The white-bellied whistler is a species of bird in the family Pachycephalidae. The species has an oddly discontinuous distribution, occurring in two small patches of northern New Guinea, one small patch in south eastern New Guinea and on Rossel Island in the Louisiade Archipelago. The species uses a variety of habitats, including wet eucalyptus forests, mangrove forests, savanna, and modified habitats like rubber plantations.
Region
New Guinea and Louisiade Archipelago
Typical Environment
The species occurs in disjunct pockets of northern and southeastern New Guinea and on Rossel Island. It inhabits wet eucalypt forests, mangrove forests, coastal thickets, savanna woodlands, and secondary growth including plantation edges. Birds often use forest margins, riverine belts, and dense understory where they can forage quietly. It adapts to modified habitats such as rubber and mixed-crop plantations provided sufficient shrub cover remains.
Altitude Range
Sea level to 900 m

This whistler has a notably patchy distribution across New Guinea, including Rossel Island, where it occupies mangroves, eucalypt forests, and savanna edges. It forages methodically through foliage and often joins mixed-species flocks. Its loud, melodious whistles carry far through dense vegetation, making it easier to detect by ear than by sight. Despite its fragmented range, it is not currently considered at risk.
Temperament
quiet and secretive
Flight Pattern
short rapid wingbeats between perches
Social Behavior
Usually found singly or in pairs, maintaining territories during the breeding season. Frequently accompanies mixed-species flocks while foraging. Nests are small, neat cups placed low to mid-level in dense vegetation.
Migratory Pattern
Resident
Song Description
A series of clear, ringing whistles delivered in short phrases, often repeated from a concealed perch. Calls include sharp chips and soft churrs used as contact and alarm notes.
