Knob-billed Fruit Dove
The knob-billed fruit dove (''Ptilinopus insolitus'') is a species of bird in the family Columbidae. It is endemic to the Bismarck Archipelago. Taxonomy and systematics The knob-billed fruit dove was originally described as ''Ptilopus insolitus'' by Hermann Schlegel in 1863 on the basis of specimens from New Ireland. The name of the genus was later emended to '' Ptilinopus''. The generic name ''Ptilinopus'' is derived from the Ancient Greek words πτιλον (''ptilon''), meaning feather, and πους (''pous''), meaning foot. The specific name ''insolitus'' is from the Latin word ''insolitus'', meaning strange. Knob-billed fruit dove is the official common name designated by the International Ornithologists' Union. Other common names for the species include knob billed fruit dove, knob-billed fruit-dove, red-knobbed fruit dove, red-knobbed fruit-dove, and Schlegel's fruit-dove. The knob-billed fruit dove is closely related to the orange-bellied fruit dove, and these two spe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the natural history museum of Leiden, who was seeking an assistant. At first Schlegel worked mainly o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Birds Of The Bismarck Archipelago
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. Birds ...

Emirau Island
Emirau Island, also called Emira, is an island in the Bismarck Archipelago located at . It is currently part of the New Ireland Province of Papua New Guinea. The local language is a dialect of the Mussau-Emira language. Emira is part of what on many maps are charted as the St Matthias Islands, also known as the Mussau Islands, a small group to the north-west of the main-island group of New Ireland. Early explorers named it Squally Island, a name still found in some early records. History World War II Early in World War II this small island became international news when over 500 prisoners from various ships (including RMS ''Rangitane'') sunk by German surface raiders were released following the first attack on Nauru and subsequently rescued by the Australian authorities. Emirau was seized unopposed by two battalions of the United States 4th Marine Division on 20 March 1944.

Ernst Hartert
Ernst Johann Otto Hartert (29 October 1859 – 11 November 1933) was a widely published German ornithologist. Life and career Hartert was born in Hamburg, Germany on 29 October 1859. In July 1891, he married the illustrator Claudia Bernadine Elisabeth Hartert in Frankfurt am Main, Germany, with whom he had a son named Joachim Karl (Charles) Hartert, (1893–1916), who was killed as an English soldier on the Somme. Together with his wife, he was the first to describe the blue-tailed Buffon hummingbird subspecies (''Chalybura buffonii intermedia'' Hartert, E & Hartert, C, 1894). The article ''On a collection of Humming Birds from Ecuador and Mexico'' appears to be their only joint publication. Hartert was employed by Walter Rothschild, 2nd Baron Rothschild as ornithological curator of Rothshild's private Natural History Museum at Tring, in England from 1892 to 1929. Hartert published the quarterly museum periodical ''Novitates Zoologicae'' (1894–39) with Rothschild, and the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cline (biology)
In biology, a cline (from the Greek κλίνειν ''klinein'', meaning "to lean") is a measurable gradient in a single character (or biological trait) of a species across its geographical range. First coined by Julian Huxley in 1938, the "character" of the cline referred to is usually genetic (e.g. allele frequency, blood type), or phenotypic (e.g. body size, skin pigmentation). Clines can show smooth, continuous gradation in a character, or they may show more abrupt changes in the trait from one geographic region to the next. A cline refers to a spatial gradient in a specific, singular trait, rather than a collection of traits; a single population can therefore have as many clines as it has traits, at least in principle. Additionally, Huxley recognised that these multiple independent clines may not act in concordance with each other. For example, it has been observed that in Australia, birds generally become smaller the further towards the north of the country they are found ...

Dwarf Fruit Dove
The dwarf fruit dove (''Ptilinopus nainus'') is a species of bird in the family Columbidae. It is found in lowland and foothill forest in New Guinea and the Raja Ampat Islands.The dwarf fruit dove weighs 49 grams, about equivalent to the weight of two AA batteries This bird is the smallest of the fruit dove genus Description With a total length of 13–15 cm (5.1–5.9 in), it is the shortest pigeon or dove in the world, but as it is thickset, several other species weigh less. Its plumage is overall green, but with contrasting yellow undertail-coverts A covert feather or tectrix on a bird is one of a set of feathers, called coverts (or ''tectrices''), which, as the name implies, cover other feathers. The coverts help to smooth airflow over the wings and tail. Ear coverts The ear coverts are sm ..., and narrow bars to the wings.

Black-naped Fruit Dove
The black-naped fruit dove (''Ptilinopus melanospilus''), also known as the black-headed fruit dove, is a medium-sized, up to long, green fruit dove with yellowish bill and iris. The male has a pale grey head with a black nape, yellow throat, and golden yellow and pink undertail coverts. The plumage of the female and the young is entirely green. Distribution and habitat The black-naped fruit dove is distributed in Indonesia, Malaysia and the Philippines.

Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex.
