Ducula Poliocephala
''Ducula'' is a genus of the pigeon family Columbidae, collectively known as imperial pigeons. They are large to very large pigeons with a heavy build and medium to long tails. They are arboreal, feed mainly on fruit and are closely related to the other genus of fruit-eating doves, ''Ptilinopus''. Both genera display brightly coloured plumage, predominantly green, often with contrasting under-parts of purple, orange or red. Some ''Ducula'' have prominently swollen ceres. They have large gapes and swallow seeds whole, playing an important role in seed dispersal. Imperial pigeons are found in forests of southern Asia, New Guinea, northern Australia and the Pacific islands. Many species are nomadic, travelling long distances to exploit seasonal fruit sources. Some undertake migrations and all are strong fliers. Because of habitat loss and predation, species of ''Ducula'' are amongst the most threatened of avian species globally.

Ducula Perspicillata
The spectacled imperial pigeon (''Ducula perspicillata'') is a species of bird in the family Columbidae. It is endemic to the Maluku Islands. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest, especially recently disturbed forests. Taxonomy and systematics The spectacled imperial pigeon is a species in the large genus of imperial pigeons, '' Ducula''. Within the genus, it is most closely related to the Seram imperial pigeon, with which it is sometimes considered conspecific. These two species form a species group with the green imperial pigeon and elegant imperial pigeon.

Ducula Nicobarica
The Nicobar imperial pigeon (''Ducula nicobarica'') is a species of bird in the family Columbidae. It is endemic to the Nicobar Islands. Its natural habitats are lowland forests, but it also feeds on fruiting trees in agricultural landscapes. This species was formerly treated as subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morpholog ... of the green imperial pigeon (''Ducula aenea''). It is now considered as a separate species based on the big differences in both plumage and vocalization compared to all other green imperial pigeon subspecies.

Ducula Aenea
The green imperial pigeon (''Ducula aenea'') is a large forest pigeon. The large range extends from Nepal, southern India and Sri Lanka eastwards to southern China, Indonesia and the Philippines. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the green imperial pigeon in his six volume ''Ornithologie''. He used the French name ''Le pigeon ramier des Moluques'' and the Latin ''Palumbus moluccensis''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the green imperial pigeon which he placed with all the other pig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Green Imperial Pigeon RWD5a
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while r ...

Ducula Carola
The spotted imperial pigeon (''Ducula carola''), also known as the grey-necked imperial pigeon, is a species of bird in the family Columbidae. This species is endemic to the Philippines. Its natural habitat is tropical moist lowland forests and tropical moist montane forest but seasonally migrates to limestone shorelines in large flocks of up to 50 individuals, for still unknown and not-well studied reasons but the prevailing theories is that it feeds on the calcium deposits.. Among the imperial pigeons of the Philippines, this species is the most threatened - assessed as a Vulnerable species with population estimates of 1,200 to 3,200 mature individuals and still believed to be on the decline due to habitat loss, hunting and capture for the illegal wildlife trade. It is illegal to hunt, capture or possess spotted imperial pigeons under Philippine Law RA 9147.
