Alternative names: Moluccan Masked Owl; Tanimbar Owl
- Tyto sororcula
Includes: Seram Masked Owl, Buru Masked Owl
Identification
29-31cm. A small Masked Owl.
- Brownish upperparts mottled white
- Whitish underparts with dark spotting on sides
- Pale legs covered only with flesh-coloured bristles
- cayelii slightly larger, more tawny buff over all, more blackish upperparts
- almae with yellow-ochre underparts, more dusky on middle and lower back
Females larger as males. Juveniles undescribed.
Distribution
Found on Tanimbar, Buru and Seram (Indonesia).
A poorly known restricted-range species.
Taxonomy
Three subspecies recognized:
- T. s. sororcula on Tanimbar Island
- T. s. cayelii: "Buru Masked Owl". Buru Island (Southern Moluccas)
- T. s. almae: "Seram Masked Owl". Seram Island (Southern Moluccas)
almae is recognized as full species by Clements ("Seram Masked Owl"), however the other world lists don't yet follow this treatment and the Opus awaits further clarification. Subspecies cayelii may likewise be elevated as "Buru Masked Owl". Reference [3] suggests the differences between the forms are minor.
Habitat
Primary and mature secondary forest.
Behaviour
No information about diet or breeding.
Presumably a resident species.
