The least boobook, also known as the little Sumba hawk-owl or little Sumba boobook, is a species of owl in the family Strigidae. It is endemic to the Indonesian island of Sumba. Its natural habitat is subtropical or tropical moist lowland forests. It is threatened by habitat loss.
Region
Lesser Sunda Islands
Typical Environment
Confined to Sumba’s subtropical and tropical moist lowland forests, including semi-evergreen forest and tall secondary growth. It occurs along forest edges, riparian strips, and lightly disturbed mosaics when large trees and cavities remain. Dense understory and midstory perches are important for sit-and-wait hunting. It generally avoids heavily cleared farmland and urban areas.
Altitude Range
Sea level to 600 m
Climate Zone
Tropical
Ease of Keeping

The least boobook, also called the little Sumba hawk-owl, is one of the smallest boobooks and occurs only on the Indonesian island of Sumba. It favors lowland forests and is primarily nocturnal, often detected by its high-pitched, repetitive hoots. Habitat loss from logging and agricultural expansion is the main threat to its survival. Protecting remaining lowland forest tracts on Sumba is crucial for this species.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats with agile, low forest flights between perches
Social Behavior
Usually encountered singly or in pairs, especially during the breeding season when pairs defend territories. Nests in natural tree cavities or old woodpecker holes, relying on mature trees. Activity peaks at dusk and night, with daytime roosting in dense foliage.
Migratory Pattern
Resident
Song Description
A high-pitched, repetitive series of clear hoots, often delivered in steady tempo. Males call persistently at dusk and during the night, with duets or call-and-response between pair members.
