26-11-2015 JURONG, SINGAPORE - SUPERB STARLING (Lamprotornis superbus)
%2010.jpg)
The superb starling (Lamprotornis superbus) is a member of the starling family of birds. It was formerly known as Spreo superbus. They are long-lived birds that can live over 15 years in captivity.
This species is 18 to 19 cm (7.1 to 7.5 in) in height. These small short-tailed starlings have a long narrow bill, robust bodies, strong feet and a distinctive plumage pattern. Their spectacular iridescent plumage is due to the arrangement of melanin granules within the feathers, resulting in structural blues and greens, rather than colors derived from pigments. The appearance of the superb starling is very similar to the Hildebrandt's starling, also found in East Africa. The superb starling is distinguished by having pale creamy-white eyes, as opposed to red eyes in the Hildebrandt's. Moreover, only adult superb starlings have a white breast band.

The superb starling lives in the savanna, thornbush and acacia arid areas, open woodland, lakeshore woodlands, gardens and cultivated fields, at an elevation of 0–2,650 metres (0–8,694 ft) above sea level. They tend to avoid humid lowland areas. This species has a very large range and can commonly be found in East Africa, including Ethiopia, Somalia, Uganda, Kenya, South Sudan, and Tanzania. Superb Starlings typically occupy large territories, often exceeding 50 hectares (0.50 km2). When they are not on their territories, they are usually searching for food or heading to water sources. Their group can have more than 40 individuals. The sex ratio in those is approximately equal. In the non-breeding season, being the dry season, the groups of superb starlings live with other starling species such as the Hildebrandt’s starling (Lamprotornis hildebrandti) and the greater blue-eared glossy starling (Lamprotornis chalybaeus). They have also been observed with other bird species such as the red-billed buffalo weaver (Bubalornis niger) and the white-headed buffalo weaver (Dinemellia dinemellii) in the Serengeti National Park, in Tanzania. Mixed species flocks might aid in obtaining food and serve as a defense mechanism against predators. When it is the breeding season however, the superb starlings are territorial and chase the birds of other species from the group, especially when they approach their nests.

13-12-2015 YANGON, MYANMAR - ROCK PIGEON (Columba livia)
%2010.jpg)
The rock dove, rock pigeon, or common pigeon (/ˈpɪdʒ.ən/ also /ˈpɪdʒ.ɪn/; Columba livia) is a member of the bird family Columbidae (doves and pigeons).: 624 In common usage, it is often simply referred to as the "pigeon", although this is the wild form of the bird; the pigeons most familiar to people are the domesticated form of the wild rock dove.
The domestic pigeon (Columba livia domestica, which includes about 1,000 different breeds) descended from this species. Escaped domestic pigeons have increased the populations of feral pigeons around the world.
Wild rock doves are pale grey with two black bars on each wing, whereas domestic and feral pigeons vary in the colour and pattern of their plumage. Few differences are seen between males and females; i.e they are not strongly sexually dimorphic. The species is generally monogamous, with two squabs (young) per brood. Both parents care for the young for a time.
Habitats include various open and semi-open environments where they are able to forage on the ground. Cliffs and rock ledges are used for roosting and breeding in the wild. Originating in Southern Europe, North Africa, and Western Asia, pigeons have become established in cities around the world. The species is abundant, with an estimated population of 17 to 28 million feral and wild birds in Europe alone and up to 120 million worldwide.
26-11-2015 JURONG, SINGAPORE - GREATER FLAMINGO (Phoenicopterus roseus)
It is found in parts of Northern Africa (including coastal areas of northern Algeria, Egypt further inland along the Nile River, Libya, Morocco, and Tunisia), portions of Sub-Saharan Africa (Kenya, Madagascar, Rwanda, Tanzania, Uganda), Southern Asia (coastal Bangladesh, Pakistan, India, and Sri Lanka), the Middle East (Bahrain, Cyprus, Iraq, Iran, Oman, Israel, Kuwait, Lebanon, Qatar, and the United Arab Emirates) and Southern Europe (including Albania, Bulgaria, Corsica, Croatia, France in the Camargue, Greece, Italy, Slovenia, Malta, Monaco, Montenegro, North Macedonia, Portugal, Spain and the Balearic Islands, and Turkey. The most northern breeding spot is the Zwillbrocker Venn in western Germany, close to the border with the Netherlands. They have been recorded breeding in the United Arab Emirates at three different locations in the Abu Dhabi Emirate. In Gujarat, a coastal state in the west of India, flamingos can be observed at the Nal Sarovar Bird Sanctuary, Khijadiya Bird Sanctuary, Flamingo City, and in the Thol Bird Sanctuary. They remain there during the entire winter season.

The greater flamingo resides in mudflats and shallow coastal lagoons with salt water. Using its feet, the bird stirs up the mud, then sucks water through its bill and filters out small shrimp, seeds, blue-green algae, microscopic organisms, and mollusks. The greater flamingo feeds with its head down, its upper jaw movable and not rigidly fixed to its skull.
Like all flamingos, this species lays a single chalky-white egg on a mud mound.
The typical lifespan in captivity, according to Basel Zoo, is over 60 years. In the wild, the average lifespan is 30 – 40 years.
Adult greater flamingos have few natural predators. Eggs and chicks may be eaten by raptors, crows, gulls, and the marabou stork (Leptoptilos crumenifer); an estimated half of the predation of greater flamingo eggs and chicks is from the yellow-legged gull (Larus michahellis).
26-11-2015 BOTANICAL GARDENS, SINGAPORE - ZEBRA DOVE (Geopelia striata)
%2010.jpg)
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, 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. In Malaysia this bird is called merbuk.

26-11-2015 BOTANICAL GARDENS, SINGAPORE - ASIAN HOUSE GECKO (Hemidactylus frenatus)
The common house gecko is prolific through the tropics and subtropics. It is able to exist in an ecologically analogous place with other Hemidactylus species. Despite being native throughout Southeast Asia, recent introductions, both deliberate and accidental, have seen them recorded in the Deep South of the United States, large parts of tropical and sub-tropical Australia, and many other countries in South and Central America, Caribbean Dominican Republic, Africa, South Asia and the Middle East (Bahrain, Jordan, Qatar, Kuwait, Saudi Arabia, Oman and the United Arab Emirates). Most recently, this species has also invaded the Caribbean Lesser Antilles, and is now present on Saint Martin (island), Saint Barthélemy, Sint Eustatius, Dominica and Saint Lucia. Their capacity to withstand a wide range of latitudes is also partially facilitated by their capacity to enter a state of brumation during colder months. The prospect of increased climate change interacts synergistically with increased urbanisation, greatly increasing the prospective distribution of the common house gecko. Due to concerns over its potential capacity as an invasive species, there are efforts to limit their introduction and presence in locations where they could be a risk to native gecko species.
In Mexico, H. frenatus was first collected in Acapulco, Guerrero, in March of 1895 and found to be well established there and in the surrounding regions by the early 1940s. It was likely introduced through shipping and cargo. H. frenatus now occurs throughout the lowlands of Mexico on both the Atlantic and Pacific versants including the Yucatan Peninsula, and Baja California, with records from 21 of the 32 Mexican states. Most records of H. frenatus in Mexico are from buildings such as homes, hotels, and other structure in cities and towns, with only a few reports of the species in natural habitat, and its impact, if any, on native fauna there is unknown.
26-11-2015 BOTANICAL GARDENS, SINGAPORE - PINK WATER LILY (Nymphaea rubra)

31-10-2016 XIAN, CHINA - AZURE WINGED MAGPIE (Cyanopica cyanus)
The azure-winged magpie (Cyanopica cyanus ) is a bird in the crow family. It is 31–35 cm long and similar in overall shape to the Eurasian magpie (Pica pica ) but is more slender with proportionately smaller legs and bill. It belongs to the genus Cyanopica.
It has a glossy black top to the head and a white throat. The underparts and the back are a light grey-fawn in colour with the wings and the feathers of the long (16–20 cm) tail an azure blue. It inhabits various types of coniferous (mainly pine) and broadleaf forest, including parks and gardens in the eastern populations.
It occurs over a large region of eastern Asia in China, Korea, Japan, and north into Mongolia and southern Siberia. The Iberian magpie from southwestern and central parts of the Iberian Peninsula, in Spain and Portugal was formerly thought to be conspecific, but recent genetic analysis has shown them to be distinct at species level.
Often azure-winged magpies find food as a family group or several groups making flocks of up to 70 birds. The largest groups congregate after the breeding season and throughout the winter months. Their diet consists mainly of acorns (oak seeds) and pine nuts, extensively supplemented by invertebrates and their larvae, soft fruits and berries, and also human-provided scraps in parks and towns.
This species usually nests in loose, open colonies with a single nest in each tree. There are usually 6–8 eggs that are incubated for 15 days. Azure-winged magpies that have asynchronous broods, creating a size hierarchy among nestlings, produce more eggs and fledge more nestlings than those which have synchronous broods.
The voice is a quick fired and metallic sounding kwink-kwink-kwink usually preceded by a single krarrah.
