|White-headed Marsh-tyrant Arundinicola
Brazilian name: freirinha
A Tyrant Flycatcher, the male White-headed Marsh-tyrant is quite distinct in appearance. It is slightly crested, black with the entire head and upper chest white and with a yellow lower mandible.
It has a chunky appearance and perches upright on vegetation above marshes and wetland such as the Pantanal. Compared to Fluvicola water-tyrants, it is rarely seen on the
ground and hardly ever spreads or cocks its tail.
|The female White-headed Marsh-tyrant has similar habits but looks very different and might be mistaken for a Black-backed Water-tyrant Fluvicola albiventer or a Pied Water-tyrant Fluvicola pica but it is more brownish above and less crispy white below.
