Vocalisation of the rare and flagship species Pharomachrus mocinno (Aves: Trogonidae): implications for its taxonomy, evolution and conservation [PDF]
Bioacoustics, 2019 The Resplendent Quetzal Pharomachrus mocinno is a rare Neotropical bird included in the IUCN red list as Near Threatened. Fragmentation of its habitat, the cloud forest, is considered as the principal threat. Two subspecies are currently recognised but genetic and morphometric studies suggested they could be considered as full species.
