Ringed Snake

Ringed Snake (Tropidonotus natrix), the common snake of Britain, very often found near water, whence it is sometimes called the water snake. The upper parts are brownish-grey, marked with black; there is some yellow on the head, and the under parts are lead-blue, sometimes marked with black. These snakes, which are quite harmless, feed on frogs, small fish, lizards, birds and their eggs, and mice.
