Unique voice prints in parrots could help birds be recognized in a flock, no matter what they say
The nation has reeled from disaster to disaster in recent years, as it feels the effects of climate change.
Parrots are exceptional talkers. They can learn new sounds during their entire lives, amassing an almost unlimited vocal repertoire. At the same time, parrots produce calls so they can be individually recognized by members of their flock—raising the question of how their calls can be very variable while also uniquely identifiable.
