The brown sicklebill (Epimachus meyeri) is a species of bird-of-paradise that is found in the mountain forests of New Guinea.
Its appearance resembles the closely related and larger black sicklebill. In areas where these two large sicklebills met, the brown sicklebill replaced the latter species in higher altitudes. Its diet consists mainly of fruits, arthropods and small animals. The male has a staccato, burst-like call which resembles a burst of automatic gunfire.
The brown sicklebill is evaluated as Least Concern on the IUCN Red List of Threatened Species. It is listed on Appendix II of CITES.
The brown sicklebill is large, up to 96 cm long, dark blue and green with highly iridescent plumages, a sickle-shaped bill, pale blue iris and brown underparts. The male is adorned with ornamental plumes on the sides of its rear and a huge sabre-shaped central tail feathers that are highly prized by natives. The female is a reddish-brown bird with buff barred black below.
