I have an area of paving in my back garden surrounded by a border of broad-bean sized gravel. Something is moving the gravel from the border into a pile over a gap between the paving slabs. Size of pile is approx 14 x 7 x 3 cm. On clearing the pile of stones a hole is exposed about 1 cm diameter. It was stuffed with a dead leaf with the stem of the leaf left poking out of the hole. Who lives in a house like this?
The following morning, some of the stones have been replaced to cover the exposed hole.
ANSWER: Common or garden Earth Worm. The pile of stones is a "worm midden".

I presume you are not in Australia?...
There, there live pebble mound mice, Pseudomys;
"the only mammals to create mounds of small stones around their burrows"
But in the UK, this is most intriguing!
Worms will drag leaves into their burrows, and leave a bit sticking out.
But the piling of the stones... I've never seen that bafore.
I would be most interested to see a movie capturing the creature and its activities.
You might have to set-up a motion-activated web cam, or take up one/both paving slabs (and hope the hole is not too deep).
Also, by way of understanding what's going on, clear the stones from the hole and put an upturned bucket over it, weighed down by a couple of bricks (eg.). Next morning, see what's happened underneath. If stones have magically appeared, they are being brought from underground. ...In which case one thinks:
- mole, or
- mole cricket, Gryllotalpa gryllotalpa (rare in the UK)
