Badger. Badgers are nocturnal and elusive, but remain one of the UK's favourite mammals. Like humans, they are omnivorous, although unlike us, they eat several hundred earthworms every night. Badgers are social creatures and live together in large underground setts, comprised of a series of interlocking tunnels with nest chambers, toilets and several entrances.
