The Rennell whistler is a species of bird in the family Pachycephalidae, which is endemic to the Rennell Island in the Solomon Islands. It was split from the Bismarck whistler by the IOC in 2016.
Region
Southwest Pacific (Solomon Islands)
Typical Environment
Occurs only on Rennell Island, where it inhabits lowland tropical rainforest, forest edges, and secondary growth. It uses the understory to mid-canopy, frequently moving through vine tangles and along leafy branches. The species is recorded around East Rennell (Lake Tegano) as well as in interior forest tracts. It tolerates lightly disturbed habitats but is most abundant in mature forest. Gardens with substantial tree cover may also be used for foraging.

The Rennell whistler is confined to Rennell Island in the Solomon Islands and was recognized as distinct from the Bismarck whistler by the IOC in 2016. Like other whistlers, it has a clear, ringing voice and is often detected by sound before sight. It typically forages in the midstory, making short sallies to pick insects from leaves and branches.
Temperament
solitary and territorial
Flight Pattern
short rapid wingbeats
Social Behavior
Usually seen singly or in pairs, maintaining territories within forested habitats. Pairs are monogamous during the breeding season and defend nesting areas with persistent song. The nest is a small cup placed in a fork or suspended from slender branches, and both parents participate in care.
Migratory Pattern
Resident
Song Description
A series of clear, fluted whistles delivered at measured pace, often repeated from a favored perch. Notes are rich and ringing, carrying well through the forest. Calls include sharp chips and softer contact notes between pair members.
Plumage
Compact whistler with smooth, close-lying plumage; males show bright, clean coloration while females are duller and more olive-brown with buff underparts. Plumage appears tidy with slight gloss on darker areas.
Diet
Takes a wide variety of arthropods, including beetles, caterpillars, spiders, and other small insects gleaned from foliage and bark. It occasionally hawks short distances to snatch flying prey. Small fruits and berries are also consumed, especially when insect prey is less abundant. Foraging is methodical, with frequent pauses to scan leaves and branches.
Preferred Environment
Forages in the understory to mid-canopy of primary and secondary rainforest, along edges, and in well-treed gardens. It often works along vine-laden branches and among dense leaf clusters where insects are plentiful.
