River Otters Swimming in the Tuolumne River

I've had a real treat of a day. I took my usual morning stroll along the Tuolumne River, catching some decent shots of a Black-chinned Hummingbird, and the back end of a Raccoon (that's not a great picture, but it was the first raccoon I've seen on this stretch of river). Then, totally on a whim, Mrs. Geotripper and I decided to catch the sunset from a high point on the Tuolumne Parkway Trail where the river emerges onto the floor of the Great Valley. We saw some kind of movement in the water, and I realized I was seeing River Otters (Lontra canadensis). My impression is that it was a mother with two pups. It was only the second time I've ever seen them, and this time I thought to catch some video. Enjoy! I'll post a second video in a few moments.
