Since the previous reptile sightings on the 10th of this month it's been far too cold and damp for any self respecting reptiles to show themselves. Today there was heavy cloud cover for a good part of the day and a really chill wind. My wife and I decided to go out for a walk anyway hoping maybe to find some amphibian action (how our Valentines Days have changed!).
Walking past the spot where the Adders were basking last week, we were surprised to find two coiled together on the side of the bank. I believe these two were possibly the same snakes who were basking a few inches apart during the warmer afternoon on the 10th. This time they were coiled on top of each other.
From the 10th.
From today.
Another, well marked Adder was out on the top of the bank nearby.
Walking a short distance further we noticed two snakes coiled together. This time an Adder and a small Grass Snake.
Before I took the photo the Grass Snake was coiled underneath the Adder and moved out onto the top. Unfortunately I think it sensed us watching and after about a minute slipped off into the undergrowth.
The Adder remains on it's own.
Pleased with our unexpected reptile activity on such a cold day we carried on. 50 yards along the bank two more snakes coiled together. Once again an Adder with a young Grass Snake.
Watching from a distance, the two snakes remained coiled together with the Grass Snake more active, moving around and through the coils of the unmoving adder.
A total of six Adders were seen. 2 coiled together, 2 coiled with Grass Snakes and 2 'basking' alone.
I have flipped both species under the same ground cover but not witnessed this behavior before. On our previous visit during warmer weather no snakes were actually intertwined. Are the snakes simply trying to find the best, warmest and least windy spot which happens to be already occupied by another snake. Or, are the snakes benefiting from any heat held by it's partner's coils? I guess when there is more direct sunlight it is beneficial for the snakes to be exposing as much of themselves to the rays as possible and better to bask alone.
Anybody else seen this behavior or have any thoughts, I'd be interested to hear.
