Pharomachrus

Pharomachrus is a genus of birds in the family Trogonidae. "Pharomachrus" is from Ancient Greek "pharos", "mantle", and "makros", "long", referring to the wing and tail coverts of the resplendent quetzal (the second "h" is unexplained).
The five species of this genus and the eared quetzal, the only living member of the genus "Euptilotis", together make up a group of colourful birds called quetzals.
