I'd agree, and given the late start to the season, I'd also suggest more evidence that young are being carried over this year in slowworms as well as adder and smooth snake. Unfortunately this obscures my original question as to whether this phenomenon is a natural part of the breeding cycle rather than simply a rare response to an unusually poor summer. As always, more data required!

quick update - I finally managed to get a sample of three smooth snakes examined by an expert vet yesterday which all appeared gravid to me, and he was able to confirm that they had reasonably advanced young inside already. So this would seem to show that smooth snakes are not only capable of carrying their young over winter but also that this is a reasonably common thing, rather than a one-off due to an individual snake being in poor condition or an unusually cool summer in the previous year. More data needed, but it's a start. Next question, are these embryos the result of mating last spring, or, as has been recorded recently, autumnal matings...?

...I should have added that he used ultrasound to visualise the embryos.

Very poetic Keith, well put. Shame there's already some kind of pop festival in the field opposite Hartland Moor on Soldiers Road at the moment - one discarded cigarette and the whole NNR goes up in smoke...
