A rabbit warren is a term used to describe a large group of rabbits living in an area. It is usually made up of multiple burrows and tunnels that the rabbits use for shelter and protection. The term 'warren' comes from the Old English word 'wareine', which means 'ENCLOSURE'. Rabbit colonies are often found in fields, meadows, and other open areas where there is plenty of food and shelter for the rabbits. Warrens can be home to hundreds of rabbits, and they are often seen as a nuisance by farmers and gardeners.
