Mystery burrow

OK. Here's a challenge. Does anyone know who might have made this hole?
I found a bunch of them on a recent hike in Rancho San Antonio park, in Cupertino, California in early February. They were all over the hiking path. They must have been made earlier that morning, because the dirt was still moist. The hole is about half inch in diameter. Tarantulas, maybe?

Hmmm...I wish I knew more about this stuff, but I'm really not sure.

I would guess sme kind of ground-nesting bees, unless you have exceptionally large ants in those parts.

I would agree with 'the cunning runt,' I have seen similar holes before and they were caused by wasps of some sort.
