Yesterday I found tracks in Scarlett’s sandpit and tentatively identified them as coming from a mouse.  Well, I was wrong.  Not the first time, won’t be the last either.

The tail drag was the clue, but I didn’t think it through enough.  One animal consistently leaves a tail drag – a lizard.  I thought about this, but I ruled out a lizard as the source of the tracks because the tail drag was too small.  Lizards don’t just drag their tails, they walk with their legs sprawled so their whole body drags on the ground.  This means that their footprints are spread wider than the body and that they leave a fairly broad drag mark.  In other words, like my tracks, but smaller.

I should have paid more attention to the shape of the trail, and less to its size.  Let me pose the question: what leaves tracks like a lizard, only smaller?  The answer: a small lizard.

Obvious really, in hindsight.  The tracks were made by a small lizard.  How can I be so confident now?  Well, I found the poor little chap in the sandpit this morning, dead.

Common Lizard

It’s a Common Lizard, I think (slightly less common now…) and only a tiny one. He’d obviously climbed in and couldn’t climb out up the smooth sides.  It was a hot day, and he must have succumbed to the heat.  Despite Scarlett and I playing in the sand for half an hour yesterday, we didn’t see him.

Perfectly obvious, with hindsight.  The lesson for me is to think through possibilities when tracking, not make assumptions.
