The White-tailed Trogon (Trogon chionurus) is found in tropical humid forests of the Chocó, ranging from Panama, through western Colombia, to western Ecuador.
It was formerly considered a subspecies of Trogon viridis, which is widespread in South America east of the Andes, but under the English name White-tailed Trogon (a name now reserved for Trogon chionurus, leaving Trogon viridis as the Green-backed Trogon).
