I don't know if it would work or not but I would try to make something with straws (the sipping kind) or the small ones that come in coffee or alcohol drinks. Not sure how it could be attached to his head, tape would pull feathers. Maybe an old nylon and make a cap.
Would be a lot of experimenting with different types of materials to get it to stay put. Sorry really no help. Hope it heals whatever needs to be done.
