Birth control is being trialled as a humane way to limit growing numbers of grey squirrels, pigeons and wild boar
The invention of the contraceptive pill heralded the sexual revolution of the 1960s, and now scientists are looking to revolutionise wildlife control by getting animals in on the action.
Trials are under way in the UK and elsewhere in Europe of how to get contraceptives into pigeons, wild boar and grey squirrels, with scientists also proposingother rodents, invasive parakeets and deer as other target species.
