The reason for this picture is the Red-Bellied Woodpecker (which has a very red crown and nape, but almost no red on its belly), but so many other things are happening with this tree. There is lichen and moss and a fungus, and some smartweed growing from the crotch of the tree itself. And, of course, the woodpecker is there because there are tasties under the bark. It helps one appreciate all that is going on in nature.
