Yes, Birds....

If those are culled fish that's a good wallop. You can loose that number overnight if a flock lands. Oh yeah, American Pelicans as well. They are a treat to watch. They land as a flock and start at the edges of the pond and heard everything into a tight ball in the center. Once there they gorge themselves. It's the opposite for most diving birds. They work from the center out where the Herons and Egrets are waiting along the shore. Also, brood stock can be taken by Osprey and Bald Eagles. I don't want to scare you, but plan for it.
Thanks for the head's up, Richard. I haven't yet forgotten about losing my favorite koi ever to a heron, and we have every one of the feathered predators you've mentioned, right down to the pelicans.

I don't want to scare anybody, but I'm probably going to utilize hotwire against the wading birds. One touch of that and they'll think they just met God and he wasn't very happy. As far as the diving birds, it'll probably be monofilament line criss-crossing over each pond in a harlequin design small enough to (hopefully) ferhoodle the most diminutive of divers. And hopefully it won't be aesthetically unpleasing. Maybe I'll grow a network of vines suspended as cover...there's no telling what I'll come up with between now and then.

Besides green lasers, what else in your experience have you used on your ponds to deter predator attacks? What worked and what failed miserably?
