While rescuing injured birds, the swan wrapped his neck around the rescuer's neck.
Usually swans are very territorial and don't like human company, but Richard Wiese experiences a moving and wonderful moment during a rescue operation executed with several of his friends from a foundation aiding and rescuing injured birds in England. This is how he describes this moment:
"I lifted him, gently pressed on his chest so that he felt confident and safe. After a few moments the swan stopped resisting and literally wrapped himself around my neck. I could feel his heart beating besides mine. I wanted to shut my eyes in order to enjoy this moment completely. It's really a wonderful feeling when you sense a true connection and mutual trust- when an animal realizes you mean him no harm".
