Gould's Petrel
Gould's petrel (''Pterodroma leucoptera'') is a species of seabird in the family Procellariidae. The common name commemorates the English ornithologist and bird artist John Gould (1804–1881). Description Gould's petrel is a small gadfly petrel, white below and dark brown and grey above. The species is classified within the subgenus ''Cookilaria'', all members of which have a dark M pattern across the upper wings. Gould's petrel has long narrow wings, a short rounded tail and the head is noticeably dark, with a white forehead and face. Gould's petrel is 30 cm in length with a wingspan of 70 cm and weighs 180–200 g. Males are slightly larger than females. Taxonomy There are two subspecies of Gould's petrel. The nominate subspecies (''Pterodroma leucoptera leucoptera'') breeds on several small islands off the New South Wales coast in Australia, but primarily on Cabbage Tree Island (John Gould Nature Reserve). The other subspecies (''P. l. caledonica'') breed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pisonia Umbellifera
''Ceodes umbellifera'', synonym ''Pisonia umbellifera'', commonly known as the birdlime tree or bird catcher tree, is a species of plant in the Nyctaginaceae family. The evergreen shrub has soft wood, small pink or yellow flowers, and produces cavate brown fruit throughout the period March to April. The species has been categorized under different genera in its documented lifetime, being reallocated between Pisonia and Ceodes. Its former genus, '' Pisonia'', is named after a Dutch scientist, Willem Piso, and ''umbellifera'' is derived from Latin ''umbelliferum'', denoting the species' big, 'shade-carrying' foliage. The tree's fruit often trap insects, small mammals and birds. This is because the sticky sap of the fruit sticks to the skin, fur or feathers of the animal and renders it immovable. As such, ensnared creatures will often die from starvation or be unable to defend themselves from natural predators. It grows throughout the tropical Indo-Pacific. It is native to the An ...

John Gould
John Gould (; 14 September 1804 – 3 February 1881) was an English ornithologist. He published a number of monographs on birds, illustrated by plates produced by his wife, Elizabeth Gould, and several other artists, including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. He has been considered the father of bird study in Australia and the Gould League in Australia is named after him. His identification of the birds now nicknamed "Darwin's finches" played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book, ''On the Origin of Species''. Early life Gould was born in Lyme Regis, the first son of a gardener. Both father and son probably had little education. After working on Dowager Lady Poulett's glass house, his father obtained a position on an estate near Guildford, Surrey, and then in 1818, Gould Snr became foreman in the Royal Gardens of Windsor.

Seabird
Seabirds (also known as marine birds) are birds that are adapted to life within the marine environment. While seabirds vary greatly in lifestyle, behaviour and physiology, they often exhibit striking convergent evolution, as the same environmental problems and feeding niches have resulted in similar adaptations. The first seabirds evolved in the Cretaceous period, and modern seabird families emerged in the Paleogene. In general, seabirds live longer, breed later and have fewer young than other birds do, but they invest a great deal of time in their young. Most species nest in colonies, which can vary in size from a few dozen birds to millions. Many species are famous for undertaking long annual migrations, crossing the equator or circumnavigating the Earth in some cases. They feed both at the ocean's surface and below it, and even feed on each other. Seabirds can be highly pelagic, coastal, or in some cases spend a part of the year away from the sea entirely.

Procellariidae
The family Procellariidae is a group of seabirds that comprises the fulmarine petrels, the gadfly petrels, the diving petrels, the prions, and the shearwaters. This family is part of the bird order Procellariiformes (or tubenoses), which also includes the albatrosses and the storm petrels. The procellariids are the most numerous family of tubenoses, and the most diverse. They range in size from the giant petrels with a wingspan of around , that are almost as large as the albatrosses, to the diving petrels with a wingspan of around that are similar in size to the little auks or dovekies in the family Alcidae. Male and female birds are identical in appearance. The plumage color is generally dull, with blacks, whites, browns and grays. The birds feed on fish, squid and crustacea, with many also taking fisheries discards and carrion. Whilst agile swimmers and excellent in water, petrels have weak legs and can only shuffle on land, with the giant petrels of the genus Macronec ...

Petrel
Petrels are tube-nosed seabirds in the bird order Procellariiformes. Description The common name does not indicate relationship beyond that point, as "petrels" occur in three of the four families within that group (all except the albatross family, Diomedeidae). Having a fossil record that was assumed to extend back at least 60 million years, the Procellariiformes was long considered to be among the older bird groupings, other than the ratites, with presumably distant ties to penguins and loons. However, recent research and fossil finds such as '' Vegavis'' show that the Galliformes (pheasants, grouse and relatives), and Anseriformes (ducks, geese) are still not fully resolved. Known species All the members of the order are exclusively pelagic in distribution—returning to land only to breed. The family Procellariidae is the main radiation of medium-sized true petrels, characterised by united nostrils with medium septum, and a long outer functional primary feather. It ...

Cabbage Tree Island (John Gould Nature Reserve)
Cabbage Tree Island, also known as the John Gould Nature Reserve, is a protected nature reserve and uninhabited continental island lying off the mouth of Port Stephens on the coast of New South Wales, Australia. The reserve and island is named for the Cabbage-tree Palms in the two gullies on the island's western side which are the nesting site of Goulds petrel. It is the principal breeding site of the nominate subspecies of the threatened Gould's petrel and, with the nearby Boondelbah Island where there is also a small colony, has been classified by BirdLife International as an Important Bird Area. Description Cabbage Tree Island is a small and rugged island, about long, on a north-south alignment, by wide. It rises abruptly to a height of . The tree vegetation includes, as well as the cabbage-tree palms, deciduous and sandpaper figs, native plums, and bird-lime trees. History In 1911, a penguin chick was captured on Cabbage Tree Island and taken to Maitland where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Cook
James Cook (7 November 1728Old Style date: 27 October – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the British Royal Navy, famous for his three voyages between 1768 and 1779 in the Pacific Ocean and to New Zealand and Australia in particular. He made detailed maps of Newfoundland prior to making three voyages to the Pacific, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand. Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War and subsequently surveyed and mapped much of the entrance to the St. Lawrence River during the siege of Quebec, which brought him to the attention of the Admiralty and the Royal Society. This acclaim came at a crucial moment for the direction of British overseas exploration, and it led to his commission in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broughton Island (New South Wales)
Broughton Island is an island 14 km north-east of Port Stephens, New South Wales, Australia. It is part of the Myall Lakes National Parkbr>(map) History Archaeology indicates that the certain ancestors of the Worimi people inhabited the island for an otherwise apparently indeterminate period of two-thousand years, and whatever name those people may have had for the island itself remains unknown. It lay within the territory of the Garrawerrigal branch (''nurra'') of the Woromi. "Garrawerrigal" meant "the people of the sea", from ''garoowa''=sea. ''Niritba'' was "the home of the mutton bird" in their language. Broughton Island was seen by James Cook commanding HM Bark ''Endeavour'' on 11 May 1770: he mistook it for a headland and called it Black Head. After its insularity was discovered, it was renamed Broughton Islands, and so appears on the 1852 Admiralty chart, ''Australia, East Coast. Broken Bay to Sugarloaf Point, from a running survey by Captn. J. Lort Stokes, H.M. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of The Pacific Ocean
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...
