Birds of Paradise hybrids – Astrapian Sicklebill

The exceedingly beautiful Astrapian Sicklebill is known from exactly one single specimen.

The form, also known as Green-breasted Riflebird, was described as a good species in 1897, it is however, a hybrid form with the Arfak Astrapia (Astrapia nigra (J. F. Gmelin)) and the Black Sicklebill (Epimachus fastuosus (Hermann)) being the parent species.

It is somewhat strange that the same species are thought to be the parents of a very distinct form, Elliot’s Bird of Paradise (Epimachus elliotti Ward).

Birds of Paradise hybrides – Duivenbode’s Six-wired Bird of Paradise

At first sight this bird looks quite like a typical parotia, bearing a glossy breast shield and elongated, thread-like occipital plumes, however, it only had two of them instead of the usual six, so its vernacular name Duivenbode’s Six-wired Bird of Paradise should actually rather be Duivenbode’s Two-wired Bird of Paradise.

The form is known from two male specimens and is now known to be a hybrid of the Superb Bird of Paradise (Lophorina superba (J. R. Forster)) and the Western Parotia (Parotia sefilata (Pennant)).

Birds of Paradise hybrids – Le Nébuleux

This might be the first part of a little series ….

Le Nébuleux, or the Nebulous, is known only from two paintings by Jacques Barraband in François Le Vaillant’s ‚Histoire naturelle des oiseaux de paradis et des rolliers‘ from 1806, which very likely show a single specimen in two different positions. Jacques Barraband is known to have been absolutely accurate, thus the bird he depicted must have existed and must have looked like in his depictions. [1]

The specimen is very clearly a Twelfe-wired Bird of Paradise (Seleucides melanoleuca (Daudin)) but with only nine (or then?) instead of twelfe ‚wires‘ and with the underparts being black instead of yellow; its female-like brown colored wings indicate that it was a subadult bird. [2]

The Nebulous may have been the same as Bruijn’s Riflebird (Craspedophora bruyni Büttikofer) aka Mantou’s Riflebird (Craspedophora mantoui Oustalet), which both are hybrids of the Magnificent Riflebird (Ptiloris magnificus Vieillot) and the actual Twelfe-wired Bird of Paradise. [2]
