Standard monetary unit of Guatemala (7)
I believe the answer is:
quetzal
(Other definitions for quetzal that I've seen before include "Vivid long-tailed bird of the Americas" , "Bird sacred to Mayas; Guatemalan currency" , "Resplendent bird of Central and South America - Guatemalan currency unit" , "Bright bird" , "Tropical bird with iridescent green plumage" .)
