Actually, two. One looked very much like a fox digging out a
mouse, but the other was fairly neat, 6" in diameter, and turned
a corner. That's a damn small fox! I could easily get mink,
but I didn't think that they dug much. Any ideas?

A test boring for a vixen's birthing den? T'is the right time of
year.

Vixen aren't THAT much smaller! The second hole was such that
I don't believe a fox of either sex could have got in without
making the hole a lot larger. The material doesn't have much
structural integrity.

The test boring obviously failed to find a suitable site. I have had
to fill in more than one test excavation of that ilk. The daft
b*ggers are quite prepared to dig down towards the foundations of
walls. Made a mess of my strawberry patch last year. And a patch of
lawn.

http://en.wikipedia.org/wiki/Red_fox makes good reading regarding
their digging techniques.

Please let us know when you identify the culprit.
