The grey whistler or brown whistler, is a species of bird in the family Pachycephalidae. It is found in northern Australia and New Guinea. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical mangrove forest.
Region
Northern Australia and New Guinea
Typical Environment
Occurs in tropical lowland rainforests, monsoon forests, vine thickets, and extensive mangrove systems across northern Australia and southern to northern New Guinea. It frequents forest edges, riverine corridors, and dense understory where it forages methodically. In mangroves it uses mid-story branches and pneumatophore zones during low tide. It tolerates lightly disturbed forest but is most numerous in intact, humid lowland habitats.
Altitude Range
Sea level to 800 m
Climate Zone
Tropical

Also called the brown whistler, this species has several subspecies that range from greyer to browner tones depending on locality. It favors quiet, shaded forest and mangrove habitats and is more often heard than seen. Its clear, piping whistles are a key cue for identification in dense foliage.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats, agile through understory
Social Behavior
Usually seen alone or in pairs, maintaining small territories within suitable forest. Pairs build neat cup nests in forks or suspended from slender branches in the mid-story. Breeding behavior includes frequent duet-like exchanges of whistles and short bouts of display.
Migratory Pattern
Resident
Song Description
Clear, mellow whistles delivered in short, repeated phrases, often from concealed perches. Phrases are pure-toned and carry well through dense vegetation, aiding territory advertisement and pair contact.
Plumage
Plain grey-brown upperparts with paler, buff-washed underparts; smooth, unpatterned look with slight olive tones in some subspecies. Throat usually paler, with a clean, neat appearance and fine feathering.
Diet
Primarily hunts insects and other small arthropods by gleaning from leaves, twigs, and bark. It occasionally sallies a short distance to capture flushed prey. Foraging is deliberate and methodical, focusing on shaded mid-story foliage and tangle zones.
Preferred Environment
Feeds within dense understory to mid-canopy of rainforest and mangroves, as well as along forest edges and riparian strips. Often works through vine thickets and leaf clusters where insects accumulate.
