Description
Trogons have distinctive male and female plumages, with soft, often colourful, feathers. This relatively small species is about 23 centimetres (9.1 in) long and weighs 56 grams (2.0 oz). The head and upper breast of the male are blue and the back is green, becoming bluer on the rump. A faint 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 Gartered Trogon, but (disregarding their separate distributions) the call is the main distinction between the two. The Gartered has a slurred whistled cuh-cuh-cuh, and Violaceous has a soft cow cow, cow.

Famous quotes containing the word description:
“I was here first introduced to Joe.... He was a good-looking Indian, twenty-four years old, apparently of unmixed blood, short and stout, with a broad face and reddish complexion, and eyes, methinks, narrower and more turned up at the outer corners than ours, answering to the description of his race. Besides his underclothing, he wore a red flannel shirt, woolen pants, and a black Kossuth hat, the ordinary dress of the lumberman, and, to a considerable extent, of the Penobscot Indian.”
—Henry David Thoreau (1817–1862)
“The type of fig leaf which each culture employs to cover its social taboos offers a twofold description of its morality. It reveals that certain unacknowledged behavior exists and it suggests the form that such behavior takes.”
—Freda Adler (b. 1934)
“The great object in life is Sensation—to feel that we exist, even though in pain; it is this “craving void” which drives us to gaming, to battle, to travel, to intemperate but keenly felt pursuits of every description whose principal attraction is the agitation inseparable from their accomplishment.”
—George Gordon Noel Byron (1788–1824)
