A seemingly successful swan rescue took a disturbing turn when the released cygnet was attacked by its own parents. After being treated by rescuers, the young swan was returned to the water, anticipating reunification with its family. However, the adult swans aggressively pursued the cygnet, attempting to submerge it. Rescuers were forced to intervene a second time, saving the bird from its own parents. The incident suggests a rejection of the cygnet, the reasons for which remain unclear. This unusual behavior highlights the complexities of animal behavior and the potential for unexpected outcomes even in seemingly positive rescue situations.
