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 Amacayacu National Natural Park on a given day, based on 25 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 289th most-seen of the 436 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Grey-winged Trumpeter in Amacayacu National Natural Park on a given day, against under 5% in February to 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.
3rd of 4
Of the 4 parks where we can rate Grey-winged Trumpeter sightings, Amacayacu National Natural Park ranks 3rd at under 5%. The best odds are in Brownsberg Nature Park (Suriname, about 50%) and Yasuní National Park (Ecuador, under 5%).

GBIF citizen-science records
It is estimated from how often the Grey-winged Trumpeter is recorded against all the birds logged in Amacayacu National Natural Park (25 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.
