Rat holes and vole burrows

I could have sworn this hole, which appeared in January, was made by a rat because there was a spoil heap outside it. Rats dig down, kicking soil behind them, whereas water voles dig up from below using their teeth which means their entrances are neater. But either I was wrong, it was always a vole burrow, or the rat's gone and this vole's taken the burrow over. Does this happen?
