The Tanimbar boobook (Tanimbar hawk-owl) is an owl endemic to Indonesia’s Tanimbar Islands and was formerly treated as a subspecies of the Moluccan boobook. Its duet-like “boo-book” calls are a key field clue at night. It tolerates secondary growth and village edges but is affected by ongoing forest loss. As with many Ninox owls, it often hunts insects drawn to artificial lights.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats with agile, low forest-level flight
Social Behavior
Typically found alone or in pairs, especially during the breeding season. Pairs are likely monogamous and defend small territories. Nests are placed in natural tree cavities or holes in large limbs, with a small clutch of eggs.
Migratory Pattern
Resident
Song Description
Gives a repetitive, resonant two-note “boo-book” or “pook-pook” call, often in duets. Also produces gruff barks and screeches when alarmed or in territorial disputes.
