The
genus Psophia was introduced in 1758 by the Swedish naturalist
Carl Linnaeus, in the
tenth edition of his
Systema Naturae, as containing a single species, the
grey-winged trumpeter (
Psophia crepitans). The genus name is from the
Ancient Greek psophos meaning "noise". The genus' taxonomy is far from settled; anywhere from three to six species (with varying numbers of subspecies) are recognized by different taxonomic systems. The
International Ornithological Committee's treatment is the most conservative. They recognize three species, two of which have three subspecies: •
Grey-winged trumpeter,
Psophia crepitans •
P. c. crepitans •
P. c. napensis •
P. c. ochroptera •
Pale-winged trumpeter,
Psophia leucoptera •
Dark-winged trumpeter,
Psophia viridis •
P. v. viridis •
P. v. dextralis •
P. v. obscura The Clements taxonomy splits
P. v. dextralis and adds English names to the subspecies: • Gray-winged trumpeter,
Psophia crepitans •
P. c. crepitans (gray-winged) •
P. c. napensis (Napo) •
P. c. ochroptera (ochre-winged) • Pale-winged trumpeter,
Psophia leucoptera • Dark-winged trumpeter,
Psophia viridis •
P. v. viridis (green-backed) •
P. v. dextralis (dusky-backed) •
P. v. interjecta (Xingu) •
P. v. obscura (black-backed)
BirdLife International's
Handbook of the Birds of the World (HBW) recognizes six species: • Grey-winged trumpeter,
Psophia crepitans •
P. c. crepitans •
P. c. napensis • Ochre-winged trumpeter,
Psophia ochroptera • White-winged trumpeter,
Psophia leucoptera • Green-winged trumpeter,
Psophia viridis • Olive-winged trumpeter,
Psophia dextralis •
P. d. dextralis •
P. d. interjecta • Black-winged trumpeter,
Psophia obscura Traditionally, only three species of trumpeters have been recognised. A 2008 review, of the
morphology of the dark-winged trumpeter, resulted in the recommendation that it be divided into three species. A 2010 review of the
phylogeny and
biogeography of all members of the family resulted in a suggested total of eight species—two in the grey-winged trumpeter
complex, two in the pale-winged trumpeter complex, and four in the dark-winged trumpeter complex. ==Behaviour and ecology==
