The Black Sicklebill, Epimachus fastuosus, is a large bird of paradise that occurs naturally in the midmountain forests of New Guinea (situated to the north of Australia in the southwest Pacific Ocean).

The male has black plumage with an iridescent green, blue and purple scale-like feathers, red iris, bright yellow mouth, long curved black bill, huge sabre-shaped tail and large erectile fan-like plumes on sides of breast. The female is smaller than the male. It has a reddish brown plumage with brown iris and buff below.

the male Black Sicklebill is the longest member of Paradisaeidae With up to 110 cm in length and the females about 48 cm. The female is smaller than the male. Her plumage is mostly reddish-brown, with chestnut wing-feather fringes and fine, dark brown barring on her off-white underparts. Her eyes are red-brown.

The diet consists mainly of fruits and arthropods. The male is polygamous and performs a horizontal courtship display with the pectoral plumes raised around its head.

This species is listed as Vulnerable based on an estimated small population which is believed to be declining due to hunting for food or the long plumes of the males, which are used in traditional head-dresses. Other risks to their continued existence are a growing human population and conversion of their natural habitat for agricultural uses or forest losses due to logging. This species is intolerant of secondary forests caused by shifting agriculture and logging. The Black Sicklebill is classified as Vulnerable on the IUCN Red List of Threatened Species and is listed on Appendix II of CITES.
