Leg waggling!

Perfect conditions for watching reptiles today. Spent the afternoon watching lizards in the garden and also found a sub-adult grass snake which was nice.

Observed a behaviour for the first time. Only one large female was about and a number of sub-adults and juveniles. 3-4 large males actively seeking mates.

When the males approached the female (who already looks like she might be gravid) and the sub-adults I witnessed a fascinating behaviour. They supported their weight on their bellies and waggled both front legs frantically. This appeared to be a 'I'm not interested go away' message (as opposed to a 'I'm here come and get me'). Just wondered how many others have osbserved this behaviour in Lv or other species.

Tried for ages to get it on film, but as  you can guess all the waggling stopped when I got back outside with the camera.

Tried again to film it no luck, but did find two more grassies, both juveniles from last year (so all that work on the compost heap was worth it!!), silly Youtube vid of one of them:

Hi Gemma,

               The behaviour that you have witnessed in your Common lizards is not unusal . I have seen this sort of thing happen fairly frequently in both wild and captive sand, green lizards . I too would agree that this sort of posturing would indicate a nervous responce from the animal .

Tim, I think most people would be suprised how tiny the area in our garden actually is, just 4 years ago it was plain lawn with no chance of reptiles living there. 

With a bit of thought like putting in a hibernation bank, log and brash piles, a pond and compost heap and letting nature do the rest with minimal management it was very quickly colonised and the best bit it now supports breeding populations of both common lizard and grass snakes. 

Shows how quickly nature will get the upper hand if pushed in the right direction and is then left to get on with it.

I based the 'go away' message mostly on the sub-adults that showed the behaviour.

They were too young I believe to mate though the males would have a go at a neck grab. Once the sub-adults were free they were doing the leg waggling - it is interesting that there are differing interpretations of what it might mean based on direct observations, suggests to me it might be a quite complex behaviour with different signals being passed depending on the circumstances, i.e. receptiveness, age etc, so we might have observed different reactions and different signals being passed by the same behaviour

Oh damn I will have to spend several years trying to film them now in the garden to better understand it all..
