Sand Lizards

Restricted to the Dorset Heathlands, parts of Surrey and closer to the home the sand-dunes of Formby, the Sand Lizard is the rarest of the UK’s native lizards. Fortunately they’re relatively common at the RSPB’s nature reserve at Arne. Apparently the resident Kestrels successfully raise their family each year on an almost exclusive diet of Sand Lizards . Likewise they also form the majority of the Smooth Snake’s diet.

Normally I can get relatively close to reptiles before they disappear into the undergrowth however the Sand Lizards at Arne are unsurprisingly reluctant to break cover. Their cryptic colouring blends into the dead foliage and sun bleached leaves. If ever proof of Darwin’s Theory of Natural Selection is needed these lizards are it. Thanks to the Kestrels only the  wariest of the wary survive.

Male Sand Lizard again at Arne in May 2011. Note the green pigment lost later in the year when the breeding season is over.

About as close as I’ve got to a Sand Lizard.
