Look for Sapsucker "Cafes"
Woodpeckers called sapsuckers drill neat rows of little holes in trees, then slurp up the sap. (See the illustration, above.) Chances are the tree will be an old sapsucker café—where the bird's holes have dried up and healed over. But if you're lucky, you may find a fresh one—where the sapsucker holes are still oozing sap. You may get lucky and see not just sapsuckers, but hummingbirds, insects, and squirrels stopping by to dine.
