GRASS SNAKES ~
There are quite a few pairs of breeding grass snakes on Hampstead Heath.
Grass snakes are non-venomous and City of London has built small ponds and woodpiles to encourage them as well as other animals.
Some live around The Bird Sanctuary Pond and in 2010 it was estimated that there were about thirty breeding pairs on The Heath.
The grass snake is Britain's largest terrestrial reptile.
It is a fast-moving and wary snake.
Mating takes place from March to June.
It eats frogs, toads and newts, although fish, small mammals and young birds may also be taken.
