3-12-2015 JURONG, SINGAPORE - ASIAN GLOSSY STARLING (JUVENILE) (Aplonis panayensis)

The Asian glossy starling (Aplonis panayensis) is a species of starling in the family Sturnidae. It is found in Bangladesh, Brunei, India, Indonesia, Malaysia, Myanmar, the Philippines, Singapore, Taiwan (introduced) and Thailand. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest. There is also a huge number of this species inhabiting towns and cities, where they take refuge in abandoned buildings and trees. They often move in large groups and are considered one of the noisiest species of birds. In the Philippines, it is known as kulansiyang, galansiyang, or kuling-dagat.

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend is not known, but the population is not believed to be decreasing sufficiently rapidly to approach the thresholds under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

Fierce-looking, large songbird with a thick, decurved bill. Adult dark with greenish gloss in good light. Juvenile dark gray-brown above with a heavily streaked white belly. Most have ruby-red eyes, but birds in the central and southern Nicobar Islands have pale irises. Prefers urban and suburban areas; a common sight in cities, towns, parks, and farmland areas. Frequently seen perching on telephone wires, fence posts, and buildings, often in very large, noisy flocks. Native to Southeast and South Asia; introduced to Taiwan, where fairly common.

3-12-2015 JURONG, SINGAPORE - RED WHISKERED BULBUL (Pycnonotus jocosus)

The red-whiskered bulbul (Pycnonotus jocosus), or crested bulbul, is a passerine bird native to Asia. It is a member of the bulbul family. It is a resident frugivore found mainly in tropical Asia. It has been introduced in many tropical areas of the world where populations have established themselves. It has a loud three or four note call, feeds on fruits and small insects and perches conspicuously on trees. It is common in hill forests and urban gardens.

The red-whiskered bulbul was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Lanius jocosus. The specific epithet is from Latin ioculus meaning "merry" (from iocus meaning "joke"). Linnaeus based his description on the Sitta Chinensis that had been described in 1757 by the Swedish naturalist Pehr Osbeck. Linnaeus specified the location as "China" but this was restricted to Hong Kong and Guangdong by Herbert Girton Deignan in 1948. The red-whiskered bulbul is now placed in the genus Pycnonotus that was introduced by the German zoologist Friedrich Boie in 1826.

Hybrids have been noted in captivity with the red-vented, white-eared, white-spectacled, black-capped and Himalayan bulbuls. Leucism has also been recorded.

The red-whiskered bulbul is about 20 centimetres (7.9 in) in length. It has brown upper-parts and whitish underparts with buff flanks and a dark spur running onto the breast at shoulder level. It has a tall pointed black crest, red face patch and thin black moustachial line. The tail is long and brown with white terminal feather tips, but the vent area is red. Juveniles lack the red patch behind the eye, and the vent area is rufous-orange.

The loud and evocative call is a sharp kink-a-joo (also transcribed as pettigrew or kick-pettigrew or pleased to meet you and the song is a scolding chatter. They are more often heard than seen, but will often perch conspicuously especially in the mornings when they call from the tops of trees. The life span is about 11 years.

This is a bird of lightly wooded areas, more open country with bushes and shrubs, and farmland. Irruptions have been noted from early times with Thomas C. Jerdon noting that they were "periodically visiting Madras and other wooded towns in large flocks."

It has established itself in Australia and in Los Angeles, Hawaii, and Florida in the United States, as well as in Mauritius, on Assumption Island and Mascarene Islands. In Florida, it is only found in a small area, and its population could be extirpated easily. It was eradicated from Assumption Island in 2013–2015 to prevent colonisation of nearby Aldabra, the largest introduced bird-free tropical island.

The red-whiskered bulbul was introduced by the Zoological and Acclimatization Society in 1880 to Sydney, became well established across the suburbs by 1920, and continued to spread slowly to around 100 km away. It is now also found in suburban Melbourne and Adelaide, although it is unclear how they got there.

On the island of Réunion, this species established itself and also aided the spread of alien plant species such as Rubus alceifolius. In Florida they feed on fruits and berries of as many as 24 exotic plants including loquat (Eriobotrya japonica), Lantana spp., Brazilian pepper (Schinus terebinthifolius) and figs (Ficus). In Mauritius they aid the dispersal of Ligustrum robustum and Clidemia hirta. Seeds that pass through their gut germinate better. Populations of the red-whiskered bulbul on the island of Réunion have diversified in the course of thirty years and show visible variations in bill morphology according to the food resources that they have adapted to utilize.

The red-whiskered bulbul feeds on fruits (including those of the yellow oleander that are toxic to mammals), nectar and insects.

3-12-2015 JURONG, SINGAPORE - PURPLE STARLING (Lamprotornis purpureus)

The purple starling (Lamprotornis purpureus), estorninho azul(argentina, peru, colombia), melro metálico (brazil) also known as the purple glossy starling, is a member of the starling family of birds.

It is a resident breeder in tropical Africa from Senegal and north Zaire east to Sudan and west Kenya. This common passerine is typically found in open woodland and cultivation.

The adults of these stocky 22–23 cm long birds have a metallic purple head and body, and glossy green wings. They have a short tail and a yellow eye. The sexes are similar, but juveniles are much duller, with grey underparts and a brown iris.

This is a gregarious and noisy bird, with typical starling squeaks and chattering.

The purple starling builds a nest in a hole. The normal clutch is two eggs.

Like most starlings, the purple starling is omnivorous, eating fruit and insects.

A chunky, large, short-tailed starling. Mostly iridescent purple, with a greenish back and a huge yellow-orange eye. Found in a wide variety of savanna habitats, from moist broadleaf woodland to dry thorn savanna and thornscrub. Usually in flocks, which can be large and often include other species of starlings. Similar to other savanna-dwelling starlings, but easily separated by the huge eye and the abundance of purple in the plumage. The vocalizations include liquid swirling calls, nasal squeals, and simple chatters.

3-12-2015 JURONG, SINGAPORE - YELLOW BIBBED LORY (Lorius chlorocercus)

4-12-2015 JURONG, SINGAPORE - MANDARIN DUCK (FEMALE) (Aix galericulata)

The mandarin duck (Aix galericulata) is a perching duck species native to the East Palearctic. It is sexually dimorphic, males showing a dramatic difference from the females. It is medium-sized, at 41–49 cm (16–19 in) long with a 65–75 cm (26–30 in) wingspan. It is closely related to the North American wood duck, the only other member of the genus Aix. 'Aix' is an Ancient Greek word which was used by Aristotle to refer to an unknown diving bird, and 'galericulata' is the Latin for a wig, derived from galerum, a cap or bonnet. Outside of its native range, the mandarin duck has a large introduced population in the British Isles and Western Europe, with additional smaller introductions in North America.

The mandarin duck is among the more diminutive types of waterfowl, with a shorter height and smaller overall body size than the dabbling ducks, and is slightly smaller than its American wood duck relatives. The adult male has a petite, red bill, large white crescent above the eye and reddish face and "whiskers". The male's breast is purple with two vertical white bars, the flanks ruddy, and he has two orange feathers at the back (large feathers that stick up similar to boat sails). The female is similar to the female wood duck, with a grayish-lavender tone to her plumage, and a white eye-ring and stripe running back from the eye. The female is paler on the underside, has a small white flank stripe, and a pale tip to its bill.

Both the males and females have crests, but the purple crest is more pronounced on the male.

3-12-2015 JURONG, SINGAPORE - SPOTTED WHISTLING DUCK (Dendrocygna guttata)

The spotted whistling duck (Dendrocygna guttata) is a member of the duck family Anatidae. It is also referred to as the "spotted tree duck". This duck can be found in Indonesia, New Guinea, Australia and the Philippines. Spotted ducks are also held in captive populations.

The Spotted whistling duck is one of the smaller species in the genus Dendrocygna. This duck grows to 43–50 cm tall. Males can weigh anywhere from 590g to 650g while females weigh 610g to 860g. White spots on their flanks and breasts gave these ducks the spotted name. The sides of the neck, faces, and eyebrows are all grey. Black or dark brown coloring stretches from the crown nape to the hindneck. This dark coloring is also found in the eyepatch. Their coloring resembles a cape with a thick collar. This cape starts as a light brown then fades into a darker brown closer to the tail. Their underbelly is mostly brown, sometimes spotted, and significantly lighter than the wings and the “collar.” A white bar on the upper tail coverts can be seen during flight aiding in identification. They have dull pink legs with black webbed feet and sharp nails. The bill is dark, yet often seen with portions of red and a small white mark on the lower mandible. Spotted whistling ducks look as though they are raised from the ground, as though they are standing up tall. (look more into this). Their wings pressed strongly against the body. Inner vanes of the outer primaries are jagged and can be seen in flight (check on this). While flying, the head is positioned down causing the whole bird to look hunched. The tail stays pointed and looks long when in flight. Juveniles are seen with white streaks on flanks instead of spots and have significantly duller coloring. Spotted whistling ducks are visually similar to D. arborea, yet many scientists believe its closest relative is D. eytoni. After gaining their adult plumage at the age of 6 months,. the spotted whistling duck has a single annual molt. Like other ducks, swans, and geese, the spotted whistling duck molts synchronously. Synchronous molting is common within Anseriformes because waterfowl have the ability to avoid terrestrial predators. Unlike other birds, waterfowl float in ponds lakes while they molt, safe from predators. Other more evolved ducks have two molts, whistling ducks only molt once.

3-12-2015 JURONG, SINGAPORE - BLUE FACED HONEYEATER (Entomyzon cyanotis)

The blue-faced honeyeater (Entomyzon cyanotis), also colloquially known as the Bananabird, is a passerine bird of the honeyeater family, Meliphagidae. It is the only member of its genus, and it is most closely related to honeyeaters of the genus Melithreptus. Three subspecies are recognised. At around 29.5 cm (11.6 in) in length, the blue-faced species is large for a honeyeater. Its plumage is distinctive, with olive upperparts, white underparts, and a black head and throat with white nape and cheeks. Males and females are similar in external appearance. Adults have a blue area of bare skin on each side of the face readily distinguishing them from juveniles, which have yellow or green patches of bare skin.

Found in open woodland, parks and gardens, the blue-faced honeyeater is common in northern and eastern Australia, and southern New Guinea. It appears to be sedentary in parts of its range, and locally nomadic in other parts; however, the species has been little studied. Its diet is mostly composed of invertebrates, supplemented with nectar and fruit. They often take over and renovate old babbler nests, in which the female lays and incubates two or rarely three eggs.

The blue-faced honeyeater is found from the Kimberleys in northwestern Australia eastwards across the Top End and into Queensland, where it is found from Cape York south across the eastern and central parts of the state, roughly east of a line connecting Karumba, Blackall, Cunnamulla and Currawinya National Park. It has a patchy distribution in New South Wales, occurring in the Northern Rivers and Northern Tablelands regions, and along the coast south to Nambucca Heads. To the south, it is generally absent from the Central and South Coast, and is instead found west of the Great Divide across the South West Slopes and Riverina to the Murray River. It is common in northern Victoria and reaches Bordertown in southeastern South Australia, its range continuing along the Murray. It is also found in the Grampians region, particularly in the vicinity of Stawell, Ararat and St Arnaud, with rare reports from southwestern Victoria. The species occasionally reaches Adelaide, and there is a single record from the Eyre Peninsula. The altitude ranges from sea level to around 850 m (2,790 ft), or rarely 1,000 m (3,300 ft).

In New Guinea, it is found from Merauke in the far southeast of Indonesia's Papua province and east across the Trans-Fly region of southwestern Papua New Guinea. It has also been recorded from the Aru Islands.

The blue-faced honeyeater appears to be generally sedentary within its range, especially in much of the Northern Territory, Queensland and New South Wales. However, in many places (generally south of the Tropic of Capricorn), populations may be present or absent at different times of the year, although this appears to result from nomadic, rather than seasonal, migratory movements. Around Wellington in central New South Wales, birds were recorded over winter months, and were more common in autumn around the Talbragar River. Birds were present all year round near Inverell in northern New South Wales, but noted to be flying eastwards from January to May, and westwards in June and July. In Jandowae in southeastern Queensland, birds were regularly recorded flying north and east from March to June, and returning south and west in July and August, and were absent from the area in spring and summer.

They live throughout rainforest, dry sclerophyll (Eucalyptus) forest, open woodland, Pandanus thickets, paperbarks, mangroves, watercourses, and wetter areas of semi-arid regions, as well as parks, gardens, and golf courses in urban areas. The understory in eucalypt-dominated woodland, where the blue-faced honeyeater is found, is most commonly composed of grasses, such as Triodia, but sometimes it is made up of shrubs or small trees, such as grevilleas, paperbarks, wattles, Cooktown ironwood (Erythrophleum chlorostachys) or billygoat plum (Terminalia ferdinandiana). One study in Kakadu National Park found that blue-faced honeyeaters inhabited mixed stands of eucalypts and Pandanus, but were missing from pure stands of either plant.

3-12-2015 SINGAPORE - WHITE CROWNED ROBIN CHAT (Cossypha albicapillus)

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.

Although widespread, very little is known about the White-crowned Robin Chat. Neither population nor breeding information information is available. Taxonomically, robin chats were once thought to belong to the Thrush family. However recent studies have shown that they are more closely related to the Old World flycatchers.

Widespread this species inhabit eleven countries in the northern part of Africa. Although there have been no formal population studies the white-crowned robin chat is quite common throughout its range.

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.

3-12-2015 JURONG, SINGAPORE - SILVER PHEASANT (Lophura nycthemera)

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 introduced populations in Hawaii and various locations in the US mainland. 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.

1-12-2015 ANGKOR WAT, CAMBODIA - GREAT MORMON BUTTERFLY (Papilio memnon)

Papilio memnon, the great Mormon, is a large butterfly native to southern Asia that belongs to the swallowtail family. It is widely distributed and has thirteen subspecies. The female is polymorphic and with mimetic forms.

Its range includes north-eastern India (including Sikkim, Assam and Nagaland), Nepal, Bangladesh, Myanmar, Nicobar Islands, Andaman Islands (stragglers only), western, southern and eastern China (including Hainan), Taiwan, southern Japan including Ryukyu Islands, Thailand, Laos, Vietnam, Kampuchea, Malaysia and Indonesia (Sumatra, Mentawai Islands, Nias, Batu, Simeulue, Bangka, Java, Kalimantan and the Lesser Sunda Islands).

This species is common and not threatened. The cultivation of citrus all over Southern Asia provides an abundance of food plants.

The butterfly is large with a 120 to 150 millimetres (4.7 to 5.9 in) span. It has four male and many female forms, the females being highly polymorphic and many of them being mimics of unpalatable butterflies. This species has been studied extensively for understanding the genetic basis for polymorphy and Batesian mimicry. As many as twenty-six female forms are reported.

This species flies up to 2,100 metres (6,900 ft) in the Himalayas, but is most common at low elevations.

This butterfly is found in forest clearings. It is very common and is also seen amongst human habitation. It visits flowers of Poinsettia, Jasminum, Lantana, Canna and Salvia. It usually flies 2 to 4 metres (6 ft 7 in to 13 ft 1 in) above the ground. The butterfly is known to mud-puddle. The males are much more common than females. The female forms butlerianus and alcanor are especially uncommon.
