Lovely photos, have been out in this warm weather trying to photograph some, but so far haven't found any despite being told of some good locations!

Great photos

What great photos - you can very clearly see the different colouration of males (greyer) and females (browner).

Courtship -

this looks like early stages of courtship - the female certainly looks plump enough to breed this year.
A lady called Sylvia Sheldon learnt to identify all the adders she found by the patterns between the "V" on the head and the top of the zig-zag down the spine. She photographed them and carried a little book of the cut-out pattern around with her on surveys.
The markings on this female are a good example of how distinctive they can be.

Not many adders yet!

I usually expect to see loads of adders at this time of year. So far I have only seen two.
