The grey-winged trumpeter (Psophia crepitans) is a member of a small family of birds, the Psophiidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, northern Peru, Suriname, and Venezuela, north of the Amazon River.
The grey-winged trumpeter was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae under current the binomial name Psophia crepitans. Linnaeus based his account on the earlier description by the French naturalist Pierre Barrère. Linnaeus specified the type locality as "America meridionali" but this is now restricted to Cayenne in French Guiana based on Barrère. The specific epithet is Latin meaning "breaking wind" or "resounding".
The grey-winged trumpeter's taxonomy is unsettled. The International Ornithological Committee (IOC), the South American Classification Committee of the American Ornithological Society, and the Clements taxonomy recognise three subspecies: Wikipedia →

Rare
Under 5% of wildlife watchers report a Grey-winged Trumpeter sighting in Cuyabeno Wildlife Reserve on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 253rd most-seen of the 328 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
January and March
In those months about 10% of wildlife watchers report a Grey-winged Trumpeter in Cuyabeno Wildlife Reserve on a given day, against under 5% in February and April–December, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Grey-winged Trumpeter sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 4
Of the 4 parks where we can rate Grey-winged Trumpeter sightings, Cuyabeno Wildlife Reserve ranks 4th at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 50%), Yasuní National Park (Ecuador, under 5%) and Amacayacu National Natural Park (Colombia, under 5%).
GBIF citizen-science records
It is estimated from how often the Grey-winged Trumpeter is recorded against all the birds logged in Cuyabeno Wildlife Reserve (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
