The Biak Island Scops Owls (Otus beccarii) - also known as Beccari Scope Owls, Moluccan Scops Owls or Papuan Scops Owls - are endemic to the twin islands of Biak-Supiori in Geelvink Bay, off northwestern New Guinea Papua (formerly Irian Jaya) in Indonesia.

Their primary habitats are forests, including partially logged forests, up to at least 1,000 feet (300 m) and coastal swamp forests bounded by heavily forested limestone cliffs. They appear to avoid heavily logged or degraded forests

Biak Scops Owls have a very small range and are endangered due to destruction of their forest habitats, and their numbers are suspected to be declining.


The Biak Scops Owls measure about 8 - 10 inches (20 - 25 cm) in length.

They have short, inconspicuous ear-tufts and densely barred brown upperparts with some white on the scapulars (shoulder feathers). The plumage below is brown or rich rufous, with fine barring.

They have yellow eyes, pale whitish eyebrows and facial discs.

Similar Species:

The only other owls occurring within their range -- the Papuan Frogmouth Podargus papuensis and Large-tailed Nightjar Caprimulgus macrurus -- can easily be differentiated by their long tails.
