141 of 365 Nature's doorways

On a wander around the yard, I noticed these "doors". I am not sure who's abode they are, for sure, but I think the above is where our resident opossum lives when he is not checking out the droppings from the bird feeders.

To the right is one of the many large tree stumps. these holes could be homes to many different birds or small mammals... and maybe several sequentially!
