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 d
o 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.
