The pigeon population in Tongeren has fallen by 28.4% since the start of the treatment with R-12 six months ago. Tongeren is the first city in the Benelux region to feed its urban pigeons R-12.
Following the use of contraceptive feed in the city of Tongeren, GAIA called on other towns and cities to follow this example. It’s an efficient, animal-friendly and selective method that avoids cruel gasification, according to GAIA.
