Lovely roe deer, stonechat and smooth snakes on a local heath

Here is one of our most endangered reptiles. These snakes are so elusive and fossorial that almost nothing is known about them. They are thought to be constrictors that feed mainly on other reptiles, especially lizards. Who knows. Other snakes certainly don't seem to fear them greatly.....I wonder what you think. They are often found in the same places as stonechats and roe deer are found.
