I was looking at this thread and saw that JC had mentioned me earlier on, so I thought I'd chip in, for what it's worth, about the Dorset walls.. Originally I had suspected (and perhaps hoped) that the Portland walls might be the reptilian equivalent of the pool frog; ie a native which was overlooked because of the other known introductions of walls elsewhere of predominantly southern European origin. After a few visits to ascertain their distribution on Portland I'm not at all sure this is the case. Although they are northern European in appearance, they do appear fairly restricted to a ribbon along the south east of Portland, and absent from other equally suitable areas (at the moment, at least). This suggests a fairly recent origin. I had wondered whether there was any mileage in the idea of accidental introduction as a result of naval trade between Portland and northern France last century, but again, the limited distribution of the walls seems to suggest a much more recent origin. What I'd like to know is who is putting all these walls into odd places in East Dorset ?! One of the clifftop sites mentioned in previous posts on the south coast of Purbeck is about 2 miles from the nearest village and I would love to know why someone could be bothered to walk so far to this quarry and tip in some walls in the Victorian manner of 'turning out' animals to see if they could make a go of it, particularly when this has been illegal and subject to unlimited fine (in theory, at least) for twenty six years. I also agree that introduction of wall lizards into areas where sand lizards are hanging on seems irresponsible on the part of anyone who claims to be a genuine herpetologist.. I'd be interested to hear whether anyone knows if the various Dorset wall lizard populations are a consequence of one person's activities or a group of people - any thoughts ? Cheers Will

Since colour and pattern of the 'yellow' collar and the black margin vary, could this be used to build up a photo library and to ID snakes subsequently ? Cheers Will

Hello All This is a question prompted by the discovery of a fresh adder slough yesterday (sadly no sign of the former owner) in Epping Forest - namely, I can't remember seeing a sloughed adder this early in the season before. Is this unusually early for SE England and has anyone else seen a slough / sloughed animal elsewhere so far this season ? Cheers Will

Update today from a London site - saw a male shed and then immediately try to mate with a female (as yet unshed) - persistent chap kept up his courtship for over an hour without success. Guess we're at the start of mating for adders (although grass snakes have been seen in London for several weeks in mating balls / clusters) Cheers Will

Had my best grass snake day for many years - gave up counting when I got to 30 animals at my local site, but I noticed that 3 of them (all males) had clearly been feeding on the local frogs / toads - very big bulges in central part of body, complete with protruding elbow / knee joints. I had assumed that grass snakes would be like adders, ie strictly no feeding til after breeding, but these males were clearly intent on the former or both activities. Is this the norm in your experience for grass snakes ? If so, do males and females feed before / during breeding or just males - and if the latter, are these males foresaking breeding for the sake of having a meal instead ? Cheers Will

Hello Brett I posted a photo of a partially melanistic GCN picture in this very forum (UK Reptiles and Amphibians) under the name 'mynewt' in the strand 'how common are red frogs in England ?' (Go back about 6-7 months, I think) This individual - also a male - was from a large garden pond that was lost to a housing development in Enfield, London in 1994. Sorry the photo's not up to the quality of yours ! Cheers Will

I'd echo John Newton's comments re adders getting hard to find - one site of mine has gone down from 25-30 post-emergence to 4-5 adults last week, though I'm still finding grass snakes; I also suspect dry warm weather - reckon some adders have gone from hibernation to aestivation ?! I'd be interested to see what happens when / if it rains in the south .. Will

How easy/ cheap is it to DNA sequence lizard skin / bits of tail ? Will

Hello Martin I'd say yes, given the strongly contrasting black stripes on yellow background; if you see any larger larvae 'suspended' in the water column hoovering up the Daphnia etc then this will confirm it.

Also many females yet to lay, and I saw a couple of pairs of sandies too (photo also attached, I hope - look for the cryptic male's eye !) Maybe the arctic May weather has slowed things down ? Cheers, Will

Great animals though - I have spent time in France, Spain, Italy etc looking for Aesculapian snakes - ironic that my first wild (OK, feral) ones should be a couple of miles from my work.. Cheers Will

will Senior Member Joined: 27 Feb 2007 No. of posts: 330 View other posts in this topic	Posted: 03 Sep 2007 Topic: The Camden Creature Hello Wolfgang The larger snake's size was estimated when I photographed it crossing a paving slab for scale. The smaller one was about 75cm but nothing to allow a more accurate guesstimate. Maybe ZSL have more extensive data which could produce a meaningful average ? Cheers Will
