Hoary-headed Grebe
The hoary-headed grebe (''Poliocephalus poliocephalus'') is a member of the grebe family. It breeds in southern parts of Australia; it winters throughout the island of Tasmania. The bird takes its name from the silvery-white streaking on its black head. It is common in Australia, with a population of about 500,000. Its habitat is similar to that of the Australasian grebe. Description The hoary-headed grebe is a fairly small dark grey and white grebe. It has a brown eye and a black patch under the chin, and a narrow black streak down the back of the neck. During the breeding season the adult's plumage has white streaks over its entire head, giving them the common name of hoary-headed grebe. Juveniles have a white chin and throat and a striped face. Males have two plumage phases: after breeding they lose the buff breast and the white lines on the head, but can usually be identified then by the broad black bar down the nape. Distribution and habitat The hoary-headed grebe is found ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prideaux John Selby
Prideaux John Selby FRSE FLS (23 July 1788 – 27 March 1867) was an English ornithologist, botanist and natural history artist. Life Selby was born in Bondgate Street in Alnwick in Northumberland, the eldest son of George Selby of Beal and Twizell (d.1804), and his wife, Margaret Cook. He was educated at Durham School. He studied at University College, Oxford. He succeeded in 1804 to the family estates at Beal, and added to the landholdings there at a cost of some £14000 in about 1840. He sold the Beal estate amounting to in 1850 for £47000 (£ at today's prices). He died at Twizell House and was buried in Bamburgh churchyard.

Poliocephalus Rufopectus
The New Zealand grebe (''Poliocephalus rufopectus''), also known as the New Zealand dabchick or weweia, is a member of the grebe family endemic to New Zealand. Description The New Zealand grebe has dark brown plumage, a small black head with fine silver feathers, a black pointed bill and characteristic yellow eyes. It grows to about 29 cm, and weigh about 250 g. Non-breeding individuals have a paler plumage and females tend to be a bit lighter, smaller and have a slightly shorter bill than males. Distribution and habitat This grebe species inhabits mainly shallow freshwater lakes, ponds and sheltered inlets. Currently it is found mainly in the North Island, where it is well distributed on the coastal lakes of the West coast from North Cape to Pukekohe and from Taranaki to Paraparaumu, as well as on ponds of the Volcanic Plateau, Gisborne, Hawkes bay and the Wairarapa. Formerly this species was also present in the lowland lakes of the South Island,Andrew Crowe, ''"Which ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
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 ...

Grebe
Grebes () are aquatic diving birds in the order Podicipediformes . Grebes are widely distributed freshwater birds, with some species also found in marine habitats during migration and winter. Some flightless species exist as well, most notably in stable lakes. The order contains a single family, the Podicipedidae, which includes 22 species in six extant genera. Although, superficially, they resemble other diving birds such as loons and coots, they are most closely related to flamingos, as supported by morphological, molecular and paleontological data. Many species are monogamous and are known for their courtship displays, with the pair performing synchronized dances across the water's surface. The birds build floating vegetative nests where they lay several eggs. About a third of the world's grebes are listed at various levels of conservation concerns—the biggest threats including habitat loss, the introduction of invasive predatory fish and human poaching. As such, three spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...
