Epimachus albertisi

Identification

Male 35cm, female 33cm. A fairly large Bird-of-paradise with a very long, sickle-shaped bill and a medium-length tail

  • Maroon-grey bare skin around eye
  • Dark brown iris
  • Buff tail

Distribution

Endemic to the mountains of New Guinea. Presumably a resident species.
Nowhere abundant but partly common. Has a small and patchily distribution.

Taxonomy

Subspecies

Two subspecies usually recognized[1]:

  • D. a. albertisi:
  • New Guinea (mountains of Vogelkop and Huon Peninsula)
  • D. a. cervinicauda:

Birds from the Huon Peninsula are sometimes described as subspecies geisleri. The proposed race inversus is usually synonymized with cervicauda.
May from a superspecies with Pale-billed Sicklebill and both are sometimes placed in the genus Epimachus.

Habitat

Middle montane forest and forest edges. Occurs at 600 - 2250m, mainly at 1100 - 1900m.

Behaviour

Diet

Feeds mainly on insects but takes also fruits.

Breeding

Breeding season at least from September to December. A polygynous species. The male advertises from one or more traditional high perches and performs its display. The territory around the perch is occupied by the male all year. The female builds and attends the nest alone.
The only known nest was a thin, rather flat structure. Lays 1 or 2 eggs.
