This handsome bird is a male Ring-necked Duck, but not a happy one. I spotted him splashing in a small lake where a tangle of thin tree branches hung low over the water. A duck having a bath, I thought. Then, as he took a break from splashing and his head drooped so low that his bill went under the surface of the water, Maybe not.
His right foot was caught in a snarl of fishing line and attached to one of the submerged tree branches. The foot was bloody and, from what I could see, the leg broken, probably as a result of his attempts to free himself. There was absolutely no way he could have escaped the fishing line on his own: it was wrapped many times around his foot, the branch, and other branches. It probably caught his foot loosely at first, while he was diving for food; then, as he tugged at it, pulled tighter and tighter, until he was trussed to that branch and pulling against his own flesh when he struggled. Fishing line is made not to snap.
