Classification update: White-tailed Trogon

The White-tailed Trogon (formerly Trogon viridis) has been split into two species by the South American Classification Committee (SACC) on the basis of genetic and vocal differences. Birds west of the Andes (including western Peru, western Ecuador, western and northern Colombia and Panama) are now classified as Trogon chionurus (but will retain the name White-tailed Trogon). All other birds in South America, including Trinidad and Tobago, are now classified as Green-backed Trogon (Trogon viridis).
