About Lipaugus vociferans (Wied-Neuwied, 1820)
The screaming piha (scientific name Lipaugus vociferans (Wied-Neuwied, 1820)) is 24 to 26 cm (9.4 to 10 in) long and weighs 68 to 87 g (2.4 to 3.1 oz). Males and females have identical plumage. Adult individuals have medium gray upperparts; their tail, the flight feathers of their wings, and their greater coverts are browner or duskier in tone. Their underparts are a paler gray, and this gray is palest on the throat. The iris can be brown, grayish brown, or gray; the maxilla is black, and the mandible is dusky with a pinkish dusky base. The color of the legs and feet is highly variable, and includes dark shades of green, brown, gray, and black. Juvenile screaming pihas resemble adults, but have cinnamon rufous wing coverts and tail feather tips. The screaming piha has a disjunct distribution split into two separate ranges. The much larger of the two ranges covers most of the Amazon Basin and extends to the Atlantic Ocean through the Guianas. In addition to the Guianas, this range includes approximately the southeastern third of Venezuela, a similarly sized portion of Colombia, eastern Ecuador, eastern Peru, and northern Bolivia. From this area, the range extends across Brazil to a line running roughly between southern Mato Grosso and the Atlantic coast in Maranhão. The much smaller separate range is located in eastern Brazil, extending from Pernambuco south to Espírito Santo. The species inhabits lowland evergreen forest, and is found primarily in terra firme forest, but also occurs locally in igapó and várzea flooded forests. Its maximum elevation range differs across its distribution: it occurs from sea level up to 500 m (1,600 ft) in Brazil, up to 1,400 m (4,600 ft) in Venezuela (though most records in Venezuela are from below 900 m (3,000 ft)), up to 600 m (2,000 ft) in Colombia, up to 500 m (1,600 ft) in Ecuador, and up to 1,150 m (3,800 ft) in Peru.
