ADDER
Once common in many parts of the UK, the Adder has significantly declined, with pockets of good populations largely confined to heathland & moorland nature reserves. In Montgomeryshire, there are barely a handful of known sites supporting this much-maligned, native, venomous snake. We need your help to find more!
Take a look at the three species outlined below, paying particular attention to the key features described. If you think you have seen an Adder, please report your sighting to Tammy.
More about Adders...
The Adder is Britain's only venomous snake, but hardly deserves its vilainous reputation, as it is rather timid.
Bites from Adders are very rare and mostly occur when a snake is handled. In most cases reactions to Adder bites are mild, although medical advice should be sought, just in case. Cats and dogs do get bitten, but these bites also rarely prove fatal. Gardeners reporting a bite from an Adder are more likely to have had a close encounter with a spider (several British species can deliver a painful bite) or a rose/bramble thorn.
Adders are easily distinguished from other snakes or the Slow-worm by having a bold zigzag stripe down the length of their back. They are most likely to be confused with a Smooth Snake, but this rare snake is not found in Montgomeryshire.
Colour is very variable, but is typically different in males and females.

Male Adders tend to be off-white, grey or yellowish, whilst the females are brown. Young Adders look like miniature females. Black Adders are also occasionally seen.
As well as the zigzag pattern already described, Adders have a 'V' or 'X' mark on the back of the head. The large eye is red and has a vertical pupil. The head is broad and angular with an upturned snout.
Despite their stocky appearance, Adders never grow big, rarely exceeding 60cm in length.
Where & how to see Adders
In Montgomeryshire, look for Adders in open habitats such as heathland, commons, moorland, open woodland, woodland rides, road and rail embankments.
The best time to look for Adders is in the Spring when they have just emerged from hibernation and the vegetation is still quite short. They also spend long periods basking in the sun to warm themselves and can be preoccupied with finding a mate, or fighting off a rival.
Walk lightly & slowly in suitable habitat, pausing regularly to scan the area for any sign; binoculars are invaluable.
If you are lucky enough to spot an Adder, remember to treat it with the greatest respect; do not get too close and never attempt to catch it.
