Adders (or vipers) are the UK’s only venomous snake and whilst quite a degree of fear still surrounds them from people who picture deadly cobras hiding in their garden these snakes are generally shy and retiring. Indeed if adders were easy to find then we wouldn’t need an article like this – we’d all be tripping over them and instead visitors to this site would be more likely to ask how to avoid adders 🙂
Like all reptiles, adders are fans of warm, dry weather where they can bask in the heat of the sun before hunting for prey. Cool, damp, grey weather tends not to suit them as well and they may well hide away out of view or – in the winter months – even aestivate to conserve vital energy.
Equally so, the warmer a snake gets the more active it becomes – and as it becomes more active so it also becomes faster moving and so harder to spot. The ideal situation to see adders is therefore early on in the morning of a warm, sunny day in summer. The early hours before the snakes get too active and before they get annoyed by dogs and their owners can be the best time so if you’re serious about seeing adders your best bet is to set your alarm and get up bright and early.
As for habitat, adders tend to prefer dry environments such as heathland and gorse-filled grassland. My latest siting of an adder was one hiding just under a gorse bush up ontop of Cissbury Ring in Sussex a short while ago.
Like most snakes, Adders are very sensitive to vibrations through the ground and so it is best to walk as lightly as possible if you’d like to see them – stomping around in heavy walking boots won’t do you any favours – and I prefer to walk slowly and deliberately in flexible trainers so I step as lightly as possible on the ground.
When seen in photographs adders appear to be quite obvious snakes with a background colour varying from olive green through brown to the common silver or grey over-laced with a dark black zigzag pattern down it’s back. However in the wild these markings can make it surprisingly difficult to see and in the right habitat on the right day you may well pass numerous specimens without even realizing it.
While adders can and do climb, they are most often seen on the ground and in the spring time males can sometimes be seen “fighting” for mates as they stand up high and attempt to “wrestle” other males to the ground.
The other British snakes are the smooth snake and the grass snake. Smooth snakes are now very rare indeed so it is highly unlikely you will encounter one while grass snakes tend to prefer damper habitats such as those with ponds and streams.
Consequently a useful tip for getting an idea of whether there are adders in your local area is to keep an eye out for shed skins in the types of habitats mentioned as these will almost certainly belong to an adder and show some recent activity. To slough a skin an adder will normally rub against a rough object such as an old tree stump or sharp bush so keeping your eyes peeled for these signs can be a good indicator that you are searching in the right area.
