 Around five separate communication calls of the red-eared firetail had been reported by the late twentieth century, these have been classified in several ways from reports in the field or aviary.Adult vocalisation is distinguished as an identity call, intimate nest-calls, a nest-site call, and a contact or communication call (Pepper, Immelmann) only reported in captives.Additional records in aviculture are for huffing, distress, aggression and alarm calls.
