Gérygone des mangroves Gerygone levigaster

Small plain bird with thin bill. Upperparts gray, underparts whitish, with striking white tail spots (best seen in flight), pale eyebrow, and red eye. Usually detected by song, a tinkling melodious string of notes moving up and down in pitch (like a musician practicing scales). Inhabits mangroves and surrounding habitats, unlikely to be far from mangroves.
