The white-rumped triller is a small cuckooshrike notable for its contrasting white rump, which flashes in flight. It forages methodically among foliage, often in pairs or small family groups, and frequents both primary and secondary lowland forests as well as mangroves. Its sharp, repetitive trills carry through the canopy, making it easier to detect than to see.

alert and active, somewhat shy near dense cover
Flight Pattern
short rapid wingbeats with brief glides between perches
Social Behavior
Usually seen singly, in pairs, or in small family groups; may associate loosely with mixed-species flocks in the canopy. Likely monogamous, maintaining small territories in suitable forest patches. Nests are shallow cups placed on horizontal forks high in trees.
Migratory Pattern
Resident
Song Description
A series of sharp, metallic trills and clear whistles delivered from exposed perches. Calls are repetitive and carry well, often used to maintain contact between pair members.
