Violaceous Trogon

The Violaceous Trogon (Trogon violaceus) is a near passerine bird in the trogon family, Trogonidae. It is found in humid forests in the Amazon Basin of South America and on the island of Trinidad, although some authorities have argued for treating the west Amazonian population as a separate species, the Amazonian Trogon (T. ramonianus). Until recently, the Gartered Trogon (T. caligatus) of Mexico, Central America and north-western South America was generally considered a subspecies of the Violaceous Trogon.


It is a resident of moist tropical forests, where it nests in a wasp, ant or termite nest or a hole in a rotten tree, with a typical clutch of two or three white eggs.

Violaceous Trogons feed on insects and small fruit, and their broad bills and weak legs reflect their diet and arboreal habits. Although their flight is fast, they are reluctant to fly any distance. They typically perch upright and motionless.


Trogons have distinctive male and female plumages, with soft, often colourful, feathers. This relatively small species is about long and weighs . The head and upper breast of the male are blue and the back is green, becoming bluer on the rump. A white line separates the breast from the orange yellow underparts. The undertail is white with black barring, and the wings are black, vermiculated with white. The complete eye-ring is yellow. The female Violaceous Trogon resembles the male, but has a dark grey back, head and breast, and an incomplete white eye-ring.

This species resembles the White-tailed Trogon, but the latter is larger and has a complete pale blue eye-ring in both sexes. Furthermore, the male White-tailed Trogon lacks barring to the undertail.

The shade of the blue of the head in the male differs between the Violaceous Trogon and the Gathered Trogon, but (disregarding their separate distributions) the call is the main distinction between the two. The Gathered has a slurred whistled cuh-cuh-cuh, and Violaceous has a soft cow cow, cow.


Database entry includes justification for why this species is of least concern

South American Classification Committee (2008). Recognize Trogon caligatus as a separate species from Trogon violaceus (2).
