The Welsh name for badgers is ‘moch daear’ which translates to ‘earth pig’. Badgers live in complex underground burrow system called ‘setts’ that they dig themselves. Family groups live together in setts, typically of around six badgers. Setts have a number of rooms or ‘chambers’ for sleeping in. There are a number of tunnels leading to the outside world. The largest sett in Britain was found to extend over 15x35 meters and had 12 entrances.
