The Pied Water Tyrant is a small passerine bird belonging to the tyrant flycatcher family. It is native to tropical South America, with its range extending from Panama and Trinidad south to Bolivia. The bird measures approximately 5.3 inches in length and weighing around 0.46 ounces. Adults display a striking color pattern, primarily white with black on the nape, back, wings, and tail. Both sexes have similar plumage, though females may exhibit some brown mixed with the black. Immature birds are brown where adults are black. Habitat-wise, the Pied Water Tyrant is typically found in marshy savannas and at the edges of mangrove swamps. The bird's nest is a unique feather-lined oval ball of grasses and other plant materials, featuring a side entrance and typically placed at the end of a branch near or over water. In a typical clutch, two or three creamy-white eggs are incubated by both sexes, and these eggs are marked with a few brown spots. An interesting behavior of the Pied Water Tyrant is its tendency to bob up and down when perched, and it also exhibits a fluttering "butterfly" display flight. The species primarily forages for insects in low waterside vegetation. In terms of conservation status, the Pied Water Tyrant is classified as Least Concern. It has a population size above 500,000 individuals.
