Tufted Titmouse in Pennsylvania

Spending Thanksgiving holidays in Pennsylvania provides an opportunity to renew some old aquaintances, such as the Tufted Titmouse that enlivens the chilly woods along Perkiomen Creek. They behave much like Chickadees, and I often see them in the same patch of woods. They must utilize different resources or features within the same habitat, but I have not yet been able to identify the differences.
