The Catalan town of Badia del Valles will use three automatic dispensers to scatter the required dosage to the pigeon population every morning.
Each pigeon will be fed 10 grammes of Ovistop, a product made of corn seeds covered in Nicarbazin, which acts as a contraceptive for the birds.
The first dispenser was installed yesterday near the town's Civil Guard headquarters, while the other two will be installed on school roofs next week.
The pigeons will be put on the birth control pill from July until December, the high season for pigeon breeding, 'The Local' reported.
