4-12-2015 JURONG, SINGAPORE - SILVER PHEASANT (FEMALE) (Lophura nycthemera)
%2010.jpg)
The silver pheasant (Lophura nycthemera) is a species of pheasant found in forests, mainly in mountains, of mainland Southeast Asia and eastern and southern China, with an introduced population on Victoria Island in Nahuel Huapi Lake, Neuquén, Argentina. The male is black and white, while the female is mainly brown. Both sexes have a bare red face and red legs (the latter separating it from the greyish-legged kalij pheasant). It is common in aviculture, and overall also remains common in the wild, but some of its subspecies (notably L. n. whiteheadi from Hainan, L. n. engelbachi from southern Laos, and L. n. annamensis from southern Vietnam) are rare and threatened.

This is a relatively large pheasant, with males of the largest subspecies having a total length of 120 to 125 cm (47 to 49 in), including a tail up to 75 cm (30 in), while the males of the smallest subspecies barely reach 70 cm (28 in) in total length, including a tail around 30 cm (12 in). The body mass of males can range from 1.13–2.00 kg (2.49–4.41 lb). Females of all subspecies are notably smaller than their respective males, with a size range of 55–90 cm (22–35 in) in total length, including a tail of 24–32 cm (9.4–12.6 in). The body mass of females can range from 1.0–1.3 kg (2.2–2.9 lb).
Males of the northern subspecies, which are the largest, have white upperparts and tail (most feathers with some black markings), while their underparts and crest are glossy bluish-black. The males of the southern subspecies have greyer upperparts and tail with extensive black markings, making them appear far darker than the northern subspecies. The adult male plumage is reached in the second year.
Females are brown and shorter-tailed than males. Females of some subspecies have whitish underparts strongly patterned with black, and in L. n. whiteheadi this extends to the upper mantle.
4-12-2015 JURONG, SINGAPORE - NICOBAR PIGEON (Caloenas nicobarica)
%2010.jpg)
The Nicobar pigeon or Nicobar dove (Caloenas nicobarica, Car: ma-kūö-kö[3]) is a bird found on small islands and in coastal regions from the Andaman and Nicobar Islands, India, east through the Indonesian Archipelago, to the Solomons and Palau. It is the only living member of the genus Caloenas alongside the extinct spotted green pigeon and Kanaka pigeon, and is the closest living relative of the extinct dodo and Rodrigues solitaire.
%2011.jpg)
It is a large pigeon, measuring 40 cm (16 in) in length. The 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 its plumage is metallic green. The cere of the dark bill forms a small blackish knob; the strong legs and feet are dull red. The irises are dark.

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. There is hardly any variation across the birds' wide range. Even the Palau subspecies C. n. pelewensis has merely shorter neck hackles, but is otherwise almost identical.
It is a very vocal species, giving a low-pitched repetitive call.
On the Nicobar Islands (which are referred to in its common and scientific names), the most significant colony of Nicobar pigeons in modern times was found on Batti Malv, a remote wildlife sanctuary between Car Nicobar and Teressa. The 2004 Indian Ocean tsunami caused massive damage on the Nicobar Islands, and to what extent Batti Malv was affected is still not clear. But while everything on some islets in the Great Nicobar Biosphere Reserve was destroyed, Batti Malv lighthouse – a skeletal tower a dozen metres high, standing a few metres ASL at the highest point of the low-lying island – was little-damaged and put back in operation by the survey ship INS Sandhayak less than one month after the disaster. An April 2007 survey by the Indian Coast Guard vessel ICGS Vikram found the lighthouse tower "totally covered" in vines, indicating rampant regeneration of vegetation – but perhaps also that damage to the island's forest was severe, as a cover of creeping plants is typical of early succession stages, while a photo of the lighthouse taken before the tsunami shows rather mature forest.

The Nicobar pigeon's breeding range encompasses the Andaman and Nicobar Islands of India, the Mergui Archipelago of Myanmar, offshore islands of south-western Thailand, Peninsular Malaysia, southern Cambodia and Vietnam, and many of the small islands between Sumatra, the Philippines and the Solomon Islands. On Palau, the only distinct subspecies C. n. pelewensis is found.
The Nicobar pigeon roams in flocks from island to island, usually sleeping on offshore islets where no predators occur and spends the day in areas with better food availability, not shying away from areas inhabited by humans. Its food consists of seeds, fruit and buds, and it is attracted to areas where grain is available. A gizzard stone helps to grind up hard food items. Its 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 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. The young birds' lack of a white tail is a signal of their immaturity clearly visible to conspecifics – to an adult Nicobar pigeon, it is obvious at a glance which flockmembers are neither potential mates, nor potential competitors for mates, nor old enough to safely guide a flock from one island to another.
This species nests in dense forest on offshore islets, often in large colonies. It builds a loose stick nest in a tree. It lays one elliptical faintly blue-tinged white egg.
In 2017, several individual Caloenas nicobarica were sighted in the Kimberley region of Western Australia with a juvenile captured at Ardyaloon (One Arm Point), near Broome - the first time the bird has been sighted on the Australian mainland.
4-12-2015 JURONG, SINGAPORE - INDIAN PIED MYNA (Gracupica contra)
%2010.jpg)
The Indian pied myna (Gracupica contra) is a species of starling found in the Indian subcontinent. It is usually found in small groups mainly on the plains and low foothills. It is often seen within cities and villages although it is not as bold as the common myna. It produces a range of calls made up of liquid notes.
The species is found mainly in the plains but in the foothills up to about 700m above sea level. They are found mainly in areas with access to open water. Their main distribution in India is from the Gangetic plains extending south to the Krishna River. Their range is increasing, with populations establishing more recently in Pakistan, Rajkot, and Bombay (since 1953), possibly aided by trade in caged birds and accidental escape. Their westerward spread in India particularly in parts of Rajasthan has been aided by changes in irrigation and farming patterns. The species has also established itself in Dubai, UAE.
The habitat is lowland open areas with scattered trees near water, often near human habitation. This species is often seen at sewage farms and refuse tips.
4-12-2015 JURONG, SINGAPORE - WHITE CRESTED LAUGHING THRUSH (Garrulax leucolophus)
%2010.jpg)
The white-crested laughingthrush (Garrulax leucolophus) is a member of the family Leiothrichidae. It is a highly social and vocal bird found in forest and scrub from the Himalayan foothills to Southeast Asia.
The white-crested laughingthrush is a popular caged bird species, and it is likely that individuals which escaped or were voluntarily released during religious practices are the cause for the expansion of G. l. diardi's range to Malaysia and Singapore in the 1970s–1980s. The exotic bird trade has brought it to the UK and US as well, but no wild populations have been reported there.

3-1-2016 HONG KONG - YELLOW FACED MYNA (Mino dumontii)
This myna is endemic to New Guinea. As well as being present on the mainland, its range extends to many of the smaller offshore islands. It is common over much of its range at altitudes of up to about 800 metres (2,600 ft) and even higher in parts of Papua New Guinea. It is not present on the southeastern coast of the mainland however. Its typical habitats include rainforests, forest fringes, partially cut areas, secondary growth and gallery forests, and it is sometimes present in savannah areas.
M. dumontii is sometimes seen in small groups but is more often found in pairs. It occasionally forms larger flocks, and communal roosts in tall trees have been described, containing over two hundred birds. It is a noisy bird, emitting a variety of "nasal, growling, and croaking calls with a sometimes human-like conversational quality". It often perches in an elevated position, calling loudly. It has a quick wing-beat and a direct flight, and pairs of birds are often seen flying together; it is possible that this species is monogamous and pairs for life.
This bird is usually found high in the canopy feeding mainly on berries and fruit, although it also feeds on small invertebrates, and it has been observed catching insects in flight. It breeds in holes and crevices in trees well above the ground. The nests are formed of twigs and one or two pale blue eggs speckled with grey and rust are laid. Three birds have been observed carrying nesting material into a single hole, so it is possible that there is some degree of cooperation from the extended family.
