Field notes

  • It is strictly endemic to the islands of Biak and Supiori in the Cenderawasih Bay of Papua, Indonesia.
  • The species occurs in two distinct color morphs: a common dark brown streaked phase and a rarer rufous phase.
  • Unlike many scops-owls with bright yellow eyes, this species typically possesses amber or dark yellowish-brown irises.
  • Taxonomically, it was formerly treated as a subspecies of the Moluccan Scops-Owl (Otus magicus) before being elevated to full species status.
  • It is currently classified as Vulnerable by the IUCN due to its very small range and ongoing habitat loss from logging and land conversion.
