The Sumatran leafbird is a species of bird in the family Chloropseidae. It is endemic to forest and plantations in Sumatra in Indonesia. It has often been included as a subspecies of the golden-fronted leafbird, but the two differ extensively in, among others, morphology, with the male of the Sumatran leafbird having a yellow forehead, and the female resembling a female blue-winged leafbird, but with a yellowish forecrown and no blue to the wings and tail.
Region
Sundaic region (Sumatra)
Typical Environment
Occurs in humid evergreen lowland and hill forests across Sumatra, including forest edges, secondary growth, and mixed agroforests and plantations. It frequents the mid-story to canopy, often following flowering and fruiting trees. The species tolerates moderate disturbance and may visit orchards and village gardens near forest. However, it depends on a mosaic that retains tall trees and continuous canopy for foraging and nesting.

The Sumatran leafbird is endemic to Sumatra and was formerly treated as a subspecies of the golden-fronted leafbird. Males have a distinct yellow forehead and black face, while females resemble blue-winged leafbirds but lack blue in the wings and tail. Leafbirds are notable mimics, weaving phrases from other forest birds into their own songs. Trapping for the songbird trade and habitat loss are key threats to this species.
Temperament
active and territorial
Flight Pattern
short rapid wingbeats between trees; agile canopy flier
Social Behavior
Usually seen singly or in pairs, sometimes joining small mixed-species flocks in the canopy. During breeding, pairs defend small territories centered on favored fruiting or flowering trees. The female builds a suspended cup nest and incubates; the male often feeds the female and fledglings.
Migratory Pattern
Resident
Song Description
Rich, fluty whistles interspersed with chatters and trills. Skilled mimic that incorporates calls of other forest birds into a variable, melodious repertoire.
