A Collection of Adders

 The Adder (Vipera berus) will be heading into hibernation during the coming weeks but they can still be seen sunning themselves on warm autumn days.

Males generally have the more contrasting markings. The zig-zag marking along its back is normally black with a paler ground colour to the rest of the body.

Females are generally of a more reddish-brown colour.

In some populations, melanistic Adders can be quite common.
