Typical Environment
Occurs throughout moist montane forests on the island of New Guinea, including both primary and secondary growth. It frequents forest interiors, edges, and light gaps where it can maneuver through the understory and mid-story. The species also uses mossy forest and riparian corridors along mountain streams. It is locally common where suitable habitat persists and often follows mixed flocks along ridges and slopes.

True to its name, the dimorphic fantail occurs in two plumage morphs—dark and pale—which can appear together in the same area. It is an agile insect-hunter that constantly fans and flicks its tail while sallying for prey in the montane forests of New Guinea. Often joining mixed-species flocks, it helps flush insects from foliage with its restless movements.
Temperament
social and active
Flight Pattern
short rapid wingbeats
Social Behavior
Usually found singly or in pairs, it readily joins mixed-species flocks moving along montane slopes. Pairs are likely territorial during breeding, building a small, neat cup nest in a forked branch or sapling. Both adults may participate in nest defense with conspicuous tail-fanning and chattering displays.
Migratory Pattern
Resident
Song Description
A series of thin, high-pitched whistles interspersed with soft trills and chatters. Calls are often delivered while foraging and can accelerate into excited scolding when disturbed.
