ZEP, i do see where they have made the pier a place to eat and poop. Goes in one end and out the other. Now don't missunderstand but i find the bird device a little more than what I might do.
Look at what some of us, and all we do to keep Mother Nature from effecting our plans with our ponds. I find it all a little funny, including even what i have done at the pond over the years. And for me, i am not sure anything i did other than otter traps have done little to disturb the other creatures that come to the pond.
