The black-billed sicklebill, also referred to as the buff-tailed sicklebill, is a species of bird-of-paradise. It, along with its congener, are the only members of the genus Drepanornis.
Region
New Guinea
Typical Environment
Occurs in lower montane and hill rainforests across central and southeastern New Guinea, extending into adjacent foothills. Prefers dense, humid forest with rich epiphyte growth and tangled vines. Often uses edges, gaps, and secondary forest but remains tied to closed-canopy habitats. Forages from the understory to mid-storey, occasionally descending to the forest floor to probe among litter.

The black-billed sicklebill is one of only two species in the genus Drepanornis, the other being the buff-billed sicklebill. Its long, decurved bill is adapted for probing among mosses, flowers, and leaf litter in New Guinea’s rainforests. Males perform subtle display routines at dispersed courts, using posture, wing-flicks, and soft calls rather than extravagant plumes. It is sometimes called the buff-tailed sicklebill, reflecting the warm tones in the tail.
