The blue-masked leafbird is a species of bird in the family Chloropseidae. It is endemic to humid montane forest in the western regions of the Indonesian island of Sumatra. Generally, it lives in areas from 600 to 1,500 m in elevation. It is the smallest species of leafbird.
Region
Western Sumatra montane forests
Typical Environment
Found in humid montane and submontane forests along the Barisan Mountains of western Sumatra. It favors mature mossy forest with a dense canopy and frequents forest edges, ridgelines, and areas with fruiting and flowering trees. The species also uses well-vegetated secondary growth and forest patches, provided canopy resources are available. It is typically observed in the mid to upper canopy and occasionally along forest edges near clearings.
Altitude Range
600–1500 m

The blue-masked leafbird is the smallest member of the leafbird family, with males showing a vivid cobalt-blue facial mask and throat. It is confined to humid montane forests of western Sumatra and often joins mixed-species flocks high in the canopy. Like other leafbirds, it can mimic snippets of other birds’ songs. Habitat loss and trapping for the cage-bird trade are potential threats within its limited range.
Temperament
shy and canopy-dwelling
Flight Pattern
short rapid wingbeats with agile, darting movements between canopy perches
Social Behavior
Often seen in pairs or small family groups and frequently joins mixed-species flocks when foraging. Territorial during breeding, with activity concentrated in fruiting or flowering trees. Builds a small cup-like nest placed on outer branches; both adults participate in care of young.
Migratory Pattern
Resident
Song Description
A mix of clear whistles and metallic notes delivered from high perches. Known to incorporate mimicry of other forest birds, with varied phrases and brief, repeated motifs.
Plumage
Bright leaf-green body with a contrasting blue mask and throat; fine, sleek plumage suited for canopy life. Wings and tail show darker green with subtle bluish edging. Females are duller overall and may show a more subdued bluish cheek area rather than a full mask.
Diet
Takes small fruits and berries, especially figs, and sips nectar from flowering trees. Also gleans insects and spiders from foliage and occasionally hawks flying insects. Foraging is methodical in the canopy, with short sallies between fruiting or flowering crowns.
Preferred Environment
Primarily forages in the mid to upper canopy of montane forest, especially at fruiting figs and blossoming trees. Uses forest edges and secondary growth when resources are abundant.
