French: Effraie de Manus German: Manuseule Spanish: Lechuza de la Manus
Other common names: Manus Owl, Admiralty Islands Masked-owl

Tyto manusi

Rothschild and Hartert

, 1914,

Manus, Admiralty Islands


Forms superspecies with T. novaehollandiae, T. aurantia, T. sororcula, T. nigrobrunnea and T. inexspectata. Sometimes considered conspecific with T. novaehollandiae. Evidence (subfossil bones)#R of extinct populations from Mussau and New Ireland may refer to undescribed races of present or closely related species, perhaps also isolated on single islands, and suggests that masked-owls may once have occurred more widely in Bismarck Archipelago. Monotypic.


Manus I, in Admiralty Is.
