Mallards are probably the most common wild duck species in the world. They adapt easily to different environments and are considered an invasive animal.

Some of them are not afraid and certainly don't have any notion of private space, even invading swimming pools.

Cases of ducks using the pools as a water source have been reported many times across the world.

Ducks love pools, especially during the nesting season. So they are probably there because there is a nest nearby or there is food, like plant materials and worms.

Migratory birds are under protection around the world. If the bird has made its nest somewhere near the pool, do not chase them away because the female might abandon the nest. There is no other way than wait for them to leave or get professional help. You can also cover the pool when nobody is using it.
