I came across this little guy one day while photographing herons. I'm not a turtle expert, but I believe it's a Red-eared Slider. He was trying to sun himself on the bank, but wasn't up quite high enough to actually get the sun. If you look at the last photo, you can see what I guess are very tiny aquatic insects on his head. I didn't see them until I got home and looked at the photos in actual size.
