3-12-2015 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.
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.
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.

3-12-2015 JURONG, SINGAPORE - SAFFRON FINCH (Sicalis flaveola)
%2010.jpg)
The saffron finch (Sicalis flaveola) is a tanager from South America that is common in open and semi-open areas in lowlands outside the Amazon Basin. They have a wide distribution in Colombia, northern Venezuela (where it is called "canario de tejado" or "roof canary"), western Ecuador, western Peru, eastern and southern Brazil (where it is called "canário-da-terra" or "native canary"), Bolivia, Paraguay, Uruguay, northern Argentina, and Trinidad and Tobago. It has also been introduced to Hawaii, Panama, Puerto Rico and elsewhere. Although commonly regarded as a canary, it is not related to the Atlantic canary. Formerly, it was placed in the Emberizidae but it is close to the seedeaters.
%2011.jpg)
The saffron finch was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the 12th edition of his Systema Naturae under the binomial name Fringilla flaveola. The specific epithet is a diminutive of the Latin flavus meaning "golden" or "yellow". The type locality is Suriname. The saffron finch is now placed in the genus Sicalis that was introduced in 1828 by the German zoologist Friedrich Boie.
The male is bright yellow with an orange crown which distinguishes it from most other yellow finches (the exception being the orange-fronted yellow finch). The females are more difficult to identify and are usually just a slightly duller version of the male, but in the southern subspecies S. f. pelzelni they are olive-brown with heavy dark streaks.
%2012.jpg)
Typically nesting in cavities, the saffron finch makes use of sites such as abandoned rufous hornero (Furnarius rufus) nests, bamboo branches and under house roofs - this species is tolerant of human proximity, appearing at suburban areas and frequenting bird tables. They have a pleasant but repetitious song which, combined with their appearance, has led to them being kept as caged birds in many areas. Males are polygamous, mating with two females during the nesting season, and territorial, which has led to the species being used for blood sporting with two males put in a cage in order to fight.
3-12-2015 JURONG, SINGAPORE - SCARLET IBIS (Eudocimus ruber)
%2021.jpg)
The scarlet ibis, sometimes called red ibis, (Eudocimus ruber) is a species of ibis in the bird family Threskiornithidae. It inhabits tropical South America and part of the Caribbean. In form, it resembles most of the other twenty-seven extant species of ibis, but its remarkably brilliant scarlet coloration makes it unmistakable. It is one of the two national birds of Trinidad and Tobago, and its Tupi–Guarani name, guará, is part of the name of several municipalities along the coast of Brazil.
This medium-sized wader is a hardy, numerous, and prolific bird, and it has protected status around the world. Its IUCN status is Least Concern. The legitimacy of Eudocimus ruber as a biological classification, however, is in dispute. Traditional Linnaean taxonomy classifies it as a unique species, but some scientists have moved to reclassify it as a subspecies of a more general American ibis species, along with its close relative, the American white ibis (Eudocimus albus).
3-12-2015 SINGAPORE - LONG TAILED MOCKINGBIRD (Mimus longicaudatus)
%2011.jpg)
The long-tailed mockingbird (Mimus longicaudatus) is a species of bird in the family Mimidae. It is found in Ecuador and Peru.
The long-tailed mockingbird has four subspecies, the nominate Mimus longicaudatus longicaudatus, M. l. platensis, M. l. albogriseus, and M. l. maranonicus.
The long-tailed mockingbird is 27 to 29.5 cm (10.6 to 11.6 in) long and weighs 54 to 79 g (1.9 to 2.8 oz) with an average of 66.6 g (2.35 oz). Males are slightly larger than females. Adults of the nominate subspecies have a broad white supercilium and a black stripe through the eye that touches a black patch on the white cheek. Their crown and upperparts are brownish gray with darker streaks. The wings and long tail are mostly dusky brown, with patches of white that show conspicuously in flight. The throat, belly, and vent area are white and the breast and flanks buff to dull brown. Juveniles are similar to adults with the addition of streaks on the chest.
M. l. albogriseus is smaller and grayer than the nominate, and the white on its tail tips is more extensive. M. l. platensis is similar to albogriseus but closer to the nominate in size and has a longer bill. M. l. maranonicus is very similar to the nominate and may not truly be a separate subspecies from it.
%2012.jpg)
The long-tailed mockingbird is found mostly along the Pacific coasts of Ecuador and Peru. The nominate M. l. longicaudatus inhabits most of the length of western Peru. M. l. albogriseus is in southwestern Ecuador, from central Manabí Province to Peru. M. l. platensis is found only on Isla de la Plata, about 30 km (19 mi) off the coast of Manabi. M. l. maranonicus is the anomaly; it is found inland along the upper Río Marañón in northwestern Peru.
The long-tailed mockingbird inhabits coastal desert scrub, arid woodland, and hedgerows and tree groves in agricultural areas. It is also found in gardens and parks. The coastal subspecies range from sea level to 1,900 m (6,200 ft), while M. l. maranonicus is found as high as 2,450 m (8,040 ft).
The long-tailed mockingbird primarily forages on the ground and hops and glides between feeding sites. It is omnivorous, feeding on invertebrates (both terrestrial and marine), fruits, and berries. It occurs in loose groups in the non-breeding season.

3-12-2015 JURONG, SINGAPORE - SUN CONURE (Aratinga solstitialis)
While their colors are somewhat similar to the equally popular Jenday Conure when they are juveniles, Sun Conures are widely regarded as the most colorful of all the Conure species. This is because a mature Sun Conure sports plumage in a variety of shades of red, yellow, green, orange, blue, and in some birds, tones of violet.
Another distinctive feature of the Sun Conure is the bare white patches of skin around the eyes, known as "eye rings." These patches are similar to the bare patches commonly noted in Macaw species and are seen by many as an attractive feature for a parrot to have.
3-12-2015 JURONG, SINGAPORE - WOOD DUCK (MALE) (Aix sponsa)
The Wood duck (Aix sponsa) is a species of perching duck from North America. The drake of this species is known to be one of the most colorful North American waterfowl. In 1918 the Wood duck was near extinction as a result of habitat loss and hunting. Wildlife management has fortunately protected this species so that it is amongst the most common ducks today in the eastern US.
The Wood duck is among the most stunningly beautiful of all water birds. Males are iridescent green and chestnut, with ornate patterns on almost every feather, while the elegant female has a delicate white pattern around her eye and a distinctive profile. These birds inhabit wooded swamps, where their nests are in holes up in trees or in the nest boxes around lake margins. These are one of a few duck species that have strong claws to perch on branches and grip bark.
Wood ducks are widespread across North America. Larger population breeds in Manitoba east to Nova Scotia, also south to Florida, Texas, the Gulf of Mexico, and Cuba. There is also a small Pacific coast population that breeds from British Columbia in Canada to California in the United States. These birds are year-round residents in parts of their southern range, but the northern populations migrate south for the winter. They overwinter in the southern United States near the Atlantic Coast. Wood ducks inhabit wooded areas on the banks of lakes, freshwater ponds, quiet rivers, wooded swamps, marshes, and creeks.
Wood ducks are diurnal birds and sleep on the water, except for females with ducklings. They feed by walking on land or dabbling, meaning they search for food from the surface of the water. They are social and often gather in flocks in the evening. They also migrate in small flocks or pairs. Although not territorial, Wood ducks will protect their mates by chasing, pecking, and hitting. Such battles are often short. When threatening another bird, they will jerk and jab with their beaks. Males are assumed to be dominant over females, and adults over young birds. Adults have 12 calls and ducklings have 5. Most calls made by adults are warning calls or to attract mates. Males and females both have pre-flight calls, and females have calls for locating their mate and calling their ducklings. Ducklings can make calls at 2 to 3 days old, have an alarm, threatening, and contact calls.
4-12-2015 JURONG, SINGAPORE - SAFFRON FINCH (MALE) (Sicalis flaveola)
The male is bright yellow with an orange crown which distinguishes it from most other yellow finches (the exception being the orange-fronted yellow finch).

4-12-2015 JURONG, SINGAPORE - SUN CONURE (Aratinga solstitialis)
The sun conure (Aratinga solstitialis), also known as the sun parakeet, is a medium-sized, vibrantly colored parrot native to northeastern South America. The adult male and female are similar in appearance, with black beaks, predominantly golden-yellow plumage, orange-flushed underparts and face, and green and blue-tipped wings and tails. Sun conures are very social birds, typically living in flocks. They form monogamous pairs for reproduction, and nest in palm cavities in the tropics. Sun conures mainly feed on fruits, flowers, berries, blossoms, seeds, nuts, and insects. Conures are commonly bred and kept in aviculture and may live up to 30 years. This species is currently threatened by loss of habitat and trapping for plumage or the pet trade. Sun conures are now listed as endangered by the International Union for Conservation of Nature.
The Sun parakeet (Aratinga solstitialis) is a medium-sized, brightly colored parrot native to northeastern South America. Sun parakeets are very social birds, typically living in flocks. They form monogamous pairs for reproduction and nest in palm cavities in the tropics. They are commonly bred and kept in aviculture and may live up to 30 years.
Adult Sun parakeets have a rich yellow crown, nape, mantle, lesser wing coverts, tips of the greater wing coverts, chest, and underwing coverts. The face and belly are orange with red around the ears. The base of the greater wing coverts, tertials, and base of the primaries are green, while the secondaries, tips of the primaries, and most of the primary coverts are dark blue. The tail is olive green with a blue tip. From below, all the flight feathers are dark greyish. The bill is black. The legs and the bare eye-ring are grey, but the latter often fade to white in captivity (so using the amount of grey or white in the eye ring for determining the "purity" of an individual can be misleading). The sexes are similar in plumage, although females may be lighter and slenderer in body, having a shorter tail, with a smaller, rounder head and a smaller beak. Juvenile Sun parakeets have predominantly green plumage. The distinctive yellow, orange, and reddish coloration on the back, abdomen, and head is attained with maturity.
Sun parakeets live in a relatively small region of northeastern South America: the north Brazilian state of Roraima, southern Guyana, extreme southern Suriname, and southern French Guiana. They also occur as vagrants to coastal French Guiana. These birds are mostly found in tropical habitats, but their exact ecological requirements remain relatively poorly known. They occur within dry savanna woodlands and coastal forests, but, at the edge of humid forests growing in foothills in the Guiana Shield, and cross more open savannah habitats only when traveling between patches of forest. Sun parakeets have been seen in shrublands along the Amazon riverbank, as well as forested valleys and coastal, seasonally flooded forests. They usually inhabit fruiting trees and palm groves.

3-12-2015 SINGAPORE - YELLOW HOODED BLACKBIRD (MALE) (Chrysomus icterocephalus)
%20(Chrysomus%20icterocephalus)%2020.jpg)
The yellow-hooded blackbird (Chrysomus icterocephalus) is a species of bird in the family Icteridae. It is found in grassy and brush areas near water in northern South America, and is generally fairly common. It is sexually dimorphic, and the genders resemble the respective genders of the larger yellow-headed blackbird of North America, though the male yellow-hooded blackbird lacks white in the wings.
In 2007, one was found in the Darien Lowlands of Panama. This was a rare vagrant, most likely from Colombia.
With a golden head, a white patch on black wings, and a call that sounds like a rusty farm gate opening, the Yellow-headed Blackbird demands your attention. Look for them in western and prairie wetlands, where they nest in reeds directly over the water. They’re just as impressive in winter, when huge flocks seem to roll across farm fields. Each bird gleans seeds from the ground, then leapfrogs over its flock mates to the front edge of the ever-advancing troupe.
%20(Chrysomus%20icterocephalus)%2021.jpg)
The Yellow-headed Blackbird often nests in the same marsh as the Red-winged Blackbird. The larger Yellow-headed Blackbird is dominant to the Red-winged Blackbird, and displaces the smaller blackbird from the prime nesting spots. The Yellow-headed Blackbird is strongly aggressive toward Marsh Wrens too, probably because of the egg-destroying habits of the wrens. When the Yellow-headed Blackbird finishes breeding and leaves the marsh, Marsh Wrens expand into former blackbird territories.
The male Yellow-headed Blackbird defends a small territory of prime nesting reeds. He may attract up to eight females to nest within his area. The male helps feed nestlings, but usually only in the first nest established in his territory. The other females have to feed their young all by themselves.
In 1825, Charles Lucien Bonaparte, nephew of Napoleon Bonaparte, gave the first detailed description of the Yellow-headed Blackbird, which was collected in 1820 by Thomas Say and Sir John Richardson.
Because Yellow-headed Blackbirds always build their nests over the water, nestlings sometimes fall in and have to swim short distances to vegetation.
Pleistocene fossils of Yellow-headed Blackbirds (from 100,000 years ago) have been dug up in California, New Mexico, and Utah.
The Yellow-headed Blackbird’s scientific name, Xanthocephalus, means “yellow head.”
The oldest Yellow-headed Blackbird on record was at least 11 years, 8 months old. It was banded in Saskatchewan in 1983 and was found in Nebraska in 1995.
3-12-2015 JURONG, SINGAPORE - AUSTRALIAN PELICAN (Pelecanus conspicillatus)
The Australian pelican (Pelecanus conspicillatus) is a large waterbird in the family Pelecanidae, widespread on the inland and coastal waters of Australia and New Guinea, also in Fiji, parts of Indonesia and as a vagrant in New Zealand. It is a predominantly white bird with black wings and a pink bill. It has been recorded as having the longest bill of any living bird. It mainly eats fish, but will also consume birds and scavenge for scraps if the opportunity arises.
The Australian pelican was first described by Dutch naturalist Coenraad Jacob Temminck in 1824. Its specific epithet is derived from the Latin verb conspicere, meaning 'to behold', and refers to the 'spectacled' appearance created by its conspicuous eye markings.
The Australian pelican is medium-sized by pelican standards, with a wingspan of 2.3 to 2.6 m (7.5 to 8.5 ft). Weight can range from 4 to 13 kg (8.8 to 28.7 lb), although most of these pelicans weigh between 4.54 and 7.7 kg (10.0 and 17.0 lb). The average weight of four unsexed Australian pelicans was 5.5 kg (12 lb), making this the second heaviest Australian flying bird species on average, after the brolga, although the male of the more sexually dimorphic Australian bustard weighs a bit more at average and maximum weights (both birds are, of course, much smaller than the cassowary and emu). The pale, pinkish bill is enormous, even by pelican standards, and is the largest bill in the avian world. The record-sized bill was 50 cm (20 in) long. Females are slightly smaller with a notably smaller bill, which can measure as small as 34.6 cm (13.6 in) at maturity. The total length is boosted by the bill to 152–188 cm (60–74 in), which makes it rank alongside the Dalmatian pelican as the longest of pelicans.
Overall, the Australian pelican is predominantly white in colour. There is a white panel on the upper-wing and a white-V on the rump set against black along the primaries. During courtship, the orbital skin and distal quarter of the bill are orange-coloured with the pouch variously turning dark blue, pink and scarlet. The non-breeding adult has its bill and eye-ring a pale yellow and the pouch is a pale pinkish. Juvenile birds are similar to the adults, but with black replaced with brown and the white patch on upper wing reduced. Overall, their appearance is somewhat similar to several other pelicans, though the species is allopatric.
This species can occur in large expanses of mainland Australia and Tasmania. Australian pelicans occur primarily in large expanses of open water without dense aquatic vegetation. The habitats that can support them include large lakes, reservoirs, billabongs and rivers, as well as estuaries, swamps, temporarily flooded areas in arid zones, drainage channels in farmland, salt evaporation ponds and coastal lagoons. The surrounding environment is unimportant: it can be forest, grassland, desert, estuarine mudflats, an ornamental city park, or industrial wasteland, provided only that there is open water able to support a sufficient supply of food. However, they do seem to prefer areas where disturbance is relatively low while breeding. They may also roost on mudflats, sandbars, beaches, reefs, jetties and pilings.
The species became first known to occur in New Zealand from a specimen shot at Jerusalem in 1890 and small numbers of subfossil bones, the first found at Lake Grassmere in 1947, followed by records of other stray individuals. The bones were later described as a new (sub)species, Pelecanus (conspicillatus) novaezealandiae (Scarlett, 1966: "New Zealand pelican") as they appeared to be larger, but Worthy (1998), reviewing new material, determined that they were not separable from the Australian population. These fossils were first found in 1930.
Australian pelicans follow no particular schedule of regular movement, simply following the availability of food supplies. Drought frequently precedes movements. When the normally barren Lake Eyre filled during 1974 to 1976, for example, only a handful of pelicans remained around the coastal cities: when the great inland lakes dried again, the population dispersed once more, flocks of thousands being seen on the northern coasts. On some occasions, they are simply blown by the wind to new locations. It is a fairly regular visitor to the southern coast of New Guinea, as well as the Bismarck Islands and Solomon Islands. It occurs as a vagrant to Christmas Island, Vanuatu, Fiji, Palau and New Zealand. A population irruption occurred in 1978 into Indonesia, with Australian pelicans reaching Sulawesi, Java and possibly also Sumatra.
%2010.jpg)
Australian pelicans feed by plunge-diving while swimming on the surface of the water. They work in groups to drive fish to shallower water, where they stick their sensitive bills in to snatch their prey. Some feeding grounds in large bodies of water have included up to 1,900 individual birds. They will sometimes also forage solitarily. Their predominant prey is fish and they commonly feed on introduced species such as goldfish, European carp and European perch. When possible, they also eat native fish, with a seeming preference for the perch Leiopotherapon unicolor. However, the Australian pelican seems to be less of a piscivore and more catholic in taste than other pelicans. It regularly feeds on insects and many aquatic crustaceans, especially the common yabby, prawns and the shrimps in the genus Macrobrachium. This pelican also takes other birds with some frequency, such as silver gulls, Australian white ibis and grey teal, including eggs, nestlings, fledglings and adults, which they may kill by pinning them underwater and drowning them. Reptiles, amphibians and small mammals are also taken when available. Reportedly even small dogs have been swallowed. The Australian pelican is an occasional kleptoparasite of other water birds, such as cormorants. Cannibalism of young pelicans has also been reported.
