Astrapia is a taxonomic genus of birds-of-paradise (Paradisaeidae). 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.

The astrapian sicklebill, also known as the green-breasted riflebird, is a bird in the Paradisaeidae family that is believed to be an intergeneric hybrid between an Arfak astrapia and black sicklebill. This explanation was proposed by Erwin Stresemann who used the same explanation for the Elliot's bird-of-paradise. The two forms are substantially different and the latter's validity is still under question.

Bensbach's bird-of-paradise, also known as Bensbach's riflebird, is a bird in the family Paradisaeidae that is often now considered an intergeneric hybrid between a magnificent riflebird and lesser bird-of-paradise. However, some authors, such as Errol Fuller, believe that it was a distinct and possibly extinct species.

The common name commemorates Maarten Dirk van Renesse van Duivenbode (1804–1878), Dutch trader of naturalia on Ternate.

Elliot's bird of paradise is a bird in the family Paradisaeidae that is presumed to be an intergeneric hybrid between a black sicklebill and Arfak astrapia. This assumption was made by Erwin Stresemann who had also dismissed other new species of birds of paradise as hybrids. A minority of ornithologists dispute this claim; specimens are considerably smaller than the latter two species. Additionally, Stresemann used the A. nigra x E. fastuosus explanation for the astrapian sicklebill as well. It was first described by Edward Ward in 1873.
