Authorities in Liverpool, UK, resorted to robotic falcons perched on roof tops to scare off pesky, fat pigeons!
The mechanical birds - called "Robops" - are to sit on the roofs of buildings, and can be moved around.
They look like a Peregrine Falcon, which is a natural predator of pigeons, and even squawk and flap their wings to scare off the birds.
