The white-tailed trogon (Trogon chionurus) is a
Description
This relatively large trogon is 28 to 30 centimetres (11 to 12 in) long.
For comparison, the similar but smaller gartered trogon (T. caligatus) has a yellow (male) or incomplete white eye-ring (female), and the male also has bared to the undertail.[5]
There is no overlap in the distribution of the white-tailed and green-backed trogons, but the two can be separated by the undertail pattern: Unlike the white-tailed trogon, the male green-backed trogon has a broad black base to each feather, and the female has relatively distinct black-and-white barring mainly to the outer webs of each feather.[4] The male white-tailed trogon also has a bluer rump than the green-backed trogon.[5]
The song of the white-tailed trogon consists of 15-20 very fast cow notes.[5]
Ecology
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. White-tailed trogons feed mainly on small fruit, supplemented by arthropods – slightly more so in the dry season when fruit is scarce.
