Olive-winged bulbul Pycnonotus plumosus

Large plain bulbul of lowland forests, edges, and mangroves. Dull brown with gray-streaked ear coverts, red eyes, and olive-green panels on the wings. Other similar large brown bulbuls such as Red-eyed and Cream-vented can also have olive tones in the wings, but less prominently. Song is a simple series of bubbly warbling interspersed with sharper notes.
