We don't get those sort of frogs here, but some years ago, a single male green frog found our goldfish pond. He called and called until he attracted six other males and a bevy of females, and they filled the pond with tadpoles. The adults shot through, and the tadpoles grew to the stage when they started to grow legs. We felt quite paternal, or in one case maternal.


Then the goldfish realised that tadpoles were edible. One day, all gone.
We learned:
Frogs scream when the cat catches them, loudly enough to startle the cat into letting go (once) and loudly enough to wake people up.
Frogs can only do about six jumps without taking a rest.
The local frog sounds like a two-stroke motor.
Middle-sized goldfish can wipe out a whole generation of frogs.

No wonder they are getting scsrce.
