27-10-2016 BEIJING, CHINA - MANDARIN DUCK (MALE) (Aix galericulata)
%20(Aix%20galericulata)%2030.jpg)
The mandarin, widely regarded as the world's most beautiful duck, is a native of China and Japan.
The drake mandarin's stunning plumage has long made it an artist's favourite, and it is widely depicted in oriental art.
The first mandarins were imported to Britain in the mid-18th century, but it wasn't until the 1930s that escapes from wildfowl collections started breeding here.
The first birds to escape did so from Alfred Ezra's collection at Foxwarren Park, near Cobham in Surrey, and this area remains one of the strongholds of mandarins in England.
Mandarins favour small wooded ponds and avoid lakes or large bodies of open water.
They are extremely manoeuvrable fliers, able to fly through trees with remarkable agility.
They frequently perch in trees, while the female invariably chooses a hole or cavity in a tree trunk in which to lay her eggs.

Lack of natural nest sites and competition from jackdaws and squirrels limits population expansion, but they will readily adopt suitable nest boxes.
After hatching, the ducklings jump to the ground: their fluffy down and lightweight ensures that injuries are unusual.
Once the mother has gathered her brood, she leads them straight to water.
It was long believed that the British population - now close to 8,000 birds - was of international importance, but previously undiscovered populations have been discovered in China, so this duck is far more numerous than was once thought.
In their native China mandarins have long been regarded as symbols of fidelity and pairs were given to brides on their wedding day.
In fact mandarins, like most ducks, only pair for the season, and new pairs will form again in the autumn.
The drake mandarin's display is highly ritualised, and includes raising the crest and the orange sails, and ritualised drinking and preening behind the sail.
The so-called sail is an elongated tertial feather.
In eclipse (summer) plumage the drake moults and looks almost identical to the duck, only his bright red beak indicating his sex.
China historically exported hundreds of thousands of mandarins, but the export trade was banned in 1975.
The mandarin is a member of the genus, which has only one other member, the closely related North American wood duck. Though the drakes are very different, the plumage of the females is very similar.
Despite the closeness of the relationship with the wood duck, no hybrids have ever been recorded. This is because the mandarin has a chromosome aberrance that makes it impossible for it to produce hybrids with other ducks.
The mandarin is one of the few introduced species in Britain that has not created any environmental problems, mainly because it uses a habitat not favoured by our native wildfowl.
Female mandarins don't quack, but they do make a series of clucking calls that are invariably uttered when they see danger, such as a hunting fox.
7-11-2016 BANGKOK, THAILAND - 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.

Ipomoea hederifolia is a species of herbaceous annual vine native to the Americas. It was first described by Linnaeus in 1759.
It is commonly known as scarlet morning glory, scarlet creeper, star ipomoea, trompillo or ivy-leaved morning glory (which otherwise refers to I. hederacea).
25-10-2016 SINGAPORE CITY - JAVAN MYNA (Acridotheres javanicus)
The Javan myna (Acridotheres javanicus ), also known as the white-vented myna, is a species of myna. It is a member of the starling family. It is native to Bali and Java. It has been introduced to other Asian countries, and as far away as Puerto Rico.
The Javan myna is mainly black. The wings are brownish-black, and the primaries have white bases. The undertail-coverts are white. There is a short crest on the forehead.Its beak, legs and feet are yellow. The eyes are lemon-yellow. The immature is browner. Its length is 21–23 cm (8.3–9.1 in). Its weight is about 100 g (3.5 oz).
The Javan myna is native to Bali and Java, and has been introduced to southeastern Thailand, southern Malaysia, Singapore, Sumatra, the Lesser Sundas, Taiwan, Puerto Rico, Japan and Nepal. It is found in cities and cultivated areas.
The Javan myna is omnivorous and eats seeds, fruit, nectar, insects and human waste. It is often found in large groups. Its voice is similar to that of the common myna. It builds its nest in holes. The eggs are bluish-glaucous. Javan mynas are bold and not very afraid of humans. Javan mynas are kept in cages in Malaysia and Indonesia. The birds scavenge in groups, minimum two but usually three or more, with all except one feeding and one usually at a vantage point keeping a look out. If the bird that is keeping watch sees anything that might pose a threat, it alarms the group members with a high pitch tweet and they all flee the area swiftly.
29-11-2016 GARDENS OF THE BAY, SINGAPORE - TREE CRINUM (Crinum asiaticum)
Crinum asiaticum, commonly known as poison bulb, giant crinum lily, grand crinum lily, or spider lily, is a plant species widely planted in many warmer regions as an ornamental. It is a bulb-forming perennial producing an umbel of large, showy flowers that are prized by gardeners. However, all parts of the plant are poisonous if ingested. Some reports indicate exposure to the sap may cause skin irritation.
Crinum asiaticum is native to East Asia, tropical Asia, Australia and islands of the Pacific and western Indian oceans. It is naturalized in Mexico, the West Indies, the US (Florida and Louisiana), numerous Pacific islands, Madagascar and the Chagos Archipelago.
Crinum asiaticum is a perennial herb that typically grows up to 1.2 m (3.9 ft) tall. It has a leaf base. Its pseudobulb is spherical. The upper part of the bulb is cylindrical. The base is laterally branched, with a diameter of about 6–15 cm. Its leaves are lanceolate, margin undulate, apically acuminate. They feature 1 sharp point and are dark green, growing up to 1 m long. Their width is 7–12 cm or wider and they number 20-30. The inflorescence is an umbel with 10-24 flowers, six petaloid tepals, and aromatic. The flower stem is erect, as long as the leaf, and solid. The spathe is lanceolate, membranous, and 6–10 cm. The bractlet liner is 3–7 cm. Its perianth tube is slender and straight, green white, 7–10 cm, diameter 1.5–2 mm. The corolla is spider-like shaped, white, linear, revolute, attenuate, 4.5–9 cm long, and 6–9 mm wide. The corolla is 6-lobed. The pedicel is ca 0.5-2.5 cm long. It has 6 reddish stamens.

28-11-2016 JURONG, SINGAPORE - SCARLET IBIS (Eudocimus ruber)
28-11-2016 JURONG, SINGAPORE - AFRICAN PENGUIN (Spheniscus demersus)
The African penguin (Spheniscus demersus) is a species of penguin that lives in southern African waters. Like all extant penguins, it is flightless and adapted for a marine habitat. Once extremely numerous, the African penguin is declining rapidly due to a combination of several threats and is classified as endangered. It is a charismatic species and is popular with tourists.
The African penguin is a small to medium-sized penguin with black-and-white plumage, serving the animal as a perfect camouflage to protect it from predators. Due to the black feathers on their back, they merge with the environment, remaining unseen to those looking down from above. Meanwhile, the white coloration on the front part of their body allows them to be unspotted by aquatic predators, looking up from below. The penguins have a horseshoe-shaped, white-colored stripe on their face, stretching from around their eyes to their chest as well on the chin, towards the bill. Young penguins possess gray-blue feathers, which darken as they grow up.
African penguins are found along the coast of South Africa and Namibia. They do not migrate and live in colonies on 24 islands between Namibia and Algoa Bay, near Port Elizabeth, South Africa. African penguins spend most of their lives at sea and come ashore to breed and molt.
African penguins are both diurnal and crepuscular. By day, the birds hide in their burrows, escaping the sun. At twilight and dawn, they come out to forage. African penguins are highly social animals. Grooming is a common activity in these animals. They groom each other in order to clean the plumage, rearrange the feathers and take off parasites. In addition, grooming reinforces the social bond between a pair. During their courtship rituals, the birds are extremely noisy, emitting loud calls, which are quite similar to these of donkeys. In order to clean and cool themselves, they frequently take baths, making their bathing spots at a distance of just a few meters from the seashore.
These birds are monogamous, mating once in a lifetime. They can use the same breeding sites for many years. African penguins breed all year round with the peak period, occurring in February. Usually, the female digs a burrow or simply uses a hollow under a rock or bush, where she lays 2 eggs, after which both the male and the female incubate the eggs for up to 40 days. During the first month after hatching out, the chicks are fed and cared by both parents. Then they join crèches or groups of other chicks, where they find protection from predators. The chicks stay with their parents, until the age of 3-5 months, after which they leave the colony and start living independently. Male penguins become reproductively mature at 5 years old while females start to breed when they are 4 years old.
Commercial fishing negatively affects the population of the species, reducing prey items and leading to food shortages. Meanwhile, the African penguins compete with Cape Fur Seals for breeding areas as well as prey items. On the other hand, the penguins are threatened by their natural predators. For example, they are prey species for seals, while their eggs and chicks are a source of food for other predators in the area. In addition, these birds currently suffer from oil pollution.
29-11-2016 GARDENS OF THE BAY, SINGAPORE - CANNA LILIES (Genus Canna)
Canna or canna lily is the only genus of flowering plants in the family Cannaceae, consisting of 10 species. All of the genus's species are native to the American tropics and naturalized in Europe, India and Africa in the 1860s. Although they grow native to the tropics, most cultivars have been developed in temperate climates and are easy to grow in most countries of the world, as long as they receive at least 6–8 hours average sunlight during the summer, and are moved to a warm location for the winter. See the Canna cultivar gallery for photographs of Canna cultivars.
Cannas are not true lilies, but have been assigned by the APG II system of 2003 to the order Zingiberales in the monocot clade Commelinids, together with their closest relatives, the gingers, spiral gingers, bananas, arrowroots, heliconias, and birds of paradise.
The plants have large foliage, so horticulturists have developed selected forms as large-flowered garden plants. Cannas are also used in agriculture as a source of starch for human and animal consumption. C. indica and C. glauca have been grown into many cultivars in India and Africa.
29-11-2016 GARDEN BY THE BAY, SINGAPORE - BEACH SPIDER LILY (Hymenocallis littoralis)

Hymenocallis is derived from Greek and means 'membraned beauty', a reference to its filament cup.
Littoralis means 'growing by the seashore'.
Hymenocallis littoralis is a bulbous perennial herb. It ranges in height from 60–70 cm (24-28 inches). The bulb is 7–10 cm (3-4 inches) in diameter. With age, the bulb develops a neck that reaches 4–5 cm in diameter (up to 2 inches). The flowers are large, white, vanilla scented, and sessile. The tepals are adnate (attached to) the staminal cup. Each flower's tube is 14 to 17 cm (5 to 7 inches) long or longer.
Hymenocallis littoralis is regarded as native to Belize, Brazil, Colombia, Costa Rica, Honduras, Mexico, Nicaragua, Panama, Peru and Venezuela.
