WHERE THE WILD ONES LIVE
Wild rabbits are some of the most skilled builders in nature: their tunnels can be up to 40 metres long and lie several metres deep under the earth. The underground living spaces offer room for up to 50 animals. But their excavations can cause problems on the surface because they can uproot trees. In cities lying on the banks of rivers the consequences can be even more dangerous. There the animals dig their warrens close to flood protection barriers, which makes the protective walls unstable.
ALARM SYSTEM If a rabbit discovers a predator on the surface – an urban fox, for example – it will beat its back legs violently against the ground. The vibrations serve as a tip-off to any brethren under the earth. They can then hide in the system of tunnels deep below the ground. TRAPDOOR Though wild rabbit warrens can be as large as several football fields, the largely nocturnal animals rarely venture far from their construction. The system of burrows has a very shallow main entrance and other hidden openings that are dug almost vertically into the ground. When the animals need to flee, they can simply fall into the hole.
