The blue-crowned trogon (Trogon curucui) is a species of bird in the family Trogonidae, the quetzals and trogons. It is found in Brazil, Argentina, Bolivia, Colombia, Ecuador, Paraguay, and Peru. As with all trogons, this species is sexually dimorphic. The male has a blue head with an orange orbital ring, a red belly with a narrow white breastband and a green back. The female differs in having a grey head, a grey back and a broken white eye-ring.
The blue-crowned trogon was formally described by the Swedish naturalist Carl Linnaeus in 1766 in the twelfth edition of his Systema Naturae. He placed it with the other trogons in the genus Trogon and coined the binomial name Trogon curucui. Linnaeus based his description on the "Curucui" that had been described and illustrated in 1648 by the German naturalist Georg Marcgrave in his book Historia Naturalis Brasiliae. The name "Curucui" and the specific epithet are derived from Surucui, a word from the extinct Brazilian Tupi language for a small bird. A 2008 molecular phylogenetic study of the genus Trogon found that the blue-crowned trogon was sister to the yellow-bellied Guianan trogon (T. violaceus).

With luck
About 10% of wildlife watchers report a Blue-crowned Trogon sighting in Fortaleza on a given day, based on 46 verified sightings from GBIF citizen-science data. It is the 65th most-seen of the 129 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
May
In that month about 30% of wildlife watchers report a Blue-crowned Trogon in Fortaleza on a given day, against under 5% in February and April, the lowest months. That is one of Fortaleza's wettest months, with about 150 mm of rain against almost none in September.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Blue-crowned 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.
2nd of 4
Of the 4 cities where we can rate Blue-crowned Trogon sightings, Fortaleza ranks 2nd at about 10%. The best odds are in Campo Grande (Brazil, about 20%).
GBIF citizen-science records
It is estimated from how often the Blue-crowned Trogon is recorded against all the birds logged in Fortaleza (46 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.
