Vipère péliade ~~ Vipera berus ~~ Common adder

The common adder is only to be found in the north of France, the east of France and the Massif. It grows to a maximum of 90cm. It has a slightly flattened head and is round nosed, eyes with red iris and vertically slit oval pupils. Colouration varies regionally and also between the sexes, males are more varied in colour than females. Their backs can be almost any colour from pale grey to a dark olive green with darker bands which give a zig zag pattern, underneath they are a greyish blue with intense dark marks. They can also be entirely black; these are normally to be found in high regions above the tree line.

They live in a variety of habitats, predominantly where water is present or in damper regions and can also be found in salt marshland but are not found in the warmer parts of France.  It is likely that their range is decreasing with climate change. Prey is sought at dawn and dusk as a general rule, it consists of small mammals, birds, amphibians and lizards.  Unlike other vipers it is a good swimmer and often takes to the water.

Hibernation takes place from October until March / April.

It's probable that the Common Adders range is less than shown on these maps and will be increasingly rare in some places.
