The Western White-tailed Trogon is also known as the White-tailed Trogon. It is a near passerine bird in the Trogon family. It is found in tropical humid forests of the Chocó, ranging from Panama, through western Colombia, to western Ecuador.
This relatively large Trogon is 30 cm long. In the male the head and upper breast are dark blue, and the back is green, becoming bluer on the rump. The lower underparts are orange-yellow. The wings are black, vermiculited with white. The under-tail is almost entirely white with only a very narrow black base to each feather. The complete eye-ring is pale bluish. The female White-tailed Trogon resembles the male, but has a gray back, head and breast, and rather indistinct black-and-white barring to the inner webs of each tail feather.
