The white-tailed trogon (Trogon chionurus) is a species of bird in the trogon family. It is found in tropical humid forests of the Chocó, ranging from Panama, through western Colombia, to western Ecuador. It was formerly considered a subspecies of T. viridis, which is widespread in South America east of the Andes, but under the English name white-tailed trogon (a name now reserved for T. chionurus, leaving T. viridis as the green-backed trogon).
This relatively large trogon is 28 to 30 centimetres (11 to 12 in) long. As most trogons, it is strongly sexually dimorphic. In the male the head and upper breast are dark blue (appears blackish in poor light), and the back is green, becoming bluer on the rump. The lower underparts are orange-yellow. The wings are black, vermiculated with white. The undertail is almost entirely white with only a very narrow black base to each feather. The complete eye-ring is pale bluish. The female white-tailed trogon resembles the male, but has a grey back, head and breast, and rather indistinct black-and-white barring mainly to the inner webs of each tail feather (less on outer webs).
For comparison, the similar but smaller gartered trogon... Wikipedia →

GBIF citizen-science records
It is estimated from how often the White-tailed Trogon is recorded against all the birds logged in San Lorenzo Protected Forest (65 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.
