Tricolored Grebe
The tricolored grebe (''Tachybaptus tricolor'') is a bird in the family Podicipedidae sometimes considered conspecific with the little grebe (''Tachybaptus ruficollis''). It is native to maritime Southeast Asia and Australasia. The IOC has split the bird; however, other taxonomic authorities still consider the birds conspecific. Systematics The following subspecies are considered to be part of the ''tricolor'' group: *''Tachybaptus ruficollis vulcanorum'' ( Rensch, 1929): Sulawesi, North Maluku to New Guinea *''Tachybaptus ruficollis tricolor'' (Gray, 1861): Java, Timor, Lesser Sundas, northeast New Guinea to Bougainville Island. *''Tachybaptus ruficollis collaris'' (Mayr, 1945): Solomon Islands Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capita ... References Podicipedidae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Robert Gray

Java
Java (; id, Jawa, ; jv, ꦗꦮ; su, ) is one of the Greater Sunda Islands in Indonesia. It is bordered by the Indian Ocean to the south and the Java Sea to the north. With a population of 151.6 million people, Java is the world's List of islands by population, most populous island, home to approximately 56% of the Demographics of Indonesia, Indonesian population. Indonesia's capital city, Jakarta, is on Java's northwestern coast. Many of the best known events in Indonesian history took place on Java. It was the centre of powerful Hindu-Buddhist empires, the Islamic sultanates, and the core of the colonial Dutch East Indies. Java was also the center of the History of Indonesia, Indonesian struggle for independence during the 1930s and 1940s. Java dominates Indonesia politically, economically and culturally. Four of Indonesia's eight UNESCO world heritage sites are located in Java: Ujung Kulon National Park, Borobudur Temple, Prambanan Temple, and Sangiran Early Man Site. ...

Tachybaptus
''Tachybaptus'' is a genus of small members of the grebe family birds. The genus name means "quick diving": it is from Ancient Greek ''takhys'' "quick" and ''bapto'' "I dip". It has representatives over much of the world, including the tropics. These grebes breed in small colonies in heavily vegetated areas of freshwater lakes. They may move to more open or coastal waters when not breeding, and birds in those areas where the waters freeze may be migratory. Like all grebes, they nest on the water's edge, since the legs are set very far back and they cannot walk well. The striped young are sometimes carried on the adult's back. These small grebes are excellent swimmers and divers, and pursue their fish prey underwater. The sexes are similar: dumpy and short-billed with a “powder puff” rear end. Adults have a distinctive breeding plumage and loud breeding calls. In winter, they are grey and white. The five Old World species are closely related to each and at least three have i ...

Solomon Islands
Solomon Islands is an island country consisting of six major islands and over 900 smaller islands in Oceania, to the east of Papua New Guinea and north-west of Vanuatu. It has a land area of , and a population of approx. 700,000. Its capital, Honiara, is located on the largest island, Guadalcanal. The country takes its name from the wider area of the Solomon Islands (archipelago), which is a collection of Melanesian islands that also includes the Autonomous Region of Bougainville (currently a part of Papua New Guinea), but excludes the Santa Cruz Islands. The islands have been settled since at least some time between 30,000 and 28,800 BCE, with later waves of migrants, notably the Lapita people, mixing and producing the modern indigenous Solomon Islanders population. In 1568, the Spanish navigator Álvaro de Mendaña was the first European to visit them. Though not named by Mendaña, it is believed that the islands were called ''"the Solomons"'' by those who later receiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Mayr
Ernst Walter Mayr (; 5 July 1904 – 3 February 2005) was one of the 20th century's leading evolutionary biologists. He was also a renowned Taxonomy (biology), taxonomist, tropical explorer, ornithologist, Philosophy of biology, philosopher of biology, and History of science, historian of science. His work contributed to the conceptual revolution that led to the Modern synthesis (20th century), modern evolutionary synthesis of Gregor Mendel, Mendelian genetics, systematics, and Charles Darwin, Darwinian evolution, and to the development of the Species, biological species concept. Although Charles Darwin and others posited that multiple species could evolve from a single common ancestor, the mechanism by which this occurred was not understood, creating the ''species problem''. Ernst Mayr approached the problem with a new definition for species. In his book ''Systematics and the Origin of Species'' (1942) he wrote that a species is not just a group of Morphology (biology), morph ...

Lesser Sundas
The Lesser Sunda Islands or nowadays known as Nusa Tenggara Islands ( id, Kepulauan Nusa Tenggara, formerly ) are an archipelago in Maritime Southeast Asia, north of Australia.

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 ...
