I searched, and found many threads where people complain of birds using their pool as a toilet. I don't have that problem.
The birds instead live in my pool. Specifically they build nests under the caps on the uprights.
For the last two years there has been a bird that builds a nest under one specific top cap. It just so happens to be where I store my solar cover. It's great when you go to take the solar cover off and a bird comes zooming out of the pool, but I have lived with it.
This morning I noticed that there are two MORE nests in various uprights, for a total of three bird nests in my pool. I guess I could take the top caps off and pack the area under them with something like steel wool (which would then rust and stain) or with something like fiberglass window screening.
Just wondering though, has anybody else ever had this problem ?
And for the record, despite they fact the live in the pool, they do not seem to use it as their bathroom, so it really does not bother me all that much.
