How do I control, not necessarily prevent, birds from coming to my garden pond?

Hi ther! So I've posted before re: garden ponds. At first it was murky water, then dead birds, and now... too many birds! I love nature, but the old addage "too much of a good thing" definitely applies to my pond. I don't mind birds seeking water, a quick bath, etc. (after all, that's the point, I know), but I seem to be getting TOO many visitors. Today I cam ehome to an abundance of bird excrement in, on and around the pond. Had to drain it again (gross), clean the stones and water in the stuff on the plants surrounding. Is there any thing to help "control" the feather friends, or should I just fill in the hole and give up? For health reasons, smell and ultimately just plain appearance, I can't have another day like today. Thanks for your suggestions!

Buy a bird bath as an alternative to using your pond. No guarantees , but better than netting the area. How many, and which types of bird can cause you to drain your pond ? Surely only Ducks ?
Reply:I know someone with a biggest up grown swimming pool converted into a pond. Yes, he lost many fishes to Hawks and Eagles. One day afternoon, my neighbor saw a big Hawk standing on the edge of his pond eying his Koi (s), like 50 Kois. Yes number of Koi's did vanished from his pond. I say "Alien abduction." Solution. He found some floating seaweed that Manatees like to eat and grow enough of them to cover his pond and also he cover his pond with screens from Home Depot. They sell them by the yards. Good luck. Now he has problem with racoons !
Reply:I scare crow would be best. Or other wise you can take a black water hose and cut it up into 4 feet long strips or black boarder line for above ground gardens and that will scare the birds, b/c birds are afraid of snakes.
Reply:Blow up a balloon, tie it to a string. Tack the other end of the string down in the area. The balloon will blow around in the wind, and scare off the birds. You can also try tin foil, in the same way. The sun shining off it will also scare away birds. Regards-Bob.
