There's a cavity in that stump and this male pileated woodpecker has been dipping for the contents, which I've filled with a homemade "suet" mix of Crisco, peanut butter and cornmeal. I've also had a female pileated visiting. (She doesn't have the white stripe extending back from the beak.) Many insect eating birds have visited the cavity in this log. It sure has made the winter pass quickly watching the visitors it has attracted.
