The Ecuadorian trogon (Trogon mesurus) is a species of bird in the family Trogonidae, the quetzals and trogons. It is found in Ecuador and Peru. 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.
The Ecuadorian trogon is found from Ecuador's most northerly province, Esmeraldas, south into Peru's Lambayeque Province. It inhabits the edges and... Wikipedia →

Rare
Under 5% of wildlife watchers report an Ecuadorian Trogon sighting in Guayaquil on a given day, based on 25 verified sightings from GBIF citizen-science data. It is the 98th most-seen of the 167 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.
September and November
In those months about 10% of wildlife watchers report an Ecuadorian Trogon in Guayaquil on a given day, against under 5% in October and December–August, the lowest months. Those are among Guayaquil's driest months, with about 5 mm of rain a month against 220 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 Guayaquil, in our data
Guayaquil is the only city on Wallace's Line with enough records to rate Ecuadorian Trogon sightings: under 5% 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 Guayaquil (25 verified sightings), 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.
