Planinski barbet Psilopogon monticola

Faded-looking barbet of Borneo’s north-central mountain ranges. Grass-green above and pale green below, with a pale blue head, an off-white throat, and a bright red streak on the back of the head. Relatively common in montane and submontane forest and edge (most common 600–1200) but can be difficult to see. Listen for its song, a series of hollow, echoing notes comparable to a water bottle being emptied. Can be found in and around fruiting trees, sometimes in mixed flocks.
