Gulls or seagulls are seabirds of the family Laridae in the suborder Lari. They are most closely related to the terns (family Sternidae) and only distantly related to auks, skimmers, and more distantly to the waders. Gulls are typically medium to large birds, usually grey or white, often with black markings on the head or wings. They typically have harsh wailing or squawking calls; stout, longish bills; and webbed feet. Most gulls are ground-nesting carnivores which take live food or scavenge opportunistically, particularly the Larus species. Live food often includes crabs and small fish. Gulls have unhinging jaws which allow them to consume large prey. Gulls are typically coastal or inland species, rarely venturing far out to sea, except for the kittiwakes. 25951

The scimitar oryx or scimitar-horned oryx (Oryx dammah), also known as the Sahara oryx, is a species of Oryx that was once widespread across North Africa. The species went extinct in the wild in 2000 but a group was released into an acclimation enclosure within the Ouadi Rimé-Ouadi Achim Faunal Reserve in 2016, then reintroduced back into the wild. 21 additional animals were placed in the acclimation enclosure in 2017. his antelope stands a little more than 1 metre at the shoulder. The males weigh 140–210 kg and the females weigh 91–140 kg. The coat is white with a red-brown chest and black markings on the forehead and down the length of the nose. The calves are born with a yellow coat without distinguishing marks; their coats change to adult coloration at 3–12 months old. The scimitar oryx was once widespread across northern Africa. Its decline began as a result of climate change during the neolithic period, and later it was hunted extensively for its horns. Today, it is bred in captivity in special reserves in Tunisia, Morocco and Senegal and on private exotic animal ranches in the Texas Hill Country. 26987

A cockatoo is any of the 21 parrot species belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea (true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia. Cockatoos are recognisable by the prominent crests and curved bills. Their plumage is generally less colourful than that of other parrots, being mainly white, grey or black and often with coloured features in the crest, cheeks or tail. On average they are larger than other parrots; however, the cockatiel, the smallest cockatoo species, is a small bird. Cockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly when ground-feeding. Cockatoos are monogamous and nest in tree hollows. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable nesting hollows after large mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests. 38003

Pelicans are a genus of large water birds that make up the family Pelecanidae. They are characterised by a long beak and a large throat pouch used for catching prey and draining water from the scooped-up contents before swallowing. They have predominantly pale plumage, the exceptions being the brown and Peruvian pelicans. The bills, pouches, and bare facial skin of all species become brightly coloured before the breeding season. The eight living pelican species have a patchy global distribution, ranging latitudinally from the tropics to the temperate zone, though they are absent from interior South America and from polar regions and the open ocean. Pelicans frequent inland and coastal waters, where they feed principally on fish, catching them at or near the water surface. They are gregarious birds, travelling in flocks, hunting cooperatively, and breeding colonially. Four white-plumaged species tend to nest on the ground, and four brown or grey-plumaged species nest mainly in trees. The relationship between pelicans and people has often been contentious. The birds have been persecuted because of their perceived competition with commercial and recreational fishing. Their populations have fallen through habitat destruction, disturbance, and environmental pollution, and three species are of conservation concern. They also have a long history of cultural significance in mythology, and in Christian and heraldic iconography. 61272

Bicentennial Park is a 40-hectare of parkland located 16 kilometres west of the Sydney central business district in the local government area of City of Parramatta. Bicentennial Park is situated on the shores Homebush Bay and is a part of the Sydney Olympic Park in New South Wales, Australia. The Park is a natural heritage site featuring an important wetland ecosystem and parklands. It offers visitors recreation, nature-based tours, environmental education and outdoor event experiences. The park has picnic areas, playgrounds, pathways and cycle ways, access to the wetlands, salt marsh and bird hides. It also features Lake Belvedere, Peace Monument, Treillage Tower, Sundial, 'Cyrus the Great' statue, the Silent Hearts Memorial Garden and water features. Powells Creek runs through the eastern side of the park. The Homebush Bay wetland is occupied by animals that thrive in the salt water wetlands. Bicentennial Park was created by the state and federal governments during the 1980s, to celebrate Australia's Bicentenary in 1988. The project involved recycling 47.4 hectares of former rubbish dump into a regional recreation area and the conservation of 53 hectares of a wetland ecosystem on the Parramatta River. The park was officially opened on 1 January 1988. 46007

The goldfish (Carassius auratus) is a freshwater fish in the family Cyprinidae of order Cypriniformes. It is one of the most commonly kept aquarium fish. A relatively small member of the carp family (which also includes the Prussian carp and the crucian carp), the goldfish is native to East Asia. It was first selectively bred in ancient China more than 1,000 years ago, and several distinct breeds have since been developed. Goldfish breeds vary greatly in size, body shape, fin configuration and coloration (various combinations of white, yellow, orange, red, brown, and black are known). Goldfish have strong associative learning abilities, as well as social learning skills. Goldfish are gregarious, displaying schooling behavior, as well as displaying the same types of feeding behaviors. 36387

Rhina ancylostoma, the bowmouth guitarfish, shark ray or mud skate, is a species of ray and a member of the family Rhinidae. Its evolutionary affinities are not fully resolved, though it may be related to true guitarfishes and skates. This rare species occurs widely in the tropical coastal waters of the western Indo-Pacific, at depths of up to 90 m (300 ft). Highly distinctive in appearance, Rhina ancylostoma has a wide and thick body with a rounded snout and large shark-like dorsal and tail fins. Its mouth forms a W-shaped undulating line, and there are multiple thorny ridges over its head and back. It has a dorsal color pattern of many white spots over a bluish gray to brown background, with a pair of prominent black markings over the pectoral fins. This large species can reach a length of 2.7 m (8.9 ft) and weight of 135 kg (298 lb). Usually found near the sea floor, Rhina ancylostoma prefers sandy or muddy areas near underwater structures. It is a strong-swimming predator of bony fishes, crustaceans, and molluscs. 24694

The Australian magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus and is most closely related to the black butcherbird (Melloria quoyi). Currawongs have yellow eyes, whereas Magpies have red-brown eyes and Butcherbirds have very dark brown, almost black eyes. It is not, however, closely related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from 37 to 43 cm in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground. Described as one of Australia's most accomplished songbirds, the Australian magpie has an array of complex vocalisations. It is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. This species is commonly fed by households around the country, but in spring (and occasionally in autumn) a small minority of breeding magpies (almost always males) become aggressive and swoop and attack those who approach their nests.

Licmetis is a subgenus of the white cockatoos (genus Cacatua). They are collectively known as corellas in Australia. Three of the six species are primarily – or only – found in Australia, while the Philippines, Indonesia, and the Solomons each have an endemic species. They are relatively small cockatoos and – unlike the members of the subgenus Cacatua – all have pale bills. While most show yellow-tinged underwings and some red to the face, none has conspicuously coloured crests. R_707

A rhinoceros, from Greek rhinokerōs, meaning 'nose-horned', from rhis, meaning 'nose', and keras, meaning 'horn'), commonly abbreviated to rhino, is one of any five extant species of odd-toed ungulates in the family Rhinocerotidae, as well as any of the numerous extinct species therein. Two of the extant species are native to Africa, and three to Southern Asia. The term rhinoceros is often more broadly applied to now extinct species of the superfamily Rhinocerotoidea. Members of the rhinoceros family are some of the largest remaining megafauna, with all species able to reach or exceed one tonne in weight. They have a herbivorous diet, small brains (400–600 g) for mammals of their size, one or two horns, and a thick (1.5–5 cm) protective skin formed from layers of collagen positioned in a lattice structure. They generally eat leafy material, although their ability to ferment food in their hindgut allows them to subsist on more fibrous plant matter when necessary. Unlike other perissodactyls, the two African species of rhinoceros lack teeth at the front of their mouths, relying instead on their lips to pluck food. 26669

Ibises are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains. Ibises usually feed as a group, probing mud for food items, usually crustaceans. It is widespread across much of Australia. It has a predominantly white plumage with a bare, black head, long down curved bill and black legs. They are monogamous and highly territorial while nesting and feeding. Most nest in trees, often with spoonbills or herons. Due to its increasing presence in the urban environment and its habit of rummaging in garbage, the species has acquired a variety of colloquial names such as tip turkey; and bin chicken, and in recent years has become an icon of popular culture, being regarded with passion, wit, and, in equal measure, affection and disgust. 49054

The willie (or willy) wagtail (Rhipidura leucophrys) is a passerine bird native to Australia, New Guinea, the Solomon Islands, the Bismarck Archipelago, and Eastern Indonesia. It is a common and familiar bird throughout much of its range, living in most habitats apart from thick forest. Measuring 19–21.5 cm in length, the willie wagtail is contrastingly coloured with almost entirely black upperparts and white underparts; the male and female have similar plumage. Three subspecies are recognised; Rhipidura leucophrys leucophrys from central and southern Australia, the smaller R. l. picata from northern Australia, and the larger R. l. melaleuca from New Guinea and islands in its vicinity. It is unrelated to the true wagtails of the genus Motacilla; it is a member of the fantail genus Rhipidura and is a part of a core corvine group that includes true crows and ravens, drongos and birds of paradise. Within this group, fantails are placed either in the family Dicruridae, alongside drongos, or in their own small family, Rhipiduridae. The willie wagtail is insectivorous and spends much time chasing prey in open habitat. Its common name is derived from its habit of wagging its tail horizontally when foraging on the ground. Aggressive and territorial, the willie wagtail will often harass much larger birds such as the laughing kookaburra and wedge-tailed eagle. It has responded well to human alteration of the landscape and is a common sight in urban lawns, parks, and gardens. It was widely featured in Aboriginal folklore around the country as either a bringer of bad news or a stealer of secrets. 23183

Egrets (/ˈiːɡrəts/ EE-grəts) are herons, generally long-legged wading birds, that have white or buff plumage, developing fine plumes (usually milky white) during the breeding season. Egrets are not a biologically distinct group from herons and have the same build.

Many egrets are members of the genera Egretta or Ardea, which also contain other species named as herons rather than egrets. The distinction between a heron and an egret is rather vague, and depends more on appearance than biology. The word "egret" comes from the French word aigrette that means both "silver heron" and "brush", referring to the long, filamentous feathers that seem to cascade down an egret's back during the breeding season (also called "egrets").

Several of the egrets have been reclassified from one genus to another in recent years; the great egret, for example, has been classified as a member of either Casmerodius, Egretta, or Ardea.

In the 19th and early part of the 20th centuries, some of the world's egret species were endangered by relentless plume hunting, since hat makers in Europe and the United States demanded large numbers of egret plumes, leading to breeding birds being killed in many places around the world. 62079

Kookaburras are terrestrial tree kingfishers of the genus Dacelo native to Australia and New Guinea, which grow to between 28–42 cm in length. The name is a loanword from Wiradjuri guuguubarra, onomatopoeic of its call. The loud distinctive call of the laughing kookaburra is widely used as a stock sound effect in situations that involve an Australian bush setting or tropical jungle, especially in older movies. They are found in habitats ranging from humid forest to arid savanna, as well as in suburban areas with tall trees or near running water. Even though they belong to the larger group known as 'kingfishers', kookaburras are not closely associated with water. Kookaburras are almost exclusively carnivorous, eating mice, snakes, insects, small reptiles, and the young of other birds; unlike many other kingfishers, they rarely eat fish, although they have been known to take goldfish from garden ponds. In zoos they are usually fed food for birds of prey. 18791

A poppy is a flowering plant in the subfamily Papaveroideae of the family Papaveraceae. Poppies are herbaceous plants, often grown for their colourful flowers. One species of poppy, Papaver somniferum, is the source of the narcotic drug opium which contains powerful medicinal alkaloids such as morphine and has been used since ancient times as an analgesic and narcotic medicinal and recreational drug. It also produces edible seeds. Following the trench warfare in the poppy fields of Flanders, Belgium during World War I, poppies have become a symbol of remembrance of soldiers who have died during wartime. Poppies are herbaceous annual, biennial or short-lived perennial plants. Some species are monocarpic, dying after flowering. Poppies can be over a metre tall with flowers up to 15 centimetres across. Flowers of species (not cultivars) have 4 to 6 petals, many stamens forming a conspicuous whorl in the center of the flower and an ovary of from 2 to many fused carpels. The petals are showy, may be of almost any color and some have markings. 4281

Rainbow lorikeets are true parrots, within the Psittacoidea superfamily in the order Psittaciformes. The rainbow lorikeet or lorikeet (common name) is a species of parrot found in Australia. It is common along the eastern seaboard, from northern Queensland to South Australia. Its habitat is rainforest, coastal bush and woodland areas. They are true parrots of medium-size, with the length ranging from 25 to 30 cm, including the tail. The weight varies from 75 to 157 g. The plumage of the nominate race, as with all subspecies, is very bright. The 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. 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. 38306

Papilio aegeus, the orchard swallowtail butterfly or large citrus butterfly is a species of butterfly from the family Papilionidae, that is found in eastern Australia and Papua New Guinea. The larvae of this species are sometimes considered a pest, due to their feeding on citrus leaves in suburban gardens. Both male and female have black forewings with a white stripe, though there is more white overall on the female forewing. The hindwing is again black, and there is a white swath through the middle. Here the markings differ in that the female has chains of red to orange and blue crescents toward the edge. The markings on the underside are similar to those on top. The body is black. The wingspan is about 140 millimetres in females and 120 millimetres in males, making it rather large overall and the largest butterfly commonly seen in at least part of its range. Despite being a swallowtail, which group derives its name from the distinctive tails on the hindwing, this characteristic is entirely absent. 6403.

They are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. Butterflies have the typical four-stage insect life cycle. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take several years to pass through their entire life cycle. Butterflies are often polymorphic, and many species make use of camouflage, mimicry and aposematism to evade their predators. Some, like the monarch and the painted lady, migrate over long distances. Many butterflies are attacked by parasites or parasitoids, including wasps, protozoans, flies, and other invertebrates, or are preyed upon by other organisms. 22423

Spoonbills are a genus, Platalea, of large, long-legged wading birds. The spoonbills have a global distribution, being found on every continent except Antarctica. The genus name Platalea derives from Latin and means broad, referring to the distinctive shape of the bill. Six species are recognised, which although usually placed in a single genus have sometimes been split into three genera. All spoonbills have large, flat, spatulate bills and feed by wading through shallow water, sweeping the partly opened bill from side to side. The moment any small aquatic creature touches the inside of the bill—an insect, crustacean, or tiny fish—it is snapped shut. Spoonbills generally prefer fresh water to salt but are found in both environments. They need to feed many hours each day. The spoonbills are most distinct from the ibises in the shape of their bill, which is long and flat and wider at the end. The nostrils are located near the base of the bill so that the bird can breathe while the bill is submerged in water. The eyes are positioned to provide spoonbills with binocular vision, although when foraging tactile senses are important too. Like the ibises the spoonbills have bare patches of skin around the bills and eyes. The six species of spoonbill are distributed over much of the world.

Ibises are a group of long-legged wading birds in the family Threskiornithidae, that inhabit wetlands, forests and plains. Ibises usually feed as a group, probing mud for food items, usually crustaceans. It is widespread across much of Australia. It has a predominantly white plumage with a bare, black head, long down curved bill and black legs. They are monogamous and highly territorial while nesting and feeding. Most nest in trees, often with spoonbills or herons. Due to its increasing presence in the urban environment and its habit of rummaging in garbage, the species has acquired a variety of colloquial names such as tip turkey; and bin chicken, and in recent years has become an icon of popular culture, being regarded with passion, wit, and, in equal measure, affection and disgust. 49002

The emu (Dromaius novaehollandiae) is the second-largest living bird by height, after its ratite relative, the ostrich. It is endemic to Australia where it is the largest native bird and the only extant member of the genus Dromaius. The emu's range covers most of mainland Australia, but the Tasmanian, Kangaroo Island and King Island subspecies became extinct after the European settlement of Australia in 1788. The bird is sufficiently common for it to be rated as a least-concern species. Emus are soft-feathered, brown, flightless birds with long necks and legs, and can reach up to 1.9 metres in height. Emus can travel great distances, and when necessary can sprint at 50 km/h; they forage for a variety of plants and insects, but have been known to go for weeks without eating. They drink infrequently, but take in copious amounts of water when the opportunity arises. The emu is an important cultural icon of Australia, appearing on the coat of arms and various coins. The bird features prominently in Indigenous Australian mythology. 17400

The masked lapwing (Vanellus miles), also known as the masked plover and often called the spur-winged plover or just plover in its native range, is a large, common and conspicuous bird native to Australia, particularly the northern and eastern parts of the continent, New Zealand and New Guinea. It spends most of its time on the ground searching for food such as insects and worms and has several distinctive calls. There are two subspecies; the southern novaehollandiae has distinctive black markings on the shoulder and side of the chest, and is sometimes recognized as a separate species, the black-shouldered lapwing (Vanellus novaehollandiae). These brown-black, white and yellow plovers are common in Australian fields and open land. The masked lapwing is the largest representative of the family Charadriidae. It measures from 30 to 37 cm in length and has a wingspan of 75–85 cm. The nominate subspecies (V. m. miles) weighs 191–300 g, while the southern race (V. m. novaehollandiae) is larger and weighs 296–412 g. The birds have a wide range of calls which can be heard at any time of the day or night: the warning call, a loud defending call, courtship calls, calls to its young, and others. Since this bird lives on the ground it is always alert and even though it rests it never sleeps properly. Masked lapwings are most common around the edges of wetlands and in other moist, open environments, but are adaptable and can often be found in surprisingly arid areas. They can also be found on beaches and coastlines. 41910

Phonognatha graeffei, referred to as the leaf curling spider, is a common Australian spider found in woodlands and urban areas in the northeastern, eastern and southern states. A small member of the family Araneidae, the orb-weavers, it was previously placed in Tetragnathidae. The spider is distinguished by having a curled leaf at the centre of its web, in which it shelters. The species form pairs living together in the same leaf, though at opposite ends of their shelter, even before mating at maturity. The female creates a separate curled leaf "nursery" hung in foliage nearby. The body length of the male is 5 to 6mm and female 8 to 12mm. Males and females look very similar with red-brown legs and body and a cream coloured pattern on their backs. Their bodies are fat and oval shaped with long tapered legs. The web, with its shelter at the centre, is easily identifiable. The leaf curling spider cleverly weaves a leaf or other object into the centre of its web as a hide-away from birds and other predators. Leaves are twisted along their length to form a funnel, (sometimes with a silk wall on one side, if necessary) that the spider can retreat into. They have also been known to use old snail shells and discarded pieces of paper. Although often found clustered in the same area, each spider has its own web. The leaf curling spider's web is about 30 cm in diameter. It is an incomplete circle, being open at the top and fanning downwards. The spider uses supporting threads attached to a shrub to suspend its curled-up dry leaf, with the fan-like main web radiating out from the leaf in which the spider hides, with only the tips of its legs visible, feeling for the vibrations of insects colliding with the web. It only goes outside its shelter if prey becomes stuck in the web, or if the web need repair. The spider usually rebuilds its web at night. The leaf-curling spiders are day-active orb weavers, protecting themselves from predators by sitting inside their silk-seamed, curled leaf. In P. graeffei this leaf is suspended just above the centre of the web, but may be placed higher in other species. Such leaves may be already part curled though many are not, and the spider pulls and silks its leaf into a retreat cylinder, silked shut at the top and open at the hub. Like other web-weaving spiders, their main food source is flying insects including insects larger than itself. They are noted for their sexual cohabitation and its function in mate-guarding behaviour. This means that the male and female live together in the same curled leaf, occupying opposite ends of the retreat, with the female at the open end. 20150

Bicentennial Park is a 40-hectare of parkland located 16 kilometres west of the Sydney central business district in the local government area of City of Parramatta. Bicentennial Park is situated on the shores Homebush Bay and is a part of the Sydney Olympic Park in New South Wales, Australia. The Park is a natural heritage site featuring an important wetland ecosystem and parklands. It offers visitors recreation, nature-based tours, environmental education and outdoor event experiences. The park has picnic areas, playgrounds, pathways and cycle ways, access to the wetlands, salt marsh and bird hides. It also features Lake Belvedere, Peace Monument, Treillage Tower, Sundial, 'Cyrus the Great' statue, the Silent Hearts Memorial Garden and water features. Powells Creek runs through the eastern side of the park. The Homebush Bay wetland is occupied by animals that thrive in the salt water wetlands. Bicentennial Park was created by the state and federal governments during the 1980s, to celebrate Australia's Bicentenary in 1988. The project involved recycling 47.4 hectares of former rubbish dump into a regional recreation area and the conservation of 53 hectares of a wetland ecosystem on the Parramatta River. The park was officially opened on 1 January 1988. 25162

A cockatoo is any of the 21 parrot species belonging to the family Cacatuidae, the only family in the superfamily Cacatuoidea. Along with the Psittacoidea (true parrots) and the Strigopoidea (large New Zealand parrots), they make up the order Psittaciformes. The family has a mainly Australasian distribution, ranging from the Philippines and the eastern Indonesian islands of Wallacea to New Guinea, the Solomon Islands and Australia. Cockatoos are recognisable by the prominent crests and curved bills. Their plumage is generally less colourful than that of other parrots, being mainly white, grey or black and often with coloured features in the crest, cheeks or tail. On average they are larger than other parrots; however, the cockatiel, the smallest cockatoo species, is a small bird. Cockatoos prefer to eat seeds, tubers, corms, fruit, flowers and insects. They often feed in large flocks, particularly when ground-feeding. Cockatoos are monogamous and nest in tree hollows. Some cockatoo species have been adversely affected by habitat loss, particularly from a shortage of suitable nesting hollows after large mature trees are cleared; conversely, some species have adapted well to human changes and are considered agricultural pests.

Koi or more specifically jinli or nishikigoi are colored varieties of the Amur carp (Cyprinus rubrofuscus) that are kept for decorative purposes in outdoor koi ponds or water gardens. Koi is an informal group name of the colored variants of C. rubrofuscus. Several varieties are recognized by the Japanese. Koi varieties are distinguished by coloration, patterning, and scalation. Some of the major colors are white, black, red, orange, yellow, blue, and cream. The most popular category of koi is the Gosanke, which is made up of the Kohaku, Taisho Sanshoku, and Showa Sanshoku varieties.

The Pacific black duck (Anas superciliosa), commonly known as the PBD, is a dabbling duck found in much of Indonesia, New Guinea, Australia, New Zealand, and many islands in the southwestern Pacific, reaching to the Caroline Islands in the north and French Polynesia in the east. It is usually called the grey duck in New Zealand, where it is also known by its Maori name, pārera. This sociable duck is found in a variety of wetland habitats, and its nesting habits are much like those of the mallard, which is encroaching on its range in New Zealand. It feeds by upending, like other Anas ducks. The Pacific Black Duck is mainly vegetarian, feeding on seeds of aquatic plants. This diet is supplemented with small crustaceans, molluscs and aquatic insects. 27104

Dolphin is a common name of aquatic mammals within the infraorder Cetacea. Dolphins range in size from the 1.7 m long and 50 kg Maui's dolphin to the 9.5 m and 10 t killer whale. Several species exhibit sexual dimorphism, in that the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can travel at 55.5 km/h. Dolphins use their conical shaped teeth to capture fast moving prey. They have well-developed hearing which is adapted for both air and water and is so well developed that some can survive even if they are blind. Some species are well adapted for diving to great depths. They have a layer of fat, or blubber, under the skin to keep warm in the cold water. Dolphins are sometimes kept in captivity and trained to perform tricks. The most common dolphin species in captivity is the bottlenose dolphin. 1954

The tiger (Panthera tigris) is the largest species among the Felidae and classified in the genus Panthera. It is most recognisable for its dark vertical stripes on orangish-brown fur with a lighter underside. It is an apex predator, primarily preying on ungulates such as deer and wild boar. It is territorial and generally a solitary but social predator, requiring large contiguous areas of habitat, which support its requirements for prey and rearing of its offspring. Tiger cubs stay with their mother for about two years, before they become independent and leave their mother's home range to establish their own. The tiger once ranged widely from the Eastern Anatolia Region in the west to the Amur River basin, and in the south from the foothills of the Himalayas to Bali in the Sunda islands. Since the early 20th century, tiger populations have lost at least 93% of their historic range and have been extirpated in Western and Central Asia, from the islands of Java and Bali, and in large areas of Southeast and South Asia and China. Today's tiger range is fragmented, stretching from Siberian temperate forests to subtropical and tropical forests on the Indian subcontinent and Sumatra. The tiger is listed as endangered. 15147

Marine life, or sea life or ocean life, is the plants, animals and other organisms that live in the salt water of the sea or ocean, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet. Marine organisms produce oxygen and sequester carbon. Shorelines are in part shaped and protected by marine life, and some marine organisms even help create new land. The term marine comes from the Latin mare, meaning sea or ocean. Most life forms evolved initially in marine habitats. By volume, oceans provide about 90 percent of the living space on the planet. The earliest vertebrates appeared in the form of fish, which live exclusively in water. Some of these evolved into amphibians which spend portions of their lives in water and portions on land. Other fish evolved into land mammals and subsequently returned to the ocean as seals, dolphins or whales. Plant forms such as kelp and algae grow in the water and are the basis for some underwater ecosystems. Plankton forms the general foundation of the ocean food chain, particularly the phytoplankton which are key primary producers. Marine invertebrates exhibit a wide range of modifications to survive in poorly oxygenated waters, including breathing tubes as in mollusc siphons. Fish have gills instead of lungs, although some species of fish, such as the lungfish, have both. Marine mammals, such as dolphins, whales, otters, and seals need to surface periodically to breathe air. There are over 200,000 documented marine species with perhaps two million marine species yet to be documented. Marine species range in size from the microscopic, including phytoplankton which can be as small as 0.02 micrometres, to huge cetaceans (whales, dolphins and porpoises), including the blue whale – the largest known animal reaching 33 metres in length. Marine microorganisms, including protists, bacteria and viruses, constitute about 70% of the total marine biomass. 31150

The Great Barrier Reef is the world's largest coral reef system composed of over 2,900 individual reefs and 900 islands stretching for over 2,300 kilometres over an area of approximately 344,400 square kilometres. The Great Barrier Reef is a distinct feature of the East Australian Cordillera division. It reaches from Torres Strait (between Bramble Cay, its northernmost island, and the south coast of Papua New Guinea) in the north to the unnamed passage between Lady Elliot Island (its southernmost island) and Fraser Island in the south. Lady Elliot Island is located 1,915 km southeast of Bramble Cay as the crow flies. It includes the smaller Murray Islands. The reef is located in the Coral Sea, off the coast of Queensland, Australia. The Great Barrier Reef can be seen from outer space and is the world's biggest single structure made by living organisms. This reef structure is composed of and built by billions of tiny organisms, known as coral polyps. It supports a wide diversity of life and was selected as a World Heritage Site in 1981. The Great Barrier Reef has long been known to and used by the Aboriginal Australian and Torres Strait Islander peoples, and is an important part of local groups' cultures and spirituality. The reef is a very popular destination for tourists, especially in the Whitsunday Islands and Cairns regions. Tourism is an important economic activity for the region, generating over A$3 billion per year. 22881

Rainbow lorikeets are true parrots, within the Psittacoidea superfamily in the order Psittaciformes. The rainbow lorikeet or lorikeet (Trichoglossus moluccanus) is a species of parrot found in Australia. It is common along the eastern seaboard, from northern Queensland to South Australia. Its habitat is rainforest, coastal bush and woodland areas. They are true parrots of medium-size, with the length ranging from 25 to 30 cm, including the tail. The weight varies from 75 to 157 g. The plumage of the nominate race, as with all subspecies, is very bright. The 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. 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. 2320

The pied stilt (Himantopus leucocephalus), also known as the white-headed stilt, is a shorebird in the family Recurvirostridae. It is widely distributed with a large total population size and apparently stable population trend, occurring in Malaysia, Japan, the Philippines, Brunei, Christmas Island, Indonesia, Palau, Papua New Guinea, Australia, and New Zealand. It is listed as Least Concern on the IUCN Red List. It is sometimes considered a subspecies of the black-winged stilt (H. himantopus). The pied stilt grows to a length of about 36 cm with a wingspan of about 67 cm. The back of the head and neck, the back and the upper surfaces of the wings are glossy greenish-black. The undersides of the wings are plain black and the remainder of the plumage is white, apart from the tail feathers which are tinged with grey. The long, thin legs are pink and the toes have black claws. The long slender beak is black and the irises and the eyelids are red. The pied stilt is resident in southern Sumatra, Java, Sulawesi and most of Australia, New Zealand and Papua New Guinea. There are non-breeding populations in Sri Lanka, the Philippines, Brunei, Palau, South Kalimantan, West Nusa Tenggara, East Nusa Tenggara, East Timor and New Guinea. This bird is a vagrant to Japan and Christmas Island. The pied stilt is a waterbird and feeds in shallow water, probing into the sediment with its beak. It is gregarious, and in New Zealand sometimes forms mixed flocks with the black stilt (Himantopus novaezelandiae). It feeds largely on aquatic insects and on small molluscs. It emits a repeated yelping cry as it flies, and the legs trail behind it, tending to sway from side-to-side. 28062

The Australian magpie (Gymnorhina tibicen) is a medium-sized black and white passerine bird native to Australia and southern New Guinea. Although once considered to be three separate species, it is now considered to be one, with nine recognised subspecies. A member of the Artamidae, the Australian magpie is placed in its own genus and is most closely related to the black butcherbird (Melloria quoyi). Currawongs have yellow eyes, whereas Magpies have red-brown eyes and Butcherbirds have very dark brown, almost black eyes. It is not, however, closely related to the European magpie, which is a corvid. The adult Australian magpie is a fairly robust bird ranging from 37 to 43 cm in length, with distinctive black and white plumage, gold brown eyes and a solid wedge-shaped bluish-white and black bill. The male and female are similar in appearance, and can be distinguished by differences in back markings. The male has pure white feathers on the back of the head and the female has white blending to grey feathers on the back of the head. With its long legs, the Australian magpie walks rather than waddles or hops and spends much time on the ground. Described as one of Australia's most accomplished songbirds, the Australian magpie has an array of complex vocalisations. It is omnivorous, with the bulk of its varied diet made up of invertebrates. It is generally sedentary and territorial throughout its range. Common and widespread, it has adapted well to human habitation and is a familiar bird of parks, gardens and farmland in Australia and New Guinea. This species is commonly fed by households around the country, but in spring (and occasionally in autumn) a small minority of breeding magpies (almost always males) become aggressive and swoop and attack those who approach their nests. 21448

The eastern blue-tongued lizard (Tiliqua scincoides scincoides) is a subspecies of large skink which is common throughout eastern Australia, often found in bushland and suburban areas where conditions are suitable. The lizard is known as blue-tongue because its tongue can range from bright to dark blue, and it has a habit of displaying it prominently and hissing loudly when disturbed. The eastern blue-tongued lizard is a stout and slow lizard with brown to grey scales and a barred pattern across the body and tail. The underside is usually pale. Blue-tongued lizards are popular as pets and can live up to 30 years in captivity. They give birth to live young, between six and a record 20 per litter. The young consume the egg sac immediately after birth. They resemble the adult form closely. Several other types of blue-tongued lizard are in the genus Tiliqua, such as the northern blue-tongued skink and the shingleback or stump-tailed skink. 16594
