In the first days of spring, birds undergo a spectacular metamorphosis. After a long winter of migration and peaceful co-existence, they suddenly begin to sing with all their might, varying each series of notes as if it were an audiophonic novel. They can’t bear the presence of other birds and begin to threaten and attack them if they cross a border, which might be invisible to human eyes but seems perfectly tangible to birds. Naturalists and ornithologists have put forward competing theories to try to explain this remarkable transformation.
