Blue-masked Leafbird Chloropsis venusta

Justification
This species is thought to have experienced a moderately rapid decline which is likely to continue owing to ongoing loss and degradation of forest within its restricted altitudinal range. As a result it is classified as Near Threatened.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
This species is restricted to the hills and lower montane areas of Sumatra, Indonesia, occurring throughout the uplands that run along the western spine of the island.

Population justification
The population size is unknown, but the species is described as generally rather uncommon to sparse (del Hoyo et al. 2006).

Trend justification
This species has probably declined owing to loss of forest at the lower margin of its altitudinal range, restricting it to higher elevations.

Ecology
It inhabits hill and lower montane evergreen forest at 600-1,500 m. It also occurs in well-regenerated secondary growth and at the forest-edge. It feeds on fruit, seeds and arthropods.

Threats
It is judged to be generally uncommon and sparse but forest loss on lower slopes is reducing the lower elevation ranges of several rare Sumatran endemics, and is likely to be causing a decline in this species also (BirdLife International 2001, Wells 2005.

Conservation Actions Underway
None are known. Conservation Actions Proposed
Assess the rate of forest loss within its altitudinal range using remote sensing techniques. Ensure that adequate areas of lower montane forest are protected within its range.
