One of the largest and most spectacular hummingbirds, the crimson topaz shimmers with jewel-like iridescence that inspired its name. Males have extremely long, racket-tipped tail feathers used in display flights over rivers. The species shows strong sexual dimorphism, with females much shorter-tailed and mainly green above. It is typically seen along forested rivers in the Guianas and northern Amazon Basin.
