Spiteful Birds

We had the exact same thing happen to our last pool a few years ago, but they were droping it on the cover.

Someone told me that it's instint, that birds will spread there poop all over the place, especially in wet areas to facilitate habitat. Their little instinctive brains know they have undigested seeds in their poop and they spread it around.... Go figure...

Birdbrains......guess they're starlings or common grackles - PIA birds!
I currently have a ton too, (Poop that is) and am finding bloated dog food in the pool, my dog's PO'd too because he certainly didn't ask to be put on this crash diet, poor guy spends half his day chasing the birds away from his precious food and water, the other half looking for rodents to supplement his skimpy diet.
He doesn't even want to come in at night anymore, just wants to sit near his dog dish, on guard.....poor guy, this is going to give him a breakdown before the end of the summer.....

Grackles. What a joy. We didn't have much trouble the first couple of years in town. Then word got out that we had a water source and we've been bombarded with poop packages. It is an instinct. They intentionally clean their nests and dispose of the packages into or next to a water source. Mostly it doesn't affect chemistry other than the need to shock more frequently when they are nesting. Keep your eyes open though, because if they have babies die in the nest, they will clean that too and deposit it into the pool. That definitely gets me to shock the water.

Last year we had three nestings because of a long spring. sigh...
