Emits deep, resonant honking calls and loud wing-whirring display flights. Andean cloud forest echoes with both calls and wing-whirring at dawn across multiple Penelope guans.
Highland Guan
Produces a loud, resonant cackling call and wing-whirring display. The male's calls carry through Central American cloud forest; wing-whirring display is a key feature of this highland cracid.

About These Birds
Andean Guan
A medium-sized cracid (~650 g) of family Cracidae, with dull brown-olive plumage and a bare red throat wattle. Inhabits Andean cloud forests and forest edges from Venezuela south to Bolivia at elevations of 1,200–3,500 m. Feeds on fruits, seeds, and invertebrates. Least Concern; widespread in montane Andes and one of the more commonly encountered Penelope guans.
Highland Guan
A medium-sized cracid (~890 g) of family Cracidae, sexually dimorphic—males glossy black with red wattle, females brown. Inhabits cloud forests and humid montane forests in the highlands of Mexico, Guatemala, Honduras, El Salvador, and Nicaragua. Arboreal frugivore. Vulnerable due to deforestation and hunting in the fragmented highlands of Mesoamerica.
