I now know the difference between a peeper frog call and a wood frog call. (Wood frogs sound like ducks and peepers sound like, well, peepers. You can hear them both in this video.)
I watched a fox trot all over our yard this morning.
We either have a mouse in the house or our dog is staring at something out the window. I'm pretty sure it's the latter, as the cat has absolutely no interest. But she's unpredictable, so you never know.
