4-5-2015 VILLALONGA TUNNELS, VALENCIA - IBERIAN GREEN FROG (Pelophylax perezi)


The Perez's frog (Pelophylax perezi), also known as Iberian waterfrog, Iberian green frog or Coruna frog, is a species of frog in the family Ranidae. It is native to southern France, Portugal, Spain, and has been introduced to the Canary and Balearic Islands, Madeira, the United Kingdom, and the Azores. In the Iberian Peninsula it is widespread and common.

Its natural habitats are temperate forests, temperate shrubland, Mediterranean-type shrubby vegetation, rivers, intermittent rivers, swamps, freshwater lakes, intermittent freshwater lakes, freshwater marshes, intermittent freshwater marshes, sandy shores, arable land, and urban areas. It is not considered threatened by the IUCN.


A medium-sized, stout frog; snout-vent length is usually from 40 to 70 mm, but sometimes is longer than 10 cm (Docampo and Milagrosa-Vega 1988; González de la Vega 1988). The head is as long as wide, with prominent eyes located in dorsal position very close to each other. The tympanum is well marked, about 1/2 to 3/4 the eye diameter (Salvador and García-París 2001). Toes have well developed webbing. Skin is either smooth or slightly rough, with well-formed dorsolateral folds.

The dorsal coloration is very variable, usually green but also brown or grayish to dark gray. They usually show a vertebral stripe, mostly yellow or green. Two irregular rows of dark, rectangular spots are present on both sides of the vertebral stripe. These spots are also present on the rear limbs, sometimes forming a banded pattern. Some individuals lack both the spots and the vertebral stripe. Ventrally they are white with a variable number of dark spots. Males are smaller than females and have stronger forelimbs. They have gray vocal sacs than can be appreciated even when they are not in use.


Tadpoles grow up to 111 mm total length (Salvador 1985), but usually measure between 60-70 mm (Barbadillo et al. 1999). The spiracle is sinistral and the anus open on the right side of the base of the tail. Marginal papillae are absent from the upper side of the mouth. Denticles are arranged in a variable number of single rows (Llorente et al. 1994), but the most common formula is 2(2)/3(1). The dorsal fin is low, starting at the level of the spiracle. The tip of the tail is pointed. Ground coloration is green or light brown, with small, dark dots. These dots are denser and larger in the tail fin. The tail presents a typical pattern with three longitudinal dark stripes. The ventral coloration is white.

29-4-2015 MONTE CORONA, VALENCIA - SIERRA NEVADA OCELLATED LIZARD (Timon nevadensis)


Timon nevadensis, the Sierra Nevada lizard, is a species of lizard in the family Lacertidae. It is endemic to Spain. It is sometimes considered a subspecies of the ocellated lizard.
Formerly, Timon nevadensis had been regarded as subspecies of Timon lepidus but it has been put into species rank in 2013. Its distribution range is limited to the Sierra Nevada and the Spanish east coast, reaching the Alicante Province in the north.

The Sierra Nevada Ocellated Lizard is an impressive but terribly shy Lacertid. In particular, adult specimens may have flight distances of more than 20 meters. These lizards occur in high altitude mountain areas as well as in coastal dunes and agricultural land.


Adult specimens differ from Timon lepidus by the grey or brown basic coloration with no or reduced black markings.

Juveniles and subadults of Timon nevadensis frequently show dark edges on the labial scales which lack in juvenile Timon lepidus. However, there seem to exist populations with intermediate characteristics.

Within its distribution range, Timon nevadensis cannot be confused with other lizards, due to its big size of adults and the distinct white spot pattern of the juveniles.


23-3-2015 PENANG HILLS, MALAYSIA - LONG TAILED MACAQUE (Macaca fascicularis)


The crab-eating macaque (Macaca fascicularis), also known as the long-tailed macaque and referred to as the cynomolgus monkey in laboratories, is a cercopithecine primate native to Southeast Asia. A species of macaque, the crab-eating macaque has a long history alongside humans. The species has been variously seen as an agricultural pest, a sacred animal, and, more recently, the subject of medical experiments.

The crab-eating macaque lives in matrilineal social groups of up to eight individuals dominated by females. Male members leave the group when they reach puberty. It is an opportunistic omnivore and has been documented using tools to obtain food in Thailand and Myanmar. The crab-eating macaque is a known invasive species and a threat to biodiversity in several locations, including Hong Kong and western New Guinea. The significant overlap in macaque and human living space has resulted in greater habitat loss, synanthropic living, and inter- and intraspecies conflicts over resources.


Macaca comes from the Portuguese word macaco, which was derived from makaku, a word in Ibinda, a language of Central Africa (kaku means monkey in Ibinda). The specific epithet fascicularis is Latin for a small band or stripe. Sir Thomas Raffles, who gave the animal its scientific name in 1821, did not specify what he meant by the use of this word.

In Indonesia and Malaysia, the crab-eating macaque and other macaque species are known generically as kera, possibly because of their high-pitched cries.


The crab-eating macaque has several common names. It is often referred to as the long-tailed macaque due to its tail, which is often longer than its body. The name crab-eating macaque refers to its being often seen foraging beaches for crabs. Another common name for M. fascicularis is the cynomolgus monkey, from the name of a race of humans with long hair and handsome beards who used dogs for hunting according to Aristophanes of Byzantium, who seemingly derived the etymology of the word cynomolgus from the Greek κύων, cyon 'dog' (gen. cyno-s) and the verb ἀμέλγειν, amelgein 'to milk' (adj. amolg-os), by claiming that they milked female dogs. This name is commonly used in laboratory settings.


The crab-eating macaque's native range encompasses most of mainland Southeast Asia, from extreme southeastern Bangladesh south through the Malay Peninsula and Singapore, the Maritime Southeast Asia islands of Sumatra, Java, and Borneo, offshore islands, the islands of the Philippines, and the Nicobar Islands in the Bay of Bengal. This primate is a rare example of a terrestrial mammal that violates the Wallace line, being found out across the Lesser Sunda Islands. It lives in a wide variety of habitats, including primary lowland rainforests, disturbed and secondary rainforests, shrubland, and riverine and coastal forests of nipa palm and mangrove. It also easily adjusts to human settlements and is considered sacred at some Hindu temples and on some small islands, but as a pest around farms and villages. Typically, it prefers disturbed habitats and forest periphery.


The body length of the adult, which varies among subspecies, is 38–55 cm (15–22 in) with relatively short arms and legs. Males are considerably larger than females, weighing 5–9 kg (11–20 lb) compared to the 3–6 kg (6.6–13.2 lb) of females. The tail is longer than the body, typically 40–65 cm (16–26 in), which is used for balance when they jump distances up to 5 m (16 ft). The upper parts of the body are dark brown with light golden brown tips. The under parts are light grey with a dark grey/brown tail. Crab-eating macaques have backwards-directed crown hairs which sometimes form short crests on the midline. Their skin is black on their feet and ears, whereas the skin on the muzzle is a light grayish pink color. The eyelids often have prominent white markings and sometimes there are white spots on the ears. Males have a characteristic mustache and cheek whiskers, while females have only cheek whiskers. Crab-eating macaques have a cheek pouch which they use to store food while foraging. Females show no perineal swelling.


Macaques live in social groups that contain three to 20 females, their offspring, and one or many males. The groups usually have fewer males than females. In social groups of macaques, a clear dominance hierarchy is seen among females. These ranks remain stable throughout the female's lifetime and also can be sustained through generations of matrilines. Females have their highest birth rates around 10 years of age and completely stop bearing young by age 24.
The social groups of macaques are female-bonded, meaning the males will disperse at the time of puberty. Thus, group relatedness on average appears to be lower than compared to matrilines. More difference in relatedness occurs when comparing high-ranking lineages to lower ranking lineages, with higher-ranking individuals being more closely related to one another. Additionally, groups of dispersing males born into the same social groups display a range of relatedness, at times appearing to be brothers, while at other times appearing to be unrelated.

In addition to the matrilineal dominance hierarchy, male dominance rankings also exist. Alpha males have a higher frequency of mating compared to their lower-ranking conspecifics. The increased success is due partially to his increased access to females and also due to female preference of an alpha male during periods of maximum fertility. Though females have a preference for alpha males, they do display promiscuous behavior. Through this behavior, females risk helping to rear a non-alpha offspring, yet benefit in two specific ways, both in regard to aggressive behavior. First, a decreased value is placed on one single copulation. Moreover, the risk of infanticide is decreased due to the uncertainty of paternity.

19-3-2015 JURONG, SINGAPORE - DALMATIAN PELICAN (Pelecanus crispus)


Dalmatian pelican (Pelecanus crispus) – more than a pink pelican, distinguished by the absence of pink tones in the plumage. On the head and the upper side of the neck are long and twisted curly feathers which form the likeness of a mane. It takes off fairly easily, pushing the water with both feet, but when it has a catch in its throat bag, gets up with difficulty.


The Dalmatian pelican (Pelecanus crispus) is the largest member of the pelican family, and perhaps the world's largest freshwater bird, although rivaled in weight and length by the largest swans. They are elegant soaring birds, with wingspans rivaling those of the great albatrosses, and their flocks fly in graceful synchrony. With a range spanning across much of Central Eurasia, from the Mediterranean in the West to the Taiwan Strait in the East, and from the Persian Gulf in the South to Siberia in the North, it is a short-to-medium-distance migrant between breeding and overwintering areas. No subspecies are known to exist over its wide range, but based on size differences, a Pleistocene paleosubspecies, P. c. palaeocrispus, has been described from fossils recovered at Binagady, Azerbaijan.


As with other pelicans, the males are larger than the females, and likewise their diet is mainly fish. Their curly nape feathers, grey legs and silvery-white plumage are distinguishing features, and the wings appear solid grey in flight. The adults acquire a drabber plumage in winter, however, when they may be mistaken for great white pelicans. Their harsh vocalizations become more pronounced during the mating season. They breed across the Palearctic from southeastern Europe to Russia, India and China in swamps and shallow lakes. They usually return to traditional breeding sites, where they are less social than other pelican species. Their nests are crude heaps of vegetation, which are placed on islands or on dense mats of vegetation.

The species' numbers underwent a dramatic decline during the 20th century, partly due to land use, disturbance and poaching activities. The core population survives in Russia, but in its Mongolian range it is critically endangered. Removal of power lines to prevent collisions or electrocution and construction of nesting platforms or rafts have reversed declines locally.


The Dalmatian pelican is found in lakes, rivers, deltas and estuaries. Compared to the great white pelican, the Dalmatian is not as tied to lowland areas and will nest in suitable wetlands with many elevations. It is less opportunistic in breeding habitat selection than the great white, usually returning to a traditional breeding site year after year unless it becomes completely unsuitable. During the winter, Dalmatian pelicans usually stay on ice-free lakes in Europe or jheels (seasonal lakes) in India. They also visit, typically during winter, inshore areas along sheltered coasts for feeding.

29-4-2015 MONTE CORONA, VALENCIA - WHITE WAGTAIL (Motacilla alba)



The White wagtail (Motacilla alba) is a small insectivorous bird of the open country, often near habitation and water. It prefers bare areas for feeding, where it can see and pursue its prey. In urban areas, it has adapted to foraging on paved areas such as car parks. It is the national bird of Latvia and has been featured on the stamps of several countries.

23-3-2015 PENANG, MALAYSIA - WHITE BREASTED KINGFISHER (Halcyon smyrnensis)


The white-throated kingfisher (Halcyon smyrnensis) also known as the white-breasted kingfisher is a tree kingfisher, widely distributed in Asia from the Sinai east through the Indian subcontinent to China and Indonesia. This kingfisher is a resident over much of its range, although some populations may make short distance movements. It can often be found well away from water where it feeds on a wide range of prey that includes small reptiles, amphibians, crabs, small rodents and even birds. During the breeding season they call loudly in the mornings from prominent perches including the tops of buildings in urban areas or on wires.


The white-throated kingfisher is a common species in a variety of habitats, mostly open country in the plains (but has been seen at 7500 ft in the Himalayas with trees, wires or other perches. The range of the species is expanding.

This kingfisher is widespread and populations are not threatened. Average density of 4.58 individuals per km2. has been noted in the Sundarbans mangroves.

23-4-2015 ISTANBUL, TURKEY - HOODED CROW (Corvus cornix)


The hooded crow (Corvus cornix), also called the scald-crow or hoodie, is a Eurasian bird species in the genus Corvus. Widely distributed, it is found across Northern, Eastern, and Southeastern Europe, as well as parts of the Middle East. It is an ashy grey bird with black head, throat, wings, tail, and thigh feathers, as well as a black bill, eyes, and feet. Like other corvids, it is an omnivorous and opportunistic forager and feeder.

The hooded crow is so similar in morphology and habits to the carrion crow (Corvus corone) that for many years they were considered by most authorities to be geographical races of one species. Hybridization observed where their ranges overlapped added weight to this view. However, since 2002, the hooded crow has been elevated to full species status after closer observation; the hybridisation was less than expected and hybrids had decreased vigour. Within the hooded crow species, four subspecies are recognized, with one, the Mesopotamian crow, possibly distinct enough to warrant species status itself.


The hooded crow breeds in northern and eastern Europe, and closely allied forms inhabit southern Europe and western Asia. Where its range overlaps with that of the carrion crow, as in northern Britain, Germany, Denmark, northern Italy, and Siberia, their hybrids are fertile. However, the hybrids are less well-adapted than purebred birds (one of the reasons behind its reclassification as a distinct species from the carrion crow). Little or no interbreeding occurs in some areas, such as Iran and central Russia.

In the British Isles, the hooded crow breeds regularly in Scotland, the Isle of Man, and the Scottish Islands; it also breeds widely in Ireland. In autumn, some migratory birds arrive on the east coast of Britain. In the past, this was a more common visitor.




19-3-2015 JURONG, SINGAPORE - RED WINGED STARLING (FEMALE) (Onychognathus morio)




The red-winged starling (Onychognathus morio) is a bird of the starling family Sturnidae native to eastern Africa from Ethiopia to the Cape in South Africa. An omnivorous, generalist species, it prefers cliffs and mountainous areas for nesting, and has moved into cities and towns due to similarity to its original habitat.

The male of this 27–30-centimetre (11–12 in) long starling has mainly iridescent black plumage, with chestnut flight feathers, which are particularly noticeable in flight. The female has an ash-grey head and upper breast. The juvenile resembles the male, but is less glossy than the adults, and has brown rather than dark red eyes. The Ethiopian subspecies O. m. rupellii is longer-tailed than the nominate form and intergrades with it.

This species has a number of whistled calls, but the most familiar is the contact call, cher-leeeoo.

This starling may be confused with other similar starling species, such as its sister species the pale-winged starling. The difference between the two is that the red-winged has rufous primaries while the pale-winged has whitish primaries edged with orange. The pale-winged has a bright red or orange eye, while the red-winged's is dark, almost black. Only the female of the red-winged has a grey head.


The range runs down eastern Africa from Ethiopia to the Cape, Kwa-Zulu Natal and Gauteng in South Africa. This species has a wide habitat tolerance. It may be found in forest, savannah, grassland, wetlands, fynbos, farmlands and commercial plantations, as well as urban centres. It is now common in many urban areas, due to the similarity between the structure of tall buildings and houses as nest sites with the cliffs of its original habitat. It may also nest in residential areas, breeding in roofs and apertures and up house eaves.


Like other starlings, the red-winged starling is an omnivore, taking a wide range of seeds, berries, nectar from plants such as Aloe and Schotia brachypetala, and invertebrates, such as the beetle species Pachnoda sinuata. They may take nestlings and adults of certain bird species, such as the African palm swift. It will also scavenge on carrion and human food scrap.

The red-winged starling will obviously only perch on plant structures that will be able to support its weight; therefore when taking nectar it will choose certain species with strong, robust racemes with easily accessible flowers, such as that of Aloe ferox and Aloe marlothii, and not Aloe arborescens. Large flowers that can support the bird's weight, such as that of Strelitzia nicolai and certain Protea species, are also chosen.

Fruit species that this species may feed on include figs, such as the sycamore fig and others, marulas, date palm fruit, berries from species such as wild olive Olea europaea subsp. cuspidata and Euphorbia, and commercial fruit such as apples, grapes, citruses and others.

In rural areas, red-winged starlings are often spotted perching on livestock and game, such as cattle, klipspringers and giraffes, a trait shared by the pale-winged starling, and may take insects and ectoparasites such as ticks, much in the manner of oxpeckers.

30-3-2015 KERALA, INDIA - WHITE BREASTED KINGFISHER (Halcyon smyrnensis)



White-throated kingfishers are found in Asia from the Sinai east through the Indian subcontinent to China and Indonesia. They are mainly resident over much of their range, although some populations may make short-distance movements. White-throated kingfishers live in a variety of habitats, mostly open country in the plains with trees, wires, or other perches; however, they have also been seen in the Himalayas. These birds also occur in tropical forests, mangrove edges, swamps, ponds, plantations, rice fields, and farmland.

18-4-2015 SEA OF GALILEE, ISRAEL - WHITE STORK (Ciconia ciconia)


The white stork (Ciconia ciconia) is a large bird in the stork family, Ciconiidae. Its plumage is mainly white, with black on the bird's wings. Adults have long red legs and long pointed red beaks, and measure on average 100–115 cm (39–45 in) from beak tip to end of tail, with a 155–215 cm (61–85 in) wingspan. The two subspecies, which differ slightly in size, breed in Europe (north to Finland), northwestern Africa, southwestern Asia (east to southern Kazakhstan) and southern Africa. The white stork is a long-distance migrant, wintering in Africa from tropical Sub-Saharan Africa to as far south as South Africa, or on the Indian subcontinent. When migrating between Europe and Africa, it avoids crossing the Mediterranean Sea and detours via the Levant in the east or the Strait of Gibraltar in the west, because the air thermals on which it depends for soaring do not form over water.

A carnivore, the white stork eats a wide range of animal prey, including insects, fish, amphibians, reptiles, small mammals and small birds. It takes most of its food from the ground, among low vegetation, and from shallow water. It is a monogamous breeder, and both members of the pair build a large stick nest, which may be used for several years. Each year the female can lay one clutch of usually four eggs, which hatch asynchronously 33–34 days after being laid. Both parents take turns incubating the eggs and both feed the young. The young leave the nest 58–64 days after hatching, and continue to be fed by the parents for a further 7–20 days.


The white stork has been rated as least concern by the International Union for Conservation of Nature (IUCN). It benefited from human activities during the Middle Ages as woodland was cleared, but changes in farming methods and industrialisation saw it decline and disappear from parts of Europe in the 19th and early 20th centuries. Conservation and reintroduction programs across Europe have resulted in the white stork resuming breeding in the Netherlands, Belgium, Switzerland, Sweden and the United Kingdom. It has few natural predators, but may harbour several types of parasite; the plumage is home to chewing lice and feather mites, while the large nests maintain a diverse range of mesostigmatic mites. This conspicuous species has given rise to many legends across its range, of which the best-known is the story of babies being brought by storks.

23-4-2015 ISTANBUL, TURKEY - HOUSE SPARROW (MALE) (Passer domesticus)


The House sparrow (Passer domesticus) is a small passerine bird found in most parts of the world. The extent of its range makes it the most widely distributed wild bird on the planet. Because of its numbers, ubiquity, and association with human settlements, the House sparrow is culturally prominent. It is extensively, and usually unsuccessfully, persecuted as an agricultural pest. It has also often been kept as a pet and was a food item. Though it is widespread and abundant, its numbers have declined in some areas.

The plumage of the House sparrow is mostly different shades of grey and brown. The sexes exhibit strong dimorphism: the female is mostly buffish above and below, while the male has boldly colored head markings, a reddish back, and grey underparts. The male has a dark grey crown from the top of its bill to its back, and chestnut brown flanking its crown on the sides of its head. It has black around its bill, on its throat, and on the spaces between its bill and eyes (lores). It has a small white stripe between the lores and crown and small white spots immediately behind the eyes (postoculars), with black patches below and above them. The underparts are pale grey or white, as are the cheeks, ear coverts, and stripes at the base of the head. The upper back and mantle are a warm brown, with broad black streaks, while the lower back, rump, and upper tail coverts are greyish brown. The male is duller in fresh nonbreeding plumage, with whitish tips on many feathers. Wear and preening expose many of the bright brown and black markings, including most of the black throat and chest patch, called the "bib" or "badge". The male's bill is dark grey, but black in the breeding season. The female has no black markings or grey crowns. Its upperparts and head are brown with darker streaks around the mantle and a distinct pale supercilium. Its underparts are pale grey-brown. The female's bill is brownish-grey and becomes darker in breeding plumage approaching the black of the male's bill. Juveniles are similar to adult female, but deeper brown below and paler above, with paler and less defined supercilia. Juvenile males tend to have darker throats and white postoculars like adult males, while juvenile females tend to have white throats. The bills of young birds are light yellow to straw, paler than the female's bill.


House sparrows are native to most of Europe, the Mediterranean Basin, a large part of Asia, and parts of North Africa. These birds are strongly associated with human habitation and can live in urban or rural settings. They are found in widely varied habitats and climates but typically avoid extensive woodlands, grasslands, and deserts away from human development. The only terrestrial habitats that House sparrows do not inhabit are dense forests and tundra.

House sparrows are very social birds. They are gregarious during all seasons when feeding, often forming flocks with other species of birds. They roost communally and while breeding nests are usually grouped together in clumps. House sparrows also engage in social activities such as dust or water bathing and "social singing", in which birds call together in bushes. These little birds feed mostly on the ground, but they flock in trees and bushes. At feeding stations and nests, females are dominant despite their smaller size, and they can fight over males in the breeding season. On the ground, House sparrows typically hop rather than walk; they can also swim when forced to do so by pursuit from predators. Most House sparrows do not move more than a few kilometers during their lifetimes. However, limited migration occurs in all regions. Some young birds disperse long distances, especially on coasts, and mountain birds move to lower elevations in winter. House sparrows are highly noisy. Most of their vocalizations are variations of their short chirping call that may sound like 'chirrup', 'tschilp', or 'philip'; this note is made as a contact call by flocking or resting birds, or by males to proclaim nest ownership and invite pairing. Much communal chirping occurs before and after the birds settle in the roost in the evening, as well as before the birds leave the roost in the morning. Aggressive males give a trilled version of their call, transcribed as 'chur-chur-r-r-it-it-it-it'. This call is also used by females in the breeding season, to establish dominance over males while displacing them to feed young or incubate eggs.

9-4-2015 MUSCAT, OMAN - COMMON SANDPIPER (Actitis hypoleucos)



The common sandpiper (Actitis hypoleucos ) is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper (A. macularia ), make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a basal species of the closely related shank genus Tringa.

The adult is 18–20 cm (7.1–7.9 in) long with a 32–35 cm (13–14 in) wingspan. It has greyish-brown upperparts, white underparts, short dark-yellowish legs and feet, and a bill with a pale base and dark tip. In winter plumage, they are duller and have more conspicuous barring on the wings, though this is still only visible at close range. Juveniles are more heavily barred above and have buff edges to the wing feathers.


The common sandpiper breeds across most of temperate and subtropical Europe and Asia, and migrates to Africa, southern Asia and Australia in winter. The eastern edge of its migration route passes by Palau in Micronesia, where hundreds of birds may gather for a stop-over. They depart the Palau region for their breeding quarters around the last week of April to the first week of May.

The common sandpiper forages by sight on the ground or in shallow water, picking up small food items such as insects, crustaceans and other invertebrates; it may even catch insects in flight.

It nests on the ground near freshwater. When threatened, the young may cling to their parent's body to be flown away to safety.


26-4-2015 MONTE CORONA - WHITE WAGTAIL (Motacilla alba)


The White wagtail is a slender bird with the characteristic long, constantly wagging tail of its genus. There are a number of other subspecies, some of which may have arisen because of partial geographical isolation, such as the resident British and Irish form, the pied wagtail M. a. yarrellii, which now also breeds in adjacent areas of the neighbouring European mainland. The Pied wagtail exchanges the grey colour of the nominate form with black (or very dark grey in females), but is otherwise identical in its behaviour. Other subspecies, the validity of some of which is questionable, differ in the colour of the wings, back, and head, or other features. Some races show sexual dimorphism during the breeding season. As many as six subspecies may be present in the wintering ground in India or Southeast Asia and here they can be difficult to distinguish.


White wagtails breed throughout Eurasia, only being absent in the Arctic. They also breed in the mountains of Morocco and western Alaska. These birds are residents in the milder parts of their range such as western Europe and the Mediterranean, but migratory in much of the rest of their range. Northern European breeders winter around the Mediterranean and in tropical and subtropical Africa, and Asiatic birds move to the Middle East, India, and Southeast Asia. Birds from the North American population also winter in tropical Asia. White wagtails occupy a wide range of habitats but are absent from deserts. They inhabit grasslands, seashores, rocky shorelines, sand beaches, tidepools, rivers, lakeshores, farmland, gardens, and parks. They are also often found in towns and villages.

29-3-2015 COCHIN, INDIA - INDIAN POND HERON (Ardeola grayii)


The Indian pond heron or paddybird (Ardeola grayii) is a small heron. It is of Old World origins, breeding in southern Iran and east to the Indian subcontinent, Burma, and Sri Lanka. They are widespread and common but can be easily missed when they stalk prey at the edge of small water-bodies or even when they roost close to human habitations.

They are distinctive when they take off, with bright white wings flashing in contrast to the cryptic streaked olive and brown colours of the body. Their camouflage is so excellent that they can be approached closely before they take to flight, a behaviour which has resulted in folk names and beliefs that the birds are short-sighted or blind.


Indian pond herons are stocky with short necks, short thick bills and buff-brown backs. In summer, adults have long neck feathers. Their appearance is transformed from dull colours when they take to flight and the white of the wings makes them very prominent. They are very similar to the squacco herons, Ardeola ralloides, but darker backed. To the east of their range, they are replaced by the Chinese pond herons, Ardeola bacchus.

During the breeding season, there are records of individuals with red legs. The numbers do not suggest that this is a normal change for adults during the breeding season and some have suggested the possibility of it being genetic variants.

Erythristic plumage has been noted. The race phillipsi has been suggested for the populations found in the Maldives, without much acceptance. It forms a superspecies with the closely related Chinese pond heron, Javan pond heron and the Madagascar pond heron.
They are usually silent but may make a harsh croak in alarm when flushed or near their nests.

This bird was first described by Colonel W. H. Sykes in 1832 and given its scientific name in honour of John Edward Gray. Karyology studies indicate that pond herons have 68 chromosomes. 


They are very common in India, and are usually solitary foragers but numbers of them may sometimes feed in close proximity during the dry seasons when small wetlands have a high concentration of prey. They are semi-colonial breeders. They may also forage at garbage heaps. During dry seasons, they sometimes take to foraging on well watered lawns or even dry grassland. When foraging, they allow close approach and flush only at close range. They sometimes form communal roosts, often in avenue trees over busy urban areas.


The Indian pond heron's feeding habitat is marshy wetlands. They usually feed at the edge of ponds but make extensive use of floating vegetation such as water hyacinth to access deeper water. They may also on occasion swim on water or fish from the air and land in deeper waters. They have also been observed to fly and capture fishes leaping out of water. Sometimes, they fly low over water to drive frogs and fishes towards the shore before settling along the shoreline. They have been noted to pick up crumbs of bread and drop them on the water surface to bait fishes.

The primary food of these birds includes crustaceans, aquatic insects, fishes, tadpoles and sometimes leeches (Herpobdelloides sp.). Outside wetlands, these herons feed on insects (including crickets, dragonflies and bees), fish (Barilius noted as important in a study in Chandigarh) and amphibians.


The breeding season begins with the onset of the monsoons. They nest in small colonies, often with other wading birds, usually on platforms of sticks in trees or shrubs. Most nests are built at a height of about 9 to 10 m in large leafy trees. The nest material is collected by the male while the female builds the nest. Three to five eggs are laid. The eggs hatch asynchronously, taking 18 to 24 days to hatch. Both parents feed the young. Fish are the main diet fed to young. Nest sites that are not disturbed may be reused year after year.


The habit of standing still and flushing only at the last moment has led to widespread folk beliefs that they are semi-blind and their name in many languages includes such suggestions. In Sri Lanka the bird is called kana koka which translates as "half-blind heron" in the Sinhala language. The Hindustani phrase "bagla bhagat" has been used to describe a "wolf in sheep's clothing" or a hypocrite appearing like a meditating saint and occurs in a Marathi proverb. The paddy-bird also appears as a character in the Hitopadesha where, in one story, it takes injury to itself to save a king. The bird was noted by Anglo-Indian naturalist-writers for the surprising transformation in colours. Phil Robinson described the bird as one that sits all dingy gray and flies all white. It is said to have been eaten by many in India in former times.

During the height of the plume trade, feathers were collected from the "paddy bird" and exported to Britain.

23-3-2015 PENANG, MALAYSIA - COMMON FLAMEBACK (Dinopium javanense)


The common flameback (Dinopium javanense), also referred to as the common goldenback, is a small (28–30 cm), three-toed woodpecker in the family Picidae, found throughout South and Southeast Asia.

As shy and secretive birds, common flamebacks are unlikely to be found in urban areas. They live in a variety of habitats, ranging from moist open forests, to scrubs, and mangroves. Although they generally enjoy lowlands, they can reach altitudes of 1700m above sea level in India and in those cases prefer living in pine forests.

Their distribution ranges across Southeast Asia, from the Western Ghats in India to the Indochinese peninsula and several of the Greater Sunda Islands.

19-3-2015 JURONG, SINGAPORE - AMERICAN FLAMINGO (Phoenicopterus ruber)


The American flamingo (Phoenicopterus ruber) is a large species of flamingo native to the West Indies, northern South America (including the Galápagos Islands) and the Yucatan Peninsula. It is closely related to the greater flamingo and Chilean flamingo, and was formerly considered conspecific with the greater flamingo, but that treatment is now widely viewed (e.g. by the American and British Ornithologists' Unions) as incorrect due to a lack of evidence. It is also known as the Caribbean flamingo, although it is also present in the Galápagos Islands. It is the only flamingo that naturally inhabits North America.

It is a cultural icon for the U.S. state of Florida, where it was formerly abundant in the southernmost regions, although it was largely extirpated by 1900 and is now only an uncommon visitor with a few small, potential resident populations.


The American flamingo breeds in South America (in the Galápagos Islands of Ecuador, coastal Colombia and Venezuela, and northern Brazil), in the West Indies (Trinidad and Tobago, Cuba, Jamaica, Hispaniola (the Dominican Republic and Haiti), The Bahamas, the Virgin Islands, and the Turks and Caicos Islands), and tropical and subtropical areas of continental North America (along the northern coast of the Yucatán Peninsula in Mexico, and formerly southern Florida in the United States). It is a vagrant to Puerto Rico, Anguilla, Barbados, Honduras, and (following its extirpation) Florida, although some Florida populations are now thought to be year-round residents. The population in the Galápagos Islands differs genetically from that in the Caribbean; the Galápagos flamingos are significantly smaller, exhibit sexual dimorphism in body shape, and lay smaller eggs. They are sometimes separated as Phoenicopterus ruber glyphorhynchus.

Its preferred habitats are similar to those of its relatives: saline lagoons, mudflats, and shallow, brackish coastal or inland lakes. An example habitat is the Petenes mangroves ecoregion of the Yucatán.


Like other flamingo species, American flamingos will migrate short distances to ensure that they get enough food or because their current habitat has been disturbed in some way. One habitat disturbance that has been observed to cause flamingos to leave their feeding grounds is elevated water levels. These conditions make it difficult for Phoenicopterus ruber to wade, hindering their ability to access food. The flamingos will then abandon their feeding grounds in search of an alternate food source. While the flights are not as long as other migratory birds, flamingos still fly for periods without eating.


Mating and bonding behaviors of P. ruber individuals have been extensively studied in captivity. The American flamingo is usually monogamous when selecting a nest site, and incubating and raising young; however, extra-pair copulations are frequent.

While males usually initiate courtship, females control the process. If interest is mutual, a female walks by the male, and if the male is receptive, he walks with her. Both parties make synchronized movements until one member aborts this process. For low-intensity courtships, males and females walk in unison with their heads raised. In high-intensity courtships, males and females walk at a quick pace with their heads dropped in a false feeding posture. This high-intensity courtship stops at any point if either bird turns and the other does not follow, the heads are raised, unison movements are stopped, or the pace of movement is slowed. If the female is ultimately receptive to copulation, she stops walking and presents for the male. Long-term pairs do not frequently engage in courtship behaviors or in-group display. Pairs often stand, sleep, and eat in close proximity.


Courtship is most often seen among individuals that change partners often or are promiscuous. A spectrum of pairing relationships is seen. Some birds have a long-term partner throughout the year; others form pairs during periods of courtship and nest attendance. How long a relationship lasts is affected by many factors, including addition and removal of adults, maturation of juveniles, and occurrence of trios and quartets. In most pairs, both individuals usually construct and defend the nest site. In rare cases, one individual undertakes both duties. Within trios, the dominant pair begins the nesting process by choosing and then defending the site.

20-3-2015 BOTANICAL GARDENS, SINGAPORE - YELLOW VENTED BULBUL (Pycnonotus goiavier)


The yellow-vented bulbul (Pycnonotus goiavier), or eastern yellow-vented bulbul, is a member of the bulbul family of passerine birds. It is a resident breeder in southeastern Asia from Indochina to the Philippines. It is found in a wide variety of open habitats but not the deep forest. It is one of the most common birds in cultivated areas. They appear to be nomadic and roam from place to place regularly.

The yellow-vented bulbul was originally classified in the genus Muscicapa.

19-3-2015 JURONG, SINGAPORE - SILVER EARED MESIA (Leiothrix argentauris)

                              

The silver-eared mesia (Leiothrix argentauris) is a species of bird from South East Asia.
The species is generally resident although it has been reported as a winter migrant to Nameri National Park in Assam, India, which implies that the species may be an altitudinal migrant. The species has been introduced to Hong Kong from captive stock derived from caged birds.
