I have at least six frogs in my pond this spring. They overwintered from last year’s tadpoles caught in a local lake. I love these frogs. They croak and splash about in the small pond bringing me great pleasure. I would have more frogs, but last year mallard ducks used my pond as a feeding trough, eating many goldfish and tadpoles. This year, the ducks returned, but I was ready and covered the pond with mesh to keep the hungry birds away.
