28-11-2016 JURONG, SINGAPORE - STRAW NECKED IBIS (Threskiornis spinicollis)

The straw-necked ibis (Threskiornis spinicollis) is a bird of the ibis and spoonbill family Threskiornithidae. It can be found throughout Australia, New Guinea, and parts of Indonesia. Adults have distinctive straw-like feathers on their necks.

Straw-necked ibises are commonly found throughout Australia, nesting at least occasionally in all mainland states and territories, except in the arid interior. They are most abundant on the east coast, and are vagrant to New Zealand, Norfolk Island and Lord Howe Island. They are less frequently seen in New Guinea, Indonesia, and occasionally in Tasmania and other islands of the Bass Strait.

Found around shallow freshwater wetlands, cultivated pastures, edges of swamps and lagoons, and wet or dry grasslands. They tend to avoid arid and saltwater areas, and coastal mudflats. They are extremely nomadic, and are constantly on the move searching for suitable habitats. They are frequently seen standing on high branches of bare trees, silhouetted against the sky.

Straw-necked ibises are large birds, around 59–76 cm (23–30 in) long, with a bare black head and a long, downcurved black bill. They have a distinctive, highly iridescent plumage, which can appear fairly uniform dirty dark brown in indifferent light; the wings are dark, with an iridescent, multicoloured sheen in sunlight. They have a shiny blue-black back, with a metallic purple, green and bronze glow, and a dark collar. The upper neck is white, as are the underparts and the undertail; their legs are usually red near the top and dark grey toward the feet. Adults have straw-colored feathers on the neck, giving the bird its common name. Their wingspan is about 100–120 cm (39.5–47 in) and weight is generally 1.1–1.5 kg (2.5–3.5 lb).

Sexes are similar, although males have longer bills and females have a dark band across their upper breast. Juveniles have duller colors and shorter bills with less curvature, and lack the straw-like plumes on the neck.

Straw-neck ibises are partly migratory: some birds are sedentary, while others make seasonal or erratic movements when water conditions vary. Seasonal migrations are recorded from south-eastern and northern Australia, as well as from coast and inland wetlands in central Australia, and across the Torres Strait between north-eastern Australia and southern New Guinea. Non-breeding migrants arrive in western Australia and leave in autumn, the arrival dates are closely correlated with rainfall during the preceding spring. They typically fly in line or in V formation, reaching high altitudes during long-distance movements.

Vocalizations are made mainly around breeding colonies; calls are composed of croaks, barks and grunts. In flight, at intervals, they may produce a hoarse grunt. They feed in flocks of up to 200 birds; they probe in soil, mud, crevices, vegetation or shallow water.

Straw-necked ibises feed primarily on aquatic and terrestrial invertebrates, although their diets can vary. In shallow waters, straw-necked ibises feed on aquatic insects, molluscs, frogs, freshwater crayfish (Cherax) and fish. On land, they thrive on insects such as grasshoppers, crickets, and locusts, and are often called the Farmer's Friend because they eat pests that would otherwise eat farm crops. They also eat skinks and other small lizards, and small reptiles, as well as rodents.

Compared to the Australian white ibis, they have not adapted to a wide variety of food and are only rarely opportunistic scavengers of human waste. Citizen scientists have reported seeing them eat cane toads (Bufo marinus), avoiding being poisoned by flicking the toads about until they release the toxin which is their defence mechanism, then taking them to a creek to wash them.

Breeding season is highly variable, mainly influenced by water conditions. In southwestern Australia, it normally occurs from August to December; occasional breeding takes place in the north, but on a very small scale. Breeding has been observed for all months throughout the central and northern regions, usually occurring over the year following heavy rain in some areas.

They build a large, rough, cup-shaped nest of sticks and trampled plants among reeds, paperbarks, bulrushes, or trees over water. They breed in colonies, often with the Australian white ibis. Nests are used year after year. Clutches vary from 2–5 eggs, with an incubation period of around 24 to 25 days, by both parents. Both parents feed and care for the young, about 35 days after hatching. Feeding is by regurgitation and continues up to two weeks after leaving the nest.

28-11-2016 JURONG, SINGAPORE - ROSEATE SPOONBILL (Platalea ajaja)

The Roseate spoonbill (Platalea ajaja) is a gregarious wading bird of the ibis and spoonbill family, Threskiornithidae. It is a resident breeder in both South and North America. Plume hunting in the 18th and 19th centuries almost drove these beautiful birds to extinction.

Adult Roseate spoonbills have a bare greenish head and a white neck, back, and breast (with a tuft of pink feathers in the center when breeding), and are otherwise a deep pink. The colors can range from pale pink to bright magenta, depending on age, whether breeding or not, and location. Unlike herons, spoonbills fly with their necks outstretched, and they alternate groups of stiff, shallow wingbeats with glides.

Roseate spoonbills are resident breeders in South America mostly east of the Andes and in coastal regions of the Caribbean, Central America, Mexico, the Gulf Coast of the United States, and from central Florida's Atlantic coast at least as far north as South Carolina's Myrtle Beach. These birds inhabit coastal marshes, bays, lagoons, mangroves, and mudflats. They usually nest and roost in trees and shrubs near water.

Roseate spoonbills are gregarious birds and prefer to feed and fly in groups. They are active during the day spending many hours foraging in shallow fresh or coastal waters. The birds feed by swinging their bill from side to side as they steadily walk through the water, often in groups. Their spoon-shaped bill allows them to sift easily through mud feeling and looking for prey. The bill has sensitive nerve endings and once the birds feel the prey touch their bill they snap it closed. Roseate spoonbills roost in colonies often with other waders. They sleep standing, often on one leg with their head hidden under a shoulder. These birds are usually silent but when alarmed they will produce a low-pitched 'huh-huh-huh'; when feeding they may utter a very low, guttural sound.

28-11-2016 JURONG, SINGAPORE - RAINBOW LORIKEET (Trichoglossus haematodus)

The Rainbow lorikeet is a medium-sized colorful parrot. Its head is deep blue with a greenish-yellow nuchal collar, and the rest of the upper parts (wings, back, and tail) are green. The chest is orange/yellow in color. The belly is deep blue, and the thighs and rump are green. In flight a yellow wing-bar contrasts clearly with the red underwing coverts. The males and the females in this species are similar in appearance and juveniles have a black beak, which gradually brightens to orange in the adults.

Rainbow lorikeets are found along the eastern seaboard, from northern Queensland to South Australia. They live in rainforests, mangroves, woodlands, coastal bushes, and in urban areas.

Rainbow lorikeets are social, active, and noisy birds. They often travel together in pairs and occasionally respond to calls to fly as a flock, then disperse again into pairs. They are territorial and each pair defends its feeding and nesting area aggressively against other Rainbow lorikeets and other bird species. They chase off not only smaller birds but also larger birds such as the Australian magpie. Rainbow lorikeets feed and roost in treetops and rarely come to the ground. They are very strong flyers and daily travel up to 30 km between feeding and roosting sites.

Rainbow lorikeets are monogamous and remain paired for long periods, if not for life. In southern Australia, breeding usually occurs from late winter to early summer (August to January). In other parts of Australia, breeding has been recorded every month except March, varying from region to region due to changes in food availability and climate. Rainbow lorikeets may nest in various sites including hollows of tall trees such as eucalyptus, palm trunks, or overhanging rock. Pairs sometimes nest in the same tree with other Rainbow lorikeet pairs or even other bird species. The female lays a clutch of between 1 and 3 eggs, which she incubates alone for around 25 days. The chicks hatch altricial (helpless) and are tended by both parents. They fledge at 56-64 days of age but continue to be fed by their parents for another 2-3 weeks. Rainbow lorikeets start to breed when they are 12-15 months old and may produce up to 3 broods per season.

Despite being widespread throughout their native range, Rainbow lorikeets are threatened by habitat loss and capture for the international parrot trade.

According to IUCN, the Rainbow lorikeet is common and widespread throughout its range but no overall population estimate is available. Currently, this species is classified as Least Concern (LC) on the IUCN Red List but its numbers today are decreasing.

28-11-2016 JURONG, SINGAPORE - BLACK CAPPED LORY (Lorius lory)

The black-capped lory (Lorius lory ) also known as western black-capped lory or the tricolored lory, is a parrot found in New Guinea and adjacent smaller islands. It is a colourful and relatively robust lory (31 cm (12 in)). There are seven subspecies, all with green wings, red heads and body around the wing, a black cap, grey-black cere, yellow underwings, and blue legs and belly. Most also have a blue nape and mantle (area between wings on the back). It remains overall widespread and common, but the subspecies cyanuchen is relatively rare, with fewer than 5,000 individuals remaining.

Their black-capped lory inhabits the primary forest and forest edges in most lowland areas up to 1,000 m (3,300 ft) (sporadically to 1,750 m (5,740 ft)), but not monsoon forest or coconut plantations. It is usually found in pairs and occasionally in groups of 10 or more. Their diet includes pollen, nectar, flowers, fruit and insects.

28-11-2016 JURONG, SINGAPORE - ORIENTAL MAGPIE (Pica serica)

The Oriental magpie (Pica serica ) is a species of magpie found from south-eastern Russia and Myanmar to eastern China, Korea, Taiwan, Japan and northern Indochina. It is also a common symbol of the Korean identity, and has been adopted as the "official bird" of numerous South Korean cities, counties and provinces. Other names for the Oriental magpie include Korean magpie and Asian magpie.

In Korea, the magpie (까치, "kkachi") is celebrated as "a bird of great good fortune, of sturdy spirit and a provider of prosperity and development". In the same vein of bringing fortune and luck, Korean children were also taught that when you lose a tooth, to throw it on the roof singing a song for the magpie; 까치야 까치야 헌이 줄게. The bird will hear your song and bring you a new tooth.

Similarly, in China, magpies are seen as an omen of good fortune. This is reflected in the Chinese word for magpie, simplified Chinese: 喜鹊; traditional Chinese: 喜鵲; pinyin: xǐquè, in which the first character means "happiness". It was the official ‘bird of joy’ for the Manchu dynasty.

In Japan, it is found in all the main islands except Shikoku. It is called Kasasagi 鵲, the same name as is used for the Eurasian magpie (Pica pica ).

Compared to the Eurasian magpie, it is somewhat stockier, with a proportionally shorter tail and longer wings. The back, tail, and particularly the remiges show strong purplish-blue iridescence with few if any green hues. They are the largest magpies. They have a rump plumage that is mostly black, with but a few and often hidden traces of the white band which connects the white shoulder patches in their relatives.The Oriental magpie has the same call as the Eurasian magpie, albeit much softer.

28-11-2016 JURONG, SINGAPORE - MAGPIE GOOSE (Anseranas semipalmata)

The magpie goose (Anseranas semipalmata ) is the sole living representative species of the family Anseranatidae. This common waterbird is found in northern Australia and southern New Guinea. As the species is prone to wandering, especially when not breeding, it is sometimes recorded outside its core range. The species was once also widespread in southern Australia, but disappeared from there largely due to the drainage of the wetlands where the birds once bred. Due to their importance to Aboriginal people as a seasonal food source, as subjects of recreational hunting, and as a tourist attraction, their expansive and stable presence in northern Australia has been "ensured protective management".

Magpie geese are unmistakable birds with their black and white plumage and yellowish legs. The feet are only partially webbed, and the magpie goose feeds on vegetable matter in the water, as well as on land. Males are larger than females. Unlike true geese, their moult is gradual, so no flightless periods result. Their voice is a loud honking.

The magpie goose is found in a variety of open wetland areas such as floodplains and swamps, where they wade and swim. They eat mostly vegetation such as dry grass blades, grass seeds, spike rush bulbs and wild rice.

It is fairly sedentary apart from some movement during the dry season. They are colonial breeders and are gregarious outside of the breeding season when they can form large and noisy flocks of up to a few thousand individuals. Its nest is on the ground (also in trees 5 m or more high), and a typical clutch is 5-14 eggs. Some males mate with two females, all of which raise the young, unlike some other polygamous birds. This may be beneficial when predation of young is high as chicks raised by trios are more likely to survive.

This species is plentiful across its range, although this is significantly reduced in comparison to the range at time of European settlement. The range once extended as far south as the Coorong and the wetlands of the southeast of South Australia and Western Victoria. For Australia as a whole, it is not threatened and has a controlled hunting season when numbers are large. However, most of the southern populations were extirpated in the mid-20th century by overhunting and habitat destruction. The species has been subject to reintroduction projects such as Bool Lagoon between Penola and Naracoorte. Populations in more northern areas have again reached a level where it can be regularly utilized by hunters, although not in the example provided. The magpie goose was listed as near threatened on the 2007 advisory list of threatened vertebrate fauna in Victoria. In the December 2007 Flora and Fauna Guarantee Act list of threatened fauna, it is also listed. As of early 2008, an Action Statement for the recovery and future management of this species had not been prepared.

With the advent of climate change, and more frequent seawater inundations of the current extensive freshwater floodplains, CSIRO scientists argue that magpie geese populations may be at risk.

10-12-2016 MONTE CORONA, ADOR - EUROPEAN ROBIN (Erithacus rubecula)

The European robin (Erithacus rubecula) is a small insectivorous passerine bird. The term robin is also applied to some birds in other families with red or orange breasts. These include the American robin (Turdus migratorius ), a thrush, and the Australasian robins of the family Petroicidae.

The male and female European robins are similar in coloration, with an orange breast and face lined with grey, brown upperparts, and a whitish belly. The bill and eyes are black. Juveniles are spotted brown and white in coloration, with patches of orange gradually appearing.

European robins occur in Eurasia east to Western Siberia, south to Algeria, and on the Atlantic islands as far west as the Central Group of the Azores and Madeira. Irish and British robins are largely resident but a small minority, usually female, migrate to southern Europe during winter, a few as far as Spain. Scandinavian and Russian robins migrate to Britain and western Europe to escape the harsher winters. European robins prefer spruce woods in northern Europe, contrasting with their preference for parks and gardens in Ireland and Great Britain. These may also be found in grasslands, shrubby vegetation, hedgerows with some tall trees, orchards, and farmlands.

10-12-2016 ALBUFERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

The Great cormorant (Phalacrocorax carbo) is a widespread member of the cormorant family of seabirds. Many fishermen see in the Great cormorant a competitor for fish. Because of this, it was hunted nearly to extinction in the past but luckily due to conservation efforts, its numbers increased.

The Great cormorant is a large black bird, but there is a wide variation in size in the species' wide range. Males are typically larger and heavier than females. It has a longish tail and yellow throat patch. Adults have white patches on the thighs and on the throat in the breeding season. In European waters, the Great cormorant can be distinguished from the Common shag by its larger size, heavier build, thicker bill, lack of a crest, and plumage without any green tinge. In eastern North America, it is similarly larger and bulkier than the Double-crested cormorant, and the latter species has more yellow on the throat and bill and lack the white thigh patches frequently seen on great cormorants.

Great cormorants occur throughout Europe, Asia, Australia, Africa, and northeastern coastal North America. They may be both resident and migratory. Throughout the year in some areas, large groups remain within the breeding range. Greta cormorants frequent open marine environments and inland waters. They inhabit sandy or rocky sheltered coasts and estuaries and are rarely seen any distance from the coast. This species breeds on cliffs and inshore islands, among boulders and man-made structures. Birds that nest inland will breed on trees, bushes, and reedbeds, and even on bare ground.

Great cormorants are active during the day and are social birds, usually leaving roosts to forage early in the morning and returning within an hour. Little time each day is spent foraging, although parents with young tend to forage for longer. Much of the day is spent resting and preening near foraging areas or at roosts. Great cormorants generally are not aggressive towards one another, apart from at nest sites, where they exhibit territorial behavior. There may be dominance hierarchies. Outside of the breeding season, they usually gather in mixed-age, mixed-sex groups.

10-12-2016 ALBUFERA, VALENCIA - GREAT EGRET (Ardea alba)

The Great egret (Ardea alba) is a large, widely distributed wading bird. Like all egrets, it is a member of the heron family, Ardeidae, and its close relatieves are pelicans. The Great egret is sometimes confused with the Great white heron of the Caribbean, which is a white morph of the closely related Great blue heron.

This elegant heron is completely white with its magnificent plumage, reminding lace. The bill of the Great egret is sharp, long and yellow in color. The bird has long, black feet and legs. During the breeding season, the bill becomes a bit darker while the legs get lighter. This bird possesses a very long neck, exceeding the length of its body. The bird has a notable kink of its neck, curving the necks into a "S" shape when flying. Male and female egrets generally look similar, though females are a bit smaller than males. Young egrets usually look like non-breeding adults. During the breeding season, these birds grow long, lacy shaped feathers known as "aigrettes”, stretching them in an impressive display.

These birds are widely distributed throughout the world including North and South Americas, Eurasia, Africa, and Australia. In Africa, they can be found only outside the breeding season. Great egrets prefer living near any water body, occurring along streams, lakes, in saltwater and freshwater marshes, muddy areas, and ponds. Just like other heron species, these birds are most frequently found in wetlands and wooded swamps.

Great egrets are diurnal feeders. They can feed both in flocks of their own kind and these of other heron species. At sunset, egrets of surrounding areas usually come together, roosting in colonies. They feed in shallow water, walking slowly and looking for prey. And when the prey is spotted, they abruptly thrust the bill into the water, catching it. They will also steal a great part of their food from smaller heron species. After breeding, these birds usually disperse. Egrets, living in mild climates, remain in their breeding areas throughout the winter while those, breeding in northern regions where water freezes during the winter, have to migrate. As with many bird species, Great egrets become rather aggressive when it comes to feeding, even if there's an abundance of food. Occasionally, even parents can fight for food with their young.

10-12-2016 ALBUFERA, VALENCIA - HOUSE SPARROW (FEMALE) (Passer domesticus)

The house sparrow (Passer domesticus) is a bird of the sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of 16 cm (6.3 in) and a mass of 24–39.5 g (0.85–1.39 oz). Females and young birds are coloured pale brown and grey, and males have brighter black, white, and brown markings. One of about 25 species in the genus Passer, the house sparrow is native to most of Europe, the Mediterranean Basin, and a large part of Asia. Its intentional or accidental introductions to many regions, including parts of Australasia, Africa, and the Americas, make it the most widely distributed wild bird.

The house sparrow is strongly associated with human habitation, and can live in urban or rural settings. Though found in widely varied habitats and climates, it typically avoids extensive woodlands, grasslands, polar regions, and hot, dry deserts far away from human development. For sustenance, the house sparrow routinely feeds at home and public bird feeding stations, but naturally feeds on the seeds of grains, flowering plants and weeds. However, it is an opportunistic, omnivorous eater, and commonly catches insects, their larvae, caterpillars, invertebrates and many other natural foods.

10-12-2016 ALBUFERA, VALENCIA - ODOROUS ANTS (Subfamily Dolichoderinae)

Dolichoderinae is a subfamily of ants, which includes species such as the Argentine ant (Linepithema humile), the erratic ant, the odorous house ant, and the cone ant. The subfamily presents a great diversity of species throughout the world, distributed in different biogeographic realms, from the Palearctic, Nearctic, Afrotropical region and Malaysia, to the Middle East, Australian, and Neotropical regions.

This subfamily is distinguished by having a single petiole (no post-petiole) and a slit-like orifice, from which chemical compounds are released. Dolichoderine ants do not possess a sting, unlike ants in some other subfamilies, such as Ponerinae and Myrmicinae, instead relying on the chemical defensive compounds produced from the anal gland.

Of the compounds produced by dolichoderine ants, several terpenoids were identified including the previously unknown iridomyrmecin, isoiridomyrmecin, and iridodial. Such compounds are responsible for the smell given off by ants of this subfamily when crushed or disturbed.

10-12-2016 ALBUFERA, VALENCIA - GREY HERON (Ardea cinerea)

The Grey heron (Ardea cinerea) is a large long-legged wading bird of the heron native to Europe and Asia and also parts of Africa. It lives in wetland areas and feeds on various aquatic creatures which it catches after standing stationary beside or in the water.

The plumage of the Grey heron is largely ashy-grey above, and greyish-white below with some black on the flanks. Adults have a head and neck white with a broad black supercilium that terminates in the slender, dangling crest, and bluish-black streaks on the front of the neck. The scapular feathers are elongated and the feathers at the base of the neck are also somewhat elongated. Immature birds lack the dark stripe on the head and are generally duller in appearance than adults, with a grey head and neck, and a small, dark grey crest. The pinkish-yellow beak is long, straight, and powerful, and is brighter in color in breeding adults. The iris is yellow and the legs are brown and very long.

Grey herons occur in most parts of Europe, Asia, and Africa. Over much of their range, these birds are resident, but populations from the more northerly parts of Europe migrate southwards; some remain in Central and Southern Europe, and others travel on to Africa south of the Sahara Desert. Grey herons can be found anywhere with suitable watery habitats that can supply their food. Although most common in the lowlands, they also occur in mountain tarns, lakes, reservoirs, large and small rivers, marshes, ponds, ditches, flooded areas, coastal lagoons, estuaries, and seashore. They sometimes forage away from water in the pasture, and can even be found in desert areas, hunting for beetles and lizards. 

10-12-2016 ALBUFERA, VALENCIA - EUROPEAN STARLING (Sturnus vulgaris)

The Common starling (Sturnus vulgaris) is a medium-sized passerine bird in the starling family, Sturnidae. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.

The Сommon starling is a medium-sized bird. It has glossy black plumage with a metallic sheen, which is speckled with white at some times of the year. The legs are pink and the bill is black in winter and yellow in summer. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the color of the irises, rich brown in males, mouse-brown, or grey in females.

Common starlings are native to Eurasia and are found throughout Europe, northern Africa (from Morocco to Egypt), India (mainly in the north but regularly extending further south and extending into the Maldives) Nepal, the Middle East including Syria, Iran, and Iraq and north-western China. Common starlings in the south and west of Europe are mainly resident, although other populations migrate from regions where the winter is harsh. Most birds from northern Europe, Russia, and Ukraine migrate southwestwards or southeastwards. In the autumn, when immigrants are arriving from eastern Europe, many of Britain's common starlings are setting off for Iberia and North Africa. Common starlings prefer urban or suburban areas, reedbeds, grassy areas such as farmland, grazing pastures, playing fields, golf courses, and airfields where short grass makes foraging easy. They occasionally inhabit open forests and woodlands and are sometimes found in shrubby areas. These birds are also found in coastal areas, where they nest and roost on cliffs and forage amongst the seaweed.

10-12-2016 ALBUFERA, VALENCIA - BLACK HEADED GULL (Chroicocephalus ridibundus)

The black-headed gull (Chroicocephalus ridibundus) is a small gull that breeds in much of the Palearctic including Europe and also in coastal eastern Canada. Most of the population is migratory and winters further south, but some birds reside in the milder westernmost areas of Europe. The species also occurs in smaller numbers in northeastern North America, where it was formerly known as the common black-headed gull.

The black-headed gull was previously placed in the genus Larus but in agreement with the NACC and SACC, and based on Pons et al. (Pons, J.-M.., A. Hassanin, and P.-A. Crochet. 2005. "Phylogenetic relationships within the Laridae" (Charadriiformes: Aves) inferred from mitochondrial markers, "Molecular Phylogenetics and Evolution" 37: 686-699) and earlier references, extensive changes to the taxonomy of gulls was undertaken and many species of gull were removed from the genus Larus, including the black-headed gull 

The black-headed gull displays a variety of compelling behaviours and adaptations. Some of these include removing eggshells from the nest after hatching, begging co-ordination between siblings, differences between sexes, conspecific brood parasitism, and extra-pair paternity. They are an overwintering species, found in a variety of different habitats.

This gull is 37–44 cm (14+1⁄2–17+1⁄2 in) long with a 94–110 cm (37–43+1⁄2 in) wingspan and weighs 190–400 g (6+3⁄4–14+1⁄8 oz).

In flight, the white leading edge to the wing is a good field mark. The summer adult has a chocolate-brown head (not black, although does look black from a distance), pale grey body, black tips to the primary wing feathers, and red bill and legs. The hood is lost in winter, leaving just two dark spots. Immature birds have a mottled pattern of brown spots over most of the body, and a black band on the tail. There is no difference in plumage between the sexes.

It breeds in colonies in large reed beds or marshes, or on islands in lakes, nesting on the ground. Like most gulls, it is highly gregarious in winter, both when feeding or in evening roosts. It is not a pelagic species and is rarely seen at sea far from coasts.

The black-headed gull is a bold and opportunistic feeder. It eats insects, fish, seeds, worms, scraps, and carrion in towns, or invertebrates in ploughed fields with equal relish. It is a noisy species, especially in colonies, with a familiar "kree-ar" call. Its scientific name means laughing gull.

This species takes two years to reach maturity. First-year birds have a black terminal tail band, more dark areas in the wings, and, in summer, a less fully developed dark hood. Like most gulls, black-headed gulls are long-lived birds, with a maximum age of at least 32.9 years recorded in the wild, in addition to an anecdote now believed of dubious authenticity regarding a 63-year-old bird.

Black-headed gulls can be found over much of Europe. It is also found in across the Palearctic to Japan and east China. Small numbers also breed in northeastern Canada and can be seen in winter in northeast North America as far south as Virginia, often with the similar-looking Bonaparte's Gull and also in some Caribbean islands. Recorded as a very rare transient gull in the Carolina coast. 

10-12-2016 ALBUFERA, VALENCIA - EURASIAN GREAT CORMORANT (Phalacrocorax carbo)

Great cormorants are monogamous, with pairs sometimes reuniting in subsequent years. The male chooses the nest site, displaying to attract the female by waving his wings up and down and flashing his white rump patch. He will also swing his head from side to side while holding his tail erect and calling loudly. The female responds by swinging her head slightly and “purring”. This species breeds at any time, depending on food resources. Breeding takes place in colonies of as many as 2,000 pairs, although colonies of a smaller size are typical. Colonies are often located close to other species, like darters, herons, and spoonbills. The parents build their nest with reeds, sticks, and seaweeds on a cliff, in a tree, or in a bush, according to the region. Often a nest is reused. 2 to 6 eggs are laid, with an average of 3-4. The parents share the incubation for 27 to 31 days. The altricial chicks hatch at intervals and fledge at about 50 days old. They remain with their parents for 50 or more days, relying on them for food. The young start to breed between 2 and 4 years old, typically when 3 years old.

Great cormorants have large populations and are widespread, although surveys are not complete across their range. Being an important fish competitor, in the past, they were almost extinct in Europe. However, in recent years increases have been observed, thanks to intensive protection. But in some countries, expanding conflicts with fish farms and fisheries lead to new persecution. Another threat is that hatchlings may be eaten by raptors before fledging.

Population number

The IUCN Red List reports that the global population of Great cormorants is about 1,400,000-2,100,000 individuals. The European population is estimated at 401,000-512,000 pairs, which equates to 803,000-1,020,000 mature individuals. Overall, currently, Great cormorants are classified as Least Concern (LC) on the IUCN Red List and their numbers today are increasing.

10-12-2016 ALBUFERA, VALENCIA - WESTERN CATTLE EGRET (Bubulcus ibis ssp. ibis)

The Cattle egret (Bubulcus ibis) is a cosmopolitan species of heron named for its association with cattle. It is the only member of the monotypic genus Bubulcus, although some authorities regard its two subspecies as full species, the Western cattle egret and the Eastern cattle egret. Despite the similarities in plumage to the egrets of the genus Egretta, it is more closely related to the herons of Ardea.

The Cattle egret is a stocky bird. It has a relatively short, thick neck, a sturdy bill, and a hunched posture. The nonbreeding adult has mainly white plumage, a yellow bill, and greyish-yellow legs. During the breeding season, adults of the nominate western subspecies develop orange-buff plumes on the back, breast, and crown, and the bill, legs, and irises become bright red for a brief period prior to pairing. The sexes are similar, but the male is marginally larger and has slightly longer breeding plumes than the female; juvenile birds lack coloured plumes and have a black bill.

Cattle egrets are native to parts of Asia, Africa, and Europe but they have undergone a rapid expansion in their distribution and successfully colonized much of the rest of the world in the last century. Many populations of Cattle egrets are highly migratory, while others are dispersive, and distinguishing between the two can be difficult. In many areas, populations can be both sedentary and migratory. In the Northern Hemisphere, migration is from cooler climes to warmer areas, but Cattle egrets nesting in Australia migrate to cooler Tasmania and New Zealand in the winter and return in the spring. Migration in western Africa is in response to rainfall, and in South America, migrating birds travel south of their breeding range in the non-breeding season. Populations in southern India appear to show local migrations in response to the monsoons. Cattle egrets inhabit wetlands, dry grassy habitats, semi-arid steppes, floodplains, freshwater swamps, shallow marshes, and mangroves. They are often found in fields, croplands, and pastures with poor drainage. When nesting, Cattle egrets are found in woodlands near lakes or rivers, in swamps, or on small inland or coastal islands.

10-12-2016 ALBUFERA, VALENCIA - GLOSSY IBIS (Plegadis falcinellus)

Sometimes called the more cosmopolitan ibis, the Glossy Ibis, is the most widespread ibis species. It can be found in South, North and Central America, southern Europe, Africa, Asia, and Australia. In the US it primarily lives along the Atlantic coast but can also be found in a variety of inland wetlands.

bises have curved, slender bills that they use to probe into shallow water, mud or grass when foraging. Ibises are gregarious birds that live, travel and breed in flocks. In flight, they form diagonal lines or V-formations. This formation decreases wind resistance for trailing birds.

The glossy ibis is a heron-like bird with a long, curving beak. They breed in parts of southern and southeast Europe and are occasional visitors to the UK. However, in recent decades sightings here have become more common, mirroring an increase in their breeding population in southwest Europe.

Flocks of Glossy Ibises wade in the shallows of eastern marshes, probing for food with their sickle-shaped bills. Widespread in the Old World, the species is found in the New World mainly in the West Indies and along our Atlantic Coast, especially Florida, where it was quite scarce as recently as the 1930s. It may have invaded within the last few centuries, riding the trade winds across from West Africa to the Caribbean.

Withdraws from northern part of breeding range in winter. Migrates in flocks, moving south relatively early. Singles and small flocks sometimes wander far north and inland, especially in spring and summer.

Marshes, rice fields, swamps. Forages in shallow waters, favoring marshes (either fresh or salt), flooded fields, shallow ponds, estuaries. Nests in low stands of willows and other shrubs surrounded by marsh, on ground in spartina marsh, in dense thickets of trees and shrubs on higher ground, sometimes in mangroves.

28-11-2016 JURONG, SINGAPORE - SPOT BILLED PELICAN (Pelecanus philippensis)

The spot-billed pelican (Pelecanus philippensis ) or grey pelican is a member of the pelican family. It breeds in southern Asia from southern Iran across India east to Indonesia. It is a bird of large inland and coastal waters, especially large lakes. At a distance they are difficult to differentiate from other pelicans in the region although it is smaller but at close range the spots on the upper mandible, the lack of bright colours and the greyer plumage are distinctive. In some areas these birds nest in large colonies close to human habitations.

This species was once used by fishermen in parts of eastern Bengal as decoys for certain fish. These fishermen believed that an oily secretion from the bird attracted certain fish such as Colisa and Anabas.

The propensity of these birds to nest close to human habitations has been noted from the time of T C Jerdon:

Several colonies have since been discovered and while many of these have vanished others have been protected and a few villages with nesting colonies have become popular tourist attractions. Well known villages with colonies include Kokrebellur, Koothankulam and Uppalapadu.
