Drepanornis
''Drepanornis'' is a genus of bird-of-paradise found in forests of New Guinea. They have long decurved sickle-like bills and an overall brown plumage. The genus is sometimes considered a subgenus of ''Epimachus'', but the two members of ''Drepanornis'' have a far shorter tail and their sexual dimorphism is less extreme.

Black-billed Sicklebill
The black-billed sicklebill (''Drepanornis albertisi''), also known as the buff-tailed sicklebill (leading to easy confusion with the hummingbird of the same name), is a species of bird-of-paradise. It, along with its congener, are the only members of the genus ''Drepanornis.'' Conservation status Widespread throughout its large range, the black-billed sicklebill is evaluated as being of least concern on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES. Etymology The generic name ''Drepanornis'' consists of the words ''Drepane'' for "sickle" and ''ornis'' for "bird", so the genus name literally means "sickle bird", referring to their sickle-shaped bill; the specific name commemorates the Italian naturalist Luigi Maria d'Albertis, who discovered this species in 1872. The race ''cervinicauda'' subspecific name consists of ''cervinus'' for "stag-colored" and "''cauda"'' for tail, ''geisleri'' honors Bruno Geisler, a German ornithologist who described th ...

Bird-of-paradise
The birds-of-paradise are members of the family Paradisaeidae of the order Passeriformes. The majority of species are found in eastern Indonesia, Papua New Guinea and eastern Australia. The family has 44 species in 17 genera. The members of this family are perhaps best known for the plumage of the males of the species, the majority of which are sexually dimorphic. The males of these species tend to have very long, elaborate feathers extending from the beak, wings, tail or head. For the most part they are confined to dense rainforest habitat. The diet of all species is dominated by fruit and to a lesser extent arthropods. The birds-of-paradise have a variety of breeding systems, ranging from monogamy to lek-type polygamy. A number of species are threatened by hunting and habitat loss. Taxonomy The family Paradisaeidae was introduced (as Paradiseidae) in 1825 with ''Paradisaea'' as the type genus by the English naturalist William John Swainson. For many years the birds-of-pa ...

Pale-billed Sicklebill
The pale-billed sicklebill (''Drepanornis bruijnii'') is a species of sicklebill that belongs to the family Paradisaeidae, which contains the birds-of-paradise. Etymology The scientific nomenclature, or name, of this species is ''Drepanornis bruijni,'' consisting of "Drepanornis", which means "sickle bird", that refers to the birds' sickle-shaped bill, and ''bruijni'', which commemorates Antonie Augustus Bruijn, a Dutch plume merchant. Description Pale-billed sicklebills are on the more medium-sized side of the family Paradisaeidae; they seldom reach over 35 cm, or 13.7 inches, in length. They are among the least attractive birds-of-paradise, being a dull brownish-olive on their upperside, with a greyish-brown underside. Their heads are dark brown, and one of their most noticeable features are lead-grey bare facial patches surrounding each eye and covering most of the head; there are also two iridescent tufts rising above the head. Unlike their congener's bill, they h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Epimachus
''Epimachus'' is a genus of birds-of-paradise (Paradisaeidae) that includes two species, found in the highland forests of New Guinea. They are the largest members of the family. The common name "sicklebill" refers to their long, decurved, sickle-shaped bill. Sicklebills often associate with astrapias, which are superficially similar but have a short, straight bill and blunt-tipped tail, and the male's wings hiss in flight. The species in the genus ''Epimachus'' are often referred to as "long-tailed" sicklebills, when describing them collectively as a genus. The other sicklebills, genus '' Drepanornis'', are referred to as the "short-tailed" sicklebills. Ironically, the two genera are not closely related. There may also be confusion with the birds of the same name that belong to the hummingbird family, found in the Americas. Taxonomy The genus ''Epimachus'' was introduced in 1816 by the French naturalist Georges Cuvier for the black sicklebill. The genus name is from the ...

Philip Lutley Sclater
Philip Lutley Sclater (4 November 1829 – 27 June 1913) was an English lawyer and zoologist. In zoology, he was an expert ornithologist, and identified the main zoogeographic regions of the world. He was Secretary of the Zoological Society of London for 42 years, from 1860–1902. Early life Sclater was born at Tangier Park, in Wootton St Lawrence, Hampshire, where his father William Lutley Sclater had a country house. George Sclater-Booth, 1st Baron Basing was Philip's elder brother. Philip grew up at Hoddington House where he took an early interest in birds. He was educated in school at Twyford and at thirteen went to Winchester College and later Corpus Christi College, Oxford where he studied scientific ornithology under Hugh Edwin Strickland. In 1851 he began to study law and was admitted a Fellow of Corpus Christi College. In 1856 he travelled to America and visited Lake Superior and the upper St. Croix River, canoeing down it to the Mississippi. Sclater wrote ab ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Sickle
A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting, or reaping, grain crops or cutting succulent forage chiefly for feeding livestock, either freshly cut or dried as hay. Falx was a synonym but was later used to mean any of a number of tools that had a curved blade that was sharp on the inside edge such as a scythe. Since the beginning of the Iron Age hundreds of region-specific variants of the sickle have evolved, initially of iron and later steel. This great diversity of sickle types across many cultures can be divided into smooth or serrated blades, both of which can be used for cutting either green grass or mature cereals using slightly different techniques. The serrated blade that originated in prehistoric sickles still dominates in the reaping of grain and is even found in modern grain-harvesting machines and in some kitchen knives.

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 eating, preening, manipulating objects, killing prey, fighting, probing for food, 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, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-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 word "beak" was, in the past, generally restricted to the sharpened bills o ...

Plumage
Plumage ( "feather") is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morphs. The placement of feathers on a bird is not haphazard, but rather emerge in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month or so l ...

Sexual Dimorphism
Sexual dimorphism is the condition where the sexes of the same animal and/or plant species exhibit different morphological characteristics, particularly characteristics not directly involved in reproduction. The condition occurs in most animals and some plants. Differences may include secondary sex characteristics, size, weight, colour, markings, or behavioural or cognitive traits. These differences may be subtle or exaggerated and may be subjected to sexual selection and natural selection. The opposite of dimorphism is ''monomorphism'', which is when both biological sexes are phenotypically indistinguishable from each other. Overview Ornamentation and coloration Common and easily identified types of dimorphism consist of ornamentation and coloration, though not always apparent. A difference in coloration of sexes within a given species is called sexual dichromatism, which is commonly seen in many species of birds and reptiles. Sexual selection leads to the exaggerated dim ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
