The latest weapon in the battle against pigeon poop has been unveiled - a scary robotic bird.
Ten of the robotic birds have been snapped up by Liverpool council in a bid to protect the city's buildings from mess.
The robot birds look like peregrine falcons - a big enemy of pigeons - and they can flap their wings and squawk.
It's hoped they will frighten off the pigeons - making the poop problem a thing of the past.
The council wants the pigeons to keep to the city's parks.
The public are being asked to help with the clean-up, by not giving leftover food to city centre pigeons.
