I count the frogs in the pond everyday while feeding the fish. They have many hiding places, and I pride myself finding them in their secret spots day after day- but I don't find them all. Today I had a record count of 9 frogs in the pond, many of them are small so we may have had a brood hatch this year, though I have not seen a tadpole. I imagine they hid very well to be safe from the fish.
