Appearance
This relatively large trogon is 28 to 30 centimetres long. As most trogons, it is strongly sexually dimorphic. In the male the head and upper breast are dark blue, and the back is green. The lower underparts are orange yellow. The wings are black, vermiculated with white. The undertail is black and white: Each feather has a broad black base and a broad white tip and outer edge. The complete eye-ring is pale bluish.The female Green-backed Trogon resembles the male, but has a grey back, head and breast, and distinct black-and-white barring mainly to the outer webs of each tail feather.
For comparison, the similar but smaller Violaceous Trogon has a yellow or incomplete white eye-ring, and the male also has barring to the undertail.
Behavior
The song of the Green-backed Trogon consists of about 20 "cow" notes that start slow, but accelerate towards the end. The song is slower than the White-tailed Trogon, and higher pitched than the Black-tailed Trogon.They typically perch upright and motionless. Although their flight is fast, they are reluctant to fly any distance. Their broad bills and weak legs reflect their diet and arboreal habits.
Habitat
It is a resident of humid tropical forests, and it typically is the commonest trogon in its range.
Reproduction
It nests in a termite nest or a hole in a rotten tree. The nest is usually if not always built by the female which excavates an upward-sloping tunnel ending in a breeding chamber. The nesting season is apparently mainly during the summer months.The clutch is typically two or three white eggs. These are incubated for 16–17 days, with a further two weeks to fledging.
Food
Green-backed Trogons feed mainly on small fruit, supplemented by arthropods – slightly more so in the dry season when fruit are scarce, but even then they seems to be among the most frugivorous trogons in their range. They are consequently more rarely seen to attend mixed-species feeding flocks than other trogons.References:
