Range & population Treron oxyurus is restricted to Sumatra (350-1,800 m) and West Java (600-3,000 m), Indonesia; though formerly considered locally common it is now apparently very hard to find on both islands.

Ecology: It occurs in hill and montane forest, to 1,800 m in Sumatra and to 3,000 m in Java.

Threats Destruction of its preferred habitat has been widespread in the lower parts of its elevation range, and it is now rather scarce.

Conservation measures underway None is known.

Conservation measures proposed Survey to assess population size. Regularly monitor at certain sites throughout its range to determine population trends. Investigate the extent of hunting by local residents. If relevant, control hunting where possible, perhaps using awareness campaigns. Protect significant areas of primary montane forest across its altitudinal range.
