The Wetar oriole is a species of bird in the family Oriolidae. It is endemic to the Lesser Sundas, where it is found on Wetar and Atauro Islands. Its natural habitats are subtropical or tropical dry forests and subtropical or tropical mangrove forests.
Region
Lesser Sunda Islands
Typical Environment
Occurs on Wetar (Indonesia) and Atauro (Timor-Leste), mainly in subtropical to tropical dry forest, open monsoon woodland, and mangrove edges. It uses forest edges, secondary growth, and riverine strips where large fruiting trees occur. The species forages mostly in the mid to upper canopy but will descend to lower levels at forest margins. It tolerates some habitat disturbance provided tall trees remain.
Altitude Range
Sea level to 1000 m

The Wetar oriole is a canopy-dwelling oriole restricted to Wetar (Indonesia) and nearby Atauro Island. It favors dry monsoon forests and mangroves, where it often stays high and is more often heard than seen. Some authorities have treated it as part of a Timor–Wetar oriole complex, but vocal and plumage differences support its recognition. Its mellow, fluty whistles carry well through open woodland.
Temperament
shy and canopy-oriented
Flight Pattern
direct flight with short, rapid wingbeats; occasional undulating passages between tree crowns
Social Behavior
Usually seen singly or in pairs, sometimes in small family parties. Often joins mixed-species flocks when foraging in the canopy. Builds a neat, suspended cup nest slung from a forked branch high in a tree. Both parents likely participate in rearing the young.
Migratory Pattern
Resident
Song Description
A series of mellow, fluty whistles and rich, liquid phrases, often delivered from concealed perches. Also gives harsher scolding notes when alarmed. Song carries well in open woodland during early morning.
Plumage
Overall olive-brown to dusky-olive with paler yellow-olive underparts and a slightly brighter rump and undertail. Lores and eye-line are dusky, giving a subtle masked look. Wings and tail are darker brown without bold wing bars; throat often a shade paler. Feathers appear smooth and sleek, typical of orioles.
Diet
Takes a mix of fruits—especially figs and other soft berries—and a variety of insects such as beetles, caterpillars, and orthopterans. Gleans prey from leaves and twigs and occasionally probes into bark crevices. Will sally short distances to snap flying insects and may sip nectar opportunistically. Diet shifts with seasonal fruiting and insect abundance.
Preferred Environment
Feeds mainly in the mid to upper canopy of dry forest, monsoon woodland, and mangrove fringes. Frequently visits fruiting trees along forest edges and in lightly disturbed secondary growth. Uses riverine corridors and tall isolated trees in open areas.
