I was at a pond a few weeks back as fall was approaching. I saw some ducks at a pond and my camera was ready to see what they would offer. When you decide to shoot you always want something interesting to occur. There were three Mallard females under a tree.
They got up and moved toward the water.
They jumped in and swam duck paddled from shore.
There was one female Mallard Duck on the other side of the tree and she stayed put. You know me, I moved in for some close-ups.
The duck finally got up and hopped toward the shore. Note; I didn't say waddled.
Anyways; what's with the wing. the duck was standing there on one foot and preening it's feathers.
I was then able to get to the other side of the duck as I walked and made a discovery of why the duck hopped. It had a deformed leg and had to go on one leg. I don't know that this was a serious problem and it could swim fine. I wonder if it can fly.
