Yellow-breasted Bowerbird
The yellow-breasted bowerbird (''Chlamydera lauterbachi'') also known as Lauterbach's bowerbird, is a medium-sized, approximately 27 cm long, bowerbird with a brownish-olive upperparts plumage, grayish-yellow upper breast, coppery crown, dark brown iris, yellow underparts, a black bill and pinkish-orange mouth. Both sexes are similar. The female exhibits less vibrant coloration than the male. Habitat The yellow-breasted bowerbird is distributed on mainland New Guinea, where it inhabits grasslands, lowlands, and subtropical mountain forests. Its diet mainly consists of fruits, caterpillars, beetles, and other insects. The nest is a shallow cup made of small sticks located in a tree. The bower itself is of the "avenue" type, with four walls made of sticks and an outward-angled main avenue wall. The scientific name commemorates its discoverer, the German botanist Carl Lauterbach. He discovered this bowerbird in 1896. Widespread and a common species throughout its habitat r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anton Reichenow
Anton Reichenow (1 August 1847 in Charlottenburg – 6 July 1941 in Hamburg) was a German ornithologist and Herpetology, herpetologist. Reichenow was the son-in-law of Jean Cabanis, and worked at the Natural History Museum, Berlin, Natural History Museum of Berlin from 1874 to 1921. He was an expert on African birds, making a collecting expedition to West Africa in 1872 and 1873, and writing ''Die Vögel Afrikas'' (1900–05). He was also an expert on parrots, describing all species then known in his book ''Vogelbilder aus Fernen Zonen: Abbildungen und Beschreibungen der Papageien'' (illustrated by Gustav Mützel, 1839–1893).

Bowerbird
Bowerbirds () make up the bird family Ptilonorhynchidae. They are renowned for their unique courtship behaviour, where males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate. The family has 27 species in eight genera. These are medium to large-sized passerines, ranging from the golden bowerbird at and to the great bowerbird at and . Their diet consists mainly of fruit but may also include insects (especially for nestlings), flowers, nectar and leaves in some species. The satin and spotted bowerbirds are sometimes considered agricultural pests due to their habit of feeding on introduced fruit and vegetable crops and have occasionally been killed by affected orchardists. The bowerbirds have an Australo-Papuan distribution, with ten species endemic to New Guinea, eight endemic to Australia, and two found in both. Although their distribution is centered on the tropical regions of New Guinea and northern Australia, som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iris (anatomy)
The iris (: irides or irises) is a thin, annular structure in the eye in most mammals and birds that is responsible for controlling the diameter and size of the pupil, and thus the amount of light reaching the retina. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm (optics), diaphragm. Eye color is defined by the iris. Etymology The word "iris" is derived from the Greek word for "rainbow", also Iris (mythology), its goddess plus messenger of the gods in the ''Iliad'', because of the many eye color, colours of this eye part. Structure The iris consists of two layers: the front pigmented Wikt:fibrovascular, fibrovascular layer known as a stroma of iris, stroma and, behind the stroma, pigmented epithelial cells. The stroma is connected to a sphincter muscle (sphincter pupillae), which contracts the pupil in a circular motion, and a set of dilator muscles (dilator pupillae), which pull the iris radially to enlarge the pupil, pulling it in folds. ...

Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for pecking, grasping, and holding (in probing for food, eating, manipulating and carrying objects, killing prey, or fighting), preening, courtship, and feeding young. The terms ''beak'' and '' rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, rhynchosaurs, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a bill-like structure), sirens, pufferfish, billfishes, and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections–the upper and lower mandibles–are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Guinea
New Guinea (; Hiri Motu: ''Niu Gini''; , fossilized , also known as Papua or historically ) is the List of islands by area, world's second-largest island, with an area of . Located in Melanesia in the southwestern Pacific Ocean, the island is separated from Mainland Australia, Australia by the wide Torres Strait, though both landmasses lie on the same continental shelf, and were united during episodes of low sea level in the Pleistocene glaciations as the combined landmass of Sahul. Numerous smaller islands are located to the west and east. The island's name was given by Spanish explorer Yñigo Ortiz de Retez during his maritime expedition of 1545 due to the perceived resemblance of the indigenous peoples of the island to those in the Guinea (region), African region of Guinea. The eastern half of the island is the major land mass of the nation of Papua New Guinea. The western half, known as Western New Guinea, forms a part of Indonesia and is organized as the provinces of Pap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

Chlamydera
''Chlamydera'' is a genus of passerine birds in the bowerbird family Ptilonorhynchidae that are found in Australia and New Guinea. The birds in this genus build "avenue-type" bowers which consist of two parallel walls made of vertical sticks and pieces of grass. Taxonomy The genus ''Chlamydera'' was introduced in 1837 by the English ornithologist John Gould to accommodate ''Calodera maculata'' Gould, the spotted bowerbird, which is therefore the type species by monotypy. The genus name combines the Ancient Greek χλαμυς/''khlamus'' meaning "short cloak" with δερα/''dera'' meaning "neck". Species The genus contains five species: * Fawn-breasted bowerbird (''Chlamydera cerviniventris'') * Western bowerbird (''Chlamydera guttata'') * Great bowerbird (''Chlamydera nuchalis'') * Yellow-breasted bowerbird (''Chlamydera lauterbachi'') * Spotted bowerbird The spotted bowerbird (''Chlamydera maculata'') is a sedentary, mid-sized passerine found across broad parts of the d ...

Birds Of New Guinea
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings 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 Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
