What is now the Ecuadorian trogon went through several scientific name changes. The last before the current binomial was Trogon melanurus mesurus, a subspecies of black-tailed trogon. Genetic studies in the early 2000s determined, that it is a species in its own right. It is monotypic.
The Ecuadorian trogon is 30.5 to 32 cm (12 to 13 in) long. One male weighed 96 g (3.4 oz) and a female 100 g (3.5 oz). The male has a black face and throat with a red ring around the eye. The crown, nape, upperparts, and upper breast are iridescent green. A white band separates the upper breast from the deep red lower breast, belly, and vent. The upperside of the tail is green, and the underside is slaty gray. The folded wing has fine black and grayish white vermiculation. The female replaces the male's green parts with shades of gray.

With luck
About 10% of wildlife watchers report an Ecuadorian Trogon sighting in Machalilla National Park on a given day, based on 58 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 108th most-seen of the 248 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
October and December
In those months about 20% of wildlife watchers report an Ecuadorian Trogon in Machalilla National Park on a given day, against under 5% in January–February, April–May, July–August and November, the lowest months. Those are among Machalilla National Park's driest months, with about 20 mm of rain a month against 140 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Ecuadorian 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 Machalilla National Park, in our data
Machalilla National Park is the only park on Wallace's Line with enough records to rate Ecuadorian Trogon sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Ecuadorian Trogon is recorded against all the birds logged in Machalilla National Park (58 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.
