The town of Liverpool has released Robops on their rooftops. Following the same principle as keeping ceramic owls to scare away smaller birds, these next-generation robotic falcons are meant to deter a number of obese pigeons in the city who seem to be growing of late because of their fast food diet. The bots screech and flap their wings to scare them away.

The City Council is hoping that the pigeons, who swoop down on residents and leave their droppings everywhere,  will relocate to greener spaces, where they will only be subjected to a better diet of seeds and insects. That might work, but we bet there will be a few renegades who will seek out fish and chip vendors.
