LOL, Pickles your mudhole is funny. Mine found a pond in my backyard that I didn't know was there. The tree covered a ditch and it is blocked so it forms a pond. It has clean flowing water too so it is great. I too have a mudhole thou, its my whole backyard. About 1/2 and acre. They went around when it was wet (it rains here lots) and went and "dug" for worms with their beaks. You can walk around and see little holes, people always ask me what the holes are from, I say the ducks, then I get very strange looks. I have to explain how they do it, and you can always tell who the guilty one is, they always have mud up to their eye balls.
