Black Sicklebill

Epimachus fastosus

The black sicklebill, Epimachus fastosus, is a remarkable and large bird of paradise, boasting a length of approximately 110 cm including its tail, which is the second-longest among its kin. The males are adorned with jet-black plumage, iridescent scale-like feathers of a metallic blue to greenish-blue hue, and a long, silver bill. Their eyes are a striking scarlet-red, set in a face with blue-greenish iridescent feathers. The females, in contrast, are more subdued in coloration, with olive-light brown upper parts and a creamy belly with black barring.

Identification Tips

To identify the male black sicklebill, look for the long, slightly downcurved silver bill, the bright yellow mouth, and the scarlet-red eyes. The iridescent blue-greenish feathers on the face and the black body with blue iridescence are also key features. The female can be recognized by her olive-light brown upper parts, orange-brown crown, and creamy belly with black barring. Both sexes have grey-blackish legs and feet.


The black sicklebill is found in montane forests, preferring altitudes ranging from 1,800 to 2,150 meters.


This species is native to central New Guinea and the Vogelkop region to the northwest.


The black sicklebill is known to feed solitarily, although it may occasionally join mixed foraging flocks. During courtship, the male performs an elaborate display involving his pectoral fans to impress the female.

Song & Calls

The male black sicklebill produces a distinctive, powerful "kwit-it kwit-it" call that carries far and is a characteristic sound within its habitat.


Breeding males display from September to October and February to April. They are polygynous, mating with multiple females. The female is solely responsible for nest-building and caring for the offspring.

Similar Species

The black sicklebill may be confused with the brown sicklebill, but can be distinguished by the male's less downcurved bill and the female's brown eyes.

Diet and Feeding

Omnivorous in nature, the black sicklebill feeds on an equal proportion of fruits and animal prey, including insects.

Conservation status

The black sicklebill is currently classified as Least Concern by the IUCN Red List, with an estimated population of 2,000-10,000 individuals. However, it faces threats from habitat loss, hunting, and a declining population in parts of its range.

Fun way to add to your birdwatching experience
I enjoy watching birds in my backyard, but this app helped me really pay attention while on vacation this summer. It was fun to add new birds to my bird watching app.

This is a really lovely app, for everyone interested in birds - from newbies to old hands.

Learning Birding with Birda
I’m relatively new to birding as a hobby, and Birda is a great way to keep track off all the species I see. I’m still working on my ID skills, but the app is great for figuring out potential species, and the online community is so friendly and helpful. Definitely recommend Birda to both early and serious birders! 🐦
Such a great app!
I didn’t think I could enjoy birding more but this app makes it so much better. Some great features and a really great way to share your sightings with your friends or fellow birders nearby or around the world! ❤️
