128-566: The Australian pelican ( Pelecanus conspicillatus ) is a large waterbird in the family Pelecanidae , widespread on the inland and coastal waters of Australia and New Guinea , also in Fiji , parts of Indonesia and as a vagrant in New Zealand. It is a predominantly white bird with black wings and a pink bill. It has been recorded as having the longest bill of any living bird. It mainly eats fish, but will also consume birds and scavenge for scraps if
256-594: A complex communal courtship involving a group of males chasing a single female in the air, on land, or in the water while pointing, gaping, and thrusting their bills at each other. They can finish the process in a day. The tree-nesting species have a simpler process in which perched males advertise for females. The location of the breeding colony is constrained by the availability of an ample supply of fish to eat, although pelicans can use thermals to soar and commute for hundreds of kilometres daily to fetch food. The Australian pelican has two reproductive strategies depending on

The Japanese invaded the north shore of the Australia territories and were aiming to move south and take the southern shore too. The highlands, northern and eastern parts of the island became key battlefields in the South West Pacific Theatre of World War II . Notable battles were for Port Moresby (the naval battle
512-615: A fish eater, the Australian pelican is also an eclectic and opportunistic scavenger and carnivore that forages in landfill sites, as well as taking carrion and "anything from insects and small crustaceans to ducks and small dogs". Food is not stored in a pelican's throat pouch, contrary to popular folklore. Pelicans may also eat birds. In southern Africa, eggs and chicks of the Cape cormorant are an important food source for great white pelicans. Several other bird species have been recorded in

The flora of New Guinea is a mixture of many tropical rainforest species with origins in Asia, together with typically Australasian flora. Typical Southern Hemisphere flora include the conifers Podocarpus and the rainforest emergents Araucaria and Agathis , as well as tree ferns and several species of Eucalyptus . New Guinea has 284 species and six orders of mammals: monotremes , three orders of marsupials , rodents and bats ; 195 of
768-579: A long history of cultural significance in mythology , and in Christian and heraldic iconography . The name comes from the Ancient Greek word pelekan (πελεκάν), which is itself derived from the word pelekys (πέλεκυς) meaning "axe". In classical times, the word was applied to both the pelican and the woodpecker. The genus Pelecanus was first formally described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae . He described

Ethnologue 's 14th edition lists 826 languages of Papua New Guinea and 257 languages of Western New Guinea , total 1073 languages, with 12 languages overlapping. They can be divided into two groups, the Austronesian languages , and all the others placed in the catch-all category of Papuan languages , most of which are unrelated. The separation
1024-627: A new name because of the negative association of Papua . Frans Kaisiepo , the committee leader, suggested the name from Mansren Koreri myths, Iri-an from the Biak language of Biak Island , meaning "hot land" (referring to the climate), but also from Iryan which means heated process as a metaphor for a land that is entering a new era. In Serui Iri-an ( lit. "land-nation") means "pillar of nation", while in Merauke Iri-an ( lit. "placed higher-nation") means "rising spirit" or "to rise". The name
1152-485: A part of Indonesia and is organized as the provinces of Papua , Central Papua , Highland Papua , South Papua , Southwest Papua , and West Papua . The two major cities on the island are Port Moresby and Jayapura . The island has been known by various names: The name Papua was used to refer to parts of the island before contact with the West. Its etymology is unclear; one theory states that it derived from Tidore ,
1280-519: A phenomenon known as ground effect to reduce drag and increase lift . As the air flows between the wings and the water surface, it is compressed to a higher density and exerts a stronger upward force against the bird above. Hence, substantial energy is saved while flying. Adult pelicans rely on visual displays and behaviour to communicate, particularly using their wings and bills. Agonistic behaviour consists of thrusting and snapping at opponents with their bills, or lifting and waving their wings in
1408-716: A seeming preference for the perch Leiopotherapon unicolor . However, the Australian pelican seems to be less of a piscivore and more catholic in taste than other pelicans. It regularly feeds on insects and many aquatic crustaceans , especially the common yabby , prawns and the shrimps in the genus Macrobrachium . This pelican also takes other birds with some frequency, such as silver gulls , Australian white ibis and grey teal , including eggs, nestlings, fledglings and adults, which they may kill by pinning them underwater and drowning them. Reptiles , amphibians and small mammals are also taken when available. Reportedly even small dogs have been swallowed. The Australian pelican

Rarely, slightly more elaborate nests have also been observed on top of Muehlenbeckia florulenta bushes. Nesting is communal, with colonies located on islands (such as the North Peron Island ) or sheltered areas in the vicinity of lakes or the sea. Breeding Australian pelicans will lay one to four (typically two) chalky-white eggs measuring 93 mm × 57 mm (3.7 in × 2.2 in), which often appear scratched and dirty. The eggs are incubated for 32 to 35 days. The chicks are naked when they hatch, though quickly grow grey down feathers. After they hatch,
1664-487: A similar technique is the Peruvian pelican, but its dives are typically from a lower height than the brown pelican. The Australian and American white pelicans may feed by low plunge-dives landing feet-first and then scooping up the prey with the beak, but they—as well as the remaining pelican species—primarily feed while swimming on the water. Aquatic prey is most commonly taken at or near the water surface. Although principally

The bones were later described as a new (sub)species, Pelecanus (conspicillatus) novaezealandiae (Scarlett, 1966: "New Zealand pelican") as they appeared to be larger, but Worthy (1998), reviewing new material, determined that they were not separable from
1920-420: A threatening manner. Adult pelicans grunt when at the colony, but are generally silent elsewhere or outside breeding season. Conversely, colonies are noisy, as chicks vocalise extensively. Pelicans are gregarious and nest colonially. Pairs are monogamous for a single season, but the pair bond extends only to the nesting area; mates are independent away from the nest. The ground-nesting (white) species have
2048-412: A valid description. Fossil finds from North America have been meagre compared with Europe, which has a richer fossil record. Several Pelecanus species have been described from fossil material, including: Pelicans are very large birds with very long bills characterised by a downcurved hook at the end of the upper mandible, and the attachment of a huge gular pouch to the lower. The slender rami of

Tropicbirds , darters , cormorants, gannets, boobies, and frigatebirds, all traditional members of the order, have since been reclassified: tropicbirds into their own order, Phaethontiformes , and the remainder into the Suliformes. In their place, herons, ibises, spoonbills, the hamerkop, and the shoebill have now been transferred into the Pelecaniformes. Molecular evidence suggests that
2304-436: A week, they are able to put their heads into their parents' pouches and feed themselves. Sometimes before, but especially after being fed the pelican chick may seem to "throw a tantrum" by loudly vocalizing and dragging itself around in a circle by one wing and leg, striking its head on the ground or anything nearby and the tantrums sometimes end in what looks like a seizure that results in the chick falling briefly unconscious;

Archaeological evidence indicates that humans may have inhabited the island continuously since 50,000 BCE, and first settlement possibly dating back to 60,000 years ago has been proposed. The island is presently populated by almost a thousand different tribal groups and

During courtship, the orbital skin and distal quarter of the bill are orange-coloured with the pouch variously turning dark blue, pink and scarlet. The non-breeding adult has its bill and eye-ring a pale yellow and the pouch is a pale pinkish. Juvenile birds are similar to the adults, but with black replaced with brown and

The Australian pelican begins breeding at two or three years of age. The breeding season varies, occurring in winter in tropical areas (north of 26°S) and spring in parts of southern Australia. Breeding may occur any time after rainfall in inland areas. The nest is

Various other smaller mountain ranges occur both north and west of the central ranges. Except in high elevations, most areas possess a warm humid climate throughout the year, with some seasonal variation associated with the northeast monsoon season. Another major habitat feature
3072-773: Is considered to be near threatened in the IUCN Red List of Threatened Species. Numbers declined substantially during the 20th century, one crucial factor being the eradication of the important Sittaung valley breeding colony in Burma through deforestation and the loss of feeding sites. The chief threats it faces are from habitat loss and human disturbance, but populations have mostly stabilised following increased protection in India and Cambodia. New Guinea New Guinea ( Tok Pisin : Niugini ; Hiri Motu : Niu Gini ; Indonesian : Papua , fossilized Nugini , or historically Irian )

Anatomical dissections of two brown pelicans in 1939 showed that pelicans have a network of air sacs under their skin situated across the ventral surface including the throat, breast, and undersides of the wings, as well as having air sacs in their bones. The air sacs are connected to
3328-541: Is highly variable. Pelicans live for 15 to 25 years in the wild, although one reached an age of 54 years in captivity. The diet of pelicans usually consists of fish, but occasionally amphibians , turtles, crustaceans , insects , birds, and mammals are also eaten. The size of the preferred prey fish varies depending on pelican species and location. For example, in Africa, the pink-backed pelican generally takes fish ranging in size from fry up to 400 g (0.9 lb) and
3456-763: Is home to an estimated 44 uncontacted tribal groups . With some 786,000 km of tropical land—less than one-half of one percent (0.5%) of the Earth's surface—New Guinea has an immense biodiversity , containing between 5 and 10 percent of the total species on the planet. This percentage is about the same amount as that found in the United States or Australia. A high percentage of New Guinea's species are endemic , and thousands are still unknown to science: probably well over 200,000 species of insect, between 11,000 and 20,000 plant species, and over 650 resident bird species. Most of these species are shared, at least in their origin, with

Due to the popularity of open water sports, the habitat of the Australian pelican has suffered considerably less than more vegetated wetlands throughout Australia. The Australian pelican is evaluated as a least-concern species on the IUCN Red List of Threatened Species . In parts of South Australia the pelican is known by its Ngaarrindjeri name, nori . It was
3968-698: Is not globally threatened. They are usually fairly common in proper habitats. At the aforementioned temporary inundation of Lake Eyre in March 1990, over 200,000 adult birds were found to be breeding. The species is legally protected and does not seem to be showing any immediate adverse effects from pollution. In several areas, such as the beach at Monkey Mia , Western Australia and at The Entrance, New South Wales , pelicans may associate with humans and may even beg for hand-outs, but they are quite sensitive to human disturbances while nesting. They will readily adapt to artificial bodies of water such as reservoirs so long as there

9216-516: The east of the Malay Archipelago , with which it is sometimes included as part of a greater Indo-Australian Archipelago. Geologically it is a part of the same tectonic plate as Australia. When world sea levels were low, the two shared shorelines (which now lie 100 to 140 metres below sea level), and combined with lands now inundated into the tectonic continent of Sahul , also known as Greater Australia. The two landmasses became separated when
9344-468: The egg-laying monotreme , the echidna . Other than bats and some two dozen indigenous rodent genera, there are no pre-human indigenous placental mammals . Pigs, several additional species of rats, and the ancestor of the New Guinea singing dog were introduced with human colonization. Prior to the 1970s, archaeologists called the single Pleistocene landmass by the name Australasia , although this word
9472-979: The eggs and nestlings of cattle egrets and nestling great egrets in Baja California , Mexico. Peruvian pelicans in Chile have been recorded feeding on nestlings of imperial shags , juvenile Peruvian diving petrels , and grey gulls . Cannibalism of chicks of their own species is known from the Australian, brown, and Peruvian pelicans. Non-native great white pelicans have been observed swallowing city pigeons in St. James's Park in London, England. Globally, pelican populations are adversely affected by these main factors: declining supplies of fish through overfishing or water pollution, destruction of habitat, direct effects of human activity such as disturbance at nesting colonies, hunting and culling, entanglement in fishing lines and hooks, and
9600-438: The estuary, making it the longest river in New Guinea. The winding, muddy, sluggish river can be navigated for 500 km. Ramu is a 650 km long river. Its lower section is navigable, but its upper flow is high-falling, fast-flowing. The energy of the river is used by a power plant near the city of Kainantu . On the south side, the most significant rivers are Pulau , Digul, Fly, Kikori and Purari . The largest river in
9728-457: The global population of the brown pelican at 300,000. Numbers of brown pelican plummeted in the 1950s and 1960s, largely as a consequence of environmental DDT pollution, and the species was listed as endangered in the US in 1970. With restrictions on DDT use in the US from 1972, its population has recovered, and it was delisted in 2009. The Peruvian pelican is listed as near threatened because, although
9856-448: The great white pelican prefers somewhat larger fish, up to 600 g (1.3 lb), but in Europe, the latter species has been recorded taking fish up to 1,850 g (4.1 lb). In deep water, white pelicans often fish alone. Nearer the shore, several encircle schools of small fish or form a line to drive them into the shallows, beating their wings on the water surface and then scooping up
9984-410: The gullet head-first. A gull will sometimes stand on the pelican's head, peck it to distraction, and grab a fish from the open bill. Pelicans in their turn sometimes snatch prey from other waterbirds. The brown pelican usually plunge-dives head-first for its prey, from a height as great as 10–20 m (33–66 ft), especially for anchovies and menhaden . The only other pelican to feed using
10112-589: The highlands were an early and independent center of agriculture, with evidence of irrigation going back at least 10,000 years. Sugarcane was cultivated in New Guinea around 6000 BCE. The gardens of the New Guinea Highlands are ancient, intensive permacultures , adapted to high population densities, very high rainfalls (as high as 10,000 mm per year (400 in/yr)), earthquakes, hilly land, and occasional frost. Complex mulches, crop rotations and tillages are used in rotation on terraces with complex irrigation systems. Western agronomists still do not understand all of
10240-564: The island and the province. The name Irian , which was originally favored by natives, is now considered to be a name imposed by the authority of Jakarta . New Guinea is an island to the north of the Australian mainland , south of the equator. It is isolated by the Arafura Sea to the west, and the Torres Strait and Coral Sea to the east. Sometimes considered to be the easternmost island of
10368-539: The islands of Wallacea and Sundaland (the present Malay Archipelago ) by at least 40,000 years ago. The ancestral Austronesian peoples are believed to have arrived considerably later, approximately 3,500 years ago, as part of a gradual seafaring migration from Southeast Asia , possibly originating in Taiwan. Austronesian-speaking peoples colonized many of the offshore islands to the north and east of New Guinea, such as New Ireland and New Britain , with settlements also on
10496-636: The language used by the Sultanate of Tidore . An expedition by the Sultan of Tidore , together with Sahmardan, the Sangaji of Patani , and the Papuan Gurabesi , managed to conquer some areas in New Guinea, which was then reorganised to form Korano Ngaruha ("Four Kings") or Raja Ampat , Papoua Gam Sio ( lit. "The Papua Nine Negeri "), and Mafor Soa Raha ( lit. The Mafor "Four Soa "). The name comes from
10624-411: The larger one will be fed more, and the smaller one will eventually die of starvation or siblicide . For the first two weeks the chicks will be fed regurgitated liquid, but for the remaining two months they will be fed fish and some invertebrates . Feeding pods are formed within colonies when the chicks are around 25 days. The young pelicans fledge at around three months of age. The Australian pelican
10752-575: The local degree of environmental predictability. Colonies of tens or hundreds, rarely thousands, of birds breed regularly on small coastal and subcoastal islands where food is seasonally or permanently available. In arid inland Australia, especially in the endorheic Lake Eyre basin , pelicans breed opportunistically in very large numbers of up to 50,000 pairs, when irregular major floods, which may be many years apart, fill ephemeral salt lakes and provide large amounts of food for several months before drying out again. In all species, copulation takes place at
10880-404: The lower bill and the flexible tongue muscles form the pouch into a basket for catching fish, and sometimes rainwater, though to not hinder the swallowing of large fish, the tongue itself is tiny. They have a long neck and short stout legs with large, fully webbed feet. Although they are among the heaviest of flying birds, they are relatively light for their apparent bulk because of air pockets in
11008-435: The main exports of the island during this period were resins, spices, slaves and the highly priced feathers of the bird-of-paradise . In a period of constant conflict called 'hongi wars', in which rival villages or kingdoms would invoke the name of Tidore Sultan, rightly, for punitive expeditions for not fulfilling their tributary obligations, or opportunitively for competitions over resources and prestige. Sultan Nuku , one of
11136-536: The main island as part of the Dutch East Indies , they called it Nieuw Guinea . The name Irian was used in the Indonesian language to refer to the island and Indonesian province, as Irian Barat (West Irian) Province and later Irian Jaya Province. The name Irian was suggested during a tribal committee meeting in Tobati, Jayapura, formed by Soegoro Atmoprasodjo under governor JP van Eechoed, to decide on
11264-578: The mainland of the country of Papua New Guinea . The shape of New Guinea is often compared to that of a bird-of-paradise (indigenous to the island), and this results in the usual names for the two extremes of the island: the Bird's Head Peninsula in the northwest ( Vogelkop in Dutch, Kepala Burung in Indonesian; also known as the Doberai Peninsula), and the Bird's Tail Peninsula in the southeast (also known as
11392-472: The mammal species (69%) are endemic. New Guinea has 578 species of breeding birds, of which 324 species are endemic. The island's frogs are one of the most poorly known vertebrate groups, totalling 282 species, but this number is expected to double or even triple when all species have been documented. New Guinea has a rich diversity of coral life and 1,200 species of fish have been found. Also about 600 species of reef-building coral—the latter equal to 75 percent of
11520-535: The most famous Tidore sultans who rebelled against Dutch colonization, called himself "Sultan of Tidore and Papua", during his revolt in 1780s. He commanded loyalty from both Moluccan and Papuan chiefs, especially those of Raja Ampat Islands, from his base in Gebe . Following Tidore's subjugation as Dutch tributary, much of the territory it claimed in western part of New Guinea came under Dutch rule as part of Dutch East Indies. The first known European contact with New Guinea
11648-544: The mouth of the river in 1845. The total length of the river is 1,050 km. Smaller boats can sail 900 km on the river. The estuary section, which decomposes into islands, is 70 km wide. The tide of the sea can have an effect of up to 300 kilometers. Strickland , a tributary of the Fly, reaches the Papuan Plain through wild gorges. Fly and Strickland together form the largest river in New Guinea. The many rivers flowing into
11776-429: The nest site; it begins shortly after pairing and continues for 3–10 days before egg-laying. The male brings the nesting material, in ground-nesting species (which may not build a nest) sometimes in the pouch, and in tree-nesting species crosswise in the bill. The female then heaps the material up to form a simple structure. The eggs are oval, white, and coarsely textured. All species normally lay at least two eggs;
11904-679: The opportunity arises. The Australian pelican was first described by Dutch naturalist Coenraad Jacob Temminck in 1824. Its specific epithet is derived from the Latin verb conspicere , meaning 'to behold', and refers to the 'spectacled' appearance created by its conspicuous eye markings. The Australian pelican is medium-sized by pelican standards, with a wingspan of 2.3 to 2.6 m (7.5 to 8.5 ft). Weight can range from 4 to 13 kg (8.8 to 28.7 lb), although most of these pelicans weigh between 4.54 and 7.7 kg (10.0 and 17.0 lb). The average weight of four unsexed Australian pelicans
12032-499: The others by placement in the subgenus Leptopelecanus but in fact species with both sorts of appearance and nesting behavior are found in either. DNA sequencing of both mitochondrial and nuclear genes yielded quite different relationships; the three New World pelicans formed one lineage, with the American white pelican sister to the two brown pelicans, and the five Old World species the other. The Dalmatian, pink-backed, and spot-billed were all closely related to one another, while
12160-544: The partial elected New Guinea Council took office on 5 April 1961. The Council decided on the name of West Papua ( Papua Barat ) for the territory, along with an emblem, flag , and anthem to complement those of the Netherlands. On 1 October 1962, after some military interventions and negotiations, the Dutch handed over the territory to the United Nations Temporary Executive Authority , until 1 May 1963, when Indonesia took control. The territory
12288-599: The pelican lineage has existed for at least 36 million years; the oldest known pelican fossil was assigned to Eopelecanus aegyptiacus and was found in late Eocene (middle to late part of the early Priabonian stage/age) deposits of the Birket Qarun Formation within the Wadi Al-Hitan World Heritage Site in Egypt. A more complete fossil pelican of early Oligocene age is known from deposits at
12416-643: The population dispersed once more, flocks of thousands being seen on the northern coasts. On some occasions, they are simply blown by the wind to new locations. It is a fairly regular visitor to the southern coast of New Guinea , as well as the Bismarck Islands and Solomon Islands . It occurs as a vagrant to Christmas Island , Vanuatu , Fiji , Palau and New Zealand . A population irruption occurred in 1978 into Indonesia , with Australian pelicans reaching Sulawesi , Java and possibly also Sumatra . Australian pelicans feed by plunge-diving while swimming on
12544-586: The population is estimated by BirdLife International to exceed 500,000 mature individuals, and is possibly increasing, it has been much higher in the past. It declined dramatically during the 1998 El Niño event and could experience similar declines in the future. Conservation needs include regular monitoring throughout the range to determine population trends, particularly after El Niño years, restricting human access to important breeding colonies, and assessing interactions with fisheries. The spot-billed pelican has an estimated population between 13,000 and 18,000 and
12672-480: The practices, and it has been noted that native gardeners are as, or even more, successful than most scientific farmers in raising certain crops. There is evidence that New Guinea gardeners invented crop rotation well before western Europeans. A unique feature of New Guinea permaculture is the silviculture of Casuarina oligodon , a tall, sturdy native ironwood tree, suited to use for timber and fuel, with root nodules that fix nitrogen. Pollen studies show that it
12800-560: The presence of pollutants such as DDT and endrin . Most species' populations are more or less stable, although three are classified by the IUCN as being at risk. All species breed readily in zoos, which is potentially useful for conservation management. The combined population of brown and Peruvian pelicans is estimated at 650,000 birds, with around 250,000 in the United States and Caribbean, and 400,000 in Peru. The National Audubon Society estimates
12928-429: The prey. Although all pelican species may feed in groups or alone, the Dalmatian, pink-backed, and spot-billed pelicans are the only ones to prefer solitary feeding. When fishing in groups, all pelican species have been known to work together to catch their prey, and Dalmatian pelicans may even cooperate with great cormorants . Large fish are caught with the bill-tip, then tossed up in the air to be caught and slid into
13056-473: The range of interspecific variation in Pelecanus . The Late Eocene Protopelicanus may be a pelecaniform or suliform – or a similar aquatic bird such as a pseudotooth ( Pelagornithidae ), but is not generally considered a pelecanid . The supposed Miocene pelican Liptornis from Patagonia is a nomen dubium (of doubtful validity), being based on fragments providing insufficient evidence to support
13184-735: The reason is not clearly known, but a common belief is that it is to draw attention to itself and away from any siblings who are waiting to be fed. Parents of ground-nesting species sometimes drag older young around roughly by the head before feeding them. From about 25 days old, the young of these species gather in "pods" or " crèches " of up to 100 birds in which parents recognise and feed only their own offspring. By 6–8 weeks they wander around, occasionally swimming, and may practise communal feeding. Young of all species fledge 10–12 weeks after hatching. They may remain with their parents afterwards, but are now seldom or never fed. They are mature at three or four years old. Overall breeding success
13312-605: The region of Wanin and Sran, in eastern Nusantara as part of Majapahit 's tributary. This 'Wanin' has been identified with the Onin Peninsula, part of the Bomberai Peninsula near the city of Fakfak . while ' Sran ' had been identified as region of Kowiai , just south of Onin peninsula. The sultans of Tidore , in the Maluku Islands , claimed sovereignty over various coastal parts of the island. During Tidore's rule,
13440-532: The richest coral reefs on the planet. The entire length of the New Guinea Highlands system passes through New Guinea as a vast watershed. The northern rivers flow into the Pacific Ocean , the southern rivers into the Arafura Sea and the Gulf of Papua . On the north side, the largest rivers are the Mamberamo, Sepik and Ramu. Mamberamo was born from the confluence of two large inland rivers. Tariku comes from
13568-467: The seas bordering New Guinea: The first inhabitants Indigenous people of New Guinea , from whom the Papuan people are probably descended, adapted to the range of ecologies and, in time, developed one of the earliest known agricultures. Remains of this agricultural system, in the form of ancient irrigation systems in the highlands of Papua New Guinea, are being studied by archaeologists. Research indicates that
13696-1475: The shoebill and the hamerkop form a sister group to the pelicans, though some doubt exists as to the exact relationships among the three lineages. The oldest known record of Pelicans is a right tibiotarsus very similar to those of modern species from the Birket Qarun Formation in the Wadi El Hitan in Egypt, dating to the late Eocene ( Priabonian ), referred to the genus Eopelecanus . P. rufescens P. philippensis P. crispus P. conspicillatus P. onocrotalus P. occidentalis P. thagus P. erythrorhynchos Suliformes Herons (Ardeidae) Ibises and spoonbills (Threskiornithidae) Hamerkop ( Scopus umbretta ) Shoebill ( Balaeniceps rex ) Pelicans ( Pelecanus ) Cladogram based on Hackett et al. (2008). The eight living pelican species were traditionally divided into two groups, one containing four ground-nesters with mainly white adult plumage ( Australian , Dalmatian , great white , and American white pelicans ), and one containing four grey- or brown-plumaged species which nest preferentially either in trees ( pink-backed , spot-billed and brown pelicans ), or on sea rocks ( Peruvian pelican ). The largely marine brown and Peruvian pelicans, formerly considered conspecific , are sometimes separated from
13824-487: The skeleton and beneath the skin, enabling them to float high in the water. The tail is short and square. The wings are long and broad, suitably shaped for soaring and gliding flight, and have the unusually large number of 30 to 35 secondary flight feathers . Males are generally larger than females and have longer bills. The smallest species is the brown pelican, small individuals of which can be no more than 2.75 kg (6.1 lb) and 1.06 m (3.5 ft) long, with
13952-568: The skin of the throat and pouch with the bill open to promote evaporative cooling . They roost and loaf communally on beaches, sandbanks, and in shallow water. A fibrous layer deep in the breast muscles can hold the wings rigidly horizontal for gliding and soaring. Thus, they use thermals for soaring to heights of 3000 m (10,000 ft) or more, combined both with gliding and with flapping flight in V formation , to commute distances up to 150 km (93 mi) to feeding areas. Pelicans also fly low (or "skim") over stretches of water, using
14080-568: The south at the border with British New Guinea . The German, Dutch and British colonial administrators each attempted to suppress the still-widespread practices of inter-village warfare and headhunting within their respective territories. In 1905, the British government transferred some administrative responsibility over southeast New Guinea to Australia (which renamed the area " Territory of Papua "); and, in 1906, transferred all remaining responsibility to Australia. During World War I , Australian forces seized German New Guinea, which in 1920 became
14208-458: The surface of the water. They work in groups to drive fish to shallower water, where they stick their sensitive bills in to snatch their prey. Some feeding grounds in large bodies of water have included up to 1,900 individual birds. They will sometimes also forage solitarily. Their predominant prey is fish and they commonly feed on introduced species such as goldfish , European carp and European perch . When possible, they also eat native fish, with
14336-512: The usual clutch size is one to three, rarely up to six. Both sexes incubate with the eggs on top of or below the feet; they may display when changing shifts. Incubation takes 30–36 days; hatching success for undisturbed pairs can be as high as 95%, but because of sibling competition or siblicide , in the wild, usually all but one nestling dies within the first few weeks (later in the pink-backed and spot-billed species). Both parents feed their young. Small chicks are fed by regurgitation ; after about
14464-740: The water and catching them at/near the water's surface. They can adapt to varying degrees of water salinity , from freshwater and brackish to—most commonly—seawater. 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
14592-538: The west to the east and Taritatu from the east. These rivers meander through swamps with huge internal descents and then merge. The Mamberamo thus formed reaches the ocean by breaking through the Coastal Mountains. Mamberamo River is navigable to Marine Falls. The Sepik is a much more important river. Similarly, it collects water from a spacious pool. It is 1,100 kilometers from the Victor Emanuel Range to
14720-515: The western part of the island in present-day Indonesia, and also claimed the territory for the King of Spain. A successive European claim occurred in 1828, when the Netherlands formally claimed the western half of the island as Netherlands New Guinea . Dutch colonial authority built Fort Du Bus an administrative and trading post established near Lobo, Triton Bay, but by 1835 had been abandoned. Considering that New Guinea had little economic value for them,
14848-602: The western part of the island is Digul . It originates from the Star Mountains , which rise to an altitude of 4,700 m. The coastal plain is bordered by a swamp world hundreds of kilometers wide. Digul is the main transport route to the fertile hills and mountains within the island. The river Fly is born near the eastern branches of the Digul. It is named after one of the ships of the English Royal Fleet, which first sailed into
14976-676: The western side, and by the Sepik on the eastern side. The more extensive southern lowlands are drained by a larger number of rivers, principally the Digul in the west and the Fly in the east. The largest island offshore, Dolak , lies near the Digul estuary, separated by a strait so narrow it has been named a "creek". New Guinea contains many of the world's ecosystem types: glacial, alpine tundra , savanna , montane and lowland rainforest, mangroves , wetlands , lake and river ecosystems , seagrasses , and some of
15104-608: The white patch on upper wing reduced. Overall, their appearance is somewhat similar to several other pelicans, though the species is allopatric . This species can occur in large expanses of mainland Australia and Tasmania . Australian pelicans occur primarily in large expanses of open water without dense aquatic vegetation. The habitats that can support them include large lakes, reservoirs , billabongs and rivers, as well as estuaries, swamps, temporarily flooded areas in arid zones, drainage channels in farmland, salt evaporation ponds and coastal lagoons . The surrounding environment
15232-494: The words papo ("to unite") and ua (negation), which means "not united", i.e. an outlying possession of Tidore. Anton Ploeg reports that the word papua is often said to be derived from the Malay word papua or pua-pua , meaning "frizzly-haired", referring to the very curly hair of the island's inhabitants. However Sollewijn Gelpke in 1993 considered this unlikely as it had been used earlier, and he instead derived it from
15360-454: The world and, having never seen Europeans before, initially believed the explorers to be spirits of the dead due to the local belief that a person's skin turned white when they died and crossed into the land of the dead. Netherlands New Guinea and the Australian territories (the eastern half ) were invaded in 1942 by the Japanese . The Netherlands were defeated by that stage and did not put up
15488-661: The world's known total. The entire coral area covers 18 million hectares off a peninsula in northwest New Guinea. As of 2020, the Western portion of New Guinea, Papua and West Papua, accounts for 54% of the island's primary forest and about 51% of the island's total tree cover, according to satellite data. According to the WWF , New Guinea can be divided into twelve terrestrial ecoregions : The WWF and Nature Conservancy divide New Guinea into five freshwater ecoregions : The WWF and Nature Conservancy identify several marine ecoregions in
15616-522: The world's most floristically diverse island, surpassing Madagascar (11,488), Borneo (11,165), Java (4,598), and the Philippines (9,432). Biogeographically , New Guinea is part of Australasia rather than the Indomalayan realm, although New Guinea's flora has many more affinities with Asia than its fauna, which is overwhelmingly Australian. Botanically, New Guinea is considered part of Malesia ,
15744-409: Was 5.5 kg (12 lb), making this the second heaviest Australian flying bird species on average, after the brolga , although the male of the more sexually dimorphic Australian bustard weighs a bit more at average and maximum weights (both birds are, of course, much smaller than the cassowary and emu ). The pale, pinkish bill is enormous, even by pelican standards, and is the largest bill in
15872-527: Was adopted during an ancient period of extreme deforestation. In more recent millennia, another wave of people arrived on the shores of New Guinea. These were the Austronesian people , who had spread down from Taiwan , through the South-east Asian archipelago , colonising many of the islands on the way. The Austronesian people had technology and skills extremely well adapted to ocean voyaging and Austronesian language speaking people are present along much of
16000-451: Was by Portuguese and Spanish sailors in the 16th century. In 1526–27, Portuguese explorer Jorge de Meneses saw the western tip of New Guinea and named it ilhas dos Papuas . In 1528, the Spanish navigator Álvaro de Saavedra also recorded its sighting when trying to return from Tidore to New Spain . In 1545, Spaniard Íñigo Ortíz de Retes sailed along the north coast of New Guinea as far as
16128-498: Was empowered to protect the rights of Papuans, raise the status of women in Papua, and to ease religious tensions in Papua; block grants were given for the implementation of the Law as much as $ 266 million in 2004. The Indonesian courts ' enforcement of the Law on Special Autonomy blocked further creation of subdivisions of Papua: although President Megawati Sukarnoputri was able to create
16256-451: Was promoted in 1945 by Marcus Kaisiepo, brother of Frans Kaisiepo . The name was politicized later by Corinus Krey, Marthen Indey , Silas Papare , and others with the Indonesian backronym Ikut Republik Indonesia Anti Nederland ("Join the Republic of Indonesia Oppose the Netherlands"). Irian was used somewhat in 1972. The name was used until 2001, when Papua was again used for
16384-466: Was renamed West Irian ( Irian Barat ) and then Irian Jaya. In 1969, Indonesia, under the 1962 New York Agreement , organised a referendum named the Act of Free Choice , in which the military hand picked Papuan tribal elders to vote for integration with Indonesia. There has been significant reported resistance to Indonesian integration and occupation, both through civil disobedience (such as publicly raising
