Professor Elodie Briefer of the University of Copenhagen is an expert on communication with animals, and how their vocal signals contain information about what species they are, which group they're from, even their age, body size and dominance status.
How animals and birds sound, she's discovered, also reflects emotions and mood. She runs a Behavioural Ecology group at her university, with the goal of improving animal welfare.
