3–8, see text Psophia is a genus of birds restricted to the humid forests of the Amazon and Guiana Shield in South America.

[1] The three species resemble slightly taller, longer-legged chickens in size and appearance; they measure 45 to 52 centimetres (18 to 20 inches) long and weigh 1 to 1.5 kg (2.2 to 3.3 lb).

[1] They are rotund birds with long, flexible necks and legs, downward-curving bills[2] and a “hunched” appearance.

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.

[1][13] Trumpeters are often used as "guard dogs" because they call loudly when alarmed,[1] become tame easily, and are believed to be adept at killing snakes.

One source states their skill at hunting snakes as a fact,[3] and the nineteenth-century botanist Richard Spruce gave an account of the friendliness and snake-killing prowess of a tame grey-winged trumpeter.
