Bulbul à tête blanche Hypsipetes thompsoni

Unmistakable gray bulbul with a striking white head, rose-red bill, and orange vent. Passingly similar to white-headed forms of unrelated Black Bulbul but lacks shaggy crest, dark vent, and inky-black body of that species. Gives harsh, chattering, somewhat parrot-like calls while flocking. Song is a repetitive and squeaky series of distinct two-note phrases. Breeds in foothills and montane areas, preferring open forests and forest edges. Descends into foothills and lowlands during non-breeding season.
