Peltops
''Peltops'' is a genus of birds in the family Artamidae. It contains two species that are endemic to the island of New Guinea. The species have also had the common name of shieldbill. Taxonomy The genus ''Peltops'' was introduced by the German zoologist Johann Georg Wagler in 1829. The type species is the lowland peltops. The name is from the Greek ''pelte'' meaning small shield and ''ops'' meaning face. The genus was once placed with the monarch flycatchers, but molecular and morphometric studies place it closer to the butcherbirds, possibly as a sister taxon to this group. The genus is placed in its own subfamily, Peltopsinae. The genus contains two species: Description ''Peltops'' are smaller than the butcherbirds, and have a less massive but still large bill. The mountain peltops is the larger species, at , whereas the lowland peltops is slightly smaller at . The hooked bill is the same size in both species, making it proportionally larger in the lowland peltops. Distrib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artamidae
Artamidae is a family of passerine birds found in Australia, the Indo-Pacific region, and Southern Asia. It includes 24 extant species in six genera and three subfamilies: Peltopsinae (with one genus, '' Peltops''), Artaminae (with one genus containing the woodswallows) and Cracticinae ( currawongs and butcherbirds, including the Australian magpie). Artamids used to be monotypic, containing only the woodswallows, but it was expanded to include the family Cracticidae in 1994. Some authors, however, still treat the two as separate families. Some species in this family are known for their beautiful song. Their feeding habits vary from nectar sucking (woodswallows) to predation on small birds (pied currawong). Taxonomy and systematics The family Artamidae was introduced by the Irish zoologist Nicholas Aylward Vigors in 1825. The artamids are part of the superfamily Malaconotoidea, a lineage which is widespread through Australasia and consists of a vast diversity of omnivorous a ...

Cracticidae
The Cracticinae, bellmagpies and allies, gathers together 12 species of mostly crow-like birds native to Australasia and nearby areas. Historically, the cracticines – currawongs, Australian magpie and butcherbirds – were seen as a separate family Cracticidae and, according to the 2018 Cements List, they still are. With their 1985 DNA study, Sibley and Ahlquist recognised the close relationship between the woodswallows and the butcherbirds in 1985, and placed them in a Cracticini clade, now the family Artamidae. The two species of peltops were once placed with the monarch flycatchers but are now placed here. The cracticines have large, straight bills and mostly black, white or grey plumage. All are omnivorous to some degree: the butcherbirds mostly eat meat; Australian magpies usually forage through short grass looking for worms and other small creatures; and currawongs are true omnivores, taking fruit, grain, meat, insects, eggs and nestlings. The female constructs bulky nes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Peltops
The mountain peltops (''Peltops montanus'') is a species of bird in the family Cracticidae. It is found in Indonesia and Papua New Guinea. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical moist montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is ...s.

Bird Genera
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] |
Handbook Of The Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned sp ...

Canopy (biology)
In biology, the canopy is the aboveground portion of a plant community, plant cropping or crop, formed by the collection of individual Crown (botany), plant crowns. In forest ecology, the canopy is the upper layer or habitat zone, formed by mature tree crowns and including other biological organisms (epiphytes, lianas, Arboreal, arboreal animals, etc.). The communities that inhabit the canopy layer are thought to be involved in maintaining forest diversity, Ecological resilience, resilience, and functioning. Shade trees normally have a dense canopy that blocks light from lower growing plants. Early observations of canopies were made from the ground using binoculars or by examining fallen material. Researchers would sometimes erroneously rely on extrapolation by using more reachable samples taken from the understory. In some cases, they would use unconventional methods such as chairs suspended on vines or hot-air dirigibles, among others. Modern technology, including adapted ...

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] |
Butcherbird
Butcherbirds are songbirds closely related to the Australian magpie. Most are found in the genus ''Cracticus'', but the black butcherbird is placed in the monotypic genus ''Melloria''. They are native to Australasia. Taxonomy Together with three species of currawong and two species of peltops, butcherbirds and the Australian magpie form the subfamily Cracticinae in the family Artamidae. (Despite the name of the Australian magpie, this family of birds is not closely related to European magpies, which are members of the family Corvidae.) Description Butcherbirds are large songbirds, being between in length. Their colour ranges from black-and-white to mostly black with added grey plumage, depending on the species. They have a large, straight bill with a distinctive hook at the end which is used to skewer prey. They have high-pitched complex songs, which are used to defend their essentially year-round group territories: unlike birds of extratropical Eurasia and the Americas, both ...
