I can't tell you how much pleasure it gives me to discover a grass snake in our garden and to be able to photograph it basking in the sun (the first sun for two weeks I am told). It is lying on a compost heap where apparently they often lay their eggs. It is a sign that our garden is supporting the sort of wildlife diversity that we have long hoped for. The bulge towards the tail is either an unfortunate amphibian, or perhaps some eggs. Long but not venomous, and sometimes called ringed because of the yellow collar around its neck.
Close inspection of the photos shows two, possibly three orange/red blobs on the back of the snake's head. These are snake mites (see
link). What a strange rich world we live in.
