Astrapia (Vieillot, 1816) is a genus of birds-of-paradise. The genus contains five species, all endemic to New Guinea. The males have highly iridescent plumage and remarkably long tails. Females are duller and have shorter tails.

Barnes's astrapia is a hybrid produced by the interbreeding of Princess Stephanie's astrapia and the ribbon-tailed astrapia. [1]

Taxonomy

The genus Astrapia was introduced in 1816 by the French ornithologist Louis Pierre Vieillot to accommodate the Arfak astrapia, which therefore becomes the type species. [2] [3] The genus name is derived from Ancient Greek astrapios or astrapaios meaning "of lightning". [4]

The genus is suggested to be monophyletic, roughly six million years old, and forms a sister-group with the two species in the genus Paradigalla . [5] Astrapia and Paradigalla are members of a larger clade that includes the other long-tail birds-of-paradise from the genus Epimachus . [6]

Species

The genus contains five species: [7]

Within the genus, A. nigra and A. splendidissima are sister species, which together are sister to a clade that includes A. rothschildi, A. mayeri and A. stephaniae with A. rothschildi as the basal member. [8]

Ribbon-tailed Astrapia, Papua New Guinea

The five species of the genus Astrapia are endemic to New Guinea in the mountains of Volgelkop, the central ranges and the Huon Peninsula. Of these, three are allopatricA. nigra, A. splendidissima and A. rothschildi. The other two—A. mayeri and A. stephaniae—overlap with each other at the margins of their respective elevation ranges in a small part of Papua New Guinea's central highlands. [1] [5]

All species within Astrapia exhibit sexual dimorphism. Adult males appear mostly jet-black under most lighting conditions, with highly iridescent greenish-blue heads, an intensely reflective coppery-orange band on the upper breast and either a deep violet (nearly black) or mostly white tail. [6] The three allopatric species also have iridescent green lower abdomen. Adult females are duller blackish-brown, with smaller, white smudged tails running down their lengths. [9]

Behavior

Mating and breeding

Breeding behaviors are not well known, but all species are thought to be polygamous, with promiscuous males that use arboreal display sites, and with females providing all parental care. [9] Summaries from species accounts indicate a few simple behaviors including a form of hoping back and forth between branches and an inverted display posture in A. rothschildi. [6] At traditional sites in the forest canopy, Astrapia stephaniae is known to form leks. [6] [10]

There are seven distinct male courtship displays that have been documented: perch-hopping, pivoting, inverted tail-fanning, nape-pecking, post-copulatory tumbling, upright sleeked posturing and branch-sidling. [6] Of the male behaviors, perch-hopping is the most broadly distributed among all species but A. nigra. In all of them, the displaying bird moves quickly between multiple branches by hopping or making short flight-hops. In A. rothschildi, hopping between perches sometimes includes chasing females (or female plumaged individuals). It is unclear if chasing is a component of perch-hopping in the other species. [6]

A type of pivot display is known from two species, A. rothschildi and A. mayeri . In both, it involves repeatedly moving in a ritualized fashion from side-to-side with feet more-or-less in a fixed position. The most distinctive feature of the A. rothschildi pivot is wing flicking, whereas in A. mayeri the most distinctive features are the very ritualized hunchbacked posture and the highly exaggerated swishing movement of the male's long ribbon-like tail. [6]

The Arfak astrapia and the Huon astrapia have a distinctive and specialized display behavior, which is called the inverted tail-fan display. When the abdominal feathers are sky-oriented during the display, their green iridescent feathers (that would appear otherwise dark) become highly visible; the splendid astrapia also has highly iridescent green abdominal plumage, which raises the question about if it too has an undocumented inverted display behavior.

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 45 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 habitats. 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.

The satinbirds or cnemophilines, are a family, Cnemophilidae of passerine birds which consists of four species found in the mountain forests of New Guinea. They were originally thought to be part of the birds-of-paradise family Paradisaeidae until genetic research suggested that the birds are not closely related to birds-of-paradise at all and are perhaps closer to berry peckers and longbills (Melanocharitidae). The current evidence suggests that their closest relatives may be the cuckoo-shrikes (Campephagidae).

<span class="mw-page-title-main">Elliot's bird-of-paradise</span> Hybrid bird

Elliot's bird of paradise is a bird in the family Paradisaeidae, first described by Edward Ward in 1873. The bird is presumed by some ornithologists to be an intergeneric hybrid between a black sicklebill and Arfak astrapia. This assumption was made by the German ornithologist Erwin Stresemann who had also dismissed other new species of birds of paradise as hybrids. Other ornithologists dispute this claim. Errol Fuller argues that the Astrapia is a fanciful choice made with little supporting evidence, and that Elliot's Bird of Paradise is much smaller than the two proposed parent species. The specimens show a number of characteristics not present in either parent species, adding weight to the possibility of the specimens constituting a unique species. Stresemann had previously used the A. nigra x E. fastuosus explanation for the astrapian sicklebill as well.
