While walking in the woods the other day, I saw a brilliantly colored box turtle just off the path in the grass. Being a lover of turtles, I stepped over toward it. What I had not seen in the same grass was a large leopard frog which turned out to be much nearer to me than the turtle.
As I bent toward the turtle, the frog leaped at least six feet. I myself leaped about a foot and a half.
On an earlier walk on the same trail, which skirts something like a creek or culvert, I heard an odd noise in the tall grass between the creek and the trail. I couldn't place the noise at the time, couldn't pair it with an animal, though it reminded me of something.
I moved toward the noise and there was a low scurrying toward the creek and out of sight. I didn't get any kind of look at the creature, but thought I could tell something about its size and shape by the motion of the grass as it left.
A while later it came to me where I might have heard that mysterious sound before, but I wasn't sure. So, I Googled "alligator call" and eventually scrounged up a sound file that matched my recollection of the noise almost exactly. I'm nearly certain it was a young alligator.
