Grass Snake

This is a grass snake, found sunbathing near our front door. It is not poisonous.

Do you know the best way to tell the difference between a grass snake and an adder?

Ask the snake what 2 + 2 makes. If it gets the right answer, it's an adder.

This web site is very good for identifying British reptiles.
