 A more intimate conversation call has also been noted in captive birds, only discernible within a metre, that repeats a sound transcribed as "qwirk" or "qwark"; Immelmann pronounced that this call seemed identical to the communication call of finches.The aviculturalist Pepper also described an alarm call, given in response to perceived threats to its young, that resembled one of "a broody [domestic] hen being removed from her nest".His observations of young in an aviary gives a report of their feeding call—a grating sound that slightly increases in pitch after fledging; the young signal to the parent with a repeated plea of "chik" and produce the feeding call when attended.
