I need something that won't disturb my neighbours' and rid my large tree of
birds. They are making a terrible mess under the tree.

Thank you.

Ultrasonic devices dont work on birds, neither do fake owls, hawks,
and snakes. What did work for me is a box that makes various bird
warning sounds but this may disturb the neighbors or maybe not.

OWL to be working, owls must be hunting the birds in that region. Animals do not fear from other animals in a predefined context.

And sounds, which may work for a specie might not work for others.

So, for example, in a closed hangar or workshop, why would pigeons stay in? Coz of shadow, shelter, and stable heat/wind i assume.
