Trogons (Trogonidae)

Violaceous Trogon (Trogon violaceus) - HBW 6, p. 114

French: Trogon violacé German: Veilchentrogon Spanish: Trogón Violáceo
Other common names: Gartered Trogon (caligatus), Amazonian Trogon (ramonianus)

Taxonomy: Trogon violaceus J. F. Gmelin, 1788, no locality = Surinam.
Sometimes placed in separate genus Chrysotrogon. DNA studies suggest possibly closest to T. viridis and T curucui. Races caligatus and ramonianus have both been treated as separate species by some authors. Northernmost race commonly labelled as braccatus, but name sallaei has priority. Extensive individual variation in degree of bronzy tinge on back in nominate and race caligatus led to description of rossi, now considered a synonym of nominate. Six subspecies recognized.

Subspecies and Distribution:

  • sallaei Bonaparte, 1856 - Caribbean slope of E & S Mexico, also Pacific slope of S Mexico, and Guatemala, Belize, El Salvador and N Honduras; possibly this race in Nicaragua.
  • concinnus Lawrence, 1862 - Costa Rica, Panama (except Caribbean slope of Darién), W Colombia, W Ecuador and NW Peru.
  • caligatus Gould, 1838 - NE Panama (Caribbean slope of Darién) into N Colombia and W Venezuela.
