In front of the patio to the front door of my house there is a stump where the previous owners had cut down what must have been a large tree. Aside from the occasional decoration, this trunk remains largely unused by us. However, we all like it so there it stays. Now, I understand why… today a pair of Boreal Chickadees started to dig out their hollow to make their nest. They carried out small clumps of wood pulp clawed out on every trip. I hope they choose to stay here.
