The rat population at Cosmeston Lakes Country Park is thriving thanks to the generosity of those folk who leave seed for the birds. The rodents are fearless opportunists and extremely cheeky, approaching to grab their share of the bounty even before people have stepped away, but they do at least share the seed with the birds. The rats stuff their mouths full of seed and scuttle away, whereas the squirrels monopolise the seed, staying put and not allowing the birds to approach.
