If you look the larger version of the photo above on the right (as we're stalking turtles) you can see a kingfisher in the shadows on the right side of the photo. At least that's what we decided it was. Perhaps one of our birder friends will look a the bigger version of the photo and correct us -- it may be hard to tell due to the image quality from our freebie digital camera.

Correction: Dan points out that actually that's a black-crowned night heron rather than a kingfisher and offered this reference work. For comparision, see this, from the same site.
