The screaming piha (Lipaugus vociferans) is a species of bird in the Cotingidae family. It is found in humid forests in the Amazon and tropical parts of the Mata Atlântica in South America. As it is widespread and generally fairly common, it is considered to be of least concern by BirdLife International.
While the plumage of both sexes is dull grey (wings and tail often somewhat browner), its voice is extraordinary, exceptionally loud and among the most commonly heard sounds in the Amazon. The sound is frequently used in movies, and also can be heard in the background of the popular game Angry Birds Rio.
The Cofan people of Ecuador call it the Pwe-pwe Yoh, which is a reference to its voice. Similarly, among the Ecuadorian Secoyas, the bird is known as the Kwow-kwee-yo. Males often gather in loose leks, where they sing to attract females.
