Timor boobook
The Timor boobook (Ninox fusca) is a species of owl native to the eastern Lesser Sunda Islands, including Timor, Roma, Leti, and Semau. It is distinguished by its grey-brown plumage with grey streaks on its belly and white spots on its wings and nape, differing from the red tinge found in some related subspecies. Genetic and call analyses have led to its reclassification as a distinct species from the Australian boobook.

About Timor boobook
The Timor boobook, scientifically known as Ninox fusca, is a species of owl found in the eastern Lesser Sunda Islands. Its native range includes Timor, Roma, Leti, and Semau islands. This owl is notable for its distinct physical characteristics, setting it apart from closely related species.
Physical Characteristics and Classification
The Timor boobook displays grey-brown plumage, which is a key distinguishing feature as it lacks the red tinge present in some other subspecies. Additional identifying marks include grey streaks on its belly and white spots located on its secondaries, inner wing-coverts, and nape. Originally described by Louis Pierre Vieillot in 1817 as Strix fusca, it was later considered a subspecies of the Australian boobook by Carl Eduard Hellmayr and Ernst Mayr due to its resemblance.
Species Distinction
Recent genetic and call analyses have revealed significant divergence between the Timor boobook and Australian boobook populations. These findings led Gwee and colleagues to propose, and subsequently establish in 2019, its reclassification as a separate species. Its vocalizations are also noted to be shorter and more frequent than those of the Australian boobook, further supporting its distinct species status.
