I think this is a green frog (Rana clamitans). I was pretty excited when it stood still and let me snap quite a few pictures. How cool, how friendly, I though.
But then it hit me: maybe it wasn't being friendly at all. Maybe it was frozen, frightened-- petrified! After all, this silver box was being shoved at it by some huge, gigantic mammal type being. Uh, yeah. That made more sense.
So I slunk away and left it to its froggy business.
