We only have a half dozen or so frogs in the little pond this year. Other years, there have been dozens. I'm pretty sure these two are Mink Frogs. If they were Green Frogs, they'd have dark striping on the back legs and that's not obvious with these guys. I haven't noticed their call but now that I know what it sounds like, I'll listen for it: it's like someone hammering in the distance, or the hooves of a galloping horse.
I have not managed yet to capture these always moving creatures :)
