Daylight robbery: grey squirrels stealing millions of pounds of bird seed a year

New video analysis reveals the furry thieves are looting up to half the seed put out in feeders, leaving gardeners and birds short-changed

Daylight robbery worth millions of pounds is taking place in gardens across the country with grey squirrels raiding bird feeders on a huge scale, new research has revealed.

The crimes were caught on video camera by scientists, who said grey squirrels are also known to raid birds' nests for eggs and chicks. So people putting out food for birds are inadvertently supporting a species that harms them.
