The Guianan trogon (Trogon violaceus) is a species of bird in the trogon and quetzal family Trogonidae. It is found in Brazil, French Guiana, Guyana, Suriname, Trinidad, and Venezuela. The Guianan trogon was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the other trogons in the genus Trogon and coined the binomial name Trogon violaceus. Gmelin based his account on a description and illustration by the German botanist Joseph Gottlieb Kölreuter that had been published 1765. Gmelin did not specify a type locality, but this has been designated as Suriname. The specific epithet violaceus is from Latin and means "violet-coloured". The species is now considered to be monotypic: no subspecies are recognised.
The Guianan trogon was formerly named the violaceous trogon and included the gartered trogon (T. caligatus) and the Amazonian trogon (T. ramonianus) as subspecies. A molecular phylogenetic study of the genus Trogon based on a single mitochondrial gene was published in 2008. It found that the Guianan trogon, the blue-crowned trogon (T. curucui... Wikipedia →

With luck
About 10% of wildlife watchers report a Guianan Trogon sighting in Brownsberg Nature Park on a given day, based on 35 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 221 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Guianan Trogon in Brownsberg Nature Park on a given day, against about 10% in March, August–September and November–January, the lowest months. That is one of Brownsberg Nature Park's wettest months, with about 300 mm of rain against 55 mm in October. May to July have too few records to rate.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Guianan Trogon sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brownsberg Nature Park, in our data
Brownsberg Nature Park is the only park on Wallace's Line with enough records to rate Guianan Trogon sightings: about 10% of wildlife watchers there report one on a given day.
Same genus: Trogon
The closest relatives of the Guianan Trogon that you can see in Brownsberg Nature Park (genus Trogon, New World Trogons) are Green-backed Trogon (about 30%), Black-throated Trogon (about 20%) and Collared Trogon (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Guianan Trogon is recorded against all the birds logged in Brownsberg Nature Park (35 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.
