The masked water tyrant is a striking, mostly white flycatcher that patrols the edges of water, often wagging its tail as it forages. It readily uses human-altered habitats such as parks, rice fields, and urban waterfronts. In Brazil it is popularly known as the “lavadeira-mascarada” (masked washerwoman) for its crisp white plumage and brisk movements.
