Feeding
Diet consists mainly of small mammals, such as mice, voles, and shrews, as well as lizards. Sometimes, slow worms are taken, and even weasels and moles. They feed on amphibians, such as frogs, newts, and salamanders. Birds are also reported to be on the menu, especially nestlings and even eggs, for which they will climb into shrubbery and bushes. Generally, diet varies depending on locality. Juveniles will eat nestling mammals, small lizards and frogs as well as worms and spiders. Once they reach about 30 cm (1 ft) in length, their diet begins to resemble that of the adults.
