20-12-2015 JURONG, SINGAPORE - MASKED LAPWING (Vanellus miles)


The Masked lapwing (Vanellus miles ) is a large, common, and conspicuous bird. It spends most of its time on the ground and has several distinctive calls. It is common in Australian fields and open land, and is known for its defensive swooping behavior during the nesting season. The species is also known as the Masked plover and often called the Spur-winged plover or just plover in its native range.

The Masked lapwing is the largest representative of the family Charadriidae. It has a conspicuous yellow spur on the carpal joint of each wing. The subspecies from northern Australia and New Guinea (V. m. miles ) have an all-white neck and large yellow wattles with the male having a distinctive mask and larger wattles. The subspecies found in the southern and eastern states of Australia and in New Zealand (V. m. novaehollandiae ), and often locally called the Spur-winged plover, has a black neck-stripe and smaller wattles. (Note that the northern hemisphere Spur-winged plover is a different bird.)

Masked lapwings are native to the northern and eastern parts of Australia, New Zealand, and New Guinea. These birds don’t migrate and prefer to live on the edges of wetlands, and in other moist, open environments. However, they are adaptable and can often be found in surprisingly arid areas, pasturelands, and urban areas.

14-9-2015 CIUDAD DE ENCANTADA, CUENCA - EURASIAN NUTHATCH (Sitta europaea)


The Eurasian nuthatch or wood nuthatch (Sitta europaea) is a small passerine bird found throughout the Palearctic and in Europe. Like other nuthatches, it is a short-tailed bird with a long bill, blue-gray upperparts and a black eye-stripe. It is a vocal bird with a repeated loud dwip call. There are more than 20 subspecies in three main groups; birds in the west of the range have orange-buff underparts and a white throat, those in Russia have whitish underparts, and those in the east have a similar appearance to European birds, but lack the white throat.

Its preferred habitat is mature deciduous or mixed woodland with large, old trees, preferably oak. Pairs hold permanent territories, and nest in tree holes, usually old woodpecker nests, but sometimes natural cavities. If the entrance to the hole is too large, the female plasters it with mud to reduce its size, and often coats the inside of the cavity too. The six to nine red-speckled white eggs are laid on a deep base of pine or other wood chips.

The Eurasian nuthatch eats mainly insects , particularly caterpillars and beetles, although in autumn and winter its diet is supplemented with nuts and seeds. The young are fed mainly on insects, with some seeds, food items mainly being found on tree trunks and large branches. The nuthatch can forage when descending trees head first, as well as when climbing. It readily visits bird tables, eating fatty man-made food items as well as seeds. It is an inveterate hoarder, storing food year-round. Its main natural predator is the Eurasian sparrowhawk.


The Eurasian nuthatch's breeding range extends across temperate Eurasia from Great Britain (but not Ireland) to Japan. It is found between the 16–20 °C (61–68 °F) July isotherms, north to about latitude 64°N in western Russia and 69°N in Siberia. It breeds south to the Mediterranean in Europe, although it is absent from the islands, other than Sicily, and in most of Russia the southern boundary is around 54–55°N. In the east, the range includes most of China and Taiwan and much of Korea. It has occurred as a vagrant in Lebanon and the Channel Islands, and the nominate race has been recorded a few times in Finland where S. e. asiatica is the normal form.


Most populations are sedentary, apart from some post-breeding dispersal of young birds, and there is a reluctance to cross even short stretches of open water. Northern and eastern breeders are dependent on the cones of the Siberian stone pine, and if the crop fails many birds of the S. e. asiatica subspecies may move west into northern Sweden and Finland in autumn, sometimes staying to breed. Siberian S. e. arctica may make more limited movements south and east in winter, and S. e. amurensis, from southeast Russia, is regular in winter in Korea.


The preferred habitat is mature woodland with large, old trees, which provide extensive growth for foraging and nesting holes. In Europe, deciduous or mixed forest is favoured, particularly when containing oak. Parks, old orchards and other wooded habitats may be occupied as long as they have at least a 1 ha (2.5 acres) block of suitable trees. Particularly in mountains, old spruce and pine forests are used, and pine is also favoured in Taiwan. In most of Russia, conifers are used for nesting, but population densities are relatively low. Moroccan birds nest in oak, Atlas cedar and fir. Unusual habitats include dwarf juniper in Mongolia and rocky terrain in a limited part of southern Siberia.


The Eurasian nuthatch is primarily a lowland bird in the north of its range, but reaches the tree-line in Switzerland, at 1,200 m (3,900 ft) or higher, and breeds occasionally at 1,800–2,100 m (5,900–6,900 ft) in Austria. It breeds at similar levels in the mountains of Turkey, the Middle East and Central Asia. It is mainly a mountain bird in southern Japan, 760–2,100 m (2,490–6,890 ft), and Taiwan, 800–3,300 m (2,600–10,800 ft), but in southern China, the chestnut-vented nuthatch is the highland species, with the Eurasian species at lower levels.


Nuthatches are monogamous, and a pair occupies a breeding territory in which it spends the winter as well. Territory sizes range from 2–10 ha (5–25 acres) in Europe to an average of 30.2 ha (75 acres) in the sub-optimal conifer forests of Siberia. The male sings to defend his territory and attract a mate. Both sexes have a courtship display with a floating, quivering flight, and the male will also make circular flights with a spread tail and raised head. He will also feed the female while courting her. Despite the lifelong pairing, genetic research in Germany showed that at least 10% of the young in the study area were fathered by another male, usually from an adjacent territory.


11-12-2015 BAGAN, MYANMAR - BROWN SHRIKE (Lanius cristatus)


The brown shrike (Lanius cristatus) is a bird in the shrike family that is found mainly in Asia. It is closely related to the red-backed shrike (L. collurio) and isabelline shrike (L. isabellinus). The genus name, Lanius, is derived from the Latin word for "butcher", and some shrikes are also known as "butcher birds" because of their feeding habits. The specific cristatus is Latin for "crested", used in a broader sense than in English. The common English name "shrike" is from Old English scríc, "shriek", referring to the shrill call.

Like most other shrikes, it has a distinctive black "bandit-mask" through the eye and is found mainly in open scrub habitats, where it perches on the tops of thorny bushes in search of prey. Several populations of this widespread species form distinctive subspecies which breed in temperate Asia and migrate to their winter quarters in tropical Asia. They are sometimes found as vagrants in Europe and North America.


This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch. The use of multiple measurements allows discrimination of the sex of about 90% of the birds. Subspecies lucionensis has a grey crown shading into the brown upperparts and the rump appears more rufous than the rest of the upper back. The tail is more brownish and not as reddish as in the red-backed shrike. Younger birds of lucionensis have a brown crown and lack the grey on the head. Subspecies superciliosus has a broad white supercilium and a richer reddish crown. The tail is redder and tipped in white.

A number of confusing forms are known from central Asia where the populations of cristatus, isabellinus and collurio overlap. The taxonomy has been in a state of flux and some forms such as phoenicuroides formerly considered as subspecies of L. cristatus have been moved to the species L. isabellinus. Subspecies lucionensis has been recorded interbreeding with superciliosus in Ishikawa, Japan while superciliosus has interbred with Lanius tigrinus in central Japan.


The nominate form breeds in northern Asia from Mongolia to Siberia and winters in South Asia, Myanmar and the Malay Peninsula. The race confusus described from the same region is not well marked but is said to have a wider white brow and paler upperparts and is sometimes included within the nominate population. Subspecies superciliosus (sometimes called the Japanese shrike) breeds on the islands of Sakhalin, Kuril and Japan and winters in Hainan, Sumatra, Java, and the Sundas. Subspecies lucionensis, sometimes known as the Philippine shrike (local names: tarat or pakis-kis), breeds in Korea and eastern China wintering mainly in Taiwan and the Philippines but also on the Andaman Islands and in peninsular India. Stuart Baker suggested that the species may breed in the Cachar Hills of Assam but the idea was questioned by Claud Buchanan Ticehurst.

This species is rare in Europe and vagrants have been recorded in the United States and Canada.


The brown shrike is a migratory species and ringing studies show that they have high fidelity to their wintering sites, often returning to the same locations each winter. They begin establishing wintering territories shortly after arrival and their loud chattering or rattling calls are distinctive. Birds that arrive early and establish territories appear to have an advantage over those that arrive later in the winter areas. The timing of their migration is very regular with their arrival in winter to India in August and September and departure in April. During their winter period, they go through a premigratory moult. Their song in the winter quarters is faint and somewhat resembles the call of the rosy starling and often includes mimicry of other birds. The beak remains closed when singing and only throat pulsations are visible although the bird moves its tail up and down while singing.

The breeding season is late May or June and the breeding habitat includes the taiga, forest to semi-desert where they build a nest in a tree or bush, laying two to six eggs.

They feed mainly on insects, especially Lepidoptera. Like other shrikes, they impale prey on thorns. Small birds and lizards are also sometimes preyed upon. A white-eye (Zosterops) has been recorded in its larder. They typically look out for prey from a perch and fly down towards the ground to capture them.

8-12-2015 KUALA LUMPUR, MALAYSIA - AUSTRALIAN KING PARROT (Alisterus scapularis)


The Australian king parrot (Alisterus scapularis) is a species of parrot endemic to eastern Australia ranging from Cooktown in Queensland to Port Campbell in Victoria. Found in humid and heavily forested upland regions of the eastern portion of the continent, including eucalyptus wooded areas in and directly adjacent to subtropical and temperate rainforest. They feed on fruits and seeds gathered from trees or on the ground.

The Australian king parrot was first described by the German naturalist Martin Lichtenstein in 1816 as Psittacus scapularis. The species belongs to the genus Alisterus, whose three members are also known as king parrots. The species are sometimes allied to the genus Aprosmictus.

Two subspecies are recognised, which are differentiated by size:

A. s. minor (Mathews, 1911)
A. s. scapularis (Lichtenstein, 1816)
Naturally-occurring hybrids with the red-winged parrot (Aprosmictus erythropterus) have been recorded from Bell in southeastern Queensland.

"Australian king parrot" has been designated the official name by the International Ornithologists' Union (IOC).


Adults of both sexes are about 43 cm (17 in) in length, including the long, broad tail. The adult male has a red head, breast, and lower undersides, with a blue band on the back of the neck between the red above and green on the back, the wings are green and each has a pale green shoulder band, the tail is green, and the rump is blue. The male has a reddish-orange upper mandible with a black tip, a black lower mandible with an orange base, and yellow irises. The plumage of the female is very different from the male having a green head and breast, a grey beak, and the pale shoulder band is small or absent. Juveniles of both sexes have brown irises and a yellowish beak, and otherwise resemble the female.

The two subspecies are A. s. minor, found at the northern limit of the species range and is similar in appearance to the nominate subspecies but smaller, typically about 5 cm (2 in) smaller in length.

On those rare individuals which have areas without melanin, feathers are orange to yellow. Such a bird can look startingly different from the more common scarlet and green variety.


Australian king parrots range from north and central Queensland to southern Victoria. They are frequently seen in small groups with various species of rosella. Further from their normal eastern upland habitat, they are also found in Canberra during winter, the outer western and northern suburbs of Sydney, and the Carnarvon Gorge in central Queensland.


In their native Australia, king parrots are occasionally bred in aviaries and kept as calm and relatively quiet household pets if hand-raised. As pets, they have limited "talking" ability and normally prefer not to be handled, but they do bond readily to people and can be very devoted.
They tend to be selective in their choice of seeds that they eat, preferring black sunflower seeds and tend not to ingest small seeds found in pre-packaged retail bags.

7-12-2015 KUALA LUMPUR, MALAYA - GREAT HORNBILL (Buceros bicornis)


Roost sites are used regularly and birds arrive punctually at sunset from long distances, following the same routes each day. Several tall trees in the vicinity may be used, the birds choosing the highest branches with little foliage. They jockey for position until late at dusk. When sleeping they draw their neck back and the bill is held upwards at an angle.

The great hornbill is threatened mainly by habitat loss due to deforestation. It is hunted for its meat, fat and body parts like casque and tail feathers, which are used as adornments. Tribal peoples hunt the great Indian hornbill for its various parts. The beaks and head are used in charms and the flesh is believed to be medicinal. Young birds are considered a delicacy. Declines in population have been noted in many areas such as Cambodia.

Tribesmen in parts of northeastern India use the feathers for head-dresses, and the skulls are often worn as decorations.  The Sema Nagas consider the flesh unfit for eating, believing that it produces sores on their feet, as in the bird. When dancing with the feathers of the hornbill, they avoid eating vegetables, as doing so is also believed to produce the same sores on the feet.

Very few hornbills are held in captivity, and few of them breed well. Females at the nests are extremely easy to capture, and birds caught in the wild are mostly female. Breeding them in captivity has been notoriously difficult, with fewer than a dozen successful attempts. Their extreme selectivity for mates and their long and strong pair bonds make them difficult to maintain for breeding.

Captive great hornbills eat fruits and meat, a healthy diet consisting mostly of fruit and some source of protein. A few have been tamed in captivity but their behaviour in captivity is described as highly strung. Captive specimens bask in the sun with outstretched wings.

8-12-2015 KUALA LUMPUR, MALAYSIA - BROWN WOOD OWL (Strix leptogrammica)


The brown wood owl (Strix leptogrammica) is found in India, Bangladesh, Sri Lanka, Indonesia, Taiwan, and south China. The brown wood owl is a resident breeder in south Asia. This species is a part of the family of owls known as typical owls (Strigidae), which contains most species of owl. It belongs to the earless owl genus Strix.

The brown wood owl is medium large (45–57 cm), with upperparts uniformly dark brown, with faint white spotting on the shoulders. The underparts are buff with brown streaking. The facial disc is brown or rufous, edged with white and without concentric barring, and the eyes are dark brown. There is a white neckband. The sexes are similar in appearance.


Their call is a (hoo) hoo hoo HOO, or a deep goke-goke-ga-LOOO, or a loud scream. Their alarm call is a bark, wow-wow. Some subspecies are known to produce distinct vocalizations; they are also different in appearance and parapatric, and might be distinct species: The northern Strix (leptogrammica) newarensis group (Himalayan wood-owl; present subspecies newarensis, ticehursti, laotiana and caligata) which occur from the Himalayan foothills of Kashmir east to Taiwan have a soft low to-hooh not unlike a rock dove cooing. S. (l.) bartelsi (Bartels's wood-owl), Javan wood-owl from Java, the southeasternmost taxon, has a loud, forceful, single HOOH! with long pauses between calls.

This species is highly nocturnal and is commonly found in dense forests. It can often be located by the small birds that mob it while it is roosting in a tree. The diet of the brown wood owl consists mainly of small mammals, birds, and reptiles.

8-12-2015 KUALA LUMPUR, MALAYSIA - BUFFY FISH OWL (Ketupa ketupu)


The buffy fish owl (Ketupa ketupu), also known as the Malay fish owl, is a fish owl in the family Strigidae. It is native to Southeast Asia and lives foremost in tropical forests and wetlands. Due to its wide distribution and assumed stable population, it is listed as Least Concern on the IUCN Red List since 2004.
The buffy fish owl is buff brown with darker tawny brown feathers on the back. Its face is paler and it has light brown eyebrows. With an adult size of 40 to 48 cm (16 to 19 in) and a weight of 1,028 to 2,100 g (2.3 to 4.6 lb), it is the smallest fish owl species.

Like all fish owls, the buffy fish owl has prominent ear tufts on the sides of the head. Its wing feathers and tail are broadly barred yellowish and dark brown. The wings are distinctly rounded in shape. The underparts are a yellowish brown, rich buff or fulvous with broad blackish shaft stripes. Its long legs are not feathered.

The fish owls have large, powerful, and curved talons and a longitudinal sharp keel underneath the middle claw with all having sharp cutting edges that are very much like those of eagle owls. Unlike fish-eating diurnal raptors, they do not submerge any part of their body while hunting, preferring only to put their feet into the water, although fish owls wade into the shallows. The feathers of fish owls are not soft to the touch and lack the comb and hair-like fringes to the primaries, which allow other owls to fly silently in order to ambush their prey. Due to the lack of these feather-specializations, fish owl wing beats make sounds. The lack of a deep facial disc in fish owls is another indication of the unimportance of sound relative to vision in these owls, as facial disc depth (as well as inner ear size) are directly related to how important sound is to an owl's hunting behavior. Also different from most any other kind of owl, the bill is placed on the face between the eyes rather than below it, which is said to impart this fish owl with a "remarkably morose and sinister expression". Similar adaptations, such as unwillingness to submerge beyond their legs and lack of sound-muffling feathers are also seen in the African fishing owls, which do not seem to be directly related. Due to their neat replacement of each other in range, at one time the tawny and buffy fish owls were considered the same species but there are a number of physical, anatomical, habitat, and behavioral distinctions between them.


The buffy fish owl is distributed from Bangladesh, Myanmar, Thailand, Malaysia and Singapore to Cambodia, Laos, Vietnam, and the Sunda Islands. On Cocos (Keeling) Island, it is non-breeding. It inhabits tropical forests and freshwater wetlands near rivers, lakes and aquaculture sites up to an elevation of 1,600 m (5,200 ft). It also lives in plantations, and rural and urban gardens.

A range of vocalizations has been attributed to the buffy fish owl. Among those recorded are included hissing sounds and a rattling kutook, repeated rapidly about seven times. Also recorded has been a ringing, loud pof-pof-pof and a high, hawk-like hie-e-e-e-e-keek series of notes. The buffy fish owl is rather noisy before breeding, and pairs may engage in bouts of duetting for several minutes at a time. During the daytime, it shelters often singly in densely foliaged trees.


The buffy fish owl feeds foremost on fish, crabs, frogs, small reptiles and birds. It also forages on carrion. Stomach content found in Javan buffy fish owls included insects, winged ants and winged termites, goldfish (Carassius auratus), gold-ringed cat snake (Boiga dendrophila), immature false gharials (Tomistoma schlegelii), red junglefowl (Gallus gallus), black rat (Rattus rattus), and fruit bats.

It has been recorded consuming remains of a crocodile and a Sunda stink badger (Mydaus javanensis). The buffy fish owl does not produce firm pellets as do most owls. Instead, bones, and frog and insect remains are ejected in pieces and fall to the ground below the roost. Prey remains have only been found within the nest, never around or below the nest as is commonly recorded in other owls. The buffy fish owl hunts mainly from the bank, swooping down much in the manner of a fish eagle but never getting its feathers wet. It also walks into shallow streams and brooks, additionally snatching food in such locations.


Eggs of buffy fish owls have mainly been found in February through April in western Java, less commonly into May, and in the Malay Peninsula also in September through January. The buffy fish owl frequently nests on top of a large fern (Asplenium nidus), but nests have also been recorded in the fork of a tall bough covered in ferns and moss, on orchid beds and in tree holes. More rarely, rocky sites have been used as nesting sites, even behind waterfalls. The nest is usually merely a scrape into the surface of a fern with no structure or lining, as owls do not build nests. Abandoned bird nests built by other species have been used, including those of brahminy kite (Haliastur indus). Only one egg per breeding season has ever been recorded in a buffy fish owl nest, giving them the smallest clutch size of any owl alongside the spot-bellied eagle owl (B. nipalensis) and the barred eagle owl (B. sumatranus), which also have only ever been recorded with a single-egg clutch. The egg is round, oval and dull white. The average dimensions of eggs in western Java was 57.4 mm × 47 mm (2.26 in × 1.85 in). Incubation of the eggs lasts 28 to 29 days and fledging occurs after six weeks. This species is generally faring well for a large raptorial bird and has been inadvertently aided by commercial fisheries and ornamental ponds, which they visit by night to hunt. Sometimes, they incur persecution from owners of such ponds for taking stock.

8-12-2015 KUALA LUMPUR, MALAYSIA - BRAHMINY KITE EAGLE (Haliastur indus)


The brahminy kite (Haliastur indus), also known as the red-backed sea-eagle in Australia, is a medium-sized bird of prey in the family Accipitridae, which also includes many other diurnal raptors, such as eagles, buzzards, and harriers. They are found in the Indian subcontinent, Southeast Asia, and Australia. They are found mainly on the coast and in inland wetlands, where they feed on dead fish and other prey. Adults have a reddish-brown body plumage contrasting with their white head and breast which make them easy to distinguish from other birds of prey.


Young birds may indulge in play behaviour, dropping leaves and attempting to catch them in the air. When fishing over water, they may sometimes land in the water, but manage to swim and take off without much trouble.

They roost communally on large and isolated trees and as many as 600 have been seen at one location.

They may mob larger raptors such as the Aquila eagles. In some incidents where brahminy kites mobbed steppe eagles (Aquila rapax), they were attacked and injured or killed.

A number of ectoparasitic bird lice in the genera Kurodaia, Colpocephalum, and Degeeriella have been reported.

8-12-2015 KUALA LUMPUR - INDIAN BLUE PEAFOWL (Pavo cristatus)


Peacocks are polygamous, and the breeding season is spread out but appears to be dependent on the rains. Peafowls usually reach sexual maturity at the age of 2 to 3 years old. Several males may congregate at a lek site and these males are often closely related. Males at leks appear to maintain small territories next to each other and they allow females to visit them and make no attempt to guard harems. Females do not appear to favour specific males. The males display in courtship by raising the upper-tail coverts into an arched fan. The wings are held half open and drooped and it periodically vibrates the long feathers, producing a ruffling sound. The cock faces the hen initially and struts and prances around and sometimes turns around to display the tail. Males may also freeze over food to invite a female in a form of courtship feeding. Males may display even in the absence of females. When a male is displaying, females do not appear to show any interest and usually continue their foraging.

The peak season in southern India is April to May, January to March in Sri Lanka and June in northern India. The nest is a shallow scrape in the ground lined with leaves, sticks and other debris. Nests are sometimes placed on buildings and, in earlier times, have been recorded using the disused nest platforms of the white-rumped vultures. The clutch consists of 4–8 fawn to buff white eggs which are incubated only by the female. The eggs take about 28 days to hatch. The chicks are nidifugous and follow the mother around after hatching. Downy young may sometimes climb on their mothers' back and the female may carry them in flight to a safe tree branch. An unusual instance of a male incubating a clutch of eggs has been reported.


Peafowl are omnivorous and eat seeds, insects (including termites), worms, fruits, small mammals, frogs, and reptiles (such as lizards). They feed on small snakes but keep their distance from larger ones. In the Gir forest of Gujarat, a large percentage of their food is made up of the fallen berries of Zizyphus. They also feed on tree and flower buds, petals, grain, and grass and bamboo shoots. Around cultivated areas, peafowl feed on a wide range of crops such as groundnut, tomato, paddy, chili and even bananas. Around human habitations, they feed on a variety of food scraps and even human excreta. In the countryside, it is particularly partial to crops and garden plants.

Large animals such as leopards, dholes, golden jackals, and tigers can ambush adult peafowls. However, only leopards regularly prey upon peafowls as adult peafowls are difficult to catch since they can usually escape ground predators by flying into trees. They are also sometimes hunted by large birds of prey such as the changeable hawk-eagle and rock eagle-owl. Chicks are somewhat more prone to predation than adult birds. Adults living near human habitations are sometimes hunted by domestic dogs or by humans in some areas (southern Tamil Nadu) for folk remedies involving the use of "peacock oil".

Foraging in groups provides some safety as there are more eyes to look out for predators. They also roost on high tree tops to avoid terrestrial predators, especially leopards.

In captivity, birds have been known to live for 23 years but it is estimated that they live for only about 15 years in the wild.

8-12-2015 KUALA LUMPUR, MALAYSIA - YELLOW BILLED STORK (JUVENILE) (Mycteria ibis)


Breeding is seasonal and appears to be stimulated by the peak of long heavy rainfall and resultant flooding of shallow marshes, usually near Lake Victoria. This flooding is linked to an increase in prey fish availability; and reproduction is therefore synchronised with this peak in food availability. In such observations near Kisumu, M.P. Kahl's explanation for this trend was that in the dry season, most prey fish are forced to leave the dried-up, deoxygenated marshes that cannot support them and retreat to the deep waters of Lake Victoria where the storks cannot reach them. However, fish move back up the streams on the onset of rain and spread out over the marshes to breed, where they become accessible to the storks. By nesting at this time and providing that the rains do not end pre-maturely, the storks are guaranteed a plentiful food supply for their young.

The yellow-billed stork may also begin nesting and breeding at the end of long rains. This occurs especially on flat extensive marshlands as water levels gradually decrease and concentrate fish sufficiently for the storks to feed on. However, unseasonal rainfall has also been reported to induce off-season breeding in northern Botswana and western and eastern Kenya. Rainfall may cause local flooding and hence ideal feeding conditions. This stork appears to breed simply when rainfall and local flooding are optimal and hence seems to be flexible in its temporal breeding pattern, which varies with rainfall pattern throughout the African continent.


As with all stork species, male yellow-billed storks select and occupy potential nest sites in trees, whereupon females attempt to approach the males. The yellow-billed stork has an extensive repertoire of courtship behaviours near and at the nest that may lead to pair formation and copulation. Generally, these courtship behaviours are also assumed to be common to all Mycteria species and show remarkable homology within the genus Mycteria. After the male has initially established at the nesting-site and the female begins to approach, he displays behaviours that advertise himself to her. One of these is the Display Preening, whereby the male pretends to strip down each of his extended wings with the bill several times each side and the bill does not effectively close around the feathers. Another observed display among males is the Swaying-Twig Grasping. Here, the male stands on the potential nesting-site and bends over to gently grasp and release underlying twigs at regular intervals. This is sometimes accompanied by side-to-side oscillations of the neck and head and he continues to pick at twigs in between such movements.

Reciprocally, approaching females display their own distinct behaviours. One such behaviour is the Balancing Posture, whereby she walks with a horizontal body axis and extended wings toward the male occupying the nesting-site. Later, when the female continues to approach or already stands near an established male, she may also engage in Gaping. Here, the bill is gaped open slightly with the neck inclined upward at about 45° and often occurs in conjunction with the Balancing Posture. This behaviour ordinarily continues if the male accepts the female and has allowed her to enter the nest, but the female usually closes her wings by this time. The male may also continue his Display Preening when standing next to the female in the nest.


During copulation, the male steps onto the female's back from the side, hooks his feet over her shoulders, holds out his wings for balance and finally bends his legs to lower himself for cloacal contact, as happens in most birds. In turn, the female holds out her wings almost horizontally. The process is accompanied by bill clattering from the male as he regularly opens and closes his mandibles and vigorously shakes his head to beat his bill against the female's. In turn, the female keeps her bill horizontal with the male's, or inclined downward at approximately 45 degrees. Average copulation time in this species has been calculated as 15.7 seconds.

The female typically lays 2-4 eggs on alternate days and average clutch size has been recorded as 2.5. The male and female share duties to incubate the eggs, which takes up to 30 days. As in many other stork species, hatching is asynchronous (usually at 1- to 2-day intervals), so that the young in the brood differ considerably in body size at any one time. During food shortage, the smaller young are at risk of being outcompeted for food by their larger nest-mates.

Both parents share duties of guarding and feeding the young until the latter are about 21 days old. Thereafter, both parents forage to attend to the young's intense food demands. Alongside parental feeding by regurgitation of fish, parents have also been observed to regurgitate water into the open bills of their nestlings, especially on hot days. This may aid the typical thermoregulatory strategy of the young (common to all stork species) to excrete dilute urine down their legs in response to hot weather. Water regurgitated over the young serves as a water supplement in addition to fluid in their food, so that they have sufficient water to continue urinating down their legs to avoid hyperventilation. Additionally, parents sometimes help keep the young cool by shading them with their open wings.

The nestlings usually fledge after 50–55 days of hatching and fly away from the nest. However, after leaving the nest for the first time, the offspring often return there to be fed by their parents and roost with them for another 1–3 weeks.It is also thought that individuals are not fully adult until 3 years old and despite lack of data, new adults are thought to not breed until much later than this.
Fledglings have also been observed to not differ considerably in their foraging and feeding strategies from adults. In one investigation, four adult, hand-reared yellow-billed storks kept in captivity showed typical grope-feeding and foot stirring shortly after they were introduced to bodies of water. Hence, this suggests that such feeding techniques in this species are innate.

8-12-2015 KUALA LUMPUR, MALAYSIA - AFRICAN SACRED IBIS (Threskiornis aethiopicus ssp. aethiopicus)


The African sacred ibis (Threskiornis aethiopicus) is a species of ibis, a wading bird of the family Threskiornithidae. It is native to much of Africa, as well as small parts of Iraq, Iran and Kuwait.[1] It is especially known for its role in Ancient Egyptian religion, where it was linked to the god Thoth. The species is currently extirpated from Egypt.


Wingspan is 112 to 124 cm (44 to 49 in) and body weight 1.35 to 1.5 kg (3.0 to 3.3 lb). Males are generally slightly larger than females.

The bald head and neck, thick curved bill and legs are black. The white wings show a black rear border in flight. The eyes are brown with a dark red orbital ring. Sexes are similar, but juveniles have dirty white plumage, a smaller bill and some feathering on the neck, greenish-brown scapulars and more black on the primary coverts.

This bird is usually silent, but occasionally makes puppy-like yelping noises, unlike its vocal relative, the hadada ibis.


The sacred ibis breeds in Sub-Saharan Africa and southeastern Iraq. A number of populations are migrant with the rains; some of the South African birds migrate 1,500 km as far north as Zambia, the African birds north of the equator migrate in the opposite direction. The Iraqi population usually migrates to southwestern Iran, but wandering vagrants have been seen as far south as Oman (rare, but regular) and as far north as the Caspian coasts of Kazakhstan and Russia (before 1945).

Africa
It was formerly found in North Africa including Egypt, where it was commonly venerated and mummified as a votive offering to the god Thoth. For many centuries until the Roman period the main temples buried a few dozen of thousands of birds a year, and to sustain sufficient numbers for the demand for sacrifices by pilgrims from all over Egypt, it was for some time believed that ibis breeding farms (called ibiotropheia by Herodotus) existed. Aristotle mentions in c. 350 BC that many sacred ibises are found all over Egypt. Strabo, writing around 20 AD, mentions large amounts of the birds in the streets of Alexandria, where he was living at the time; picking through the trash, attacking provisions, and defiling everything with their dung. Pierre Belon notes the many ibises in Egypt during his travels there in the late 1540s (he thought they were an odd type of stork). Benoît de Maillet, in his Description de l'Egypte (1735) relates that at the turn of the 17th century, when the great caravans travelled yearly to Mecca, great clouds of ibises would follow them from Egypt for over a hundred leagues into the desert to feed on the dung left at the encampments. By 1850, however, the species had disappeared from Egypt both as a breeding and migrant population, with the last, albeit questionable, sighting in 1864. An examination of the genetic diversity among mummified ibises suggested that there was no reduction in genetic diversity as would be caused if they were bred in captivity and further studies on isotopes suggest that the birds were not just wild caught but came from a wide geographic range.

The species did not breed in southern Africa before the beginning of the 20th century, but it has benefited from irrigation, dams, and commercial agricultural practices such as dung heaps, carrion and refuse tips. It began to breed in the early 20th century, and in the 1970s the first colonies of ibises were recorded in Zimbabwe and South Africa. Its population for example expanded 2-3-fold during the period between 1972 and 1995 in Orange Free State. It is now found throughout southern Africa. The species is a common resident in most parts of South Africa. Local numbers are swollen in summer by individuals migrating southwards from the equator.

Elsewhere in Africa it occurs throughout the continent south of the Sahara, but it is largely absent in the deserts of southwestern Africa (i.e. the Namib, the Karoo, the Kalahari) and probably the rainforests of the Congo. In west Africa it is fairly uncommon across the Sahel, except for the major floodplain systems. It can commonly found breeding along the Niger, in the Inner Niger Delta of Mali, the Logone of C.A.R., Lac Fitri in Chad, the Saloum Delta of Senegal, and other localities in relatively small numbers such as in The Gambia. It is common across eastern Africa and southern Africa. Large numbers can be found in the Sudd swamps and Lake Kundi in Sudan in the dry season. It is fairly widespread along the upper Nile River, and is quite common around Mogadishu, Somalia. In Tanzania there are a number of sites with 500 to 1,000+ birds, totalling some 20,000 birds.


The bird is also native to Yemen; in 2003 it bred in large numbers on small islands near Haramous and along the Red Sea coast near Hodeidah and Aden, where it was often found at waste-water treatment plants. It has been recorded nesting on a shipwreck in the Red Sea. It is also seen as a vagrant on Socotra. With the Yemen Civil War and famine, there have been no new census reports on the species in Yemen, though an estimate of approximately 30 mature individuals was given in 2015.

The species was fairly common in Iraq in the first half of the 20th century, but by the late 1960s it had become very scarce, with the population thought to number no more than 200 birds. The population was thought to have suffered greatly during the draining of the Mesopotamian Marshes of southeastern Iraq starting in the late 1980s, and feared to have disappeared entirely, but it has continuously been observed breeding in a colony in the Hawizeh Marshes (a part of the Mesopotamian Marshes) as of 2008, numbering up to 27 adults. It is also native to Kuwait, where it occurs as an extremely rare migrant, with only two known sightings, the last being a flock of 17 in 2007.

There are no records of the bird in Iran before the 1970s; however, small numbers were found overwintering in Khuzestan in 1970. Since the 1990s numbers appear to have slowly increased to a few dozen.

Introduced
The first African sacred ibises brought to Europe were two imported from Egypt to France in the mid-1700s. In the 1800s the first escapes were sighted in Europe (in Austria, Italy). In the 1970s it became fashionable for many zoos in Europe and elsewhere to keep their birds in free-flying colonies, which were allowed to forage in the area but would return to roost in the zoo every day. As such feral populations were established in Italy, France, Spain, Portugal, the Netherlands, the Canary Islands, Florida, Taiwan, the United Arab Emirates and possibly Bahrain.

Some studies indicate that the introduced populations in Europe have significant economic and ecological impacts, while others suggest that they constitute no substantial threat to native European bird species.

Europe
In Europe, the African sacred ibis is included since 2016 in the list of Invasive Alien Species of Union concern (the Union list). This implies that this species cannot be imported, bred, transported, commercialized, or intentionally released into the environment in the whole of the European Union.

In France the African sacred ibises have become established along its Atlantic coast following the feral breeding of birds which were the offspring of a large free-flying population originating from the Branféré Zoological Gardens in southern Brittany. The first successful breeding was in 1993 at two sites, the Golfe du Morbihan and Lac de Grand-Lieu, 25 km (16 mi) and 70 km (43 mi) respectively from Branféré. By 2005 the Atlantic French breeding. 

3-12-2015 JURONG, SINGAPORE - WOOD DUCK (FEMALE) (Aix sponsa)


The wood duck or Carolina duck (Aix sponsa) is a species of perching duck found in North America. The drake wood duck is one of the most colorful North American waterfowls.

The wood duck is a medium-sized perching duck. A typical adult is from 47 to 54 cm (19 to 21 in) in length with a wingspan of between 66 and 73 cm (26 and 29 in). The wood duck's weight ranges from 454–862 grams (16.0–30.4 oz). This is about three-quarters the length of an adult mallard. It shares its genus with the Asian mandarin duck (Aix galericulata).

The adult male has stunning multicolored iridescent plumage and red eyes, with a distinctive white flare down the neck. The female, less colorful, has a white eye-ring and a whitish throat. Both adults have crested heads. The speculum is iridescent blue-green with a white border on the trailing edge.

The male's call is a rising whistle, jeeeeee; the females utter a drawn-out, rising squeal, do weep do weep, when flushed, and a sharp cr-r-ek, cr-e-ek for an alarm call.
