Psophia is a genus of birds restricted to the humid forests of the Amazon and Guiana Shield in South America. It is the only genus in the family Psophiidae. Birds in the genus are commonly known as trumpeters, due to the trumpeting or cackling threat call of the males. The three species resemble slightly taller, longer-legged chickens in size and appearance; they measure 45 to long and weigh 1 to. and a “hunched” appearance. Their heads are small, but their eyes are relatively large, making them look inquisitive and "good-natured". The plumage is soft, resembling fur or velvet on the head and neck. It is mostly black, with purple, green, or bronze iridescence, particularly on the wing coverts and the lower neck. In the best-known taxa, the secondary and tertial flight feathers are white, grey, or greenish-black and hairlike, falling over the lower back, which is the same colour. These colours give the three generally accepted species their names.

Taxonomy and systematics

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:

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

Trumpeters fly weakly but run fast; they can easily outrun dogs. They are also capable of swimming across rivers. They spend most of the day in noisy flocks, sometimes numbering more than 100, on the forest floor. They feed on fallen fruit (particularly fruit knocked down by monkeys). They also eat a small amount of arthropods, including ants and flies, and even some reptiles and amphibians. At night they fly with difficulty into trees to roost 6 to above the ground.

Trumpeters nest in a hole in a tree or in the crown of a palm tree. They lay 2 to 5 eggs with rough, white shells, averaging about 76 g.

Relationship with humans

Trumpeters are often used as "guard dogs" because they call loudly when alarmed, However, another source says this prowess is "reputed".
