Utterly unmistakable inhabitant of waterside and riverine lowland evergreen forests, mangroves, and plantations. Midnight black with long white slashes on each wing, wine-red underparts, and a black chinstrap. Bulbous bill is glowingly powder-blue with warm tinges of orange and greenish-yellow. During the breeding season, the pendulous nests of this species can be quite obvious, hanging over forested waterways. Voice is nasal and generally unpleasant-sounding, consisting of odd low mechanical rasps.
