter. In the Alipore Zoological Gardens, captive individuals were introduced in the 1930s and wild birds joined this nucleus subsequently.

With a wide distribution range between 1 and 10 million km², they are considered to have a secure global population of between two and twenty million individuals. They are not threatened by hunting as they are not considered good to eat. Hunters in Assam however have been known to raise the ducklings to serve as live decoy.

Lesser whistling duck are usually gregarious. They feed mainly on plants taken from the water as well as grains from cultivated rice apart from small fish, frogs and invertebrates such as molluscs and worms. They dabble as well as dive in water. They will often waddle on the land and Common mynas have been noted to follow them on grass. Courtship involves the male facing the female and dipping and raising its bill in the water and swimming around the female. They breed during the monsoon or rainy season and may vary locally in relation to the food availability. The nest site may be a tree hole lined with twigs and grass or built in the fork of a large tree, sometimes reusing an old nest of a kite or heron or even on the ground. The clutch varies from 7 to 12 white eggs that are incubated by both the parents. Large clutches of up to 17 have been noted although these may be indications of intraspecific brood parasitism. The eggs hatch after about 22–24 days. More than one brood may be raised in a single season. Young birds may sometimes be carried on the back of the parents.

Local names like sili and silhahi in India are based on their wheezy two-note calls. They become very tame in captivity, walking about and responding to whistles. Individuals in captivity in the USA have lived for up to 9 years.

Several endoparasitic cestodes including Hymenolepis javanensis and Cittotaenia sandgroundi have been described from lesser whistling duck hosts apart from ectoparasitic bird lice and mites.

28-11-2016 JURONG, SINGAPORE - GREY CROWNED CRANE (Balearica regulorum)

The elegant Grey crowned crane (Balearica regulorum) is one of Africa’s most majestic and beautiful birds. It is the national symbol and the national bird of Uganda. The name is due to its yellow crown of feathers, tipped with black. This crane moves gracefully in a most stately manner with a very dignified gait. In flight it is beautiful, using slow-down strokes followed by quick upward strokes of its wings. The body plumage of this bird is mainly grey. The wings are predominantly white, but contain feathers with a range of colors, with a distinctive black patch at the very top. The head has a crown of stiff golden feathers. The sides of the face are white, and there is a bright red inflatable throat pouch. The bill is relatively short and grey, and the legs are black.

They have long legs for wading through the grasses. The feet are large, yet slender, adapted for balance rather than defense or grasping. The sexes are similar, although males tend to be slightly larger. Younger cranes are greyer than adults, with a feathered buff face.

The Grey crowned crane lives in eastern and southern Africa, from Kenya and Uganda to South Africa and Zimbabwe, frequenting wetlands, savannahs, open grasslands, and cultivated areas. In parts of East Africa, it occurs in modified habitats like pastures, croplands, and other irrigated areas, while in South Africa, it is found in marshes, grasslands, savannahs, and cultivated fields.
