Demon Barbatos: Pseudomonarchia Daemonum
Barbatos is a great earl (count) and also a duke. He appears with four Kings, which bring companies and great troops with them.
Barbatos understands the singing of birds, the barking of dogs and the lowing of bullocks, and the voices of all living creatures. This spirit detects treasures hidden by magicians.
He knows all things past and to come, and reconciles friends and powers. He rules 30 legions of devils.

A video about Barbatos
I have summoned Barbatos for the purpose of learning the language of cockatoos, because I own such a pet. The ability to understand the noises and the body language of cockatoos was granted to me instantly.
This video is about Barbatos and how he can help people to communicate with animals by teaching people the animal language.
