Hylocitrea bonensis
The Hylocitrea, *Hylocitrea bonensis*, also known as the Olive-flanked Whistler, is a captivating medium-sized passerine endemic to the montane forests of Sulawesi, Indonesia. Measuring approximately 14-15 cm in length and weighing 12-16 grams, its plumage is subtly beautiful, featuring olive-green upperparts, a greyish-brown crown and nape, and pale yellowish-white underparts that become distinctively olive-green on the flanks.

Found exclusively in montane evergreen and mossy forests of Sulawesi, often near forest edges or clearings, at elevations typically ranging from 1,000 to 2,200 meters.
Primarily insectivorous, feeding on insects and their larvae gleaned from foliage and branches, occasionally supplementing its diet with small berries or fruits.
The Hylocitrea is a diurnal species, moving deliberately and actively through the mid-story and sub-canopy of its forest home, frequently joining mixed-species foraging flocks alongside other insectivorous birds. It employs a gleaning foraging strategy, picking insects and their larvae from folia...
The Hylocitrea is strictly endemic to the island of Sulawesi, Indonesia, where it is distributed across various isolated mountain ranges. It can be found in the northern Minahasa Peninsula, through the central mountainous regions (notably Lore Lindu National Park), and extends into the southeaste...
