Common wall lizards from Shoreham Beach, both green and brown forms were seen
No interactions present.
I think I have read somewhere that the Shoreham colony derives from Italian lizards that escaped from a local collection
Yes, that's right, the green ones are definitely Italian in origin. I wonder if some might be from elsewhere because in most of northern and western Europe they are brown.
Apparently there were some Italian wall lizards Podarcis siculus also escaped from the same collection, but these were pretty soon outcompeted by the common wall lizards which cope a bit better with the British climate and there are none left now.
