This one falls less into the "blooper" category and more into the "no good deed goes unpunished" category.
Towards the end of spring last year, I was fishing and worked my way to the back of a small cove. There is an abandoned launch ramp there, fenced off to stop non-residents from launching boats on it. Using the ramp as a beach were a pair of black Australian Swans, who were tending to their 3 cygnets (baby swans). There are about 18 Australian swans on our lake, all from 1 breeding pair that was brought in about 7 years ago. Since this is the only home they have ever known, they have no fear of nor animosity towards humans, they look at us as potential feeding machines.
As I got closer to the swans, I heard a cry emanating from the opposite direction. I look over and a baby Canada goose, maybe 2 months old or so, has lost his way from his parents and in a panic, starts swimming towards the swans. Immediately, the male swan takes this as an act of aggression and begins swimming towards the gosling. Knowing what is about to happen, I pull my boat between the swan & the gosling, only to have the gosling dive under water, swim past me & the swan and pop up at the boat ramp right next to the cygnets. All hell breaks loose! The adult swans pinned the gosling against the fencing and began hammering it with their beaks, feet & wings. The gosling kept trying to get through the fence to get away, but couldn't. I quickly got my boat up next to the retaining wall, and went over towards them. The swans stopped, calmed down and just watched as I lifted the bottom of the fence up so the gosling could get on the other side. No worse for wear, the gosling kept squawking, running down the shore trying to find his parents while the swans went back to their brood. Feeling like Dr. Doolittle, I turned back to my boat...which was now floating in the middle of the cove.
