Source-derived summary

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.

Taxonomy

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).

Editorial summary

The public source identifies “Blue-crowned trogon” as species of bird. This brief keeps that definition visible, then builds a research path around Blue-crowned, trogon and species.

Editorial reviewA sound reference starting point where classification, measurement and the date of the underlying evidence remain visible. The current lead gives the account dated anchors—1766, 1648, 2008—that can be checked directly. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Blue-crowned, trogon and species providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Blue-crowned trogon”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.

Evidence profile

Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 28, 2025. The linked authority identifier is Q688318. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1766, 1648 and 2008.

Critical limits

A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
