Where have all my frogs gone?

[Cliygh and Mia 2]

I do know generalist species of raptor wouldn't mind going after adult frogs or tadpoles, so that could be an option. If a large storm system moved through, some of the adult frogs could have moved off to larger bodies of water. It's also likely they could still be in there, but hiding. Maybe it'd be worth placing a "Trail camera" around the area to see if the frogs are still there, or if a predator comes in the night.
