The Adder is a relatively small snake, rarely much longer than 50cm and quite thick set. Prefers woodland, heathland and moorland. It hunts lizards and small mammals as well as ground-nesting birds such as Skylark and Meadow Pipit. Hibernates from October, emerging in the first warm days of March, which is the easiest time of year to find them.
