This article is about the bird family Paradisaeidae. For other uses, see Bird of paradise (disambiguation).
The birds of paradise are members of the family Paradisaeidae of the order Passeriformes. They are found in eastern Indonesia, Torres Strait Islands, Papua New Guinea, and eastern Australia. The members of this family are perhaps best known for the plumage of the males of most species, in particular highly elongated and elaborate feathers extending from the beak, wings or head. Birds of paradise range in size from the King Bird of Paradise at 50 grams (1.8 oz) and 15 cm (6 in) to the Black Sicklebill at 110 cm (43 in) and the Curl-crested Manucode at 430 grams (15.2 oz). Best known are the members of the genus Paradisaea, including the type species, the Greater Bird of Paradise, Paradisaea apoda. This species was described from specimens brought back to Europe from trading expeditions.[when?] These specimens had been prepared by native traders by removing their wings and feet so that they could be used as decorations. This was not known to the explorers and led to the belief that the birds never landed but were kept permanently aloft by their plumes. This is the origin of both the name "birds of paradise" and the specific name apoda — without feet.[citation needed]
[edit] BiologyBirds of paradise are generally crow-like in general body-form, and, indeed are the brother group to the Corvids (crows and jays). They have stout or long bills and strong feet, with around two-thirds of the species being strongly sexually dimorphic. They live in tropical forests, including rainforest, swamps and moss forest. In most species, the diet consists predominantly of fruit, although riflebirds and sicklebills also favour insects and other arthropods.[1] Most species have elaborate mating rituals, with the Paradisaea species using a lek-type mating system. Others, such as the Cicinnurus and Parotia species, have highly ritualised mating dances. Males are polygamous in the sexually dimorphic species, but monogamous in at least some of the monomorphic species. Hybridisation is frequent in these birds, suggesting the polygamous species of bird of paradise are very closely related despite being in different genera. Many hybrids have been described as new species, and doubt remains regarding whether some forms, such as Rothschild's Lobe-billed Bird of Paradise, are valid.[citation needed] Despite the presence of hybrids, some ornithologists hypothesise that at least some putative hybrids are valid species that may be extinct.[2] Birds of paradise build their nests from soft materials, such as leaves, ferns, and vine tendrils, typically placed in a tree fork.[1] Clutch size is somewhat uncertain. In the large species, it is almost always just one egg. Smaller species may produce clutches of 2-3.[3] Eggs hatch after 16–22 days, and the young leave the nest at between 16 and 30 days of age.[1] The manucodes are the most primitive members of the group.[citation needed] [edit] Species
[edit] HybridsHybrid birds of paradise may occur when individuals of different species, that look similar and have overlapping ranges, confuse each other for their own species and crossbreed. When Erwin Stresemann realised that hybridisation among birds of paradise might be an explanation as to why so many of the described species were so rare, he examinined many controversial specimens and, during the 1920s and 1930s, published several papers on his hypothesis. Many of the species described in the late 19th and early 20th centuries are now generally considered to be hybrids, though some are still subject to dispute; their status is not likely to be settled definitely without genetic examination of museum specimens. Some named hybrids and presumed hybrids are:[4]

[edit] Relationship with humansSocieties of New Guinea often use bird of paradise plumes in their dress and rituals, and the plumes were popular in Europe in past centuries as adornment for ladies' millinery. Hunting for plumes and habitat destruction have reduced some species to endangered status; habitat destruction due to deforestation is now the predominant threat.[citation needed] [edit] HuntingHunting of birds of paradise has occurred for a long time, possibly since the beginning of human settlement. It is a peculiarity that among the most frequently-hunted species, males start mating opportunistically even before they grow their ornamental plumage. This may be an adaptation maintaining population levels in the face of hunting pressures, which have probably been present for 30 millennia.[citation needed] Hunting birds of paradise for their plumes for the millinery trade was extensive in the late 19th and early 20th century[6], but today the birds enjoy legal protection and hunting is only permitted at a sustainable level to fulfill the ceremonial needs of the local tribal population. In the case of Pteridophora plumes, scavenging from old bowerbird bowers is encouraged. When King Mahendra of Nepal was crowned in 1955, it was found that the bird of paradise plumes of the Nepali royal crown were in need of replacement. Due to the hunting ban, replacements were eventually procured from a confiscated shipment seized by the United States Customs Service.[citation needed] [edit] Other examples
