Sulphur-bellied Bulbul Iole palawanensis

A medium-sized bird of forest and edge in the mountains on Palawan. Olive-brown above, blending to a more brownish crown which can be slightly raised into a crest, with a yellow belly blending to an olive chest and a whitish throat. Note the pale orange eye. Somewhat similar to Ash-fronted Bulbul, but has yellow belly and pale eyes. Call is a simple nasal “chewp!”
