Abstract
We investigated park with pond in the city. Many water birds come at this park and visitors enjoy watching water birds. But the water quality damage has happened by extreme feeding action. A feeding pond was built to keep the water quality. We carried out questionnaire investigation. Many visitors agreed the prohibition of feeding. But, a little visitor knew the purpose of establishing of the feeding pond. And, 10% of answerer's consciousness for the prohibition of feeding changed from nays to ayes by the provision of information.
