Backyard tree has hole in base that's filled with mud. Should I be worried?

In my back yard there's a tree with a hole at its base. This hole leads up into the tree, and appears to be filled with freshly-tilled mud. Something to be concerned about? (Pic inside)

It's a big, old, healthy tree as far as I can tell. I know there are lots of critters that make their homes inside holes in trees, but I want to make sure this isn't something that's actively weakening the tree. (This is in the Pacific Northwest, if it's relevant.)
