basking near a shared hibernaculum, I'd guess.
This is a brown female.

I'm not so sure. The eye "brille" is fogged, which suggests it is about to slough. Male skins do look browner at that time, and the zig-zag paler.
However, you're the expert, so I can't argue with too much confidence!
Hello Roger, you are right, the eye is blue a sure sign it is sloughing its skin (the eye is usually a red colour). I should have looked more closely.
The two animals on the right are different to the one on the left, they look to have just completed a sloughing. The markings are very strong indicating males but the colour is definitely brown indicating females - though colour is variable, e.g. 'black' adders.
The left one aside which is almost certainly a male sloughing its skin; I think you may well be right on the other two being males as well, simply because they look very slim, females tend to be a little fatter than males. Length may help, males are around 50-60 cm whilst females are closer to 80-90 cm.
Sorry for the confusion, I've been away for a while and in trying to catch up I did not look carefully enough, that'll teach me. As for being an expert, that is an iSpot term for someone who is knowledgeable, I wouldn't call myself an expert. I can make mistakes and am always learning; if there was not always something new to learn life would quickly become very boring!
though I was fortunate enough to do some work with Sylvia Sheldon in Wyre Forest years ago. She's now using radio tags, which will make life more interesting!
I just came to like and respect these inoffensive, maligned, and sadly declining beasts.
Radio-tagging snakes, interesting!
Nothing to tie them to and if you glue them on surely they will be sloughed off. Also would they not interfere with the snake's movement? Radio tracking mammals and birds is hard enough, but snakes?
they have surgically inserted the trackers, but adders are too small. You have to wait until after sloughing, and allow a few days for the skins to roughen up again, apparently. They the tag won't slip off. The trick is to have a tag design that isn't going to snag on anything. It will be lost at the next slough, but could be collected and re-used, I suppose.
All this is second-hand, as I no longer live anywhere near Wyre. Shame.
Yes, I can see that would work. However, they probably don't retrieve the tags as the battery life on such a small one would only be a few weeks, couple of months tops.
